Boston cream pie is Massachusetts' official state dessert—a deceptively simple cake filled with vanilla custard and glazed with chocolate. It's been served at the Omni Parker House since 1856.
This is the kind of recipe that defines American home cooking at its best — straightforward, satisfying, and built on flavors that everyone loves.
This recipe represents the best of American home cooking — unpretentious, generous, and built to satisfy. Boston Cream Pie is the kind of dish that brings people to the table and keeps them coming back for seconds. It draws on the diverse culinary traditions that have shaped American food culture, combining familiar flavors with techniques that produce consistently excellent results.
Successful baking comes down to precision and patience. Measure carefully, follow the order of operations, and trust the recipe. The oven does most of the work — your job is to set it up for success with properly mixed ingredients, the right temperature, and restraint (no peeking during the first two-thirds of baking time).
Ingredients
Instructions
- 1
Beat eggs and sugar until thick and pale, about 5 minutes. Fold in flour and melted butter. Bake in a greased 9-inch round pan at 350°F for 22-25 minutes. Cool and split horizontally.
- 2
Make pastry cream: whisk yolks, 1/4 cup sugar, and cornstarch. Heat milk to a simmer, temper into the yolk mixture, return to the pot, and cook until thick.
- 3
Strain pastry cream, cover with plastic wrap directly on the surface, and refrigerate until cold.
- 4
Spread pastry cream over the bottom cake layer, about 1 inch thick. Place the top layer over it.
- 5
Make ganache: heat cream until simmering, pour over chopped chocolate, stir until smooth. Pour over the cake, letting it drip down the sides.

Tips & Storage
Pro Tips
Press plastic wrap directly onto the pastry cream surface to prevent a skin from forming.
Let the ganache cool for 5 minutes before pouring so it coats the cake instead of running off.
Measure baking ingredients by weight when possible. Baking is chemistry, and precision matters more than in any other type of cooking.
Bring butter, eggs, and dairy to room temperature before mixing. Cold ingredients do not emulsify properly and can produce tough, uneven results.
Storage
Refrigerate up to 3 days. The pastry cream filling needs to stay cold.
Reheating
Serve cold or let it sit at room temperature for 15 minutes before serving.

Frequently Asked Questions
- Why is it called a pie?
- In the 1800s, cakes and pies were baked in the same pans, and the terms were used interchangeably.
- Can I use instant pudding?
- Yes—vanilla pudding made thick with less milk is a quick substitute for pastry cream.
- Can I substitute the sugar?
- In baking, sugar does more than sweeten — it affects texture, browning, and moisture. You can reduce by up to 25% without major issues, but substituting entirely often changes the result significantly.
- Why did my recipe not turn out right?
- The most common causes are inaccurate measuring, incorrect oven temperature (use an oven thermometer), or substituting ingredients. Baking is chemistry — precision matters more than in any other type of cooking.
