Flour, baking powder, sugar, vanillin, eggs, butter mix and knead the dough.
You can do it by hand, but I do it with a mixer using special dough attachments.
You can already preheat the oven to 180°C.
If you get a crumb-like mass, then the oil is not soft enough. In this case, I pour hot water into the sink, put a pan in it and continue to make the dough. The oil will melt and the result will be a normal dough.
Next, in any form on baking paper, we begin to lay out and tamp the dough with our hands. The shape must be with edges, otherwise the filling may float away.
To prevent the dough from rising, lay baking paper on it. (Don't forget to poke with a fork!)
Bake the dough for 12 minutes in an oven preheated to 180°C.
Meanwhile, we make the filling: cottage cheese, sugar, vanillin, cream and blueberries. Mix everything gently with a whisk. Next, pour our filling into the already prepared dough. Bake 30 minutes. At t~ 180-200°C.
