Gluten-free chocolate-banana cake

1. Beat the eggs with sugar until foamy. Lightly mix the cake mix with a spatula and pour the dough into the silicone mold. Bake in a heated oven at 180°C for 20 minutes.
2. Mix the custard powder in 100 ml of milk and pour it into the remaining condensed milk with chocolate. Let's cook a thick porridge. Allow to cool, stirring occasionally, and stir in the sour cream.
3. Cut the dough in half with a sponge cutter. Spread a thin layer of the filling, place sliced bananas on the wheels, spread a larger layer of the filling, cover with the second part of the dough and spread a thin layer of the filling again.
4. Prepare the whipped cream according to the instructions on the Whipped Delight package. We can sweeten to taste and spread a thick layer of whipped cream on top of the cake. Let it harden until the next day. Decorate with chocolate, candies or fruit.

A good tip:
If we don't have a cookie cutter, we can use dental floss.
