Boston Cream Pie Pound Cake – a luscious, smooth vanilla pastry cream layered between tender cake slices and finished with a rich chocolate ganache. This dessert delivers both creamy vanilla and fudgy chocolate in every bite, a perfect balance of textures and flavors.
Boston Cream Pie Pound Cake
This recipe offers both vanilla and chocolate in one irresistible dessert. Despite the name, Boston Cream “Pie” is traditionally a cake: a vanilla cake filled with pastry cream and topped with a silky chocolate glaze. Inspired by classic versions and modern cupcake adaptations, this recipe reimagines the flavor profile in a loaf-style pound cake.
Traditionally served as round sponge or yellow butter cake, the Boston Cream flavor has made its way into cupcakes and bite-sized treats. Here it’s presented as a pound cake for a comforting, sliceable dessert that’s ideal for gatherings and holidays.
My Favorite Pound Cake Recipe
After a long break from making pound cake, inspiration struck during the holiday baking season. Popular recipes often bring readers back to classic pound cakes—like chocolate with ganache and cranberry-studded holiday loaves—so I wanted to create a version that combined a buttery vanilla crumb with a decadent chocolate topping and a smooth pastry cream center. That craving led to this Boston Cream Pie Pound Cake.
Best Vanilla–Chocolate Dessert with Ganache
I didn’t want to choose between vanilla and chocolate—I wanted both. The goal was a light, moist, tender vanilla pound cake with a fine crumb, a thick layer of pastry cream in the middle, and a generous, fudgy chocolate ganache on top. The contrast between the buttery cake, silky custard, and glossy ganache makes each slice memorable.
The combination of creamy vanilla pastry cream sandwiched between two cake layers and finished with a rich chocolate ganache is a winning match. This Boston Cream Pie Pound Cake satisfies both vanilla and chocolate lovers and makes an excellent dessert choice for Thanksgiving, Christmas, or any special occasion.

Ingredients
For Pastry Cream:
- 3 egg yolks
- 7 tablespoons granulated sugar
- ¼ teaspoon salt
- 1 ½ teaspoons vanilla extract
- 2 tablespoons cornstarch
- 2 tablespoons unsalted butter, softened
- 1 1/3 cups heavy cream
For Cake:
- 1 ½ cups sifted all-purpose flour
- 1 ½ teaspoons baking powder
- ½ teaspoon salt
- 3 eggs
- 1 cup granulated sugar
- 6 tablespoons unsalted butter
- ½ cup milk
- 1 teaspoon vanilla extract
Chocolate Ganache:
- 6 oz semi-sweet baking chocolate, finely chopped
- ¾ cup heavy cream
Instructions
To make the pastry cream:
- Whisk together egg yolks, sugar, and salt. Add cornstarch and whisk until the mixture becomes pale yellow and thick.
- In a medium saucepan, heat 1 1/3 cups heavy cream, then add the egg mixture and stir to combine. Cook over medium heat, whisking constantly, until it thickens to a pudding-like consistency.
- Remove from heat, stir in butter and vanilla until smooth. Transfer to a bowl and press plastic wrap directly onto the surface to prevent a skin from forming. Refrigerate at least 2 hours to set.
To make the cake:
- Preheat oven to 350°F. Butter and flour a 9 x 5 x 3-inch loaf pan (or line it with parchment, leaving an overhang to lift the cake).
- In a small saucepan over low heat, combine milk and butter and bring just to a boil, then set aside.
- Whisk together flour, baking powder, and salt; set aside.
- Beat eggs and sugar on high speed until thickened and pale, about 4–5 minutes. Fold in the dry ingredients with a rubber spatula until combined.
- With the mixer on low, slowly pour the hot milk into the batter and mix until smooth. Stir in vanilla.
- Spread the batter into the prepared loaf pan, smooth the top, and bake. After 20 minutes, rotate the pan and tent with foil if browning too quickly. Bake until golden and a toothpick inserted into the center comes out clean, about 35–45 minutes (ovens vary).
- Cool in the pan for 10 minutes, then transfer to a rack to cool completely. Using a serrated knife, slice the cooled loaf horizontally. Place the bottom half on a serving plate, spread the pastry cream leaving a ½-inch border, then gently place the top half of the cake.
Chocolate ganache:
- Melt the finely chopped chocolate over a double boiler, then remove from heat and add the warmed heavy cream. Stir until smooth. If the ganache is too runny, let it cool at room temperature until it thickens slightly.
- Spoon about half the ganache onto the cake and spread to the edges. Spoon the remaining ganache and smooth the top with a spatula. Allow the ganache to set before slicing.
