There’s something magical about transforming beloved classic desserts into personal-sized treats. As someone who’s been baking for over a decade, I can tell you that these Boston Cream Pie Cupcakes are pure joy – little vessels of vanilla cake filled with silky pastry cream and topped with rich chocolate ganache. Today, I’m sharing my foolproof recipe that brings the elegant charm of Boston Cream Pie to a hand-held format.
A Little History in Every Bite
Before we dive into the recipe, let me share something fascinating – Boston Cream Pie was first created in 1856 at Boston’s Parker House Hotel (now the Omni Parker House Hotel). The original dessert wasn’t actually a pie at all, but rather a cake filled with vanilla custard and topped with chocolate glaze. In 1996, it was even named the official dessert of Massachusetts! Our cupcake version honors this heritage while adding a modern, portable twist.

The Recipe Breakdown
For the Vanilla Cupcakes:
- 1¾ cups all-purpose flour
- 1½ teaspoons baking powder
- ¼ teaspoon salt
- ¾ cup unsalted butter, room temperature
- 1½ cups granulated sugar
- 3 large eggs, room temperature
- 2 teaspoons pure vanilla extract
- ¾ cup whole milk, room temperature
For the Pastry Cream Filling:
- 2 cups whole milk
- ⅔ cup granulated sugar
- ¼ cup cornstarch
- ¼ teaspoon salt

For the Chocolate Ganache:
- 8 ounces semi-sweet chocolate, finely chopped
- 1 cup heavy cream
- Pinch of salt
Step-by-Step Instructions
Making the Vanilla Cupcakes:
- Preheat your oven to 350°F (175°C). Line your muffin tin with cupcake liners.
- In a medium bowl, whisk together the flour, baking powder, and salt. Set aside.
- In your stand mixer bowl (or using a hand mixer), cream the butter and sugar until light and fluffy, about 3-4 minutes. Don’t rush this step – it’s crucial for achieving that perfect texture!
- Add eggs one at a time, beating well after each addition. Scrape down the sides of the bowl as needed. Mix in the vanilla extract.
- Gradually add the flour mixture alternating with milk, beginning and ending with flour (I do this in three additions of flour and two of milk). Mix until just combined.
- Fill each cupcake liner about ⅔ full with batter.
- Bake for 18-20 minutes, or until a toothpick inserted comes out clean.
- Cool in the pan for 5 minutes, then transfer to a wire rack to cool completely.
Creating the Pastry Cream:
- In a medium saucepan, heat milk until it just starts to simmer. Remove from heat.
- Meanwhile, in a bowl, whisk together sugar, cornstarch, salt, and egg yolks until smooth.
- Slowly stream about ⅓ of the hot milk into the egg mixture, whisking constantly (this tempers the eggs).
- Pour the tempered egg mixture back into the remaining milk in the saucepan.
- Cook over medium heat, whisking constantly, until the mixture thickens and begins to bubble (about 5-7 minutes).
- Remove from heat and 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 until completely cool, at least 2 hours.
Making the Chocolate Ganache:
- Place chopped chocolate in a heat-safe bowl.
- Heat heavy cream in a small saucepan until it just begins to simmer.
- Pour hot cream over chocolate and let stand for 5 minutes.
- Whisk until smooth and glossy. Add a pinch of salt.
- Let cool until slightly thickened but still pourable.
Assembly Time!
- Once cupcakes are completely cool, use a small knife or cupcake corer to remove the centers, creating a well for the filling.
- Fill a pastry bag fitted with a round tip with the chilled pastry cream.
- Pipe the cream into each cupcake cavity, filling just to the top.
- Spoon or pour the ganache over each filled cupcake, allowing it to drip slightly down the sides.
- Refrigerate for about 15 minutes to set the ganache.
Pro Tips from My Kitchen
- Room temperature ingredients are crucial for the cupcake batter – they’ll blend more evenly and create a better texture.
- Don’t overmix the cupcake batter once you add the flour, or you’ll end up with tough cupcakes.
- When making the pastry cream, constant whisking is your best friend to prevent lumps.
- The ganache should be warm enough to pour but not so hot that it melts the pastry cream.
- Store these cupcakes in the refrigerator, but serve them slightly closer to room temperature for the best flavor.
Troubleshooting Common Issues
| Problem | Cause | Solution |
|---|---|---|
| Cupcakes are dense | Overmixing or cold ingredients | Mix just until combined; ensure room temp ingredients |
| Pastry cream is lumpy | Inadequate whisking or overheating | Strain through a sieve; watch temperature carefully |
| Ganache is too thick | Chocolate to cream ratio off | Add warm cream 1 tablespoon at a time |
| Filling leaks out | Too much filling or thin pastry cream | Fill less; ensure pastry cream is properly thickened |
| Uneven cupcakes | Uneven batter distribution | Use an ice cream scoop for consistent portions |
Storage and Make-Ahead Tips
These cupcakes can be stored in an airtight container in the refrigerator for up to 3 days. The components can also be made ahead:
- Unfilled cupcakes: 1 day at room temperature
- Pastry cream: up to 3 days refrigerated
- Ganache: can be made 24 hours ahead and rewarmed
Serving Suggestions
- Serve with fresh berries for a fruity contrast
- Add a sprinkle of powdered sugar for extra elegance
- Pair with hot coffee or milk for the perfect afternoon treat
- Consider serving on a dessert platter with fresh mint leaves for decoration
Questions & Answers
Q: Can I make these cupcakes ahead for a party?
Yes! You can make the components up to 2 days ahead and assemble the morning of your event.
Q: What’s the best way to core the cupcakes?
I recommend using a cupcake corer, but a small sharp knife works well too. Cut a cone shape about 1 inch deep, keeping the removed cake to make a cap if desired.
Q: Can I use milk chocolate for the ganache?
While you can, I find semi-sweet chocolate provides the perfect balance. Milk chocolate can make the cupcakes overly sweet.
Q: Why did my pastry cream turn lumpy?
This usually happens if the eggs weren’t properly tempered or the mixture was cooked too quickly. Strain through a fine-mesh sieve to salvage it.
Q: Can I freeze these cupcakes?
I don’t recommend freezing the assembled cupcakes, but you can freeze the unfilled cupcakes for up to 2 months.
