I had 2 chocolate mini cheesecake in white frosting and one cheese stuffed with wild berries (jam) in chocolate glaze. Therefore, variations can be different.

Whisk three eggs with a mixer, add sugar, continue whisking to a froth. Melt the butter in the microwave and cooled a bit, add in the egg mixture. Then add sour cream, sifted flour and baking powder and whisk. Cheese finely cut, put in the dough and stir. Spread the batter into the pan or molds, and put in a preheated 200 degree oven for 35 minutes. Optional: cheese can not be cut, and put the whole between layers of dough. The taste is very unusual: cheese-chocolate-f rockowy.
