Delicious Boston Cream Cupcakes filled with custard and topped with chocolate ganache.
Ingredients
Scale
- 1 ½ cups all-purpose flour
- 1 cup granulated sugar
- 1 ½ teaspoons baking powder
- ½ teaspoon salt
- ½ cup unsalted butter, room temperature
- 2 large eggs
- ½ cup whole milk
- 1 teaspoon vanilla extract
- 1 cup whole milk (for custard filling)
- 3 egg yolks (for custard filling)
- ⅓ cup granulated sugar (for custard filling)
- 2 tablespoons cornstarch (for custard filling)
- 1 teaspoon vanilla extract (for custard filling)
- 1 cup heavy cream (for ganache)
- 8 ounces semi-sweet chocolate, chopped (for ganache)
Instructions
- Preheat your oven to 350°F (175°C). Line a muffin tin with cupcake liners.
- In a large bowl, whisk together the flour, sugar, baking powder, and salt.
- Add the butter, eggs, milk, and vanilla extract. Beat with a mixer until the batter is smooth and well combined.
- Fill each cupcake liner about ⅔ full with batter.
- Bake for 18–20 minutes, or until a toothpick inserted into the center comes out clean. Allow the cupcakes to cool completely.
- In a medium saucepan, whisk together the milk, egg yolks, sugar, and cornstarch for the custard filling.
- Cook over medium heat, stirring constantly, until the mixture thickens and coats the back of a spoon.
- Remove from heat and stir in the vanilla extract for the custard filling.
- Transfer the custard to a bowl, cover with plastic wrap (press the wrap directly onto the surface to prevent a skin from forming), and chill until fully cooled.
- Heat the heavy cream in a small saucepan over medium heat for the ganache until it just begins to boil.
- Pour the hot cream over the chopped chocolate in a bowl. Let sit for 5 minutes, then stir until smooth and glossy.
- Using a paring knife or cupcake corer, cut a small hole in the top center of each cupcake.
- Fill each hole with a spoonful of chilled custard filling.
- Spoon or dip the tops of the cupcakes into the ganache to coat.
- Let the ganache set for 10–15 minutes, or refrigerate for a firmer texture.
- Serve the cupcakes at room temperature and enjoy!
Notes
- Use room temperature ingredients for better mixing.
- Store leftover cupcakes in an airtight container in the fridge.
- The custard filling can be made a day ahead and stored in the fridge.
- Use high-quality chocolate for the ganache for the best flavor.
