What Is a Boston Cream Cake?
The Origin and History of Boston Cream Cake
Boston cream cake owes its origins to the famous Boston cream pie, which was invented in the 19th century at the Parker House Hotel in Boston. The original dessert combined sponge cake with custard filling, topped with chocolate glaze. Over time, the “pie” evolved into a cake, offering a more structured dessert that’s easier to slice and serve.
Fun Fact: “Did you know that Boston cream pie is the official dessert of Massachusetts? 🍰”

Step-by-Step Instructions for Boston Cream Cake
Ready to create your own Boston cream cake? Here’s a detailed guide to making each component from scratch. Don’t worry—it’s easier than it looks, and the results are worth every step!
Preparing the Cake Base
- Ingredients:
- 2 1/2 cups all-purpose flour
- 2 1/2 tsp baking powder
- 1/2 tsp salt
- 1/2 cup unsalted butter, softened
- 1 1/2 cups granulated sugar
- 3 large eggs
- 1 cup whole milk
- 2 tsp vanilla extract
- Instructions:
- Preheat your oven to 350°F (175°C) and grease two 9-inch round cake pans.
- In a medium bowl, whisk together flour, baking powder, and salt. Set aside.
- Cream the butter and sugar until light and fluffy, about 3 minutes. Add eggs one at a time, beating well after each addition.
- Mix in vanilla extract.
- Alternate adding the dry ingredients and milk to the butter mixture, starting and ending with the dry ingredients. Mix just until combined.
- Divide the batter evenly between the prepared pans. Bake for 25-30 minutes, or until a toothpick inserted in the center comes out clean.
- Let the cakes cool in the pans for 10 minutes, then transfer to a wire rack to cool completely.
Pro Tip: “Use parchment paper circles in the pans for easy removal and perfectly smooth layers.”
Making the Custard Filling
- Ingredients:
- 2 cups whole milk
- 1/2 cup granulated sugar
- 1/4 cup cornstarch
- 4 large egg yolks
- 2 tsp vanilla extract
- Instructions:
- In a medium saucepan, heat the milk over medium heat until steaming but not boiling.
- In a separate bowl, whisk together sugar, cornstarch, and egg yolks until smooth.
- Slowly pour the hot milk into the egg mixture while whisking constantly to temper the eggs.
- Return the mixture to the saucepan and cook over medium heat, whisking continuously, until thickened (about 3-5 minutes).
- Remove from heat, stir in vanilla extract, and transfer to a bowl. Cover with plastic wrap directly on the surface to prevent a skin from forming. Refrigerate until cool.
Quick Fact: “Custard thickens as it cools, so don’t worry if it looks a little runny when warm.”
Assembling the Cake Like a Pro
- Level the Cakes: Use a serrated knife or cake leveler to trim the domed tops of each cake layer for an even surface.
- Add the Custard Filling: Place one cake layer on a serving plate. Spread the chilled custard filling evenly across the surface, leaving a slight border around the edges.
- Top with the Second Layer: Gently place the second cake layer on top, pressing lightly to secure it.
Pro Tip: “Chill the assembled cake for 30 minutes before adding the glaze to prevent the layers from sliding.”
Topping It Off with the Chocolate Glaze
- Ingredients:
- 1 cup heavy cream
- 8 oz semi-sweet chocolate chips
- 1 tbsp unsalted butter
- Instructions:
- Heat the heavy cream in a small saucepan over medium heat until just simmering.
- Pour the hot cream over the chocolate chips in a heatproof bowl. Let sit for 2 minutes, then stir until smooth. Add the butter and mix until glossy.
- Pour the glaze over the assembled cake, letting it drip down the sides for a beautiful finish. Use a spatula to spread it evenly if needed.
Fun Tip: “For a professional look, let the glaze set for about 15 minutes before serving.”
Common Variations of Boston Cream Cake
Boston cream cake is endlessly adaptable. Let’s explore some popular variations that can suit different tastes and dietary needs.

Gluten-Free Boston Cream Cake Recipe

Troubleshooting, Serving Ideas, and FAQs for Boston Cream Cake
Troubleshooting Boston Cream Cake Problems
Even the best bakers run into issues. Here are common problems you might encounter with Boston cream cake and how to fix them.
Why Did My Custard Filling Turn Out Runny?
Custard filling that’s too runny can be frustrating, but it’s a common problem with an easy fix.
- Causes:
- Insufficient cooking time. The custard needs to reach the right temperature for the cornstarch to thicken properly.
- Not enough cornstarch or egg yolks in the recipe.
- Solutions:
- Whisk the custard over medium heat until it thickens enough to coat the back of a spoon.
- If the custard has already cooled and is still runny, try reheating it gently and adding a slurry of cornstarch mixed with cold milk.
Pro Tip: “Always cool your custard with plastic wrap pressed directly on the surface to prevent condensation from watering it down.”

How to Avoid a Dense or Dry Cake Base
Dense or dry cakes are often the result of overmixing or overbaking.
- Causes:
- Overmixing the batter, which develops too much gluten.
- Overbaking, which dries out the cake.
- Solutions:
- Mix the batter just until the dry ingredients are incorporated.
- Set a timer and check for doneness 2–3 minutes before the recipe suggests.
Quick Tip: “For extra moisture, brush the cake layers with a light sugar syrup before adding the custard.”
Preventing Cracks in the Chocolate Glaze
Cracks in the glaze can detract from the cake’s appearance.
- Causes:
- The glaze was applied while too hot.
- The cake was too cold, causing the glaze to harden unevenly.
- Solutions:
- Let the glaze cool slightly before pouring it over the cake.
- Bring the cake to room temperature before adding the glaze for a smooth finish.
