Some desserts instantly remind us of childhood flavors and simple homemade treats. Choco-Plasma cubes are one of those cakes that combine familiar ingredients into something incredibly satisfying. The gentle sweetness of plasma biscuits, the richness of chocolate, and the creamy filling come together to create a dessert that is both comforting and delicious.

Plasma biscuits are a well-known classic in many Balkan kitchens and are often used in homemade desserts. Their delicate texture and mild vanilla flavor pair beautifully with chocolate and creamy fillings. In many recipes they can even replace traditional biscuit bases, similar to those used in cheesecakes. In this cake, however, plasma biscuits are not just an ingredient — they are one of the highlights of the entire dessert.
This cake is a great option when you want a dessert that looks impressive but is actually simple to prepare. It works perfectly for birthdays, family gatherings, or casual get-togethers with friends. The filling requires no baking, which makes the preparation quick and practical. Once assembled and chilled, the cake becomes wonderfully soft and full of flavor.
If you enjoy desserts that balance chocolate richness with creamy textures, Choco-Plasma cubes are sure to become one of your favorites.
Ingredients
For the sponge layer
- 5 eggs
- 5 tablespoons sugar
- 1 packet vanilla sugar
- 100 ml oil
- 5 tablespoons flour
- 1 baking powder
- 3 tablespoons cocoa powder
- 5 tablespoons milk
Preparing the sponge
Whisk the eggs together with the sugar until the mixture becomes light and airy. Add vanilla sugar and oil, then mix again. Gradually incorporate the flour, baking powder, cocoa powder, and milk, stirring until the batter becomes smooth.
Pour the mixture into a prepared baking pan and bake in a preheated oven at 220°C for about 15 minutes.
Once the sponge is baked, slowly pour 200 ml of milk over it while it is still warm so it becomes extra moist.
Ingredients for the filling
- 400 ml sweet cream
- 300 g sour cream
- 400 g plasma biscuits
- 5 tablespoons powdered sugar
Preparing the filling
Whip the sweet cream together with the powdered sugar until thick. Add the crushed plasma biscuits and sour cream, then gently mix until everything is evenly combined.
Spread the prepared filling over the cooled sponge base.
Chocolate glaze
- 400 ml cooking cream
- 200 g chocolate
Heat the cream over low heat and add the chocolate. Stir until the chocolate melts completely and the glaze becomes smooth. Pour the warm glaze evenly over the cake.
Allow the cake to cool until the chocolate topping sets.
Serving
For the best texture and flavor, place the cake in the refrigerator for several hours before serving. Cut it into neat cubes and serve with coffee, tea, or juice.
Each bite offers a perfect balance of soft sponge, creamy filling, and rich chocolate topping — a simple dessert that always disappears quickly from the table.
