- Milk (for filling): For creaminess—whole milk works best for the silkiest texture.
- Sugar (for filling): Keeps the pastry cream perfectly sweet without being cloying.

- Salt (for filling): Just a pinch to keep the filling balanced.

Variations
Interested in mixing things up? These cupcakes are a great blank canvas:
- Flavor the Pastry Cream: Swirl in a little espresso powder, citrus zest, or almond extract for a fun twist.
- Different Ganache Toppings: Use milk chocolate, white chocolate, or even a salted caramel drizzle instead of the classic semi-sweet ganache.
- Cupcake Base Swap: Try chocolate cupcakes for a double chocolate version, or add a little lemon zest to the cupcake batter for a brighter flavor.
- No Piping Bag? Just use a small spoon and cut out a little core from each cupcake to fill them with pastry cream.
How to Make Boston Cream Pie Cupcakes
Step 1: Prepare the Cupcakes
Start by creaming the butter and sugar until pale and fluffy—the base for a tender cupcake. Blend in the vanilla, then add the eggs one at a time, mixing thoroughly after each. In a separate bowl, whisk together the flour, baking powder, and salt. Alternate adding the dry ingredients and buttermilk to the butter mixture, beginning and ending with the flour. This ensures maximum fluffiness! Divide the batter among lined muffin pans and bake until golden and a toothpick comes out clean. Allow them to cool completely before filling.
Step 2: Make the Pastry Cream Filling
Beat your egg yolks and gradually whisk in the milk until totally smooth. In a heavy saucepan, mix the sugar, cornstarch, and salt. Slowly add the egg-milk mixture, stirring constantly to avoid lumps. Cook over medium-low, stirring until the mixture thickens and bubbles (this usually takes about 20 minutes—slow and steady wins the race here). Once thickened, remove from heat, stir in the vanilla, and cool quickly by placing the pot in an ice bath. Cover with plastic wrap pressed directly onto the surface and refrigerate until cold and thick.
Step 3: Prepare the Ganache
Chop your semi-sweet chocolate finely (or blitz in a food processor), then pour over heated heavy cream. Allow it to sit for a minute, then gently whisk until the ganache is lusciously smooth and glossy. Cool slightly before dipping.
Step 4: Fill and Dip
Fill a piping bag fitted with a filling tip (or use a zip-top bag with a corner snipped off) with the cooled pastry cream. Gently pipe the cream into the center of each cooled cupcake. Once filled, carefully dip the tops into the cooled ganache and let them set for at least 30 minutes so the topping firms up just right.
Pro Tips for Making the Recipe
- Room Temperature Ingredients: Make sure butter, eggs, and buttermilk are all at room temperature for the fluffiest cake.
- Go Slow with Pastry Cream: Stir constantly and don’t rush it—the payoff is that silky, dreamy filling.
- Cool Everything Properly: Don’t fill or frost cupcakes until both the cakes and the fillings are completely cool, or you’ll risk melted filling or runny ganache.
- Keep It Neat: If you don’t have a filling tip, cut a small core from the top of each cupcake using a paring knife, fill with cream, and replace the ‘cap’ before dipping in ganache.
How to Serve
These cupcakes really are a dessert on their own, but a few thoughtful extras can make them stand out even more:
- Serve them on a pretty platter at room temperature for the smoothest pastry cream texture.
- Pair with a strong cup of coffee, black tea, or even a glass of cold milk—these flavors work together beautifully.
- For a festive occasion, dust with a little powdered sugar, or top with a berry for added color and brightness.
Make Ahead and Storage
Storing Leftovers
Keep any extra cupcakes in the refrigerator in an airtight container for up to 2-3 days. The pastry cream keeps them moist, so they stay delicious!
Freezing
While you can freeze the cupcake bases, pastry cream can sometimes separate after freezing and thawing, so it’s best to freeze the cupcakes before filling and frost them fresh.
Reheating
No need to reheat! Bring refrigerated cupcakes to room temperature about 30 minutes before serving, so the pastry cream softens and the ganache is delightfully fudgy.
FAQs
-
Can I make the components in advance?
Absolutely. You can bake the cupcakes, prepare the filling, and make the ganache one or even two days ahead. Keep each separately in the fridge and assemble them just before serving for the freshest results.
-
I don’t have buttermilk—what should I use?
No worries! Mix regular milk with a splash of lemon juice or vinegar, let it sit for 5 minutes, and you’ve got a perfect buttermilk substitute.
-
Can I use a boxed cake mix or pudding?
Definitely, when you’re short on time, a good-quality vanilla cake mix and instant pudding mix work in a pinch—just keep homemade ganache for the best flavor.
-
Is there a way to make these gluten-free?
Yes, you can substitute your favorite gluten-free flour blend for the regular flour in the cupcakes. Be sure it’s a 1:1 baking blend for best results.

Description
These Boston Cream Pie Cupcakes bring all the luxurious flavors of the classic dessert into individual cupcake form: soft vanilla cake filled with rich pastry cream and topped with silky chocolate ganache. Perfect for parties, special occasions, or whenever you want an elegant, indulgent treat.
Ingredients
For the Cake
- 12 tablespoons unsalted butter, softened
- 1 cup sugar
- 2 teaspoons vanilla extract
- 3 large eggs
- 1 1/2 cups all-purpose flour
- 2 teaspoons baking powder
- 1/2 teaspoon salt
- 2/3 cup buttermilk
For the Filling
- 3 large egg yolks
- 3 cups milk
- 1/2 cup sugar
- 1/3 cup cornstarch
- 1/4 teaspoon salt
- 1 teaspoon vanilla extract
For the Ganache
- 8 ounces semi-sweet baking chocolate, finely chopped
- 1 cup heavy cream
Instructions
- Prepare the Cake Batter – In a large mixing bowl, cream together the softened butter and sugar until light and fluffy. Add the vanilla extract and beat again. Add in the eggs, one at a time, beating well after each addition. In a separate bowl, stir together the flour, baking powder, and salt. Alternate adding the flour mixture and buttermilk to the creamed mixture in 3 batches, starting and ending with the dry ingredients. Beat after each addition, just until combined.
- Bake the Cupcakes – Line a lightly greased muffin pan with cupcake liners. Fill each liner ¾ of the way full with batter. Bake in a preheated 350°F (175°C) oven for 18-25 minutes, or until a toothpick inserted in the center comes out clean. Remove from the oven and cool completely on a wire rack.
- Prepare the Pastry Cream Filling – In a medium bowl, beat the egg yolks well and gradually stir in the milk until blended. In a large, heavy saucepan over medium-low heat, combine the sugar, cornstarch, and salt. Gradually add the milk mixture to the pan, stirring constantly to prevent lumps. Continue to cook, stirring constantly, until the mixture reaches a low boil and thickens (about 20 minutes). Remove from heat, set the pot in a large bowl of ice water, and stir in the vanilla extract. Place a piece of plastic wrap directly onto the surface of the filling and refrigerate until ready to use.
- Make the Chocolate Ganache – Place the chopped chocolate in a food processor and pulse until finely chopped. Transfer to a mixing bowl. In a small saucepan, heat the heavy cream just until steaming (not boiling). Gradually pour the hot cream over the chocolate and whisk until smooth and glossy. Allow it to cool until slightly thickened but still pourable.
- Fill and Glaze the Cupcakes – When the cupcakes are completely cool, transfer the pastry cream filling to a piping bag with a filling tip. Insert the tip into the center of each cupcake and fill with the cream. Dip the tops of the filled cupcakes into the cooled ganache to coat. Place cupcakes on a rack or tray and allow 30 minutes to 1 hour for the ganache to set.
Notes
- Homemade pastry cream yields the best flavor but a prepared boxed pudding mix can be substituted in a pinch.
- Let the ganache cool for 10-20 minutes before dipping the cupcakes so it’s not too runny.
- For more tips on making ganache, refer to a dedicated ganache tutorial or post if needed.
- Store cupcakes in the refrigerator for up to 2-3 days and bring to room temperature 30 minutes before serving.
- To make ahead, prep cupcakes, filling, and ganache separately and assemble just before serving.
