A classic Boston Cream Pie with a tender, buttery sponge cake, a rich vanilla bean pastry cream, and a glossy chocolate ganache. This indulgent dessert balances silky custard with a light, airy cake and a dark chocolate finish.

Ingredients

  • For the Cake: 1 cup (125g) all-purpose flour
  • For the Cake: 1 teaspoon baking powder
  • For the Cake: 1/4 teaspoon kosher salt
  • For the Cake: 2 large eggs, at room temperature
  • For the Cake: 1/2 cup (100g) granulated sugar
  • For the Cake: 1/4 cup (60ml) whole milk, at room temperature
  • For the Cake: 1/4 cup (56g) unsalted butter, melted and slightly cooled
  • For the Cake: 1 teaspoon vanilla extract
  • For the Pastry Cream: 1 cup (240ml) whole milk
  • For the Pastry Cream: 1/4 cup (50g) granulated sugar
  • For the Pastry Cream: 2 large egg yolks
  • For the Pastry Cream: 1 1/2 tablespoons cornstarch
  • For the Pastry Cream: 1/2 teaspoon vanilla bean paste or 1 teaspoon vanilla extract
  • For the Ganache: 1/2 cup (120ml) heavy cream
  • For the Ganache: 3 ounces (85g) semisweet chocolate, finely chopped

Instructions

  1. Preheat your oven to 350°F (177°C). Grease an 8-inch round cake pan with butter or nonstick spray and line the bottom with parchment paper for easy removal.
  2. In a medium bowl, whisk together the flour, baking powder, and salt. Sifting is not necessary, but whisking ensures even distribution of the leavening.
  3. In a large mixing bowl, beat the eggs and granulated sugar with an electric mixer on medium-high speed for 3-4 minutes until pale, thick, and ribbon-like when the beaters are lifted. This aerates the batter for a light sponge.
  4. Reduce the mixer to low speed and gradually add the milk, melted butter, and vanilla extract. Mix just until combined; overmixing will deflate the eggs and result in a dense cake.
  5. Fold the dry ingredients into the wet mixture using a rubber spatula. Fold gently until no streaks of flour remain, scraping the bottom and sides of the bowl. Take care not to overmix—the batter should be smooth but not beaten.
  6. Pour the batter into the prepared pan and spread it into an even layer. Bake for 22-25 minutes, or until the top is golden and a toothpick inserted into the center comes out clean with a few moist crumbs.
  7. Let the cake cool in the pan on a wire rack for 10 minutes, then carefully invert onto the rack to remove the parchment. Cool completely to room temperature before assembling—about 30 minutes.
  8. While the cake cools, make the pastry cream. In a medium saucepan, heat the milk over medium heat until steaming but not boiling—small bubbles will form around the edges. Remove from heat.
  9. In a separate heatproof bowl, whisk together the sugar, egg yolks, and cornstarch until pale and thick—about 2 minutes. This mixture will be thick but should be smooth.
  10. Slowly whisk about 1/4 cup of the hot milk into the egg mixture to temper it, then pour the egg mixture back into the saucepan with the remaining milk. Cook over medium-low heat, stirring constantly with a whisk, until the mixture thickens and just begins to bubble—about 3-4 minutes. It should be thick enough to coat the back of a spoon.
  11. Remove from heat and stir in the vanilla bean paste or extract. Transfer the pastry cream to a clean bowl, cover with plastic wrap directly on the surface to prevent a skin, and refrigerate until fully chilled, at least 2 hours or up to 2 days.
  12. When ready to assemble, make the ganache. Place the chopped chocolate in a small heatproof bowl. Heat the heavy cream in a small saucepan over medium heat until it just comes to a simmer—edges will bubble and steam rises. Pour the hot cream over the chocolate and let sit for 2 minutes without stirring.
  13. Whisk the chocolate and cream together until smooth and glossy. If any lumps remain, place the bowl over a pan of simmering water for a minute, stirring, to fully melt. Let the ganache cool slightly for 5-10 minutes until it thickens enough to spread but is still pourable.
  14. Using a serrated knife, slice the cooled cake horizontally into two even layers. Spread the chilled pastry cream evenly over the bottom layer, leaving a small border around the edges. Place the top layer over the filling, then pour the ganache over the top, spreading it gently to the edges with an offset spatula. Refrigerate for 30 minutes to set the ganache before slicing and serving.

Notes

Storage: Store covered in the refrigerator for up to 3 days. The pastry cream and ganache are perishable. For best texture, assemble no more than 6 hours before serving. Freezing: The cake layers (without filling or ganache) can be wrapped tightly and frozen for up to 2 months. Thaw overnight in the refrigerator. To reheat individual slices, microwave at 30% power for 15-20 seconds just to take off the chill, but note the pastry cream will soften. Alternatively, let sit at room temperature for 15 minutes before serving.
