Ingredients

Scale

For the Cake:

  • 1 1/2 cups all-purpose flour
  • 1 cup granulated sugar
  • 1/2 cup unsalted butter, softened
  • 2 large eggs
  • 3/4 cup milk
  • 1 1/2 tsp baking powder
  • 1 tsp vanilla extract
  • 1/4 tsp salt

For the Custard Filling:

  • 1 cup whole milk
  • 1/4 cup granulated sugar
  • 1 tbsp cornstarch
  • 2 egg yolks
  • 1 tsp vanilla extract
  • 1 tbsp unsalted butter

For the Chocolate Ganache:

  • 1/2 cup heavy cream
  • 1/2 cup semisweet chocolate chips

Instructions

  1. Prepare cake pans and preheat oven: Preheat your oven to 350°F (175°C) and grease and flour two 8-inch round cake pans to ensure the cakes do not stick.
  2. Create cake batter: Beat together the softened butter and sugar until the mixture is light and fluffy. Add the eggs one at a time, mixing well after each addition, then stir in the vanilla extract.
  3. Combine dry and wet ingredients: In a separate bowl, whisk together the flour, baking powder, and salt. Gradually add the dry ingredients alternately with the milk to the butter mixture, stirring gently until the batter is smooth and well combined.
  4. Bake the cakes: Divide the batter evenly between the prepared pans. Bake in the preheated oven for 25 to 30 minutes or until a toothpick inserted into the center comes out clean. Allow the cakes to cool completely before assembling.
  5. Prepare the custard filling: Heat the whole milk gently in a saucepan until warm. In a separate bowl, whisk together sugar, cornstarch, and egg yolks until smooth. Gradually temper the egg mixture by slowly adding the warm milk while whisking continuously. Return the mixture to the saucepan and cook over medium heat, stirring constantly, until it thickens. Remove from heat and stir in the vanilla extract and butter. Let the custard cool completely.
  6. Make the chocolate ganache: Heat the heavy cream in a small saucepan until hot but not boiling. Pour the hot cream over the semisweet chocolate chips in a bowl. Let it sit for a minute, then stir until smooth and glossy.
  7. Assemble the Boston Cream Pie: Place one cake layer on a serving plate and spread the chilled custard evenly over it. Top with the second cake layer. Pour the chocolate ganache evenly over the top, allowing it to drip down the sides.
  8. Set and serve: Allow the assembled cake to set for at least 30 minutes before slicing to let the ganache firm up and flavors meld.

Notes

  • Ensure cakes are completely cooled before adding custard to prevent melting.
  • Use room temperature eggs and butter for best mixing results.
  • For a smoother custard, whisk continuously to avoid lumps during cooking.
  • Ganache can be poured warm but should be at room temperature when serving for best texture.
  • Store leftovers covered in the refrigerator and consume within 2 days for optimal freshness.
