Ingredients for the boston cream cake recipe
To make a traditional Boston cream cake, you’ll need the following:
Cake Layers:
- 2 1/2 cups all-purpose flour
- 2 1/2 tsp baking powder
- 1/2 tsp salt
- 1 cup unsalted butter, softened
- 2 cups granulated sugar
- 4 large eggs
- 2 tsp vanilla extract
- 1 cup whole milk
Custard Filling:
- 2 cups whole milk
- 1/2 cup granulated sugar
- 4 large egg yolks
- 1/4 cup cornstarch
- 2 tbsp unsalted butter
- 1 tsp vanilla extract
Chocolate Ganache:
- 1 cup heavy cream
- 8 oz semi-sweet chocolate, finely chopped
Step-by-Step Instructions for the boston cream cake recipe
1: Prepare the Cake Layers
- Preheat the Oven: Preheat your oven to 350°F (175°C). Grease and flour two 9-inch round cake pans, or line them with parchment paper.
- Mix the Dry Ingredients: In a medium bowl, sift together the flour, baking powder, and salt.
- Cream Butter and Sugar: In a large bowl, use an electric mixer to cream the butter and sugar until light and fluffy, about 3-4 minutes.
- Add Eggs and Vanilla: Beat in the eggs, one at a time, followed by the vanilla extract.
- Combine Wet and Dry Ingredients: Gradually add the dry ingredients to the butter mixture, alternating with milk, starting and ending with the dry ingredients. Mix just until combined.
- Bake the Cakes: Divide the batter evenly between the prepared pans. 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.
2: Make the Custard Filling
- Heat the Milk: In a medium saucepan, heat the milk over medium heat until it begins to steam. Do not let it boil.
- Whisk the Egg Mixture: In a separate bowl, whisk together the sugar, egg yolks, and cornstarch until smooth.
- Temper the Eggs: Slowly pour a small amount of the hot milk into the egg mixture, whisking constantly to prevent curdling. Gradually add the tempered egg mixture back into the saucepan with the remaining milk.
- Cook the Custard: Cook the mixture over medium heat, whisking constantly, until it thickens and begins to bubble.
- Add Butter and Vanilla: Remove the custard from the heat and stir in the butter and vanilla extract. Pour the custard into a bowl, cover with plastic wrap (pressing it directly onto the surface), and refrigerate until fully cooled.
3: Prepare the Chocolate Ganache
- Heat the Cream: In a small saucepan, heat the heavy cream over medium heat until it just begins to simmer.
- Melt the Chocolate: Place the chopped chocolate in a heatproof bowl. Pour the hot cream over the chocolate and let it sit for 5 minutes.
- Whisk Until Smooth: Stir the mixture until the chocolate is fully melted and the ganache is smooth. Let it cool slightly before using.
4: Assemble the Cake
- Layer the Cake: Place one cake layer on a serving plate. Spread the chilled custard evenly over the top. Place the second cake layer on top, pressing gently to adhere.
- Add the Ganache: Pour the chocolate ganache over the top of the cake, allowing it to drip down the sides. Use a spatula to spread it evenly, if needed.
- Chill the Cake: Refrigerate the cake for at least 1 hour to allow the layers to set before slicing.
Tips for a Perfect boston cream cake recipe
- Don’t Overmix the Batter: Overmixing can result in a dense cake. Mix just until the ingredients are combined.
- Chill the Custard: Ensure the custard is fully chilled before assembling the cake to prevent it from oozing out.
- Use Good-Quality Chocolate: The ganache is a key component of the cake, so opt for high-quality chocolate for the best flavor.
- Slice with a Hot Knife: For clean slices, dip your knife in hot water, wipe it dry, and cut the cake. Repeat for each slice.
