Boston Cream Pie

Boston Cream Pie is the kind of dessert that never goes out of style. With its soft, buttery sponge cake, smooth vanilla pastry cream, and rich chocolate ganache, it’s a classic that’s just as delicious today as it was over a century ago. Surprisingly, despite the name, it’s actually a cake, not a pie! It was first created in the 1850s at the Parker House Hotel in Boston, where bakers layered custard between delicate sponge cake and topped it with glossy chocolate. Over time, it became so iconic that it was named Massachusetts’ official state dessert!

Now, making a homemade Boston Cream Pie might seem fancy, but don’t worry—it’s totally doable! The cake is light yet sturdy, the pastry cream is rich and silky, and the ganache ties it all together with chocolatey perfection. Whether you’re baking for a celebration or just because, this recipe will steal the show. So, let’s get baking and create a dessert that’s as fun to make as it is to eat! You’re going to love every bite!

INGREDIENTS

Cake:
1 2/3 cup all-purpose flour
1 1/2 tsp baking powder
1/4 tsp baking soda
1/2 tsp salt
1/2 cup unsalted butter, softened
3/4 cup granulated sugar
2 large eggs, room temp
1 1/2 tsp vanilla extract
3/4 cup whole milk, room temp

Pastry Cream Filling:
1 1/2 cups whole milk
1/3 cup granulated sugar
3 tbsp cornstarch
3 large egg yolks
2 tbsp unsalted butter
1 1/2 tsp vanilla extract
1/8 tsp salt

Chocolate Ganache:
3/4 cup semi-sweet chocolate chips (or chopped dark chocolate)
1/2 cup heavy cream
1/2 tbsp unsalted butter
1/2 tsp vanilla extract

INSTRUCTIONS

1. Preheat and prepare:
Preheat oven to 350°F (175°C). Grease and flour two 8-inch round cake pans and line bottoms with parchment.

2. Mix dry ingredients:
In a bowl, whisk together flour, baking powder, baking soda, and salt. Set aside.

3. Cream butter and build batter:
Beat butter and sugar on medium-high speed for 2–3 minutes until light and fluffy. Add eggs one at a time, then mix in vanilla. Add the flour mixture in three additions, alternating with milk in two additions (begin and end with flour). Mix just until combined.

4. Bake the cakes:
Divide batter evenly between pans and bake for 22–25 minutes, until a toothpick inserted comes out clean. Cool for 10 minutes, then transfer to a wire rack and cool completely.

5. Make pastry cream:
Heat milk in a saucepan until steaming. In a bowl, whisk sugar, cornstarch, salt, and egg yolks until pale and thick. Slowly whisk hot milk into the egg mixture, then return everything to the saucepan.

6. Cook and chill pastry cream:
Cook over medium heat, stirring constantly, until bubbling, thick, and smooth, about 3–4 minutes. Remove from heat, stir in butter and vanilla, then transfer to a bowl. Cover with plastic wrap touching the surface and chill for 30–40 minutes.

7. Make ganache:
Heat cream until hot but not boiling, then pour over chocolate. Let sit 2 minutes, stir until smooth, and mix in butter and vanilla. Cool slightly until thick but still pourable.

8. Assemble the cake:
Place one cake layer on a serving plate and spread pastry cream evenly over the top. Add the second cake layer and gently press down.

9. Add ganache and set:
Pour ganache over the center, letting it drip naturally over the sides. Let sit for 30 minutes before slicing.

HELPFUL TIPS TO PERFECT THIS RECIPE

• Room Temperature Ingredients: Ensure butter, eggs, and milk are at room temp for a smoother batter and even bake.
• Don’t Overmix: Mixing just until combined keeps the cake soft and tender.
• Chill the Cream Fully: Properly chilled pastry cream gives clean layers and better structure.
• Perfect Ganache Texture: Let ganache cool slightly before pouring so it thickens just enough for controlled drips.
• Level if Needed: If cake layers dome slightly, trim for a more even finish.
