Ingredients
Scale
- 4 large eggs, room temperature
- ¾ cup (150 g) granulated sugar
- 1 tsp vanilla extract
- ¾ cup (95 g) all-purpose flour
- 1 tsp baking powder
- ¼ tsp salt
- 2 tbsp milk, warm
- 2 cups (480 ml) whole milk
- ½ cup (100 g) granulated sugar
- 4 large egg yolks
- ¼ cup (30 g) cornstarch
- 2 tbsp unsalted butter
- 1 tsp vanilla extract
- 1 cup (240 ml) heavy cream
- 8 oz (225 g) semi-sweet chocolate, chopped
- 1 tbsp unsalted butter
- Chocolate shavings or powdered sugar (optional)
Instructions
- Make the Pastry Cream: In a saucepan, heat milk until steaming but not boiling. In a bowl, whisk egg yolks, sugar, and cornstarch until pale. Slowly pour hot milk into yolk mixture, whisking constantly. Return to saucepan and cook until thickened. Remove from heat, stir in butter and vanilla. Cover with plastic wrap touching the surface, chill completely.
- Make the Sponge Cake: Preheat oven to 350°F (175°C). Line a 10×15-inch jelly roll pan with parchment paper. Beat eggs and sugar until thick and pale (about 5 minutes). Mix in vanilla. Sift together flour, baking powder, and salt; fold into egg mixture gently. Stir in warm milk. Spread batter evenly into pan and bake for 10–12 minutes, until lightly golden and springy.
- Roll the Cake: While hot, turn cake out onto a clean kitchen towel dusted with powdered sugar. Peel off parchment, then roll cake up in the towel (short end first). Let cool completely.
- Fill the Cake: Unroll cooled cake, spread pastry cream evenly inside. Roll up tightly again.
- Make the Ganache: Heat cream until simmering. Pour over chopped chocolate. Stir until smooth, then add butter for shine.
- Assemble: Pour ganache over the rolled cake. Sprinkle with chocolate shavings or dust lightly with powdered sugar.
- Chill & Serve: Refrigerate for at least 1 hour before slicing for neat cuts.
Notes
- Ensure the eggs are at room temperature for better volume.
- Use a clean kitchen towel to prevent sticking when rolling the cake.
- Chilling the cake helps set the ganache and makes slicing easier.
