Ingredients
For the Cupcakes:
- 1 ½ cups all-purpose flour
- 1 ½ teaspoons baking powder
- ¼ teaspoon salt
- ½ cup unsalted butter, softened
- ¾ cup granulated sugar
- 2 eggs
- 1 teaspoon vanilla extract
- ½ cup whole milk
For the Pastry Cream Filling:
- 1 cup whole milk
- ¼ cup granulated sugar
- 2 egg yolks
- 1 tablespoon cornstarch
- ½ teaspoon vanilla extract
- ½ tablespoon unsalted butter
For the Chocolate Ganache:
- ½ cup semi-sweet chocolate chips
- ¼ cup heavy cream
- ½ tablespoon unsalted butter (for shine)
Instructions
Step 1: Make the Cupcakes
- Preheat the oven to 350°F (175°C). Line a muffin tin with 12 cupcake liners.
- In a medium bowl, whisk together the flour, baking powder, and salt.
- In a separate large bowl, beat the butter and sugar together until light and fluffy, about 2 minutes.
- Add the eggs one at a time, beating well after each addition. Stir in the vanilla extract.
- Gradually add the dry ingredients, alternating with the milk, mixing until just combined.
- Divide the batter evenly into the cupcake liners, filling each about ¾ full.
- Bake for 18–20 minutes, or until a toothpick inserted into the center comes out clean. Let the cupcakes cool completely before filling.
Step 2: Make the Pastry Cream
- In a saucepan, heat the milk over medium heat until steaming, but not boiling.
- In a bowl, whisk together the sugar, egg yolks, and cornstarch until smooth.
- Slowly pour the hot milk into the egg mixture, whisking constantly to prevent curdling.
- Return the mixture to the saucepan and cook over medium heat, whisking constantly until thickened, about 3 minutes.
- Remove from heat and stir in the vanilla extract and butter.
- Transfer the pastry cream to a bowl, cover with plastic wrap touching the surface, and chill in the refrigerator for at least 30 minutes.
Step 3: Make the Chocolate Ganache
- Heat the heavy cream in a microwave or small saucepan until steaming, but not boiling.
- Pour the hot cream over the chocolate chips and let it sit for 1 minute.
- Stir until smooth and glossy, then add the butter and mix until melted. Let it cool slightly.
Step 4: Assemble the Cupcakes
- Fill the Cupcakes: Use a small knife or cupcake corer to cut out the center of each cupcake.
- Spoon or pipe the chilled pastry cream into each hole.
- Top with Ganache: Spoon or dip the tops of the cupcakes into the chocolate ganache.
- Let the ganache set for about 10 minutes before serving.
Step 5: Serve & Enjoy!
- Serve the cupcakes at room temperature for the best flavor.
- Store any leftovers in the refrigerator for up to 3 days.
Tips for Success
- Want it Extra Creamy? Substitute half of the milk with heavy cream in the pastry cream for an even richer texture.
- Ganache Too Thick? Add 1–2 teaspoons of warm milk to loosen the ganache if it becomes too thick.
- Make-Ahead Friendly! Prepare the cupcakes and pastry cream a day in advance, then assemble before serving.
These Boston Cream Cupcakes are the perfect indulgence—light, fluffy cupcakes with a creamy center and rich chocolate topping. They are surprisingly easy to make and will impress anyone lucky enough to taste them!
