063Boston Cream Pie Cupcake            Printer-Friendly Recipe

From: Spoonful of Sugar
Makes: 24 cupcakes

Ingredients

Cupcake

Box of yellow cake mix, baked according to package directions (mine called for 1/3 cup oil, 3 eggs, and 1 cup of water) **or use your favorite yellow cupcake recipe

Pastry Cream Filling

2 cups whole milk
4 egg yolks
1/3 cup sugar
Pinch of salt
1/4 cup cornstarch
2 tablespoons butter
1 teaspoon vanilla

Chocolate Ganache Topping

1/2 cup heavy cream
4 tablespoons butter
6 oz. semi-sweet chocolate

Directions

Cupcakes

Make cupcakes according to package directions. Allow the cupcakes to cool completely.

Pastry Cream Filling

Heat milk in a saucepan until it begins to simmer. While the milk is heating, whisk the egg yolks, sugar, and salt in a bowl. Whisk in the cornstarch and continue whisking until thick and yellow. When the milk has come to a simmer, slowly (and I mean sloooooowly, to prevent the eggs from scrambling) drizzle the milk into the egg yolk mixture. Pour the mixture into the saucepan and heat, whisking constantly, until thick and glossy. This will take a couple minutes and it is very important that you whisk the entire time.

Remove from heat and stir in the butter and vanilla. Stir until the butter is melted. Pour the mixture into a clean bowl and place plastic wrap directly on top of the cream to cover. Refrigerate for at least 2 hours (up to 24 hours).

Ganache Topping

Place a bowl on top of a saucepan of boiling water. To the bowl, add all of the ganache ingredients. Stir occasionally until completely melted and smooth. (I made the ganache topping immediately before assembling the cupcakes.)

To assemble the Cupcakes

Place pastry cream in a pastry bag fitted with a round tip. Using the tip, gently press into the cooled cupcakes and squeeze in some filling. Do this slowly at first to gauge how much pastry cream is needed to fill each cupcake (the cupcake will start to split if there is too much cream in it). Continue until all of the cupcakes are filled. Now dunk the top of each cupcake in the ganache. Allow the ganache topping to set up a bit before serving. Store leftover cupcakes in refrigerator. Enjoy!
