Learn how to make homemade poppy seed pastry filling for kolache, kolacky cookies, or buchty buns! These all are Czech pastries that traditionally call for poppy seeds. Let's dive into the recipe!
Czechs are the world's largest producers of poppies, so it is not surprising that poppyseeds have become a staple of Czech cuisine. The Czech name for the filling made with poppyseed is "makova napln".
The poppy seed filling is based on ground poppy seeds cooked in milk. It is sweetened with sugar and flavored with various ingredients. Here are some of them: spicy jam, freshly grated lemon zest, spiced rum, or perhaps crushed cloves.
MY TIP: Try this poppy seed roll (it tastes fantastic!)
➜ How to grind poppy seeds
In the Czech Republic, we buy blue poppies either whole or already ground.
If you are based in the US, you can get poppies in European deli stores (Polish, German). The downside is that you can only get whole poppy seeds, which you need to grind before making the filling.
The first way to grind poppy seeds is with a special manual poppy seed grinder. It’s available on Amazon in the US if you want one (I saw a few when I did some quick research).
The other method is to use a clean coffee grinder and grind the poppyseed in small batches.
➜ Ingredients
To make poppy seed filling from scratch, you’ll need:
- Poppyseed, ground in a mill or coffee grinder
- Whole milk, avoid using low-fat milk because there is no further fat added in this filling, and this is not a low-calorie recipe 🙂
- Granulated sugar
- Jam, the best variant is prune jam (Czech favorite); however, grab any solid jam you’ll find in your pantry
- Lemon zest, freshly ground

STEP 1: In a pot with a thick bottom, combine ground poppyseed and milk.
STEP 2: Bring to a boil over medium heat. Stir occasionally to prevent milk from burning. Add sugar, jam, and lemon zest.
STEP 3: Lower the heat and cook until the sugar dissolves and poppy seeds soften; it takes about 10 minutes. Don’t forget stirring.
STEP 4: When finished, transfer the poppy seed filling to a bowl, set it aside, and allow it to cool down completely:
Important: This poppy seed filling thickens while cooling down. Make sure it’s cold before using it.
➜ Cook’s Tips
- If the filling is too thin, add a few biscuit crumbles and stir.
- If the filling is too thick, add a spoon or two milk.
- Let the filling cool down before use!

FAQs
A simple way to ground poppyseed is by using a special mill. It’s a mainstay in Czech kitchens; try to find one from Tescoma (Czech brand). Another method is to grind poppy seeds in a clean coffee grinder.
Add some vanilla, crushed cloves (spice), rum-soaked raisins, or a tablespoon of spiced rum to the cooled filling for more flavor.

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.

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!

FYI, canned poppyseed filling is available in grocery stores. Is on the baking isle with pie filling.

If I were to make a big batch of this.. what is your recommendation for storing leftovers? Fridge? Freezer? Canning?
Thanks!

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
