Ingredients

Scale

For the Cake Layers:

  • 1 ½ cups cake flour
  • 1 cup granulated sugar
  • 1 ½ teaspoons baking powder
  • ½ teaspoon salt
  • 3 large eggs (room temperature)
  • ½ cup milk (room temperature)
  • 6 tablespoons unsalted butter (melted and cooled)
  • 1 teaspoon vanilla extract or seeds from 1 vanilla bean

For the Vanilla Custard Filling:

  • 2 cups whole milk
  • 4 large egg yolks
  • ½ cup granulated sugar
  • 3 tablespoons cornstarch
  • 1 teaspoon vanilla extract or seeds from 1 vanilla bean
  • 2 tablespoons unsalted butter

For the Chocolate Ganache:

  • 1 cup heavy cream
  • 8 ounces dark chocolate (chopped or in chips)

Optional Additions:

  • ½ teaspoon almond or coffee extract (for added flavor)
  • Fresh fruit (strawberries, blueberries, or bananas for garnish)

Instructions

  1. Prepare the Cake Batter: In a large bowl, whisk together the cake flour, granulated sugar, baking powder, and salt. In a separate bowl, beat the eggs, then add milk, melted butter, and vanilla extract or vanilla bean seeds. Gradually combine the wet ingredients with the dry ingredients until the batter is smooth and well mixed.
  2. Bake the Cake Layers: Preheat the oven to 350°F (175°C). Grease two 8-inch round cake pans and evenly divide the batter between them. Bake for 25-30 minutes or until a toothpick inserted into the center comes out clean. Remove from oven and let the cakes cool completely in the pans.
  3. Make the Vanilla Custard Filling: In a medium saucepan, heat the whole milk until just warm but not boiling. In a separate bowl, whisk together the egg yolks, sugar, and cornstarch until pale and thick. Slowly pour the warm milk into the egg mixture while whisking constantly to temper the eggs and prevent curdling. Return the mixture to the saucepan and cook over medium heat, stirring constantly until thickened and smooth. Remove from heat, stir in butter and vanilla extract or vanilla bean seeds, and let cool slightly.
  4. Prepare the Chocolate Ganache: Heat the heavy cream in a small saucepan until it begins to bubble around the edges. Pour the hot cream over the chopped dark chocolate in a heatproof bowl. Let sit for 1-2 minutes to allow the chocolate to melt, then stir gently until the ganache is smooth, silky, and glossy.
  5. Assemble the Boston Cream Pie: Place one cooled cake layer on a serving plate. Spread the custard filling evenly over the top. Place the second cake layer on top of the custard, gently pressing down. Pour the chocolate ganache over the top layer, allowing it to drip down the sides. Refrigerate the assembled cake for at least 1 hour to let the ganache set before serving.
  6. Serve and Garnish: Optionally garnish with fresh fruit such as strawberries, blueberries, or banana slices for added color and flavor. Slice and enjoy your classic Boston Cream Pie!

Notes

  • Ensure the cake layers are completely cool before assembling to prevent the custard from melting.
  • Slowly temper the egg yolks with warm milk to avoid scrambling the eggs in the custard.
  • Use high-quality dark chocolate for the ganache for best flavor and shine.
  • Refrigerate the finished pie for at least 1 hour to allow the ganache to set perfectly.
  • Optional extracts like almond or coffee can be added to the custard or ganache to customize the flavor.
