Ořechy, these cookies, baked in the shape of walnuts and filled with delicious buttercream, are among the most beloved Czech Christmas treats. Czechs make them every year during the holiday season.
If you have whole walnuts, grind them first. Place the ground walnuts in a bowl, then add the flour, powdered sugar, cocoa powder, and chopped butter.
Knead the mixture into a smooth dough, wrap it in plastic wrap, and let it rest in the fridge for at least two hours.
Meanwhile, prepare the molds by greasing each one with a bit of butter or other fat and dusting them with flour. Tap out any excess flour.
Take the nut dough out of the fridge and let it sit on the kitchen counter for about 15 minutes. Scoop out equally sized pieces, pressing each into the prepared mold. Press the dough in the center slightly with your thumb to create a well. This is where the filling comes.
Place the filled molds on a baking sheet and bake them in an oven preheated to 350 °F for 10 minutes.
Allow the baked cookies to cool almost completely, then gently tap each mold upside down on the work surface; the cookie should fall out easily.
Prepare the buttercream filling by beating the softened butter with the powdered sugar until smooth. Then, add the finely ground nuts and rum, mixing until well combined.
Fill the cookies with the buttercream using a round knife or two teaspoons. Once filled, cover the buttercream with another cookie to form a sandwich.
Notes
The basic recipe makes around 35 Orechy cookies.
After baking, these nut cookies are crispy, but they start to soften after a few days.
