Ingredients
Scale
Sponge Cake
- 2 cups all-purpose flour (sifted)
- 1 cup granulated sugar
- 1 tbsp baking powder (fresh)
- 1 cup whole milk
- 1/2 cup unsalted butter
- 3 large eggs
Pastry Cream
- 1/2 cup granulated sugar
- 1/4 cup cornstarch
- 2 cups whole milk
- 4 large egg yolks
- 2 tbsp unsalted butter (optional)
- 1 tbsp vanilla extract
Ganache
- 1 cup heavy cream
- 8 oz semi-sweet chocolate
- 2 tbsp corn syrup (optional)
Instructions
- Pastry Cream Preparation: In a medium saucepan, whisk together sugar and cornstarch until combined. Heat the milk in a separate saucepan until just simmering. In a bowl, beat the egg yolks, then slowly whisk in the warm milk to temper the eggs. Combine this mixture with the sugar and cornstarch mixture in the saucepan and cook over medium heat, stirring constantly for 5-7 minutes until it thickens. Remove from heat, stir in butter and vanilla extract, strain the pastry cream into a bowl, and refrigerate until thoroughly cooled.
- Sponge Cake Preparation: Preheat the oven to 350°F (175°C). Grease and flour two 9-inch round cake pans. In a mixing bowl, sift together flour, baking powder, and sugar. Warm the milk and butter together in a saucepan and set aside. Beat eggs until light and fluffy, then gently fold in the dry ingredients followed by the warm milk and butter mixture. Divide the batter evenly between the prepared pans and bake for 25-30 minutes until the cakes are golden and spring back when touched. Let the cakes cool completely.
- Cake Assembly: Once cooled, level the sponge cakes by slicing off the domed tops to create flat layers. Place the first cake layer on a serving platter and spread half of the chilled pastry cream evenly over it. Place the second layer on top and loosely cover with plastic wrap. Refrigerate for at least 30 minutes to allow the filling to firm up.
- Ganache Preparation: Heat the heavy cream in a saucepan over medium heat until it just begins to simmer. Remove from heat and pour over the chopped semi-sweet chocolate, letting it sit for 5 minutes to melt. Stir gently until the ganache is smooth and glossy. Allow it to cool slightly to thicken at room temperature.
- Finish the Cake: Take the cake out of the refrigerator and carefully pour the ganache over the top, spreading with a spatula if needed to cover evenly. Return the cake to the refrigerator for another 30 minutes to let the ganache set before serving.
Notes
- The cake layers can be baked a day ahead and stored tightly wrapped at room temperature.
- Use room temperature ingredients for best results and smooth batter.
- For a dairy-free version, substitute almond milk for milk and coconut cream for heavy cream.
- Omitting butter in pastry cream yields a lighter cream, but butter adds richness and silkiness.
- Corn syrup in ganache helps maintain a shiny glaze but can be omitted.
