Learn how to make homemade poppy seed filling for kolaches, kolacky cookies, buchty buns, or yeast breads. These are all traditional Czech pastries that call for poppy seeds, and once you have a good Czech poppy seed filling on hand, all of them are within reach. Let's dive into the recipe!
Czechs are the world's largest producers of poppies, so it is no surprise that poppy seeds have become a staple of Czech cuisine. The filling is based on ground poppy seeds cooked in milk, sweetened with sugar, and flavored with little extras. I will show you the spices that make it taste truly Czech a little further down.
➜ Pronunciation
The Czech name for this poppy seed filling is maková náplň. I recorded a short audio file for you, so click to listen to how a true Czech says it.
MY TIP: This filling is great for a poppy seed roll - another classic Czech pastry!
➜ Poppy seeds in this recipe
For this filling, the poppy seeds need to be ground; whole seeds will not soften into a filling. Whole poppy seeds have their place, of course. They are great on top of Czech Rohlíky or sweet Loupáčky rolls, but that is a different job.
In the Czech Republic, we buy blue poppy seeds either whole or already ground. If you live in the US, you can usually find them in European deli stores (Polish, German, or Ukrainian), though they are most often sold whole. That means you will need to grind them yourself.
The short version: grind the seeds dry, in small batches, using a poppy seed mill or a clean coffee or spice grinder. Pulse in short bursts, so you do not turn them into an oily paste. Skip the food processor; it does not work.

Ingredients worth a closer look
You will find the full ingredient list with amounts in the recipe card below. Here are the few that deserve a word before you start:
- Poppy seeds, ground in a mill or coffee grinder (see above) - the heart of the filling.
- Jam, choose one with a distinctive, lively taste. I used red currant jam in this recipe, and it is lovely; prune jam (the Czech favorite), raspberry, or apricot all work beautifully too. Really, any solid jam with real character from your pantry will do. (Wondering why jam at all? It makes the filling juicier and rounds out the flavor.)
- Czech rum, for that warm, traditional note - more on the best US alternative just below.
A QUICK TIP: How to tell if your poppy seeds are fresh. You can tell whether poppy seeds have gone bad by their smell and taste. Rancid seeds taste bitter, and a bitter batch will spoil the whole filling, with no saving it once it turns. When in doubt, give them a little taste before you start.
➜ Best spices and add-ons that make poppy seed filling taste truly Czech
This is where a simple filling becomes a Czech filling. A few well-chosen flavorings lift ground poppy seeds from pleasant to nostalgic - the taste so many of you remember from a grandma's kitchen.
- Czech rum is the classic. At home we reach for tuzemák or Božkov. If you are in the US, the closest stand-ins are Kirkland spiced rum (from Costco) or Austrian Stroh. Both taste close to Czech rum and are what I recommend in my rum balls too.
- Ground cinnamon adds gentle warmth.
- Cloves, ground or finely crushed, bring that deep, festive note.
- A spoonful or two of jam, preferably prune or red currant - stirred in adds a welcome juiciness. And here is another old trick: some Czech cooks grate in a little gingerbread (perník na strouhání), either to deepen the flavor or to thicken the filling if it has turned out too thin.
- Want more ideas? Rum-soaked raisins are wonderful stirred into the cooled filling, and some bakers add a little freshly grated lemon zest for brightness. Add these extras to taste once the filling has cooked.
➜ Instructions with photos
STEP 1: Combine the ground poppy seeds and milk in a medium saucepan.
STEP 2: Bring the mixture to a boil over medium heat, uncovered. Stir occasionally so the milk and poppy seeds do not burn. Add the sugar, jam, ground cinnamon, and crushed cloves.
NOTE: In the photo below, I also added a little grated lemon zest.
STEP 3: Reduce the heat to medium-low. Cook until the sugar dissolves and the poppy seeds soften, about 10 minutes. Stir often.
NOTE: If the poppy seeds absorb all the milk, add a little more, but not too much. As the mixture cooks, the liquid evaporates and the filling becomes thicker.
STEP 4: Transfer the finished poppy seed filling to a bowl and let it cool completely.
MY TIP: To cool the filling more quickly, spread it in a thin layer in a large baking dish.
✅ What does "done" look like? You are aiming for an easily spreadable, paste-like consistency - thick and cohesive, with no liquid separating out. Don't worry if it looks a little loose in the pan: this filling thickens as it cools, so always let it cool fully before you judge it.
➜ Troubleshooting: getting the consistency right
Even simple recipes have their moments, so here is how to rescue yours.
My filling is too thin. First, cook it uncovered. As the poppy seeds and milk simmer, some liquid evaporates and the filling thickens. Remember it will firm up more as it cools, too.
If you would like to thicken it further, in the Czech Republic we stir in ground or finely crushed piškoty crumbs. In the US, Nilla Wafers are a great stand-in, or any plain wafers without filling. My mom likes to add a little krupička and cook it a few minutes longer. In the US, Cream of Wheat works well, and elsewhere fine semolina does the job. Another traditional touch is a little grated gingerbread, called perník na strouhání in Czech.
My filling is too thick. Easy fix: stir in a little milk, or even better a splash of cream, until it is soft and spreadable again.
The milk all absorbed and there is nothing to boil - will it burn? This can happen if the seeds are very finely ground or the heat is too high. Add a little more milk (not too much), lower the temperature, and stir constantly while it comes back to a gentle boil. That brings it right back.
Useful tips
- Can you save time with store-bought? If you are in the US, you may be able to find SOLO brand poppy seed filling, which is ready to use in sweet pastries. It is a fair shortcut when you are short on time. Though, like most readers will tell you, freshly ground homemade really is in a different league.
- Make only what you need when you can, since the flavor of the poppy seed filling is best fresh.
- Tip for filling: When you are filling smaller pastries like Czech kolache or kolacky, spoon the filling into a piping bag first and pipe it neatly onto the dough. It is much tidier than using a spoon, and you get an even amount in every one.
- Got leftovers? Store the cooled filling in an airtight container in the fridge and use it within a few days. If you do make a big batch, divide the cooled filling into small portions and freeze them.

FAQs
The easiest way is a dedicated poppy seed mill - a mainstay in Czech kitchens. A clean, dedicated coffee or spice grinder also works; just grind in small batches and pulse, so you do not end up with oily paste. Always grind the seeds dry.
Czech rum (or Kirkland spiced rum / Stroh in the US), ground cinnamon, and a little crushed cloves are the classic trio. Rum-soaked raisins, vanilla or a touch of lemon zest are lovely additions too - stir them into the cooked filling.
You can - SOLO brand is the usual one in the US. It is handy in a pinch, but freshly ground homemade has a depth that the canned version cannot quite match.
Keep it in the fridge in an airtight container for a few days. For longer storage, divide the cooled filling into small portions and freeze - it freezes well and thaws ready to use.

📖 Recipe
Czech Poppy Seed Filling (Maková náplň)
Tap or hover to scale
Ingredients
- 2 cups ground poppy seeds
- 1 ¼ cup milk
- ½ cup granulated sugar
- 2 Tablespoons jam e.g., prune jam, red currant, raspberry, or apricot
- ¼ teaspoon ground cinnamon
- ⅛ teaspoon ground cloves I used whole and ground
- 1 Tablespoon rum the perfect Czech touch
Instructions
- Combine 2 cups ground poppy seeds and 1 ¼ cup milk in a medium saucepan.
- Bring to a boil over medium heat, uncovered, stirring occasionally so the milk and poppy seeds do not burn. Stir in ½ cup granulated sugar, 2 Tablespoons jam, ¼ teaspoon ground cinnamon, and ⅛ teaspoon ground cloves.
- Reduce the heat to medium-low and cook, stirring often, until the sugar dissolves and the poppy seeds soften, about 10 minutes. If the seeds absorb all the milk, add a splash more; as it cooks, the liquid evaporates and the filling thickens.
- Stir in 1 Tablespoon rum. Transfer the filling to a bowl and let it cool to room temperature before using.
Notes
- Makes about 2 cups of filling.
- Use ground, not whole, seeds. Whole poppy seeds will not soften into a filling. Grind them dry, in small batches, in a poppy seed mill or clean coffee/spice grinder. Pulse in short bursts so they do not turn to oily paste. Do not use a food processor.
- Pre-ground poppy seeds? Use about 1¼ cups ground for every 1 cup whole seeds. Always check they are fresh - rancid seeds taste bitter and will spoil the batch.
- Done = easily spreadable, paste-like, thick and cohesive, with no liquid separating. It looks loose in the pan but thickens as it cools, so let it cool fully before judging.
- Always use the filling at room temperature, never hot. Hot filling can kill the yeast in yeast dough (so it will not rise) and soften butter-rich doughs. Cool it down, or bring it up from the fridge, before filling pastries.
- Too thin? Cook uncovered to evaporate liquid, or stir in a little of any of these to thicken: crushed piškoty / plain wafers (Nilla Wafers), Cream of Wheat (krupička) cooked a few minutes more, or grated gingerbread (perník). Too thick? Stir in a little milk or cream.
- Storage: keep cooled filling in an airtight container in the fridge for a few days, or freeze in small portions. Flavor is best fresh.
- Tip for filling: When you are filling smaller pastries like Czech kolache or kolacky, spoon the filling into a piping bag first and pipe it neatly onto the dough. It is much tidier than using a spoon, and you get an even amount in every one.
David says
Poppies are really hard to get here (Michigan), so I got to make this only once when my cousin sent a packet full of poppy seeds from the Czech Republic. Even then, this tasted fantastic! I think that poppies are really underrated in the US.
Petra Kupská says
Ahoj David, poppy seeds are one of the most commonly used ingredients in the Czech Republic when it comes to making filling for kolache and buchty buns. Always a great choice!
Marlyss says
FYI, canned poppyseed filling is available in grocery stores. Is on the baking isle with pie filling.
jesk says
Be forewarned, store-bought canned filling is hardly worth it; it's overly sweet and lacks a depth of flavor. Once, my grandma switched to canned in a pinch and that batch lost a certain specialness of homemade. It's worth it to go homemade, since you're already fussing with kolacy or buchty anyway.
Petra Kupská says
I couldn't agree with you more! However, I also take into account that poppy seeds are not as widely available around the world as they are in the Czech Republic. Furthermore, there is the issue of how to grind it.
Michelle says
What about added chocolate to the poppy? What would you say would be the amount to add to give it the perfect mixture of poppy and chocolate? Would you still add the jam and sugar?
Thank you
Cm says
Not on Oahu right now!!
Ruth Kraus says
lucky you! Unavailable in UK
Jean Luby says
You are absolutely right about being underrated. Here in Canada I buy it at the Bulk Barn in large quantity. The cashier at the time asked me what I was going to do with all the poppy seed. Unfortunately my problem is the grinding. I do use a spice grinder that works on maximum 4 TBS at a time. We use to have a proper Czech grinder used or grinding nuts and poppy see which made it much faster.
Dejan Igyidov says
I have good results in poppy seed grinding with a simple small electric coffee grinder. You should grind it only for the recipe you will make because poppy seeds tend to quickly spoil (go rancid) after grinding. Ground poppy seeds will spoil even in the freezer.
Kenneth says
This sounds great but I have a couple questions. Thank you.
What is the purpose of the milk and what does it do? Why can't we just use water?
What is the purpose of the jam?
Diana Chandler says
If I were to make a big batch of this.. what is your recommendation for storing leftovers? Fridge? Freezer? Canning?
Thanks!
Petra Kupská says
Ahoj Diana,
I usually only make the amount I use. Maybe it's because poppy seeds are widely available in the Czech Republic, both whole and ground. If you make a big batch of poppy seed filling, probably the easiest way to preserve it is to divide the chilled filling into smaller portions and freeze it. Hope it helps at least a bit!
Best wishes, Petra
Bonbon says
Why do you add jam? I've never heard of doing this. Wouldn't it take away the taste from the poppy seed?
Petra Kupská says
I add jam to the poppy seed filling to make it juicier, if I may say so. In the Czech Republic, we usually add plum jam (povidla), but I know that's not as easily available in the US.
jesk says
My Czech grandma occasionally used to put some cut-up prune plums for flavor, too. Or, also, often raisins.
Petra Kupská says
Yes, the Czechs often add raisins to poppy seed filling! Sometimes I add a little jam to make the filling juicier.
Sheila Keim says
Love these recipes!
Petra Kupská says
Thank you very much for your nice words, Sheila!
StillLostThanks says
I seen a bunch on amazon too but which ones are good, you sounded like you had some insight, what a waste of time.
Ulrike says
I order mine online from Nuts.com comes in a pound bag when I order seeds for rye breads and other grain breads . Usually get 2 and toss one in the freezer. Fresh products no matter what I order
Jody Gallup says
This sounds like a recipe like my Grandma used to make delicious kolaché. I will try this recipe.
Anicka Cooklikeczechs.com says
Thank you for your comment, Jody. Please, let me know how the recipe turned out afterwards!
Best of luck!
Anne P Strong says
My Czech Grandma always made the tied Kolache...little packages, she called them!! She also made an apricot filling and a prune filling both she cooked fresh fruit to make. Never got those recipes from her before she passed . Thank you for this recipe. I enjoy your site very much.
Petra Kupská says
Thank you, Anne, for your kind comment! You can try this recipe of mine for tied Kolache, hopefully they will taste close to the ones your grandmother used to make!
Sarah says
I ground 2 cups of poppy seeds and added 1 cup of milk, and the poppy seeds completely absorbed the milk. The recipe says to bring this to a boil, but when I stir it, there is no liquid in the bottom of the pot--it seems like it will just burn. What am I doing wrong here?
Petra | Cook Like Czechs says
Hi Sarah,
It sounds like the poppy seeds absorbed all the milk too quickly, which can happen if the seeds are finely ground and/or if the milk gets too hot. If the mixture is too thick and dry, you can add more milk, a little at a time, to loosen it up.
Suzanne RN says
This is an excellent recipe for fleshly made poppyseed filling! I made it sugar free and it tasted wonderful in my poppyseed strudel and solace!
Andrea says
Thank you so much for posting the Slovak poppy seed recipes. Would always have opekance and Kolache on Christmas Eve.
All the best.
G says
Thank you. When I was a child, my grandmother made both walnut and poppy seed loaves at Christmas, but only her walnut filling was passed down. I don't know if hers was like this or not, but I thoroughly enjoyed my first attempt at a poppy seed filling and will try again.
Petra Kupská says
I am glad that the walnut filling stayed in the family, and that poppy seed filling gave you a chance to try something new while still feeling connected to your grandmother’s baking. Wishing you many more happy experiments.
Ivana says
My mother used to add red currant jam (not available in the US) instead of prune butter; the sour note added freshness to the filling. The closest I come in the US is using organic seedless raspberry jam form a brand that uses less sugar than the more commercial brands. Note of caution: the seeds have to be fresh, otherwise they turn bitter! I get poppy seed from Penzeys and freeze the unused portion, unground. Left too long, however, even in the freezer, can turn them bitter. Re. the canned stuff, don't bother, it's full of sugar and starch, and I think the seeds are not ground. Happy baking!
Petra Kupská says
The red currant jam that tart note must balance the filling beautifully. Raspberry jam with less sugar sounds like a wonderful substitute when currants aren’t available. Thank you for the note about the poppy seeds. Once they turn bitter, there’s no saving the dish! The canned fillings don’t compare to freshly ground seeds, that is true. But if people don't have and access then this is probably the next best thing. Thank you for taking the time to share such helpful tips, this will benefit many readers. Happy baking to you as well!
Luanne says
My Dad was Bohemian, and through him we had a poppy seed grinder when I was growing up, and we raised our own seed. Then I moved away. I can get poppy seed from a bulk store, but I didn't have a grinder, and I didn't want to settle. Then I found a grinder on a garage sale! I grabbed it fast. The people holding the sale asked me if I knew what it was, and were surprised that I did. Now I have a grinder too. As for the recipe, we never added jam or zest. We just used ground seed, milk, and sugar, though we would fill kolache with this and fruit cooked separately.
Petra Kupská says
That’s amazing, you even found a grinder at a garage sale! It is a great find.
