Pin Boston Cream Pie Cupcakes might just be the most nostalgic and crowd-pleasing treat ever layered with creamy custard and topped with glossy chocolate ganache. I fell in love with these after making them for my son’s school birthday party everyone asked for the recipe and there was not a crumb left on the tray
My first time baking these I was blown away by how much they reminded me of classic Boston cream pie but with a fun handheld twist. These are a staple for family birthdays now and always disappear fast
Ingredients
- Yellow cake mix: use your favorite brand for a fluffy cupcake base check for mixes with natural vanilla for best flavor
- Eggs, oil and water for cake mix: always use fresh eggs and neutral-flavored oil for the lightest cupcakes
- Whole milk: gives the pastry cream extra richness opt for milk with a long freshness date
- Granulated sugar: sweetens both the cream and cupcakes look for superfine sugar to help it dissolve smoothly
- Cornstarch: thickens the cream make sure yours is lump free and fresh
- Large egg yolks: enrich the custard for vibrant color and texture
- Unsalted butter: adds silkiness to the filling use high-quality for the creamiest result
- Vanilla extract: rounds out the flavor real vanilla makes a big difference here
- Heavy cream: forms the base of the ganache
- Semi-sweet chocolate for ganache: richer flavor comes from high cocoa content try to use real chocolate versus chips for smoothness
Instructions
- Make the Cupcakes:
- Bake the boxed yellow cake mix as directed for cupcakes using fresh eggs and oil for best results. Allow cupcakes to cool fully before filling to prevent melting the cream
- Prepare Pastry Cream:
- Whisk milk sugar cornstarch and egg yolks together in a heavy saucepan. Heat gently over medium whisking constantly to prevent lumps. Keep stirring until the mixture thickens and starts to bubble this cooks out the flour taste and ensures a silky custard. Once thick remove from the heat and beat in butter and vanilla blend well for a glossy smooth finish. Press plastic wrap directly on the surface to avoid a skin forming and chill until cold
- Fill Cupcakes:
- Gently carve out a small core from each cupcake using a paring knife or cupcake corer. Pipe or spoon in chilled pastry cream until level with the cake
- Make Chocolate Ganache:
- Bring heavy cream just to a simmer on the stove. Pour immediately over chopped chocolate in a bowl and let sit then stir until completely smooth and glossy
- Glaze and Finish:
- Spoon a generous layer of ganache over each filled cupcake letting it set slightly until just tacky before serving for the most indulgent finish
Pin Whenever I make these I always sneak a little extra pastry cream into my own cupcake to savor the creamy center. My kids love being on ganache duty each cupcake ends up with its own chocolate swirl pattern and it has become the most anticipated part of birthday celebrations
Storage Tips
Store these cupcakes covered in the refrigerator as the pastry cream needs to stay chilled to be food safe. They stay fresh and soft for up to three days. If stacking them add a piece of parchment between layers so the ganache does not stick. I recommend letting them sit at room temperature for 20 minutes before serving for the best creamy texture
Ingredient Substitutions
You can easily swap the vanilla cake for chocolate or even a lighter sponge for a different twist. For a dairy-free version use coconut milk in the pastry cream and coconut cream in the ganache. If you do not have real chocolate bars for the ganache quality chocolate chips work in a pinch just melt them carefully to avoid seizing
Serving Suggestions
These cupcakes shine solo at parties but also look stunning on a dessert platter sprinkled with gold dust or chopped toasted almonds. For extra flair pipe a spiral of whipped cream on top then drizzle with ganache. They make a great surprise in lunchboxes or movie night snacks
Cultural and Historical Context
Boston Cream Pie is a Massachusetts icon since the nineteenth century originally a layered cake filled with custard and poured over with chocolate glaze. Turning it into cupcakes brings the nostalgia of diner classics to modern family gatherings and makes sharing easy. You get familiar flavors in a much more portable and festive package
Pin Enjoy these cupcakes for every celebration they might even outshine the birthday cake.
