A tender hot‑milk sponge, soaked with fragrant coffee and layered with airy mascarpone cream, this cake brings together the softness of a classic sponge and the cozy charm of tiramisu. Each thin layer melts into the next, creating a light, balanced dessert that feels both simple and quietly indulgent.

Ingredients:

• sugar	200 g
• salt	a pinch
• butter	75 g
• flour	225 g
• baking powder	10 g
• milk	180 ml
• eggs	6 large
• vanilla sugar	7 g
• strong coffee (for soaking)	250 ml
• cognac (optional, for soaking)	50 ml
• heavy whipping cream (for the cream)	700 ml
• mascarpone cheese (for the cream)	450 g
• powdered sugar (for the cream)	180–200 g
• cocoa powder (for dusting)	to taste

HOT MILK SPONGE (All sponge ingredients should be at room temperature.)

1. Preheat the oven to 180°C (355°F).

2. In a bowl, sift together 225 g flour and 10 g baking powder. Whisk to combine.

3. In a mixing bowl, combine 6 eggs, 200 g sugar, 7 g vanilla sugar, and a pinch of salt. Beat until the mixture becomes very light, pale, and fluffy (about 10–12 minutes). A properly whipped mixture will hold a figure‑eight shape for a moment.

4. In a small saucepan, combine 180 ml milk and 75 g butter. Heat over medium, stirring constantly, until the mixture comes to a boil.

5. Add the flour–baking powder mixture to the whipped eggs in portions, folding gently but thoroughly from bottom to top with a spatula.

6. If the milk mixture has cooled, quickly bring it back to a boil. Very carefully pour the hot milk and butter along the side of the bowl into the batter. Fold gently until smooth.

7. Line the bottom of an 18 cm (7‑inch) round springform pan with parchment paper.

8. Pour the batter into the pan and spread it evenly.

9. Bake the sponge in the preheated oven for 40–45 minutes. Check doneness with a wooden skewer — it should come out completely dry.

10. Remove the sponge from the oven and let it rest in the pan for 10 minutes.

11. Run a thin knife along the sides of the pan, remove the sponge, and place it on a cooling rack to cool completely.

COFFEE SYRUP

12. Brew strong, unsweetened coffee. Let it cool to room temperature. Add cognac if using. The soaking syrup is ready.

MASCARPONE CREAM (Mascarpone and cream must be well chilled.)

13. Whip the heavy cream with 180–200 g powdered sugar until stiff peaks form, starting on low speed and gradually increasing.

14. Add the cold mascarpone in portions and mix on low speed until the cream becomes smooth and uniform.

ASSEMBLY

15. Slice the cooled sponge into thin layers using a cake wire or a long serrated bread knife. (At least 3 layers; I prefer very thin ones — I usually get 6–7.)

16. Spread a little cream on the cake board or serving plate to secure the bottom layer.

17. Place the first sponge layer on the board and press lightly so it doesn’t slide. Wrap with an acetate collar and secure with a cake ring. (You can assemble without them — just work carefully and wrap the cake tightly in plastic wrap afterward.)

18. Soak the sponge layer with the coffee syrup, covering the top and edges.

19. Transfer the cream to a piping bag fitted with a round tip (or simply snip off the end of the bag).

20. Pipe a layer of cream over the first sponge layer and smooth it with a spatula.

21. Place the next sponge layer on top, soak it, and add cream. Repeat with all layers. Spread cream over the top layer and dust with cocoa. Don’t forget to reserve a couple of spoonfuls of cream for decorating.

22. Let the cake set in the refrigerator for at least 4 hours. Place the reserved cream in a container and refrigerate as well.

23. Remove the ring and acetate, and decorate the cake with the remaining cream.

SERVING IDEAS:

- Fresh berries (raspberries or strawberries) for a bright, tart contrast to the creamy layers.

- Chocolate curls or shavings sprinkled over the top for a more festive look.
