- In a bowl, beat the eggs and sugar together until pale and thick. Add vanilla.
- Sift together flour and baking powder, then gently fold into the egg mixture.
- Warm the milk and melted butter together, then stir into the batter.
- Divide the batter evenly between pans and bake for 20–25 minutes, or until golden and a toothpick comes out clean. Cool completely.
- Make the Pastry Cream: Heat the milk in a saucepan until steaming.
- In another bowl, whisk egg yolks, sugar, and cornstarch until smooth.
- Slowly pour the hot milk into the egg mixture, whisking constantly.
- Return the mixture to the saucepan and cook over medium heat until thickened. Stir in vanilla and butter. Chill until set.
- Assemble: Place one cake layer on a serving plate. Spread the chilled pastry cream over the top. Place the second layer over the cream.
- Make the Chocolate Glaze: Heat the cream until just simmering, then pour over the chopped chocolate. Let sit 1 minute, then stir until smooth.

🌍 A Sweet Slice of Boston’s History
Boston Cream Pie traces its roots back to the 1850s, when a French-trained chef at Boston’s Parker House Hotel dreamed up this dessert.
Combining tender sponge cake, rich custard, and a glossy chocolate glaze, it quickly became an American favorite — so much so that it’s now the official state dessert of Massachusetts.
Despite being called a “pie,” this layered creation was baked in pie tins at the time, giving it a name that stuck for over a century.
🍽️ Best Ways to Serve Boston Cream Pie
Boston Cream Pie is best served chilled, allowing the cream to set and the flavors to meld beautifully.
For an extra touch, garnish with a few chocolate curls or a dusting of powdered sugar before slicing.
❓ FAQs About Boston Cream Pie
Why is it called a pie if it’s a cake?

Can I make it ahead of time?
Yes! Assemble the cake up to one day ahead and refrigerate. Add the glaze just before serving if you want the freshest shine.

Semi-sweet or bittersweet chocolate works beautifully — choose something with about 60% cacao for perfect flavor.
