In a deep bowl put the products-eggs, sour cream, fermented baked milk, vanilla, 1/2 Cup sugar, rum or brandy. Beat with mixer.
Add flour mixed with baking powder and beat again.
Halva break into pieces, add to the dough and mix with a spoon.
Spread the dough on oiled molds to 1/2 the height of the mold and bake in a preheated oven for 40-45 minutes at a temperature of 180 degrees (baking time depends on the size of the mold). Check the readiness with a toothpick - it may be slightly in the specks of dough or halva, but not in the raw dough.
From this number of test I have have have a cupcake diameter of 20cm and 6 cupcakes-hearts.
Cool the cupcakes in the forms and turn over on the dish. Here is such a beauty I have.
Cook the glaze: melt the butter, add 1/2 Cup sugar, orange juice, cook for 3-4 minutes. Hot glaze to pour over the cupcakes.
