Ingredients You’ll Need

These Boston Cream Cupcakes come together with simple, pantry-friendly ingredients that each play a key role in crafting a dessert you’re going to love. From the soft crumb of the cupcakes to the smooth custard and decadent chocolate glaze, every component adds its own magic to the final result.

• All-purpose flour: The backbone of our cupcakes, providing structure and a tender crumb.
• Baking powder: Helps the cupcakes rise beautifully and stay light.
• Salt: Enhances all the flavors and balances sweetness perfectly.
• Unsalted butter: Adds richness and moisture to the cake and filling.
• Granulated sugar: Sweetens both the cupcakes and the pastry cream for a balanced taste.
• Large eggs: Provide structure and help bind everything together smoothly.
• Pure vanilla extract: Infuses the cupcakes and filling with warm, inviting aroma.
• Whole milk: Adds moisture and richness to the cake batter and custard.
• Cornstarch: Thickens the pastry cream to that perfect velvety consistency.
• Heavy cream: Essential for making the chocolate ganache glossy and smooth.
• Semisweet or dark chocolate: Gives the ganache its rich, luscious chocolate flavor.

How to Make Boston Cream Cupcakes

Step 1: Make the Pastry Cream Filling

The pastry cream is the heart of these Boston Cream Cupcakes, so it’s important to get it just right. Start by heating milk until it’s steaming but not boiling to prevent curdling. Whisk together egg yolks, sugar, and cornstarch until pale and silky, then gradually blend in the hot milk. Cooking this mixture gently while stirring constantly makes sure it thickens smoothly without lumps. Finishing with butter and vanilla adds a glossy, rich touch. Once chilled, this creamy custard will be ready for filling the cupcakes.

Step 2: Bake the Vanilla Cupcakes

Next up, the vanilla cupcakes, which provide a tender yet sturdy base for all that luscious filling and ganache. Combine the dry ingredients separately to evenly distribute the leavening, then cream butter and sugar until fluffy — this step is crucial for lightness. Add the eggs one at a time for consistent texture, then alternate folding in flour and milk for a perfectly smooth batter. Fill your cupcake liners about two-thirds full so they rise beautifully without spilling over. After baking for 18 to 20 minutes, cool them completely before moving to the filling step.

Step 3: Fill the Cupcakes with Pastry Cream

Once your cupcakes are cool, it’s time for the exciting transformation. Using a knife or a cupcake corer, gently hollow out the center of each cupcake, careful not to puncture the bottom. Fill each cavity generously with the chilled pastry cream—this custard is what makes these cupcakes truly shine. Replace the tops you cut out for a seamless look and a delightful surprise inside every bite.

Step 4: Prepare and Add the Chocolate Ganache

The final flourish is the luxurious chocolate ganache topping. Heat the heavy cream until it simmers, then pour it over finely chopped chocolate and let sit briefly—this melting and resting step ensures smooth amalgamation. Stir until shiny and silky, then whisk in a bit of butter to give your ganache that irresistible gloss. Let it cool slightly so it’s thick enough to coat the cupcakes elegantly without dripping messily. Dip each filled cupcake or spoon the ganache over the tops, then allow it to set before serving.

How to Serve Boston Cream Cupcakes

Garnishes

While these Boston Cream Cupcakes look stunning as is, you can elevate their presentation and flavor with a few garnishes. A dusting of powdered sugar around the edges adds a classic touch. Fresh berries, especially raspberries or strawberries, provide a pop of color and a refreshing contrast to the creamy sweetness. For an indulgent touch, a few chocolate shavings or a sprinkle of toasted nuts also work beautifully.

Side Dishes

Pair these cupcakes with a cup of rich coffee or black tea to balance the richness of the pastry cream and ganache. For a brunch or dessert buffet, fresh fruit salad or a simple green salad with a light vinaigrette adds a nice bright counterpoint to the cupcakes’ decadence. A scoop of vanilla or coffee ice cream can turn this treat into an over-the-top celebration.

Creative Ways to Present

If you want to wow guests, serve the Boston Cream Cupcakes on a tiered cake stand for a charming display. Individual glass cloches or small dessert bowls make elegant single servings. You could even place each cupcake next to a small jar of extra pastry cream or ganache for those who want seconds or like to add their own swirl of flavor.

Make Ahead and Storage

Storing Leftovers

Boston Cream Cupcakes are best enjoyed fresh, but if you have leftovers, store them in an airtight container in the refrigerator. The pastry cream needs the chill to stay safe and fresh, and chilling helps the ganache keep its perfect texture. They’ll stay delicious for up to 3 days.

Freezing

You can freeze Boston Cream Cupcakes, but keep in mind that the texture of the pastry cream might change slightly upon thawing. Wrap each cupcake tightly in plastic wrap and place them in a freezer-safe container. They’ll keep well for up to one month. Thaw them overnight in the fridge before serving for best results.

Reheating

Since these cupcakes contain pastry cream, reheating is not recommended as it could affect texture and food safety. Instead, serve them chilled or at room temperature to fully enjoy their creamy filling and silky ganache topping.

FAQs

Can I use whipped cream instead of pastry cream in Boston Cream Cupcakes?

Whipped cream will give a lighter filling but won’t provide the same rich custard texture and flavor that make Boston Cream Cupcakes special. For the authentic experience, the pastry cream is key.

How can I make sure my pastry cream doesn’t curdle?

Temper the eggs by gradually adding the hot milk while whisking constantly. Also, cook the mixture gently over medium heat and keep stirring to prevent the eggs from scrambling.

Can I make Boston Cream Cupcakes gluten-free?

Yes! Substitute the all-purpose flour with a gluten-free flour blend suitable for baking. Just make sure it contains xanthan gum or a similar binder to maintain the cupcake’s structure.

Is it okay to use milk chocolate instead of dark or semisweet for the ganache?

You can, but milk chocolate will make the ganache sweeter and lighter in flavor. Semisweet or dark chocolate provides a richer balance that complements the custard and vanilla cupcake beautifully.

How far in advance can I assemble the cupcakes?

It’s best to assemble them the day you plan to serve to keep everything fresh, but you can make the cupcakes and pastry cream up to two days ahead and keep them refrigerated. Assemble and add ganache on serving day for the best texture and flavor.
