Description

Boston Cream Cake is a delightful dessert that combines a moist yellow cake with a rich pastry cream filling, all encased in a glossy chocolate ganache. Despite its name, it’s actually a cake, not a pie. This dessert is perfect for special occasions or a sweet treat any time.

Ingredients

For the Cake:

1¾ cups all-purpose flour
1½ teaspoons baking powder
¾ teaspoon salt
¾ cup unsalted butter, softened
1½ cups granulated sugar
4 large eggs
1 teaspoon vanilla extract
1 cup whole milk

For the Pastry Cream:

2 cups half-and-half
6 large egg yolks
2 cups granulated sugar
1¾ cups all-purpose flour
4 teaspoons vanilla extract

For the Chocolate Ganache:

½ cup heavy cream
2 tablespoons light corn syrup
4 ounces bittersweet chocolate, chopped

Instructions

Prepare the Cake:
- Preheat the 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 bowl, cream the softened butter and sugar until light and fluffy.
- Add the eggs one at a time, beating well after each addition. Stir in the vanilla extract.
- Gradually add the dry ingredients to the wet mixture, alternating with the milk, beginning and ending with the dry ingredients. Mix until just combined.
- Divide the batter evenly between the prepared pans and smooth the tops.
- Bake for 25–30 minutes, or until a toothpick inserted into the center comes out clean.
- Remove from the oven and let the cakes cool in the pans for 10 minutes. Then, transfer to a wire rack to cool completely.
Make the Pastry Cream:
- In a medium saucepan, heat the half-and-half over medium heat until it begins to simmer.
- In a separate bowl, whisk together the egg yolks, sugar, and flour until smooth.
- Gradually add about ½ cup of the hot half-and-half to the egg mixture, whisking constantly to temper the eggs.
- Pour the tempered egg mixture back into the saucepan with the remaining half-and-half. Cook over medium heat, whisking constantly, until the mixture thickens and comes to a boil.
- Remove from heat and stir in the vanilla extract.
- Transfer the pastry cream to a bowl, cover with plastic wrap, and refrigerate until chilled.
Prepare the Chocolate Ganache:
- In a small saucepan, heat the heavy cream and corn syrup over medium heat until it begins to simmer.
- Remove from heat and add the chopped chocolate. Let it sit for 2–3 minutes, then stir until smooth and glossy.
- Allow the ganache to cool slightly before using.

Assemble the Boston Cream Pie:
- Place one cake layer on a serving platter. Spread the chilled pastry cream evenly over the top.
- Place the second cake layer on top of the pastry cream.
- Pour the cooled chocolate ganache over the top, spreading it evenly to cover the entire cake.
- Refrigerate the assembled cake for at least 2 hours before serving to allow the flavors to meld and the ganache to set.
