Beat eggs and sugar with a mixer until firm, white foam. You can add baking soda (quench with vinegar or lemon juice).
Sift flour.
Add flour 1 tbsp, gently stirring the dough from bottom to top.
The dough is ready.
Grease the mold with oil. Pour the dough into a mold.
Place the dish in the oven on the middle shelf and bake until golden brown. Approximately 25-30 minutes. You can check the readiness – pierce the cake with a match, if it is dry, then the biscuit is ready.
Cool the cake, remove it from the mold. Cut in half with a knife or thread.
Stir the cottage cheese well with sugar and vanilla. (If the cottage cheese is dry, I recommend adding cream).
Put the curd filling on half of the crust. (You can add raisins, dried apricots, or prunes to the curd.)
Cover the filling with the second part of the crust.
Melt the pieces of chocolate in a water bath or on the smallest heat in a heavy-bottomed saucepan or skillet.
