• 2 mixing bowls (one large, one medium)
• Medium saucepan
• Whisk (trust me, you’ll be besties with it during the pastry cream part)
• Hand mixer or stand mixer
• Measuring cups & spoons
• Fine mesh strainer (optional, but great for extra smooth cream)

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

1. Start with the Silky Pastry Cream Filling

Because what are Boston cream cupcakes without their luscious, creamy heart?

Step 1: Pour 1 cup of milk and 1 cup of heavy cream into a medium pot. Add a pinch of salt and 3 tablespoons of sugar. Set the heat to medium and stir now and then. Watch for tiny bubbles to appear at the edges — that means it’s ready. Don’t let it boil. Once it’s gently heated, take the pot off the stove and let it rest.

Step 2: In a bowl, beat 5 egg yolks with the last ⅓ cup of sugar and 3 tablespoons of cornstarch. Keep whisking until the mixture turns a light yellow and has a smooth, creamy texture. It should be thick, but still easy to pour — like a rich custard starter.

Step 3: Temper the eggs (fancy word, easy task) Slowly drizzle about ½ cup of the hot milk mixture into the egg yolks while whisking constantly. This step gently warms up the eggs so they don’t scramble. Once combined, pour the egg mixture back into the saucepan with the rest of the milk mix.

Step 4: Cook to pudding perfection Put the saucepan back on medium heat. Keep stirring steadily until the mixture thickens into a smooth, creamy texture — this usually takes around 2 to 3 minutes. You’ll know it’s ready when it coats the back of a spoon and leaves a trail when you run your finger through it.

Step 5: Add flavor & cool down Remove from heat and stir in 1 teaspoon vanilla extract and 4 tablespoons butter, one piece at a time. When the mixture is fully melted and silky, transfer it to a bowl. Place a layer of plastic wrap directly against the mixture to stop a crust from developing on top. Chill it in the fridge for at least 2 hours (or up to 3 days!).

Tip: If you’re fancy or patient, you can strain it through a mesh sieve for the smoothest pastry cream ever.

2. Let’s Bake Those Boston Cream Cupcakes

Time for the cakey part of our Boston cream cupcakes. These are buttery, fluffy, and built to cradle that pastry cream like a pro.

Step 1: Preheat & prep Set your oven to 350°F (175°C) and line a standard muffin tin with cupcake liners. You’ll get around 12 to 14 cupcakes from this batter, give or take, depending on how much you fill each cup.

Step 2: Cream butter, oil & sugar In a large bowl, use a mixer to blend ½ cup softened butter, ½ cup avocado oil, and 1¾ cups sugar until light and fluffy—about 2–3 minutes. That air is your secret to soft cupcakes.

Step 3: Add eggs & vanilla Mix in 4 large eggs, one at a time. Scrape the bowl after each addition to make sure everything gets cozy. Stir in 2 teaspoons vanilla extract.

Step 4: In a separate bowl, blend 3 cups of flour with 1 tablespoon of baking powder and ¾ teaspoon of salt. Stir well until all the ingredients are mixed together smoothly and evenly.

Step 5: Gradually add the flour mix to the wet ingredients, doing it in three parts. Between each addition, pour in a bit of the 1¼ cups of buttermilk, mixing as you go. Start and end with dry ingredients. Mix until just combined—don’t overbeat unless you want tough cupcakes (nobody does).

Step 6: Bake! Fill each cupcake liner about ¾ full. Bake for 18–20 minutes, or until a toothpick poked in the center comes out clean. Let the cakes rest in the pan for about 5 minutes, then carefully move them to a cooling rack to finish cooling down completely.

3. Fill ‘Em Up with Creamy Goodness

Once your Boston Cream Cupcakes are cool and your pastry cream is chilled, it’s time for the best part.

Step 1: Core the cupcakes Use a small knife or piping tip to cut a little cone out of the center of each cupcake. Don’t go too deep—just enough to tuck in some of that golden goodness.

Step 2: Fill with pastry cream Spoon or pipe in the pastry cream until each cupcake is full (a little dome is totally okay—it’s a sign of abundance!). Pop the cupcake tops back on if you want or leave them open for the ganache to seal the deal.

4. Ganache Time

That glossy chocolate topping is what gives Boston cream cupcakes their drama.

Step 1: Melt the magic In a microwave-safe bowl, combine 1 cup semisweet chocolate chips, ½ cup heavy cream, and 2 tablespoons light corn syrup. Heat in the microwave for 30 seconds at a time, giving it a good stir after each round, until it’s fully melted and silky.

Step 2: Add sweetness Whisk in ⅓ cup powdered sugar until smooth and pourable. Let it cool slightly so it thickens just enough to cling.

Step 3: Top it off Spoon ganache over each filled cupcake, letting it drip down the sides like a little chocolate waterfall. You can use the back of a spoon to swirl it around or leave it artfully messy. Either way, they’ll look bakery-worthy.

Cooking Tips for Sweet Success

• Don’t overfill the Boston Cream Cupcakes or the cream will rebel and burst out like a volcano.
• If your ganache is too runny, let it cool a few more minutes—it thickens fast.
• Want to make these ahead? Bake the cupcakes and store them unfilled for 2 days. Fill and frost just before serving for peak deliciousness.
• Cupcake liners peeling away? That’s usually from too much moisture. Let them cool fully before storing.

Bonus: If you accidentally eat three cupcakes while “taste-testing,” it’s totally valid research.

From My Kitchen to Yours

The first time I made these, it was a rainy Sunday, and my kids were bouncing off the walls. I needed a project to keep them occupied—and myself sane. We baked, filled, and frosted these Boston Cream Cupcakes together, and by the end, the kitchen looked like a chocolate tornado hit it… but they were grinning ear to ear.

Since then, these Boston cream cupcakes have become a family tradition. They’re my go-to for birthdays, school treats, or just because the day needs a little sugar. And honestly? That moment when you bite in and hit the cool pastry cream? Pure joy.

Storage Tips: Keeping Your Boston Cream Cupcakes Fresh and Fabulous

Let’s be honest—leftovers of these cupcakes are rare. But just in case your self-control wins out or you bake a big batch (go you!), here’s how to keep your Boston cream cupcakes tasting bakery-fresh:

• Refrigeration is your BFF. Because of that dreamy pastry cream, these cupcakes need to be stored in the fridge. Store them in a sealed container, and they should stay fresh for about four days. I recommend letting them sit at room temp for 15–20 minutes before serving so the ganache softens and flavors shine.
• Freezing? Yes, with a twist. Freeze unfilled cupcakes and unmade ganache for up to 2 months. Wrap each cupcake individually in plastic wrap, then store in a freezer bag. When you’re ready, thaw at room temp, fill with fresh pastry cream, and top with ganache. Trust me, they’ll taste like you made them that day.
• Avoid soggy bottoms. Humidity in the fridge can cause your cupcake liners to go a bit wonky. To prevent soggy cupcake bottoms, store them in a single layer—not stacked—and add a paper towel beneath them to soak up excess moisture, For More Storage Tips Go to the best tips to help you.

Frequently Asked Questions

Can I substitute the buttermilk in this Boston Cream Cupcakes recipe?

Yes! If you don’t have buttermilk on hand, you can mix 1 tablespoon of lemon juice or white vinegar with 1¼ cups of milk. Let it sit for 5–10 minutes before using. It won’t taste exactly the same, but your Boston cream cupcakes will still be tender and delicious.

Do I really need to chill the pastry cream?

Definitely. Chilling allows it to thicken and set properly, which keeps it from oozing out when you fill your Boston Cream Cupcakes. It’s the key to those picture-perfect boston cream cupcakes.

How should I store leftover Boston Cream Cupcakes?

Since they’re filled with cream, store any leftover boston cream cupcakes in an airtight container in the fridge for up to 4 days. Let them sit out a bit before serving for best flavor and texture.

Is it okay to prepare Boston Cream Cupcakes in advance?

Definitely! You can easily make the cupcakes and the cream filling one or two days before you need them. For the best flavor and appearance, put everything together and add the topping on the day you plan to serve them.

What’s the best way to fill the Boston Cream Cupcakes?

Use a piping bag fitted with a round tip, or a zip-top bag with the corner snipped off. You can also spoon it in—just be sure to cut a well in the center first. Either way, your Boston cream cupcakes will be beautifully filled.
