A Slice of History

The Boston Cream Pie’s journey began at the Parker House Hotel in Boston, Massachusetts, in the mid-19th century. Contrary to what its name might suggest, this dessert is categorically a cake. The “pie” moniker is a nod to a time when pies and cakes were often baked in the same pans, and the terms were used interchangeably. It was in this historic setting that French pastry chef Sanzian conceived what was then known as a “Chocolate Cream Pie,” which quickly became a sensation. In 1996, the Boston Cream Pie was proclaimed the official dessert of Massachusetts, cementing its status as an iconic American treat.

The Anatomy of a Classic

At its core, the Boston Cream Pie consists of three essential components: the sponge cake, the custard filling, and the chocolate glaze. Each layer contributes to the dessert’s overall complexity and indulgence. The sponge cake provides a light, airy foundation, the custard filling offers a rich, creamy contrast, and the chocolate glaze adds a luxurious finish that complements the other elements perfectly.

The Sponge Cake

The sponge cake layer is the cornerstone of the Boston Cream Pie. Its light, airy texture is achieved through careful preparation and the right balance of ingredients. Unlike denser cakes, the sponge relies on whipped eggs to incorporate air and achieve its signature fluffiness.

The Custard Filling

The custard filling is what truly sets the Boston Cream Pie apart. Made from a blend of milk, eggs, sugar, and vanilla, this creamy, velvety layer nestles between the sponge cakes, infusing the dessert with richness and depth.

The Chocolate Glaze

Completing the trifecta is the chocolate glaze—a smooth, glossy coating that crowns the dessert. The glaze not only adds visual appeal but also introduces a decadent chocolate flavor that perfectly balances the sweetness of the custard and the lightness of the cake.

Ingredients

Sponge Cake

• 1 cup (120g) all-purpose flour
• 1 cup (200g) granulated sugar
• 4 large eggs
• 1/2 cup (120ml) whole milk
• 1/4 cup (60ml) unsalted butter
• 2 tsp (10ml) vanilla extract
• 1 1/2 tsp (7.5ml) baking powder
• 1/4 tsp (1.25ml) salt

Custard Filling

• 2 cups (480ml) whole milk
• 1/2 cup (100g) granulated sugar
• 4 large egg yolks
• 1/4 cup (30g) cornstarch
• 2 tsp (10ml) vanilla extract
• 1/4 tsp (1.25ml) salt
• 2 tbsp (30ml) unsalted butter

Chocolate Glaze

• 1/2 cup (120ml) heavy cream
• 4 oz (115g) semisweet chocolate, chopped
• 2 tbsp (30ml) light corn syrup
• 1/4 tsp (1.25ml) vanilla extract

Preparation

Sponge Cake

1. Preheat your oven to 350°F (175°C). Grease and flour two 9-inch round cake pans.
2. In a small saucepan, heat the milk and butter until the butter melts. Remove from heat and add vanilla. Set aside.
3. In a large mixing bowl, beat eggs and sugar until light and fluffy. Gradually add the dry ingredients, alternating with the milk mixture, starting and ending with flour.
4. Divide the batter evenly between the prepared pans. Bake for 18-20 minutes, or until a toothpick inserted into the center comes out clean. Cool on a wire rack.

Custard Filling

1. In a medium saucepan, heat the milk over medium heat until it just begins to simmer. In a separate bowl, whisk together egg yolks, sugar, cornstarch, and salt.
2. Gradually temper the egg mixture by adding the hot milk in a slow, steady stream, whisking constantly. Return the mixture to the saucepan and cook over medium heat, stirring constantly, until thickened.
3. Remove from heat, stir in vanilla and butter until smooth. Cover with plastic wrap, pressing it directly onto the surface of the custard to prevent a skin from forming. Chill in the refrigerator.

Chocolate Glaze

1. Heat the heavy cream in a small saucepan over medium heat until it begins to simmer. Remove from heat and add the chopped chocolate, letting it sit for a minute before stirring until smooth. Stir in corn syrup and vanilla. Let cool slightly before using.

Assembly

1. Place one layer of sponge cake on a serving plate. Spread the custard evenly over the top. Top with the second layer of cake.
2. Pour the chocolate glaze over the cake, using a spatula to spread it evenly over the top and allowing some to drip down the sides.
3. Chill the cake in the refrigerator for at least an hour to set the glaze before serving.
