Ingredients You’ll Need

Just gather a few kitchen basics. Here’s what each component does:

• Butter (for richness and tenderness): Softened, so it creams beautifully with sugar.
• Sugar (for sweetness and structure): Rounds out the flavors and gives the cupcakes the perfect crumb.
• Vanilla (for warmth and depth): Enhances both the cake and pastry cream; real extract works best.
• Eggs (for binding and lightness): Crucial for that moist, fluffy texture.
• Flour (for structure): All-purpose gives the best, soft result.
• Baking Powder (for lift): Helps the cupcakes rise tall and proud.
• Salt (for balance): Just a touch enlivens all the flavors.
• Buttermilk (for moisture and subtle tang): Keeps the crumb super tender.
• Egg Yolks (for the custard filling): The yolks make the pastry cream lusciously rich.
• Milk (for the custard base): Whole milk adds creaminess; low-fat will work in a pinch.
• Cornstarch (for thickening the filling): Ensures your pastry cream is perfectly thick and spoonable.
• Semi-Sweet Baking Chocolate (for the ganache): Go for quality chocolate—this is what gives the topping its signature shine and flavor.
• Heavy Cream (to melt the chocolate for ganache): This creates that dreamy, pourable consistency.

Tip: You can use prepared pudding instead of homemade pastry cream if you’re extra short on time!

Variations

These cupcakes are a dream for mix-ins and swaps:

• Flavor Twist: Add orange or almond extract to the cake or ganache.
• Different Filling: Use prepared vanilla or chocolate pudding if you’re in a true time crunch.
• No Ganache?: Melt chocolate chips with a splash of cream—a microwave shortcut!
• Gluten-Free: Use your favorite 1:1 gluten-free flour blend for a celiac-friendly version.
• Mini Version: Make tiny cupcakes for a party tray—just keep an eye on the bake time!

How to Make Boston Cream Pie Cupcakes

Step 1: Bake the Cupcakes

Cream the softened butter with sugar until it’s light and fluffy, then beat in the vanilla and eggs one by one, making sure each is fully incorporated. In another bowl, whisk the flour, baking powder, and salt. Alternate adding the flour mixture and buttermilk to your wet ingredients—starting and ending with flour—to keep everything smooth and lump-free. Line muffin pans and fill each cup about 3/4 full. Bake until golden and a toothpick comes out clean (18–25 minutes). Let them cool completely.

Step 2: Make the Vanilla Pastry Cream

In a bowl, whisk the egg yolks well, then gently blend in the milk. In a saucepan over medium-low heat, combine sugar, cornstarch, and salt. Slowly add the milk–egg mixture to the pan, stirring constantly. Keep stirring as the mixture thickens and just begins to boil—patience pays off here! Once thick, remove from heat, stir in vanilla, and set the pot in ice water to cool quickly. Lay plastic wrap directly on the cream to prevent a skin, and chill until needed.

Step 3: Prepare the Ganache

Chop the chocolate finely and place in a bowl. Heat the heavy cream in a saucepan until steaming but not boiling, then pour over the chocolate. Let it sit for a minute, then whisk until smooth and glossy. Let it cool until it’s thick enough to stick to the cupcakes but still pourable.

Step 4: Assemble

Transfer the chilled pastry cream to a piping bag with a filling tip. Carefully fill the center of each cooled cupcake. Dip the tops into the thickened ganache, letting the excess drip off, and set aside to let the chocolate set (30–60 minutes).

Pro Tips for Making the Recipe

• Don’t Rush the Custard: Keep the heat on medium-low and stir constantly—this keeps the pastry cream silky (no lumps!).
• Ganache Timing Is Everything: Let the ganache cool before dipping, or it’ll run off instead of coating beautifully.
• Room-Temperature Ingredients: The butter, eggs, and buttermilk blend best when not ice-cold.
• Fill Right Before Serving: Freshly filled cupcakes taste best; keep the parts separate if you’re prepping in advance.

How to Serve

Boston Cream Pie Cupcakes shine at any gathering! Arrange them on a pretty platter at room temperature for the softest cake and creamiest filling. Pair with coffee or a cold glass of milk—pure comfort. For special occasions, top with a curl of chocolate or a sprinkle of gold dust for extra flair.

Make Ahead and Storage

Storing Leftovers

Place the cupcakes in an airtight container and refrigerate. They’ll stay fresh for up to 2–3 days. Bring to room temperature for the best texture before serving.

Freezing

Unfilled, unfrosted cupcakes freeze beautifully—just wrap tightly. Thaw overnight in the refrigerator, then fill and ganache as desired.

Reheating

No need to reheat, but if you must, let them come to room temperature rather than actually warming them up, to keep the custard intact.

FAQs

How do I fill the cupcakes without making a mess?
The easiest way is with a piping bag fitted with a filling tip. Gently insert the tip into the center and squeeze until you see the cupcake swell slightly. No piping bag? Carefully cut out a small cone from the top, fill, and replace the lid!

Can I substitute the homemade custard with box pudding?
Absolutely! Prepare vanilla pudding according to the box and cool it completely before filling the cupcakes. The homemade version does taste richer, but pudding makes these a true weeknight treat.

My ganache is too runny. What should I do?
Just wait. Ganache thickens as it cools. If it’s still thin after cooling, whisk in a little more chopped chocolate.

Do these need to be refrigerated?
Yes! Because of the pastry cream (or pudding) filling, store the cupcakes in the refrigerator if not serving within two hours.
