Homemade Sponge Cake Roll with Cream and Fruit

Whip the eggs with the sugar until fluffy.

Add the milk and vegetable oil, then mix well.

Fold in the flour, baking powder, and vanilla, and mix into a smooth batter without lumps (the consistency should be like slightly runny sour cream).

Preheat your toaster, waffle maker, or grill, pour in a portion of the batter, and bake for a few minutes until done. Bake several layers by dividing the batter into 3–4 portions.

Trim the edges of the finished layers.

Whip the sour cream until stiff peaks form, gently fold in the condensed milk, and whip a bit more until smooth.

Spread the cream over a cake layer, top with sliced strawberries and bananas, add chocolate chips if desired, and roll everything up.
