Ingredients
  

For the Cupcakes:

  • 1 ½ cups all-purpose flour
  • 1 ½ tsp baking powder
  • ¼ tsp salt
  • ½ cup unsalted butter, softened
  • ¾ cup granulated sugar
  • 2 large eggs
  • 1 ½ tsp vanilla extract
  • ½ cup whole milk

For the Pastry Cream Filling:

  • 1 cup whole milk
  • ½ cup heavy cream
  • 3 large egg yolks
  • ¼ cup granulated sugar
  • 2 tbsp cornstarch
  • 1 tbsp unsalted butter
  • 1 tsp vanilla extract

For the Chocolate Ganache:

  • ½ cup heavy cream
  • 4 oz semi-sweet chocolate, chopped
  • 1 tbsp unsalted butter

Instructions
 

Step 1: Prepare the Cupcake Batter

  • Preheat the oven to 350°F (175°C) and line a muffin tin with cupcake liners.
  • In a bowl, whisk together flour, baking powder, and salt. Set aside.
  • In another bowl, beat butter and sugar until light and fluffy.
  • Add eggs one at a time, then mix in vanilla extract.
  • Gradually add the dry ingredients, alternating with milk, until combined.

Step 2: Bake the Cupcakes

  • Divide the batter evenly among the cupcake liners, filling each about ⅔ full.
  • Bake for 18-20 minutes, or until a toothpick inserted in the center comes out clean.
  • Let the cupcakes cool in the pan for 5 minutes, then transfer them to a wire rack to cool completely.

Step 3: Make the Pastry Cream Filling

  • Heat milk and heavy cream over medium heat until steaming but not boiling.
  • In a separate bowl, whisk together egg yolks, sugar, and cornstarch.
  • Slowly pour the hot milk into the egg mixture while whisking continuously.
  • Return the mixture to the saucepan and cook, stirring constantly, until thickened.
  • Remove from heat and stir in butter and vanilla extract.
  • Let the cream cool, then refrigerate for at least 30 minutes.

Step 4: Fill the Cupcakes

  • Use a sharp knife or cupcake corer to cut a small hole in the center of each cupcake.
  • Fill each hole with about 1-2 teaspoons of the chilled pastry cream.
  • Gently replace the cut-out pieces on top of the filling (optional).

Step 5: Make the Chocolate Ganache

  • Heat heavy cream in a small saucepan until steaming but not boiling.
  • Pour over chopped chocolate and let sit for 1-2 minutes.
  • Stir until smooth, then add butter for extra shine.

Step 6: Top with Ganache and Serve

  • Spoon or drizzle the ganache over the filled cupcakes.
  • Let the ganache set for about 10-15 minutes before serving.
  • Enjoy your homemade Boston Cream Pie Cupcakes!

Notes

✔ For the best texture, ensure the cupcakes are fully cooled before filling.
✔ To prevent soggy cupcakes, chill the pastry cream before use.
✔ For a glossy ganache, add a teaspoon of corn syrup or extra butter.
✔ Want to save time? Use store-bought vanilla pudding instead of homemade pastry cream.
