Ingredients

• 2 cups All-purpose flour
• 2 teaspoons Baking powder
• 0.5 teaspoons Salt
• 0.5 cups Unsalted butter (softened)
• 1.5 cups Granulated sugar
• 3 Eggs
• 2 teaspoons Vanilla extract
• 1 cups Whole milk
• 4 Egg yolks
• 0.5 cups Granulated sugar (for pastry cream)
• 3 tablespoons Cornstarch
• 2 cups Whole milk (for pastry cream)
• 2 tablespoons Unsalted butter (for pastry cream)
• 1 teaspoon Vanilla extract (for pastry cream)
• 8 ounces Bittersweet chocolate
• 1 cup Heavy cream
• 2 tablespoons Unsalted butter (for ganache)

Directions

Step 1

Preheat the oven to 350°F (175°C) and prepare two 9-inch round cake pans by greasing and lining them with parchment paper.

Step 2

In a medium bowl, whisk together the flour, baking powder, and salt. Set aside.

Step 3

In a large mixing bowl, cream the softened butter and sugar together until light and fluffy, about 3 minutes.

Step 4

Beat in the eggs one at a time, followed by the vanilla extract.

Step 5

Gradually alternate adding the dry ingredients and the milk to the wet ingredients, beginning and ending with the dry ingredients. Mix until just combined.

Step 6

Divide the batter evenly between the two prepared pans and smooth the tops.

Step 7

Bake in the preheated oven for 25-30 minutes or until a toothpick inserted into the center comes out clean.

Step 8

Allow the cakes to cool in the pans for 10 minutes before transferring them to a wire rack to cool completely.

Step 9

To make the pastry cream, whisk together the egg yolks, sugar, and cornstarch in a medium bowl until smooth.

Step 10

In a saucepan, heat the milk over medium heat until it just starts to simmer. Slowly pour half of the hot milk into the egg yolk mixture while whisking constantly, then return the mixture to the saucepan.

Step 11

Cook over medium heat, whisking constantly, until the mixture thickens and begins to bubble. Remove from heat and stir in the butter and vanilla extract.

Step 12

Pour the pastry cream into a bowl, cover with plastic wrap (pressing it directly against the surface to prevent a skin from forming), and chill in the refrigerator for at least 2 hours.

Step 13

To make the ganache, place the bittersweet chocolate, heavy cream, and butter into a heatproof bowl set over a saucepan of simmering water. Stir until the chocolate is completely melted and the mixture is smooth. Remove from heat and let cool slightly.

Step 14

To assemble the cake, place one layer of sponge cake on a serving platter and spread the chilled pastry cream evenly over the top.

Step 15

Place the second cake layer on top and pour the ganache over the entire cake, allowing it to drizzle down the sides.

Step 16

Chill the assembled cake in the refrigerator for 30 minutes before serving to allow the ganache to set.

Step 17

Slice and enjoy your Boston Cream Cake Supreme!
