Boston Cream Pie Cupcakes


Happy Pi(e) Day!

Any holiday that mandates a celebration with lots of food, especially dessert, is an a-okay holiday in my books.  Thankfully most holidays here center, or at least feature, lots and lots of food.  And while celebrating math is not something I support quite as much, I’ll celebrate Pi Day if it means I get to eat some more dessert.

While Boston Cream Pie isn’t technically a pie, it has the word “pie” in the title, it’s a dessert, and it’s delicious- so I say it works for Pi day.  And what’s even better is putting Boston Cream Pie in individual-sized adorable cupcake form.  Make sure to have some type of pie today to celebrate!

For the Pastry Cream:
1 1/3 cups heavy cream
3 egg yolks
1/3 cup granulated sugar
1/2 teaspoon salt
4 teaspoons cornstarch
2 tablespoons butter, cut into 2 pieces
1 1/2 teaspoons vanilla extract

For the Cupcakes:
1 3/4 cup all purpose flour
1 cup granulated sugar
1 1/2 teaspoons baking powder
3/4 teaspoon salt
12 tablespoons butter, room temperature & in 12 pieces
3 eggs, room temperature
3/4 cup milk, room temperature
1 1/2 teaspoons vanilla extract

For the Chocolate Icing:
4 tablespoons butter
3 tablespoons cocoa powder
Pinch of salt
2 tablespoons milk
1/2 cup powdered sugar
1/2 teaspoon vanilla extract


For the Pastry Cream:

Place cream in a saucepan over medium heat. Bring to a simmer. Meanwhile, beat egg yolks, sugar, and salt in a bowl. Whisk in cornstarch until pale yellow and thick.

Slowly whisk the heavy cream into the egg mixture to temper. Return to the saucepan. Cook over medium heat, whisking constantly, until the pastry cream thickens, about 2 minutes. Remove from heat and whisk in butter and vanilla. Pour into a bowl, wrap tightly with plastic wrap (to prevent a skin from forming) and chill for at least 2 hours, preferably overnight.

For the Cupcakes:

Preheat the oven to 350°F. Line a 12 cup cupcake pan with cupcake liners.

Whisk flour, sugar, baking powder, and salt together in a large bowl. Using a stand mixrer or hand mixer, beat butter into flour mixture one piece at a time. Beat until mixture forms moist crumbs, 1-3 minutes. Beat in eggs. Beat in milk and vanilla. Increase speed and mix until smooth, light, and fluffy, about 2-3 minutes.

Pour batter into cupcake tins, filling each cup about 3/4 full. Bake for 18-20 minutes, until a toothpick comes out clean. Cool completely.

Use a pairing knife to cut a whole in each muffin, removing excess cake. Fill each cupcake with pastry cream and place cupcake top back on top.

For the Chocolate Frosting:

In a saucepan combine butter, cocoa powder, salt, and milk. Cook over medium heat, stirring occasionally, until butter in melted. Whisk in powdered sugar. Remove from heat and stir in vanilla. Let sit for approximately 10 minutes. Pour frosting on top of cupcakes. Let set for at least 30 minutes.

Makes 12 cupcakes.
