Ingredients

Here’s what you’ll need to create this irresistible Boston Cream Pie:

For the Cake:

  • All-Purpose Flour: This is the base of the cake, giving it structure and texture.
  • Baking Powder: Helps the cake rise to a light and fluffy texture.
  • Sugar: Adds sweetness to balance the rich cream and chocolate layers.
  • Eggs: Essential for structure and moisture.
  • Butter: A key player in making the cake soft and tender.
  • Milk: Adds moisture to the batter and helps create the perfect cake texture.
  • Vanilla Extract: For that warm, aromatic sweetness that pairs so well with the pastry cream.

For the Pastry Cream:

  • Milk: A creamy base for the filling.
  • Egg Yolks: Give the pastry cream its rich, custard-like texture.
  • Sugar: For sweetness and to balance out the richness.
  • Cornstarch: Helps thicken the custard to the perfect consistency.
  • Vanilla Extract: Adds a beautiful depth of flavor to the cream.
  • Butter: For extra creaminess and richness.

For the Ganache:

  • Heavy Cream: Creates that smooth, luscious ganache texture.
  • Semi-Sweet Chocolate: The star of the ganache, adding that rich, chocolaty flavor that ties everything together.

Instructions

Let’s walk through the steps to create this dessert masterpiece:

Bake the Cake

Preheat your oven to 350°F (175°C) and grease and flour two 9-inch round cake pans. In a bowl, whisk together the flour, baking powder, and sugar. In a separate bowl, whisk the eggs, melted butter, milk, and vanilla. Gradually add the wet ingredients to the dry ingredients and mix until smooth. Divide the batter evenly between the two pans and bake for 25-30 minutes, or until a toothpick comes out clean. Allow the cakes to cool in the pans for 10 minutes before transferring them to a wire rack to cool completely.

Make the Pastry Cream

While the cake is baking, start on the pastry cream. In a saucepan, heat the milk over medium heat until it’s just about to simmer. In a separate bowl, whisk together the egg yolks, sugar, and cornstarch until smooth. Gradually pour the hot milk into the egg mixture, whisking constantly. Return the mixture to the saucepan and cook over medium heat, whisking constantly, until it thickens (about 2-3 minutes). Once thickened, remove from heat and stir in the vanilla extract and butter. Pour the pastry cream into a bowl, cover with plastic wrap (press the wrap directly onto the cream to prevent a skin from forming), and refrigerate until chilled.

Prepare the Ganache

In a small saucepan, heat the heavy cream over medium heat until it just starts to simmer. Remove from heat and add the chopped semi-sweet chocolate. Let it sit for a minute, then stir until smooth and glossy. Allow the ganache to cool slightly before using.

Assemble the Cake

Once your cakes have cooled, place one layer on a serving plate. Spread the chilled pastry cream evenly over the top of the cake layer. Carefully place the second cake layer on top. Pour the ganache over the top, allowing it to drip down the sides for that signature Boston Cream Pie look.

Chill and Serve

Allow the cake to chill in the fridge for at least an hour to let the layers set and for the ganache to firm up. Slice, serve, and enjoy the creamy, chocolatey goodness!

How to Serve Boston Cream Pie

Boston Cream Pie is a stunning dessert all on its own, but here are a few ways you can serve it for extra flair:

Classic

Serve it chilled, sliced into wedges, and enjoy with a cup of coffee or tea for a classic, indulgent treat.

With Fresh Berries

Top with fresh berries like strawberries or raspberries for a pop of color and a hint of tartness to balance the richness.

A la Mode

Serve a slice with a scoop of vanilla ice cream on the side. The cold ice cream pairs perfectly with the warm ganache and creamy filling.

With Whipped Cream

Add a dollop of freshly whipped cream on top for an extra touch of elegance and a bit of lightness to the dessert.

Additional Tips

Make Ahead

This cake actually gets better with time! You can make it the day before, which gives the flavors time to meld together. Just keep it refrigerated and bring it to room temperature before serving for the best flavor and texture.

Customization

If you prefer a different flavor, you can switch up the ganache for a white chocolate version, or even add a hint of coffee to the pastry cream for a mocha twist.

Storage

Store leftovers in the fridge for up to 3 days. The cake will still be delicious, but I doubt you’ll have any leftovers!

Keep the Layers Even

To ensure the cake layers are even, you can trim the tops of the cakes slightly before layering them. This helps create a more even base for the pastry cream.

FAQ Section

Q1: Can I make this cake in advance?

A1: Yes! You can make the cake, pastry cream, and ganache a day in advance. Just assemble it the day you plan to serve it.

Q2: Can I use a different type of chocolate for the ganache?

A2: Absolutely! Dark chocolate, milk chocolate, or even white chocolate would work. Just keep in mind the flavor will change depending on your choice.

Q3: Can I use store-bought cake mix for this recipe?

A3: While homemade cake is always best for this recipe, you can substitute with a store-bought cake mix for a quicker version. Just be sure to follow the instructions on the box.

Q4: Can I make the pastry cream without egg yolks?

A4: You can try using a substitute like cornstarch or a store-bought custard mix, but it won’t have quite the same rich, custardy texture that egg yolks provide.

Q5: How do I store leftover Boston Cream Pie?

A5: Store any leftovers in an airtight container in the refrigerator for up to 3 days. Make sure to cover the top so the ganache doesn’t get damaged.

Q6: Can I freeze this cake?

A6: It’s not recommended to freeze the finished Boston Cream Pie as the layers may not hold up well. However, you can freeze the individual components (cake layers, pastry cream, and ganache) and assemble it when you’re ready to serve.

Q7: What can I use if I don’t have cornstarch for the pastry cream?

A7: You can substitute cornstarch with an equal amount of all-purpose flour, but the texture may be slightly different.

Q8: Can I use whipped cream instead of ganache for the topping?

A8: While traditional Boston Cream Pie uses ganache, you can certainly top it with whipped cream if you prefer a lighter option.

Q9: How can I make this cake more chocolatey?

A9: You can add cocoa powder to the cake batter for a deeper chocolate flavor or make a thicker ganache layer.

Q10: Can I use a different filling for the cake?

A10: Yes! While the pastry cream is traditional, you could swap it for a rich custard or even a flavored mousse for a different take on this classic.

Conclusion

Boston Cream Pie is the perfect blend of elegance and comfort. With its rich layers of sponge cake, creamy custard filling, and smooth chocolate ganache, it’s a dessert that’ll always impress.

  • 1 cup all-purpose flour
  • 1 tsp baking powder
  • ¼ tsp salt
  • 2 large eggs
  • 1 cup granulated sugar
  • 1 tsp vanilla extract
  • ½ cup whole milk

For the Custard Filling:

  • 1 ½ cups whole milk
  • 3 large egg yolks
  • ⅓ cup granulated sugar
  • 1 ½ tbsp cornstarch
  • 1 tsp vanilla extract
  • 2 tbsp unsalted butter

For the Chocolate Ganache:

  • ½ cup heavy cream
  • 4 oz semi-sweet chocolate, chopped
  • 1 tbsp unsalted butter

Instructions

  1. Make the Cake
    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 another bowl, beat the eggs and sugar until pale and fluffy. Add the vanilla extract, milk, and melted butter, and mix until combined. Gradually add the dry ingredients and stir until just incorporated.

  2. Bake the Cake
    Divide the batter evenly between the two prepared pans. Bake for 25-30 minutes or until a toothpick inserted in the center comes out clean. Let the cakes cool in the pans for 10 minutes, then turn them out onto a wire rack to cool completely.

  3. Make the Custard Filling
    In a saucepan, combine the milk, egg yolks, sugar, and cornstarch. Cook over medium heat, whisking constantly until the mixture thickens and comes to a boil. Remove from heat, then stir in the vanilla extract and butter. Let the custard cool slightly before using.

  4. Assemble the Cake
    Once the cakes are completely cooled, place one layer on a serving platter. Spread the custard filling evenly over the top. Place the second cake layer on top of the custard.

  5. Make the Chocolate Ganache
    Heat the heavy cream in a small saucepan over medium heat until it just begins to simmer. Pour the hot cream over the chopped chocolate and let it sit for 2-3 minutes. Stir until smooth, then mix in the butter until glossy.

  6. Top the Cake
    Pour the chocolate ganache over the top of the cake, letting it drip down the sides. Allow the ganache to set for about 30 minutes before slicing and serving.

Notes

  • The custard filling can be made ahead and refrigerated for a few hours. Just be sure to cover it with plastic wrap to prevent a skin from forming.
  • If you prefer a lighter cake, you can use a sponge cake or angel food cake instead of a traditional butter-based cake.
  • For a more decadent finish, top the cake with whipped cream before serving.
