Finnish Chocolate Curd Pie

I almost always choose the simplest cooking recipes (exceptions are holidays). To be honest, the recipe that begins with the words "cut six lemons into thin circles" is already perceived by me on weekdays without much enthusiasm.
But there are combinations of products that I can't resist. In this case, it's baked cottage cheese and chocolate. There are many recipes that combine both, but I chose this recipe of Finnish cuisine, in which the most difficult thing we have to do is to heat chocolate. Actually, fun, familiar from childhood. We'll manage. Food, as they say, requires sacrifices.
Chocolate-curd pie, in fact, a curd sponge cake, in appearance resembling a familiar zebra. But it is the cottage cheese that makes it softer and gives it a taste that is simply impossible to resist.
First you need to melt the chocolate together with the butter in a water bath.

Beat 4 eggs and 300 g of sugar with a mixer, add salt, flour and baking powder. It is advisable to mix the flour with baking powder first, and then introduce it into the mass.
Mix all this with the cooled chocolate-butter mass.
Leave the chocolate dough for now and take up the filling (or light dough).
Whisk together the cottage cheese, 100 g of sugar, 2 eggs and vanilla.
Is also ready.

Now we have masses of two colors.
There is a recommendation to line the form with parchment paper. I'll keep it, just in case, but I'll take a non-stick mold instead.
Now pour the chocolate mass into the mold, but not all of it. Align.
You can show imagination. If the shape is deep, pour a light mass from above into the center, and several dark islands on it. Or in a wide form, we carefully pour islands of light mass, and on them there are also islands of dark. With a wooden stick (toothpicks, skewers), we draw on the surface, imitating a marble pattern, or we will give the dark islands on a light background the shape of starfish.
We send all this beauty to the oven, heated to 180 degrees, until fully cooked.
