The History of Boston Cream Pie Cupcakes
The original Boston Cream Pie isn’t actually a pie at all—it’s a cake. Created in the mid-19th century at the Parker House Hotel in Boston (now the Omni Parker House), this dessert was revolutionary for combining layers of sponge cake with pastry cream and topping it with a chocolate glaze. At the time, cakes were often baked in pie tins, which is likely how the name stuck. The combination of textures and flavors made it an instant classic and later earned it the title of Massachusetts’ official state dessert. Fast forward to modern times, and the cupcake craze of the early 2000s led bakers to reimagine traditional desserts in miniature forms. Thus, the Boston Cream Pie Cupcake was born—retaining all the hallmark components of the original but in a more accessible, personal-sized treat. These cupcakes blend American baking nostalgia with the European roots of custards and ganache, bringing old-world technique to contemporary dessert culture.
Ingredients Breakdown
For the Vanilla Cupcakes:
- 1½ cups all-purpose flour
- 1½ teaspoons baking powder
- ¼ teaspoon salt
- ½ cup unsalted butter, softened
- ¾ cup granulated sugar
- 2 large eggs
- 1½ teaspoons vanilla extract
- ½ cup whole milk
For the Pastry Cream Filling:
- 1½ cups whole milk
- ⅓ cup granulated sugar
- 3 large egg yolks
- 2 tablespoons cornstarch
- 1 teaspoon vanilla extract
- 2 tablespoons unsalted butter
For the Chocolate Ganache:
- ½ cup heavy cream
- 4 ounces semi-sweet chocolate, finely chopped
- 1 tablespoon unsalted butter (optional, for shine)
Step-by-Step Recipe:
- Make the Cupcakes: Preheat the oven to 350°F (175°C) and line a 12-cup muffin pan with cupcake liners. In a medium bowl, whisk together the flour, baking powder, and salt. In a separate bowl, cream the butter and sugar until light and fluffy. Add the eggs one at a time, beating well after each addition, then mix in the vanilla. Add the flour mixture in three parts, alternating with the milk, beginning and ending with the dry ingredients. Mix just until combined. Divide the batter evenly among the cupcake liners and bake for 18–22 minutes, or until a toothpick inserted in the center comes out clean. Cool completely on a wire rack.
- Make the Pastry Cream: In a medium saucepan over medium heat, warm the milk until just simmering. In a bowl, whisk together the sugar, egg yolks, and cornstarch until smooth. Slowly pour in the hot milk, whisking constantly to temper the eggs. Return the mixture to the saucepan and cook over medium heat, stirring constantly, until it thickens and bubbles. Remove from heat and stir in the butter and vanilla. Strain through a sieve into a bowl to ensure smoothness. Cover with plastic wrap directly on the surface and refrigerate until chilled.
- Prepare the Ganache: Heat the heavy cream in a small saucepan until it just begins to simmer. Pour over the chopped chocolate in a bowl and let sit for a minute. Stir until smooth and glossy. Stir in butter for extra shine if desired. Let cool slightly until it reaches a spoonable consistency.
- Assemble the Cupcakes: Using a small knife or cupcake corer, cut out the center of each cooled cupcake and fill with about a tablespoon of chilled pastry cream. Replace a portion of the cut-out cake to cover the filling. Spoon or pipe the ganache on top of each cupcake, letting it slightly drip down the sides for a classic look. Refrigerate for 15–20 minutes to set or serve immediately if you prefer a softer topping.
Tips for the Perfect Boston Cream Pie Cupcakes
Use room temperature ingredients for smoother batter and more even baking. Do not overmix the cupcake batter to maintain a tender crumb. For the smoothest pastry cream, strain it after cooking and always press plastic wrap directly onto the surface to avoid a skin from forming. Let both the cupcakes and the pastry cream cool completely before assembling to prevent melting. For clean and even filling, use a piping bag or small spoon and refill any sunken tops with a piece of the cut-out cupcake. Chill the ganache briefly if it’s too runny before spooning onto cupcakes. For an extra glossy ganache, add a teaspoon of corn syrup or butter. Serve cupcakes slightly chilled for a firmer texture or at room temperature for a softer, creamier experience.
Variations and Customizations
Swap vanilla cupcakes for chocolate or almond-flavored bases for a twist. Add a splash of coffee to the ganache for mocha flavor. Use white chocolate ganache for a different look and taste. Infuse the pastry cream with citrus zest, espresso powder, or flavored extracts like almond or coconut. For a boozy variation, add a teaspoon of rum or bourbon to the pastry cream. Use mini cupcakes for bite-sized party treats or jumbo ones for a bakery-style indulgence. Pipe a swirl of stabilized whipped cream on top of the ganache for a fancy touch. Make them gluten-free by using a 1:1 gluten-free flour blend and dairy-free by substituting plant-based milk, butter, and chocolate alternatives.
Health Considerations and Nutritional Value
Boston Cream Pie Cupcakes are a rich dessert best enjoyed in moderation. One cupcake typically ranges between 250–350 calories depending on size and ingredients. You can lighten the recipe by using low-fat milk in the pastry cream, reducing the sugar slightly, or opting for a light whipped ganache made with milk instead of cream. For a lower-cholesterol version, use an egg substitute in the pastry cream. Whole wheat flour can replace part of the all-purpose flour for added fiber, though it will alter the texture slightly. Avoid processed toppings to keep it as wholesome as possible, and consider portion control when serving. For those with dietary restrictions, these cupcakes can be adapted to be gluten-free, dairy-free, or even lower-sugar with the right ingredient swaps, but the traditional version is definitely a treat meant to be savored.
FAQ
Can I make these cupcakes ahead of time? Yes, the cupcakes, pastry cream, and ganache can all be made a day in advance and assembled the day of serving.
How should I store them? Store assembled cupcakes in an airtight container in the fridge for up to 3 days. Let sit at room temperature for 10–15 minutes before serving.
Can I freeze Boston Cream Pie Cupcakes? It’s best to freeze the cupcakes without filling or topping. Add the pastry cream and ganache after thawing.
Do I need a cupcake corer? No, a small paring knife works just fine to create space for the filling.
Can I use store-bought pudding instead of pastry cream? You can, but homemade pastry cream offers better flavor and consistency.
Why is my ganache too runny or thick? If too runny, let it cool more before using. If too thick, microwave for 5–10 seconds or stir in a splash of warm cream.
Can I use cake mix for the cupcakes? Yes, if you’re short on time, a vanilla cake mix works well—just elevate it with homemade pastry cream and ganache.

Ingredients
Method
- Preheat your oven to 350°F and line a 12-cup muffin tin with paper liners.
- In a mixing bowl, whisk together the flour, baking powder, and salt until combined.
- In a separate large bowl, beat the butter and sugar together until the mixture is light and fluffy, about 2 minutes. Add the eggs one at a time, beating well after each addition, then mix in the vanilla extract.
- Add the flour mixture and the milk to the butter mixture in alternating additions, beginning and ending with the flour mixture, mixing just until incorporated.
- Evenly divide the batter among the cupcake liners. Bake for 18 to 22 minutes, or until a toothpick inserted into the center of a cupcake comes out clean. Allow the cupcakes to cool completely on a wire rack.
- To prepare the pastry cream, whisk the egg yolks, sugar, and cornstarch in a bowl until smooth. In a small saucepan, heat the milk over medium heat until it begins to steam. Slowly pour the hot milk into the egg mixture while whisking constantly to temper the eggs. Pour the mixture back into the saucepan and cook, whisking continuously, until thickened. Remove from heat and stir in the butter and vanilla extract. Strain the cream through a fine-mesh sieve into a bowl, cover with plastic wrap pressed directly onto the surface, and chill in the refrigerator for at least 2 hours until fully cooled.
- To make the ganache, place the chopped chocolate in a heatproof bowl. Heat the heavy cream in a saucepan just until it begins to boil. Pour the hot cream over the chocolate and let it sit undisturbed for 5 minutes. Then stir until smooth and glossy. Allow the ganache to cool until it thickens to a pourable consistency, about 15 minutes.
- To assemble the cupcakes, use a paring knife to cut a small cone-shaped section out of the center of each cupcake. Fill the holes with pastry cream using a spoon or piping bag. Dip the tops of the filled cupcakes into the ganache, letting any excess drip off. Place the cupcakes in the refrigerator for about 30 minutes, or until the ganache is set.
