I have been trying different variations for the base of cheese cakes for a long time and this is probably the best solution so far.
Grind rye flakes on the base and blend together with the banana.
Put the mass in shape and compress.
Mix the filling ingredients - blend, pour on the base and place in an oven preheated to 180 degrees for ~ 35 -40 minutes (see after your stove). Remove and cool slightly.
Gelatin with 50 g of water and allow to swell. Put 150 g of berries in a pot with 100 g of water, sweetener and bring to a boil.
Stir the swollen gelatin into the boiled berries and dissolve with stirring.
Pour the curd over the curd. Put in the refrigerator to freeze.
