I first made this recipe on a chilly afternoon with my kids. We had leftover cake mix in the pantry and a craving for something sweet, so we got creative.

Why You’ll Love This Recipe

These Boston Cream Pie Cupcakes aren’t just beautiful—they’re little bundles of joy in cupcake form. Here’s why you’ll fall head over heels for them (just like I did the first time I made a batch).

Rich, Moist Vanilla Cake

The foundation of these cupcakes is a soft, golden vanilla cake that’s light, fluffy, and just the right amount of sweet. The texture is airy enough to melt in your mouth, yet sturdy enough to hold a generous spoonful of custard in the center without falling apart.

And the best part? You can use a simple box mix for a quick version or make the cake batter from scratch if you’re in the mood for some extra baking therapy. Either way, you’ll get that warm, buttery vanilla flavor that sets the perfect stage for all the deliciousness layered on top.

Creamy Pastry Cream Filling

Nestled inside each cupcake is a surprise: a silky-smooth pastry cream that adds richness without overwhelming sweetness. It’s made from scratch (but don’t worry, it’s easier than it sounds!) and has the velvety texture of a bakery-quality custard.

This creamy center adds an elegant contrast to the fluffy cake. It’s the kind of detail that makes your guests say, “Wow, you really made these?” And if you’ve never made pastry cream before, this recipe is a great place to start—it’s forgiving, foolproof, and so worth it.

Foolproof Chocolate Ganache

Ah, the ganache—the final touch that ties everything together. This glossy, decadent chocolate topping is made with just two ingredients: heavy cream and chocolate chips. That’s it!

It melts together into a rich, silky glaze that spreads like a dream and sets up into a soft, fudgy layer. Not only does it add that iconic “Boston cream pie” look, but it also brings the flavor home with a chocolatey finish that balances the vanilla and custard beautifully.

Beginner-Friendly & Customizable

One of the best things about this recipe? It’s super approachable. You don’t need to be a pastry chef to pull off these show-stopping cupcakes. With a few pantry staples and a bit of patience, anyone can make them—yes, even if your last attempt at baking involved a burnt cookie sheet.

Here’s why it’s great for all levels:

Use boxed cake mix for ease, or go scratch-made for extra flair.
Pastry cream can be swapped with vanilla pudding in a pinch.
Don’t have a cupcake corer? A small knife or piping tip works just fine.

Whether you’re baking for a birthday party, holiday dessert table, or just because, these cupcakes fit right in. And once you’ve mastered the basic version, you can play with flavors—think mocha ganache, almond custard, or even a berry twist. It’s a canvas for creativity, and one that always ends in something delicious.

How to Make Boston Cream Pie Cupcakes

This recipe might look bakery-fancy, but trust me—it’s totally doable at home, even if you’re short on time or experience. Each step is straightforward and builds on the last, resulting in a cupcake that looks impressive and tastes like pure joy.

Step-by-Step Instructions

1. Preheat the oven and prep your tin.
Preheat your oven to 350°F (175°C). Line a 12-cup muffin tin with cupcake liners. This ensures easy cleanup and keeps your cupcakes looking neat.

2. Prepare and bake the cupcakes.
Follow the instructions on the yellow cake mix box to prepare your batter. Fill each cupcake liner about two-thirds full.
Bake according to the package timing (usually 18–22 minutes), until a toothpick comes out clean.
Let the cupcakes cool completely before moving on—this is key for easy filling.

3. Make the pastry cream.
In a small saucepan, whisk together milk, sugar, and cornstarch over medium heat until smooth.
Slowly whisk in egg yolks, and continue stirring constantly until the mixture thickens—this should take about 5 minutes.
Remove from heat and stir in butter and vanilla extract until fully incorporated.
Transfer the custard to a bowl, press plastic wrap against the surface to prevent a skin, and chill in the fridge until cold.

4. Make the chocolate ganache.
Heat heavy cream in a small saucepan until it just begins to simmer—don’t let it boil!
Pour the hot cream over the chocolate chips in a heatproof bowl. Let sit for 2 minutes, then stir gently until smooth and glossy.
Add vanilla extract, and stir to combine. Set aside to cool slightly.

5. Assemble the cupcakes.
Once the cupcakes are cool, use a paring knife or cupcake corer to remove a small section from the center of each.
Fill the cavity with chilled pastry cream using a piping bag or small spoon.
Spoon or drizzle ganache over the top of each cupcake, letting it gently cascade over the edges.
Refrigerate for at least 30 minutes to let everything set beautifully.

Variations and Substitutions

One of the best things about Boston Cream Pie Cupcakes is how flexible the recipe can be. Whether you're working with dietary restrictions or just feeling adventurous, there are lots of ways to make these cupcakes your own. Here are a few tried-and-true variations that keep the charm of the original while giving it a fun twist.

Gluten-Free Option

Simply swap the standard yellow cake mix for a gluten-free version (many grocery stores now carry great options!).
Double-check that all other ingredients—especially vanilla extract and chocolate chips—are certified gluten-free to avoid cross-contamination.

Extra Chocolate Version

Add a small spoonful of fudge sauce or melted chocolate to the cupcake center before the pastry cream for a double-chocolate surprise.
Use dark chocolate chips in the ganache for a deeper, more intense chocolate flavor.

Dairy-Free Option

Replace the milk in the custard with unsweetened almond milk, oat milk, or coconut milk.
Use vegan butter and dairy-free chocolate chips for the filling and topping.
The result? Still rich and indulgent—just friendly for non-dairy eaters!

You’ve baked, filled, and topped your beautiful cupcakes—now how do you keep them fresh? Here’s how to store them properly for maximum flavor and texture.

Room Temperature

If unfilled, cupcakes can be kept at room temperature for up to 12 hours.

Refrigeration Tips

Store assembled cupcakes in an airtight container in the fridge.
They’ll stay fresh for about 3 days, though they’re best within the first 24–48 hours.

Freezing Instructions

Freeze the unfilled cupcakes and ganache separately for up to a month.
Thaw cupcakes overnight in the fridge and assemble the day you plan to serve for best results.

Recipe Tips and Tricks

Want bakery-worthy results every time? Here are a few simple but powerful tips to make your cupcakes shine:
