Boston Cream Cupcakes are a delightful twist on the classic Boston Cream Pie. These cupcakes feature a rich custard filling, topped with a luscious chocolate ganache. Here’s a step-by-step guide to making these delicious treats from scratch:
Ingredients
For the Cupcakes:
- 1 1/2 cups all-purpose flour
- 1 1/2 teaspoons baking powder
- 1/2 teaspoon salt
- 1/2 cup unsalted butter, softened
- 1 cup granulated sugar
- 2 large eggs
- 2 teaspoons vanilla extract
- 1/2 cup milk
For the Custard Filling:
- 1 cup whole milk
- 3 large egg yolks
- 1/3 cup granulated sugar
- 2 tablespoons cornstarch
- 1 teaspoon vanilla extract
For the Chocolate Ganache:
- 1 cup semi-sweet chocolate chips
- 1/2 cup heavy cream
Instructions
1. Prepare the Cupcakes:
- Preheat your oven to 350°F (175°C) and line a muffin tin with paper liners.
- In a medium bowl, whisk together the flour, baking powder, and salt. Set aside.
- In a large bowl, cream together the softened butter and granulated sugar until light and fluffy.
- Beat in the eggs one at a time, mixing well after each addition.
- Add the vanilla extract and mix until combined.
- Gradually add the dry ingredients to the butter mixture, alternating with the milk, beginning and ending with the dry ingredients. Mix until just combined.
- Divide the batter evenly among the muffin cups, filling each about two-thirds full.
- Bake in the preheated oven for 18-20 minutes, or until a toothpick inserted into the center comes out clean.
- Allow the cupcakes to cool completely on a wire rack before filling and frosting.
2. Make the Custard Filling:
- In a medium saucepan, heat the milk over medium heat until it begins to steam, but do not let it boil.
- In a separate bowl, whisk together the egg yolks, granulated sugar, and cornstarch until well combined.
- Slowly pour the hot milk into the egg mixture, whisking constantly to temper the eggs.
- Return the mixture to the saucepan and cook over medium heat, stirring constantly, until it thickens and comes to a gentle boil. This should take about 2-3 minutes.
- Remove from heat and stir in the vanilla extract.
- Transfer the custard to a bowl, cover with plastic wrap (press the wrap directly onto the surface of the custard to prevent a skin from forming), and refrigerate until completely chilled and set.
3. Prepare the Chocolate Ganache:
- In a small saucepan, heat the heavy cream over medium heat until it begins to simmer.
- Remove from heat and add the chocolate chips. Let sit for 1-2 minutes to allow the chocolate to melt.
- Stir until the ganache is smooth and glossy. Allow it to cool slightly before using.
4. Assemble the Cupcakes:
- Once the cupcakes are completely cooled, use a small knife or cupcake corer to cut a small hole in the center of each cupcake.
- Spoon or pipe the chilled custard filling into the hole, filling it generously.
- Spoon or pipe the chocolate ganache over the top of each cupcake, spreading it to cover the custard and create a smooth finish.
5. Serve and Enjoy:
- Allow the ganache to set before serving. This will take about 30 minutes at room temperature or can be sped up by placing the cupcakes in the refrigerator.
- Garnish with additional chocolate shavings or a sprinkle of powdered sugar if desired.
Tips for Perfect Boston Cream Cupcakes
- Chill the Custard: Ensure the custard is completely chilled before filling the cupcakes. This helps it maintain its texture and makes filling easier.
- Ganache Consistency: If the ganache becomes too thick as it cools, gently reheat it over a double boiler or in the microwave in short bursts to loosen it up before applying.
- Cupcake Storage: Store the filled and frosted cupcakes in an airtight container in the refrigerator. They are best enjoyed within 2-3 days.
These Boston Cream Cupcakes are a delightful treat that brings together a soft, buttery cupcake, a creamy custard filling, and a rich chocolate ganache. Perfect for special occasions or just a sweet indulgence, these cupcakes are sure to impress with their classic flavors and elegant presentation. Enjoy the blend of textures and flavors in every bite of this delicious dessert!
