Prepare the necessary ingredients.
Wash the poppy seeds and cover with milk. Cook the poppy-milk mixture over low heat for 1 hour, stirring occasionally to prevent burning.
150 g poppy seeds, 150 ml milk
While the poppy seeds are cooking, prepare the shortcrust pastry. Cream the soft butter with sugar, salt, and yolks.
100 g sugar, 140 g butter, 1 pinch salt, 3 pcs egg
Mix the flour with baking powder and add to the sugar-butter mixture. Mix everything until you get a homogeneous, elastic mass.
300 g flour, 1 tsp baking powder
Divide the ready dough into two unequal parts in a 2:3 ratio, wrap in plastic wrap and refrigerate for 40 minutes.
While the dough is cooling, finish preparing the filling. Grind the cooked poppy seeds with a blender and let the mass cool down properly. Then add sugar, vanilla, and softened butter.
100 g sugar, 1 tsp vanilla extract, 30 g butter
Whip the cooled egg whites into a firm foam (to stiff peaks) using a mixer.
3 pcs egg
Gently fold the whipped whites into the poppy seed mass with a spatula, making it more tender and voluminous. The filling is ready.
Take the larger part of the dough out of the refrigerator, roll it out to a thickness of 0.5–0.7 cm. Then carefully place the dough in the form, forming small edges, prick with a fork and bake in the oven preheated to 180˚C for 10–15 minutes.
After the dough has set, remove the form from the oven and fill with the poppy seed filling to the edges.
Take the smaller part of the dough out of the refrigerator and grate it on a coarse grater over the filling so as to cover the entire surface. Send the baking back to the oven for another 20–25 minutes.
The finished cake should be removed from the form and completely cooled.
Enjoy your meal!
