How to Make Boston Cream Pie Recipe
Step 1: Prepare the Pastry Cream
The heart of this Boston Cream Pie Recipe is its luscious pastry cream. Start by whisking sugar and cornstarch in a saucepan to ensure no lumps. Then blend milk and egg yolks separately before slowly combining, cooking gently while stirring until the mixture thickens. This silky custard is then enriched with butter and vanilla, strained for the smoothest texture, and chilled to set—giving you that luscious cream layer everyone loves.
Step 2: Bake the Sponge Cake
Next comes the backbone of the dessert: a light sponge cake. Preheat your oven, prepare your pans, and sift together your dry ingredients for an even rise. Warm your butter and milk to meld into the batter effortlessly. Then, beat eggs and sugar to fluffy perfection before folding in flour and the warm mixture. Baking carefully ensures a tender crumb that supports but doesn’t overpower the filling.
Step 3: Assemble the Cake
Once your pastry cream is chilled and cakes are cool, it’s time for assembly! Level your layers if needed for even stacking, then spread or pipe your creamy custard generously between the sponge layers. Top with the second cake and gently press to set, then refrigerate while making the final touch—the ganache.
Step 4: Make the Chocolate Ganache
Creating the ganache is such a rewarding step in this Boston Cream Pie Recipe. Simply heat heavy cream and pour it over chopped chocolate (and optional corn syrup for shine), letting it soften before stirring until glossy and smooth. Allow it to cool until thick yet pourable, ready to coat your cake with a beautiful chocolate finish that’s as stunning as it is delicious.
Step 5: Finish the Cake
Pour the ganache over the chilled cake, spreading it evenly to cover the top with a silky layer of chocolate. A final chill lets everything set nicely, making slicing clean and presentation flawless. After a couple of hours in the fridge, your Boston Cream Pie is ready to dazzle your taste buds and your guests.
How to Serve Boston Cream Pie Recipe
Garnishes
To elevate this classic, consider adding fresh berries or a dusting of powdered sugar around the edges. A few mint leaves provide a pop of color and freshness that contrasts beautifully with the rich chocolate glaze and creamy filling.
Side Dishes
Serve slices alongside freshly brewed coffee or black tea for an ideal café-style pairing. A scoop of vanilla ice cream can also add extra creaminess if you want to indulge even more.
Creative Ways to Present
Try turning your Boston Cream Pie into individual mini cakes using ramekins or cake rings, layering custard and sponge with the ganache on top for personal-sized decadence. Alternatively, bake in cupcake tins and fill with pastry cream after cooling—a playful twist on tradition that’s perfect for parties.
Make Ahead and Storage
Storing Leftovers
This dessert keeps beautifully in the fridge for up to 3 days when covered tightly. The flavors actually meld over time, making slices even more delicious the next day.
Freezing
If you want to freeze your Boston Cream Pie Recipe, freeze individual slices wrapped well in plastic and foil for up to one month. Thaw overnight in the fridge to maintain texture and flavor as much as possible.
Reheating
Since this is a creamy, chilled dessert, avoid reheating. Instead, serve straight from the fridge or allow it to sit at room temperature for 10-15 minutes for the best chocolate and custard melt-in-your-mouth experience.
FAQs
Is Boston Cream Pie really a pie or a cake?
Despite its name, Boston Cream Pie is actually a cake. Historically, the term “pie” was used more loosely to describe baked goods, but today it refers to this delightful layered sponge cake with custard and chocolate.
Can I make the pastry cream ahead of time?
Yes! Making pastry cream ahead is encouraged—it needs at least 2 hours chilling to set properly. You can even prepare it the day before, which makes assembly quicker and easier.
What type of chocolate works best for ganache?
Semi-sweet chocolate is typically used because it balances sweetness with a rich chocolate flavor, but feel free to use bittersweet or milk chocolate depending on your taste preferences.
Why do I need to strain the pastry cream?
Straining removes any lumps or cooked egg bits for a perfectly smooth and silky custard, which is essential for the luscious texture that makes this Boston Cream Pie Recipe so special.
Can I substitute ingredients if needed?
While some substitutions are possible, such as using light corn syrup or other neutral oils, using fresh eggs, whole milk, and quality butter and chocolate will give you the best results to honor this classic dessert.

- Yield: 8 servings 1x
Description
Classic Boston Cream Pie features layers of tender sponge cake filled with smooth, vanilla-flavored pastry cream and topped with a glossy chocolate ganache. This elegant dessert combines rich textures and balanced sweetness, perfect for special occasions or anytime you crave a nostalgic treat.
Ingredients
Pastry Cream
- ½ cup granulated sugar
- ¼ cup cornstarch
- 2 cups whole milk
- 4 large egg yolks
- 3 tablespoons unsalted butter, sliced
- 2 teaspoons pure vanilla extract
Sponge Cake
- 2 cups all-purpose flour, spooned and leveled
- 2 teaspoons baking powder
- ½ teaspoon salt
- ½ cup unsalted butter, sliced and at room temperature
- 1 cup whole milk
- 4 large eggs, at room temperature
- 2 cups granulated sugar
- 2 tablespoons vegetable or canola oil
- 2 teaspoons pure vanilla extract
Chocolate Ganache
- 4 ounces semi-sweet chocolate, chopped
- 1 tablespoon light corn syrup (optional, for shine)
- ½ cup heavy whipping cream
Instructions
- Prepare the Pastry Cream: In a large saucepan, whisk together sugar and cornstarch. In a separate bowl, whisk milk and egg yolks until fully combined. Gradually pour this mixture into the saucepan while whisking continuously. Cook over medium heat, stirring often, until the mixture boils and thickens, about 1 minute. Remove from heat and stir in butter, one tablespoon at a time, then add vanilla extract. Strain the pastry cream through a fine-mesh sieve into a heatproof bowl. Cover the surface with plastic wrap to prevent a skin from forming. Refrigerate for at least 2 hours until chilled.
- Prepare the Sponge Cake: Preheat the oven to 350°F (180°C). Grease and line two 9-inch cake pans with parchment paper. In a bowl, sift together flour, baking powder, and salt. In a saucepan, heat the butter and milk over medium heat until it simmers, then remove from heat. In a separate bowl, beat eggs and sugar until light and fluffy, about 5 minutes. Mix in the oil and vanilla extract. Gently fold in the dry ingredients, then slowly pour in the warm milk and butter mixture, folding until fully combined. Divide the batter evenly into the prepared pans. Bake for 25-30 minutes, or until a toothpick inserted in the center comes out clean. Cool cakes in the pans for 20-30 minutes before transferring to a wire rack to cool completely.
- Assemble the Cake: Once the pastry cream is chilled, whisk it until smooth. Level the cake layers if necessary. Place one layer on a serving plate or cake stand. Pipe or spread the pastry cream onto the top, leaving a 1-inch border. Place the second cake layer upside-down on top and press gently. Refrigerate the assembled cake while preparing the ganache.
- Prepare the Chocolate Ganache: Place chopped chocolate and corn syrup in a bowl. Heat heavy cream in the microwave for 45-60 seconds until hot. Pour the hot cream over the chocolate and let it sit for 2 minutes to melt. Stir until smooth and glossy. Allow the ganache to cool for 15-20 minutes until thick but still pourable.
- Finish the Cake: Remove the cake from the refrigerator and pour the ganache evenly over the top, spreading it smoothly with a spatula. Refrigerate the cake for 1-2 hours to set the ganache before slicing and serving.
Notes
- For best results, use room temperature eggs and butter when making the sponge cake.
- Be sure to whisk the pastry cream constantly while cooking to avoid lumps and prevent curdling.
- If you don’t have corn syrup for the ganache, you can omit it; the chocolate will still be glossy but slightly less shiny.
- Allow the cake layers to cool completely before assembling to prevent melting the pastry cream.
- The cake can be assembled a day ahead and refrigerated; bring to room temperature before serving for best texture.
