Preparing Boston Cream Pie Cupcakes
Making Boston Cream Pie Cupcakes is an enjoyable venture that combines the rich flavors of vanilla and chocolate into delightful little treats. Here’s a step-by-step guide to help you whip up these delicious cupcakes with ease.
Preheat and prepare your baking pan
Start off by preheating your oven to 350°F (176°C). This is essential because a properly heated oven ensures even baking. While the oven warms up, grab a cupcake pan and line it with gorgeous cupcake liners. Not only do these add a pop of color, but they also make it easy to pop the cupcakes out when they’re done baking.
Make the vanilla cupcake batter
In a large mixing bowl, cream together 6 tablespoons of room-temperature unsalted butter and ¾ cup of sugar until the mixture turns light and fluffy. This should take about 3-4 minutes, so don’t rush this critical step! Next, mix in 6 tablespoons of sour cream and 2 teaspoons of vanilla extract until everything is well combined.
Now comes the fun part—adding in your eggs! Incorporate 3 large egg whites in two batches, mixing well after each addition. Don’t forget to scrape down the sides of the bowl to ensure all ingredients blend beautifully. Combine your 1 ¼ cups of flour, 2 teaspoons of baking powder, and ¼ teaspoon of salt in a separate bowl. Alternately add the dry ingredients and a mixture of 6 tablespoons of milk and 2 tablespoons of water into the batter until everything is smoothly incorporated.
Bake the cupcakes
Fill your cupcake liners about halfway full with the batter—this should yield about 12 cupcakes. Bake them in your preheated oven for 15-17 minutes. You’ll know they’re ready when a toothpick inserted into the center comes out with a few crumbs. Once baked, let them cool in the pan for a few minutes before transferring to a wire rack.
Whip up the pastry cream filling
While the cupcakes chill, it’s time for the star of the show: the pastry cream. In a medium bowl, gently beat together 2 egg yolks. In a saucepan, combine 6 tablespoons of sugar, 1 ½ tablespoons of cornstarch, and 1 cup plus 2 tablespoons of milk, mixing until smooth. Cook this mixture over medium-high heat, stirring continuously until it thickens and bubbles. This process is crucial to get that creamy consistency.
Create the chocolate ganache
For that luscious chocolate layer, combine 12 ounces of semi-sweet chocolate chips and 2 tablespoons of light corn syrup in a large bowl. Meanwhile, bring ¾ cup plus 2 tablespoons of heavy whipping cream to a boil, then pour it over the chocolate mixture and let it sit for 3-5 minutes. Whisk until smooth and glossy before placing it in the fridge to cool for 1-2 hours.
Fill and decorate the cupcakes
Once your cupcakes and pastry cream have cooled, it’s time to assemble your Boston Cream Pie Cupcakes. Use a cupcake corer or a knife to remove the centers of the cupcakes, creating pockets for your creamy filling. Divide the luscious pastry cream among the cupcakes generously.
Now, for the finishing touch, drizzle or pipe your chocolate ganache over the filled cupcakes. You can create beautiful swirls and designs using a piping bag; I recommend using an Ateco tip 844 or a Wilton 2D/1M.
After all that hard work, refrigerate your cupcakes until you’re ready to impress friends or family—though they might disappear quickly! Enjoy your homemade Boston Cream Pie Cupcakes fresh and indulging; they’re best eaten within 3-4 days. Happy baking!

Baking notes for Boston Cream Pie Cupcakes
Tips for perfecting the cupcakes
To make your Boston Cream Pie cupcakes truly shine, consider these handy tips:
- Use room temperature ingredients: Ensuring your butter, eggs, sour cream, and milk are at room temperature helps achieve a smoother batter.
- Don’t skip the creaming step: Creaming the butter and sugar adequately (3-4 minutes) incorporates air, resulting in a light texture.
- Keep an eye on baking time: Begin checking your cupcakes at the 15-minute mark. Overbaking can lead to dryness.
Common mistakes to avoid
Steer clear of these common pitfalls:
- Overmixing the batter: This can lead to dense cupcakes. Mix just until ingredients are combined.
- Skipping the cooling period: Allowing your cupcakes and pastry cream to cool properly enhances flavors and textures.
- Filling liners too full: Aim for halfway; otherwise, you may end up with cupcakes that spill over.
