Wuzetka - Polish Chocolate Cream Cake

If you love a dessert that balances rich cocoa with light-as-air cream, meet the Wuzetka — Warsaw’s most famous culinary icon.

Born in the late 1940s, this nostalgic pastry was named after a major post-war highway project (the W-Z Route) and quickly became a symbol of the city's rebirth and cafe culture.

It’s the ultimate balance of textures. Unlike heavy buttercream desserts, the fresh cream keeps it surprisingly light, while the bitter cocoa prevents it from being overly sweet.

It’s a bite of Polish history that pairs perfectly with a hot cup of black coffee.

Chocolate Ganache (Topping)

- 140 g dark chocolate (about 60%)

- 60 ml heavy cream (30%)

Additional

- 150 ml strong black tea, cooled

- 150g tart jam (black currant or plum)

Instructions

1. Make the Sponge Cake

- Preheat the oven to 170°C.

- In a large bowl, beat the eggs with sugar until the mixture becomes very light, fluffy, and thick.

- Sift in the cake flour, cocoa powder, and baking powder. 

- Gently fold everything together until smooth and fully combined.

- Pour the batter into a lined 25 × 16 cm pan.

- Bake for about 30 minutes, or until a toothpick inserted in the center comes out clean.

- Let the cake cool completely.

- Once cooled, slice the sponge cake horizontally into 2 layers.

2. Prepare the Cream

- Soak the gelatin in cold water and let it bloom for about 5–10 minutes.

- Heat gently until fully dissolved (do not boil).

- In a cold bowl, beat the heavy cream with powdered sugar until it reaches soft peaks.

- Mix a few tablespoons of whipped cream with the melted gelatin first to temper it.

- Gently fold the gelatin mixture back into the remaining whipped cream until smooth.

3. Assemble the Cake

- Place the first sponge layer back into the pan.

- Soak it evenly with half of the cooled black tea.

- Spread the jam evenly over the cake.

- Spread about 3/4 of the whipped cream filling over the sponge.

- Place the second sponge layer on top and gently press down.

- Soak the top layer with the remaining black tea.

- Refrigerate while preparing the ganache.

4. Make the Chocolate Ganache

- Heat the heavy cream until hot but not boiling.

- Add the chopped dark chocolate and let it sit for a minute.

- Stir until smooth and glossy.

- Pour the ganache over the top of the cake and spread evenly.

- Chill for about 30 minutes until the chocolate sets.

5. Decorate

- Use the remaining whipped cream to pipe rosettes on top of the cake.

- Chill for a few more hours before slicing.
