Ingredients

Scale

Cake

  • 1 cup cake flour
  • 3/4 cup sugar
  • 2 large eggs
  • 1/4 cup unsalted butter, melted
  • 1/2 cup milk
  • 1 vanilla bean, split and seeds scraped

Custard Filling

  • 2 cups heavy cream
  • 1 vanilla bean, split and seeds scraped
  • 1/2 cup sugar
  • 4 large egg yolks
  • 2 tablespoons cornstarch

Chocolate Ganache

  • 4 oz dark chocolate, chopped
  • 1/2 cup heavy cream

Instructions

  1. Prepare the Cake: Preheat the oven to 350°F (175°C). In a mixing bowl, whisk together the cake flour and sugar. Add the eggs, melted butter, milk, and vanilla bean seeds. Mix until smooth and pour the batter evenly into two greased 8-inch round cake pans. Bake for 25-30 minutes or until a toothpick inserted into the center comes out clean. Cool completely.
  2. Make the Vanilla Custard: In a saucepan, heat 1 cup of heavy cream with the vanilla bean seeds and pod until it just begins to boil. Remove from heat and let infuse for 10 minutes. In a separate bowl, whisk the egg yolks, sugar, and cornstarch together. Slowly pour the hot cream through a strainer into the yolk mixture while whisking constantly to temper. Return the mixture to the saucepan and cook over medium heat, stirring constantly, until thickened. Remove the vanilla pod and transfer to a bowl to cool completely.
  3. Prepare the Ganache: Heat the remaining 1/2 cup heavy cream in a small saucepan until it simmers. Pour the hot cream over the chopped dark chocolate in a heatproof bowl. Let sit for 2 minutes, then stir until smooth and glossy. Allow to cool slightly until it thickens but is still pourable.
  4. Assemble the Boston Cream Pie: Place one cake layer on a serving plate. Spread the chilled vanilla custard evenly over the top. Carefully place the second cake layer on top. Pour the chocolate ganache over the top layer, allowing it to drip down the sides. Chill the cake for at least 1 hour before serving to set the ganache.

Notes

  • Use cake flour for a lighter texture in the cake layers.
  • Ensure the custard is fully cooled before assembling to prevent melting.
  • Chill the assembled cake to allow the ganache to set properly.
  • Vanilla bean can be substituted with 1 teaspoon of pure vanilla extract if not available.
  • Use high-quality dark chocolate for a rich ganache flavor.
