Ingredients You’ll Need
The beauty of this Boston Cream Pie Recipe lies in its simple, straightforward ingredients that come together to create something truly special. Each item plays a critical role, whether it’s the delicate crumb of the sponge cake, the silky texture of the pastry cream, or the rich finish of the chocolate glaze.
- All-purpose flour (1 1/4 cups): Provides the sturdy yet tender structure for the cake layers.
- Baking powder (1 1/2 teaspoons): Helps the cake rise to a light and fluffy texture.
- Salt (1/4 teaspoon): Balances sweetness and enhances overall flavors.
- Large eggs, room temperature (3 eggs + 6 yolks): Eggs add richness and help create the cake’s tender crumb and the custard’s creamy consistency.
- Granulated sugar (1 cup + 1/2 cup): Sweetens both cake and custard perfectly without overpowering.
- Whole milk (1/2 cup + 2 cups): Adds moisture to the cake and creaminess to the custard.
- Unsalted butter (4 tablespoons + 2 tablespoons): Gives the cake a soft texture and enriches the pastry cream.
- Vanilla extract (1 teaspoon + 1 teaspoon): Brings a warm, aromatic note to both cake and custard.
- Cornstarch (1/4 cup): Thickens the pastry cream for a smooth, spoonable filling.
- Bittersweet chocolate, chopped (4 ounces): Makes the luscious ganache that tops the pie.
- Heavy cream (1/2 cup): Creates the silky texture of the chocolate glaze.
- Light corn syrup (1 tablespoon, optional): Adds shine and gloss to the chocolate ganache, making it look professionally finished.
How to Make Boston Cream Pie Recipe
Step 1: Bake the Sponge Cake
Begin by preheating your oven to 350°F (175°C) and preparing two 9-inch cake pans with butter and parchment paper. In a bowl, sift together the flour, baking powder, and salt. In a separate large bowl, beat the eggs and 1 cup of sugar until pale and fluffy—this will give your cake a light texture. Warm the 1/2 cup of milk with the butter just until melted, then stir in the vanilla extract. Gently fold the dry ingredients and milk mixture into the egg mixture, being careful not to overmix. Divide the batter evenly between the pans and bake for approximately 25-30 minutes, or until a toothpick inserted comes out clean. Let the cakes cool completely before assembling.
Step 2: Prepare the Pastry Cream
While the cakes cool, it’s time to make the luscious pastry cream that makes this Boston Cream Pie Recipe unforgettable. In a medium saucepan, heat 2 cups of whole milk until it starts to steam but not boil. Meanwhile, whisk the 6 egg yolks, 1/2 cup sugar, and cornstarch together until smooth and pale. Slowly pour the hot milk into the egg mixture while whisking constantly to prevent curdling. Return everything to the saucepan and cook over medium heat, stirring continuously until the custard thickens enough to coat the back of a spoon. Remove from heat and stir in butter and vanilla extract. Cover with plastic wrap pressed directly on the surface to prevent a skin from forming, and chill until firm.
Step 3: Make the Chocolate Ganache
To finish off the Boston Cream Pie Recipe, the chocolate ganache is a must. Place your chopped bittersweet chocolate in a heatproof bowl. Heat the heavy cream and optional light corn syrup just to a simmer, then pour it over the chocolate. Let it sit for a minute or two, then stir gently until smooth and glossy. Allow the ganache to cool slightly so it thickens but remains pourable for glazing.
Step 4: Assemble the Boston Cream Pie
Slice each sponge cake in half horizontally to create four thin layers. Place the first layer on your serving plate, spread a generous amount of chilled pastry cream over it, then add the second layer. Repeat until all layers are stacked, finishing with cake on top. Pour the warm ganache evenly over the assembled cake, allowing it to drip artfully down the sides. Chill the cake to set the ganache before serving.
How to Serve Boston Cream Pie Recipe
Garnishes
While this Boston Cream Pie Recipe is stunning on its own, adding a few thoughtful garnishes can elevate its presentation. Consider a light dusting of powdered sugar around the edges or a few fresh berries for pops of color. Mint leaves can also brighten up the plate, lending a fresh contrast to the rich chocolate and custard.
Side Dishes
Because this dessert is rich and satisfying, simpler sides complement it well. A cup of strong black coffee or a bold espresso pairs beautifully, cutting through the sweetness. For something lighter, serve with a simple mixed green salad with a tangy vinaigrette to refresh the palate between bites.
Creative Ways to Present
If you want to get a little playful, try turning your Boston Cream Pie Recipe into individual mini cakes using rings or ramekins. Layer the components and top each with its own drizzle of chocolate ganache for a personalized touch. Alternatively, turn leftover pastry cream into cups or parfait glasses layered with cake crumbs and garnished with chocolate shavings.
Make Ahead and Storage
Storing Leftovers
Leftover Boston Cream Pie should be kept in the refrigerator, covered tightly with plastic wrap or in an airtight container, to maintain its freshness. The custard filling is delicate, so it’s best enjoyed within 3 days for the best texture and flavor.
Freezing
Freezing this dessert is possible, but not ideal due to the custard layer which can separate and become watery when thawed. If you choose to freeze, wrap the slices securely in plastic and foil and consume within one month. Thaw slowly in the refrigerator before serving.
Reheating
Boston Cream Pie is best served chilled, so reheating isn’t recommended. If your ganache thickens after refrigeration, allow the cake to sit at room temperature for 15-20 minutes before slicing, which will soften everything nicely.
FAQs
Is Boston Cream Pie actually a pie?
No, despite the name, Boston Cream Pie is not a pie. It is a layered sponge cake filled with pastry cream and topped with chocolate ganache. The term “pie” is a historical reference dating back to when cakes and pies shared baking pans and names.
Can I use other types of chocolate for the ganache?
Absolutely! While bittersweet chocolate offers the perfect bittersweet balance, you can use semisweet, milk, or even white chocolate to suit your taste. Just adjust sweetness accordingly since milk and white chocolates are sweeter.
How do I prevent the custard from curdling?
Whisking constantly and tempering the egg yolks by gradually adding hot milk helps prevent curdling. Cooking the custard over medium heat and removing it from heat as soon as it thickens to coat the spoon will keep it smooth.
Can I make this recipe gluten-free?
Yes! You can substitute the all-purpose flour with a gluten-free baking blend that measures cup for cup. Be sure the blend contains xanthan gum or another binder to mimic the cake’s texture.
What’s the best way to slice Boston Cream Pie?
Use a sharp, serrated knife and dip it in hot water before slicing to get clean cuts through the layers. Wipe the knife clean between slices to keep edges neat and prevent mixing layers.

Ingredients
For the Cake:
- 1 1/4 cups all-purpose flour
- 1 1/2 teaspoons baking powder
- 1/4 teaspoon salt
- 3 large eggs (room temperature)
- 1 cup granulated sugar
- 1/2 cup whole milk

For the Pastry Cream:
- 2 cups whole milk
- 6 large egg yolks
- 1/2 cup granulated sugar
- 1/4 cup cornstarch
- 1 teaspoon vanilla extract
- 2 tablespoons unsalted butter
For the Chocolate Glaze:
- 4 ounces bittersweet chocolate (chopped)
- 1/2 cup heavy cream
- 1 tablespoon light corn syrup (optional, for shine)
Instructions
- Prepare the Cake Batter: Preheat your oven to 350°F (175°C). In a medium bowl, sift together the all-purpose flour, baking powder, and salt. In a separate large bowl, beat the eggs and granulated sugar until thick and pale. Warm the milk with the butter until the butter melts, then add the vanilla extract. Gradually fold the dry ingredients and the warm milk mixture into the egg mixture, combining gently until smooth.
- Bake the Cake: Grease and flour two 9-inch round cake pans. Divide the cake batter evenly between the pans. Bake in the preheated oven for about 35-40 minutes or until a toothpick inserted into the center comes out clean. Let the cakes cool in their pans for 10 minutes, then turn out onto wire racks to cool completely.
- Make the Pastry Cream: In a saucepan, heat the whole milk until it just begins to simmer. In a separate bowl, whisk together the egg yolks, sugar, and cornstarch until smooth. Temper the egg mixture by slowly adding some of the hot milk while whisking constantly, then pour the egg mixture back into the saucepan. Cook over medium heat, whisking constantly, until the mixture thickens and comes to a boil. Remove from heat and stir in the vanilla extract and butter. Transfer to a bowl, cover with plastic wrap directly on the surface, and chill until fully cooled.
- Prepare the Chocolate Glaze: Place the chopped bittersweet chocolate in a heatproof bowl. Heat the heavy cream and light corn syrup in a small saucepan just until it starts to simmer, then pour it over the chocolate. Let sit for a minute, then stir until smooth and glossy.
- Assemble the Boston Cream Pie: Place one cake layer on a serving plate and spread the chilled pastry cream evenly on top. Place the second cake layer over the cream. Pour the chocolate glaze over the top, allowing it to drip down the sides. Refrigerate for at least one hour before serving to set the glaze and enhance flavors.
Notes
- Make sure eggs are at room temperature for better volume in the batter.
- Use a fine sieve if needed to remove any lumps in the pastry cream for a smoother texture.
- Light corn syrup in the chocolate glaze is optional but helps achieve a shiny finish.
- Best served slightly chilled.
- Can be stored in the refrigerator covered for up to 3 days.
