Paper or silicone cupcake liners

How to Make Boston Cream Cupcakes: Step-by-Step

Step 1: Make the Cupcakes

Preheat your oven to 350°F (175°C) and line a cupcake pan with liners.

In a large bowl, whisk together the flour, sugar, baking soda, and baking powder.

Add the butter, egg whites, vanilla, sour cream, and milk. Use an electric mixer to beat until the batter is smooth and light—about 2–3 minutes.

Fill each cupcake liner about ⅔ full and bake for 18–20 minutes, or until a toothpick inserted in the center comes out clean. Let cool in the pan for 5 minutes, then transfer to a wire rack.

Step 2: Prepare the Pastry Cream

In a medium saucepan, heat the heavy cream over medium heat until it just begins to simmer—don’t boil.

In a separate bowl, whisk together the egg yolks, sugar, and cornstarch until smooth.

Gradually pour the hot cream into the yolk mixture, whisking constantly to temper the eggs.

Return the mixture to the saucepan and cook over medium heat, stirring constantly until thickened (about 2–4 minutes).

Remove from heat, stir in the vanilla extract, and transfer to a bowl. Cover with plastic wrap (pressing it directly onto the surface) and chill for at least 1 hour.

Step 3: Make the Chocolate Ganache

Heat the heavy cream in a small saucepan until it starts to simmer.

Place the chopped chocolate in a bowl and pour the hot cream over it. Let sit for 2 minutes, then stir gently until smooth and glossy.

Let the ganache cool slightly before using so it thickens just enough for dipping.

Step 4: Assemble the Cupcakes

Use a paring knife or cupcake corer to cut out a small well in the center of each cupcake.

Spoon about 1 teaspoon of ganache into the hole and freeze briefly (about 10 minutes) to set the layer.

Pipe or spoon chilled pastry cream over the ganache layer to fill the cupcake.

Dip the top of each cupcake into the remaining ganache. Allow to set at room temperature or chill for a firmer top.

Tips, Tricks, and Swaps

Make-Ahead: The pastry cream and ganache can be made up to 2 days in advance and stored in the refrigerator.
Flavor Boost: Add a teaspoon of espresso powder to the ganache for a mocha twist.
No sour cream? Substitute with full-fat Greek yogurt.
Dairy-Free Option: Use plant-based butter, dairy-free sour cream, and coconut cream for the ganache and filling.
Mini Version: Use a mini muffin pan for bite-sized versions—perfect for parties or dessert tables.

Storage and Leftovers

How to Store:

Store cupcakes in an airtight container in the refrigerator for up to 3 days. Because of the pastry cream, they must be kept cold.

Freezing:

You can freeze the unfilled cupcakes for up to 1 month. Thaw and fill as needed.

Reheating:

These are best served cold or at room temperature. Reheating is not recommended, as it may alter the texture of the cream and ganache.

Serving Suggestions

These cupcakes are elegant enough to be served as a dessert at dinner parties, weddings, or holiday gatherings.

Pair them with:

Espresso or cappuccino for a café-style treat
Champagne for a classy dessert course
Berry compote for a fruity contrast

Frequently Asked Questions (FAQ)

Can I use boxed cake mix?

You can, but the flavor and texture won’t be as rich or moist. If short on time, a good-quality vanilla cake mix works in a pinch.

How far in advance can I make these?

The components can be made 1–2 days in advance. Assemble the cupcakes the day you plan to serve them for the best texture.

What kind of chocolate should I use?

Semi-sweet chocolate is classic, but you can use bittersweet or milk chocolate based on your preference.

Can I make this as a full cake instead?

Absolutely! Use the same batter and filling, bake in two 8-inch pans, and layer with pastry cream and ganache like a traditional Boston Cream Pie.

How do I make them gluten-free?

Use a 1:1 gluten-free flour blend in the cupcake batter. The filling and ganache are naturally gluten-free.

Final Thoughts

Boston Cream Cupcakes take everything you love about the original pie and turn it into a delightful, portable dessert. With their rich vanilla center, tender cake base, and glossy chocolate cap, these cupcakes are guaranteed to impress.

Perfect for birthdays, holidays, or just because, this recipe will earn a spot in your go-to dessert rotation.
