There’s something timeless and comforting about Boston cream pie. Growing up in Massachusetts, it was always a staple at family gatherings—especially on my dad’s birthday. My mom’s homemade version, with its tender vanilla cake, silky pastry cream, and rich chocolate glaze, filled the house with an aroma that made it impossible not to sneak a taste.
Now, I recreate those same nostalgic flavors in cupcake form. These Boston Cream Cupcakes are a fun, portable twist on the classic dessert, perfect for celebrations, bake sales, or simply treating yourself at home.

Ingredients
Pastry Cream
- 1 cup whole milk

- 3 tbsp cornstarch
- 1 tsp vanilla extract

Vanilla Cupcakes
- ½ cup unsalted butter, softened
- ½ cup vegetable oil
- 1¾ cups granulated sugar
- 4 large eggs (room temp)
- 1 tbsp vanilla extract
- 3 cups all-purpose flour
- 1 tbsp baking powder
- ½ tsp salt
- 1¼ cups buttermilk (room temp)
Chocolate Ganache
- 1 cup semisweet chocolate chips
- ½ cup heavy cream
- 2 tbsp light corn syrup (optional, for shine)
- ¼ cup confectioners’ sugar, sifted
Instructions
1. Make the Pastry Cream
- In a saucepan, combine milk, cream, ¼ cup sugar, and salt. Heat over medium until steaming; stir often. Remove from heat.
- In a bowl, whisk yolks with remaining sugar until smooth. Add cornstarch and mix until lump-free.
- Slowly whisk in ⅓ of the hot milk to temper the yolks. Then, pour yolk mixture back into the saucepan.
- Return to heat, whisking constantly, until thickened (2–3 minutes).
- Strain into a clean bowl. Stir in vanilla and butter. Cover with plastic wrap directly on the surface and chill for at least 2 hours.
2. Make the Cupcakes
- Preheat oven to 350°F (175°C). Line two 12-cup muffin tins with liners.
- Beat butter, oil, and sugar until light and fluffy (about 2 minutes). Add eggs one at a time, then vanilla.
- In a separate bowl, whisk flour, baking powder, and salt.
- Alternately add dry ingredients and buttermilk to the wet mixture in three additions, mixing gently.
- Divide batter evenly into liners, filling each about ¾ full.
- Bake for 18–20 minutes, or until a toothpick comes out with moist crumbs. Cool completely.
3. Make the Ganache
- Combine chocolate chips, cream, and corn syrup (if using) in a microwave-safe bowl. Microwave in 20-second intervals, stirring until smooth.
- Whisk in confectioners’ sugar. Let sit 10–15 minutes to thicken slightly.
4. Assemble the Cupcakes
- Cut a cone-shaped cavity into each cupcake with a paring knife. Remove the plug and trim the tip to create a flat “lid.”
- Fill each cavity with chilled pastry cream using a piping bag. Replace the lid.
- Spoon ganache over each cupcake. Chill until ready to serve.
Tips & FAQs
Can I use pudding instead of pastry cream?
You can, but real pastry cream gives that rich, authentic flavor and texture.
Is the corn syrup necessary in the ganache?
Not at all—it’s optional and just helps give a glossy finish.
Can I freeze these?
Freezing is not recommended. The pastry cream can become watery when thawed. Store in the fridge for up to 5 days instead.
How do I get a clean cupcake cavity?
Use a paring knife to cut a neat cone shape and slice off the tip before replacing the top after filling.
