Step-by-Step Guide to Making Boston Cream Cake
Bake the Cake Layers
- Preheat your oven to 350°F (175°C). Grease and flour two 9-inch round cake pans.
- In a medium bowl, whisk together the flour, baking powder, and salt.
- In a large mixing bowl, beat the softened butter and sugar until light and fluffy. Add the eggs one at a time, then stir in the vanilla extract.
- Gradually add the dry ingredients to the butter mixture, alternating with the milk, and mix until smooth.
- Divide the batter evenly between the prepared pans and bake for 25-30 minutes, or until a toothpick inserted into the center comes out clean.
- Let the cakes cool in the pans for 10 minutes, then transfer to a wire rack to cool completely.
Prepare the Vanilla Custard
- In a medium saucepan, heat the milk over medium heat until warm (do not boil).
- In a bowl, whisk together the sugar, cornstarch, and egg yolks until smooth. Gradually add the warm milk, whisking constantly.
- Return the mixture to the saucepan and cook over medium heat, stirring constantly, until it thickens (about 5-7 minutes).
- Remove from heat and stir in the vanilla extract and butter until smooth. Cover with plastic wrap directly on the surface and refrigerate until completely cool.
Make the Chocolate Ganache
- Heat the heavy cream in a saucepan over medium heat until it just begins to simmer.
- Pour the hot cream over the chopped chocolate in a bowl and let sit for 1-2 minutes. Stir until smooth and glossy. Let the ganache cool slightly to thicken.
Assemble the Cake
- Place one cake layer on a serving plate. Spread the vanilla custard evenly over the top.
- Place the second cake layer on top and press gently to set.
- Pour the chocolate ganache over the top of the cake, allowing it to drip down the sides for a dramatic effect. Smooth the ganache with a spatula if needed.
Chill and Serve
- Refrigerate the assembled cake for at least 1 hour to allow the custard and ganache to set.
- Slice and serve chilled or at room temperature.
