- 1 2/3 cups all-purpose flour: The base that gives structure and softness to the cupcakes.
- 1 cup granulated sugar: Adds sweetness and helps achieve a tender crumb.
- 1/4 tsp baking soda: Assists in leavening for a light, airy texture.

- 2 tsp pure vanilla extract: Infuses the batter with warm, comforting flavor.
- 1/2 cup sour cream: Adds a subtle tang and makes the cupcakes extra tender.
- 1/2 cup whole milk: Balances moisture and creates a smooth batter.
- 1 cup heavy cream: Essential for creating the luscious pastry cream filling.
- 2 large egg yolks: Provide richness and help thicken the pastry cream.
- 3 tbsp granulated sugar: Sweetens the pastry cream without overpowering it.

- 1 tsp pure vanilla extract: Adds extra aromatic depth to the filling.

How to Make Boston Cream Cupcakes Recipe
Step 1: Prepare the Cupcakes
Start by preheating your oven and readying a cupcake pan with liners because you are about to create a batter that’s a perfect harmony of dry and wet ingredients. Mix the flour, sugar, baking soda, and baking powder in one bowl. In a separate bowl, beat the room temperature butter until creamy, then add the egg whites one at a time, blending in the vanilla extract, sour cream, and milk. Slowly incorporate the dry ingredients to the wet, stirring just until combined. Divide the batter evenly into the cupcake liners and bake until golden and springy to the touch. You’ll know they’re done when a toothpick comes out clean and the enticing aroma fills your kitchen.
Step 2: Make the Pastry Cream Filling
The magic filling is where this Boston Cream Cupcakes Recipe truly shines. In a saucepan, gently heat 1 cup of heavy cream just until it starts to simmer. Meanwhile, whisk the egg yolks, sugar, cornstarch, and vanilla in a separate bowl until smooth and pale. Slowly pour the hot cream into the egg mixture while whisking constantly to temper the eggs. Return the mixture to the saucepan and cook over medium heat, stirring continuously until thickened to creamy custard perfection. Avoid rushing this step, as it ensures a silky texture without scrambling the eggs. Once thick, transfer the pastry cream to a bowl, cover with plastic wrap directly on the surface to prevent a skin from forming, and chill until firm.
Step 3: Prepare the Chocolate Ganache
While the pastry cream chills, let’s make the decadent ganache. Warm 1/2 cup of heavy cream in a small saucepan or microwave just until it’s hot but not boiling, then pour it over your chopped semi-sweet chocolate. Let it sit for a minute, then stir gently until you have a smooth, glossy mixture that practically begs to be dipped into. This ganache will coat the cupcakes and make them look simply stunning.
Step 4: Assemble the Cupcakes
Here’s where the fun really begins. After the cupcakes have cooled, use a small knife or cupcake corer to remove a small cylinder of cake from the center of each cupcake. Fill each hollow with a spoonful of the silky pastry cream, then dip each cupcake top into the chocolate ganache, allowing the excess to drip down the sides for that signature glossy finish. Let them set slightly so the ganache firms up, and you’ve got yourself an irresistible treat that’s ready to impress.
How to Serve Boston Cream Cupcakes Recipe
Garnishes
To elevate your Boston Cream Cupcakes Recipe presentation, consider adding a delicate dusting of powdered sugar for a touch of elegance or a few fresh berries for a burst of color and tartness. A small mint leaf on top adds a lovely contrast visually and a fresh aroma that everyone will appreciate.
Side Dishes
These cupcakes are rich and indulgent on their own, but pairing them with a light, refreshing cup of tea or coffee balances the flavors beautifully. A fresh fruit salad or simple whipped cream on the side also complements the creamy, chocolatey goodness without overpowering it.
Creative Ways to Present
If you want to impress guests, serve these cupcakes in decorative cupcake wrappers or atop pretty dessert plates with a drizzle of extra ganache or caramel sauce. For a party, arrange them on a tiered cupcake stand to highlight their beauty and make it easy for everyone to grab a bite of this classic favorite reinvented.
Make Ahead and Storage
Storing Leftovers
Once assembled, store your Boston Cream Cupcakes Recipe in an airtight container in the refrigerator. This helps keep the pastry cream fresh and the ganache glossy. They will stay delicious for up to 3 days, making it perfect if you want to prepare them in advance for a celebration.
Freezing
Freezing assembled cupcakes is not recommended as the pastry cream tends to separate and change texture upon thawing. However, you can freeze the cupcakes before filling and ganaching. Wrap them tightly in plastic wrap and foil, then freeze for up to 1 month. When ready, thaw completely, then fill and top as directed.
Reheating
Because of the delicate filling, reheating is best avoided for this Boston Cream Cupcakes Recipe. Serve them chilled or at room temperature to enjoy the perfect texture and flavor every time.
FAQs
Can I use whole eggs instead of separating them?
While whole eggs can be used in some cupcake recipes, this Boston Cream Cupcakes Recipe relies on the separation for lightness and structure. Egg whites keep the cupcakes fluffy without adding heaviness, while yolks enrich the pastry cream filling.
How do I know when the pastry cream is thick enough?
The pastry cream should be thick enough to coat the back of a spoon without running off too quickly. When you stir it, the mixture will look glossy and hold its shape near the spoon’s surface.
Can I make the pastry cream in advance?
Absolutely! Making the pastry cream a day ahead allows it to fully chill and develop flavor. Just keep it covered tightly with plastic wrap on the surface to prevent a skin from forming.
What type of chocolate is best for the ganache?
Semi-sweet chocolate is ideal for balancing the sweetness of the pastry cream and cupcake. You can experiment with bittersweet or milk chocolate depending on your taste preference.
Are there any tips for achieving a smooth ganache?
Yes, make sure the cream is hot but not boiling, and pour it over chopped chocolate to let it melt gently. Stir slowly and gently to combine without introducing air bubbles for that glossy smooth finish.
Final Thoughts
There’s something incredibly special about this Boston Cream Cupcakes Recipe that feels both nostalgic and wonderfully fresh. From the tender cupcakes to the creamy filling and the shiny chocolate topping, every element works beautifully together to create a dessert that’s sure to become one of your favorites. I encourage you to give this recipe a try and watch your friends and family delight in every bite. Happy baking!

Ingredients
Cupcakes
- 1 2/3 cups all-purpose flour
- 1 cup granulated sugar
- 1/4 tsp baking soda
- 1 tsp baking powder
- 3/4 cup unsalted butter, at room temperature
- 3 large egg whites
- 2 tsp pure vanilla extract
- 1/2 cup sour cream
- 1/2 cup whole milk
Pastry Cream Filling
- 1 cup heavy cream
- 2 large egg yolks
- 3 tbsp granulated sugar
- 1 tbsp cornstarch
- 1 tsp pure vanilla extract
- 1/2 cup heavy cream (for whipping)
Chocolate Ganache
- 6 oz semi-sweet chocolate, chopped
- 1/2 cup heavy cream (to melt chocolate)
Instructions
- Prepare the cupcakes: Preheat your oven and line a cupcake tin with liners. In a mixing bowl, whisk together the all-purpose flour, granulated sugar, baking soda, and baking powder. In a separate bowl, beat the butter until creamy, then gradually add egg whites and vanilla extract. Alternate adding the dry ingredients with sour cream and whole milk until fully combined. Divide the batter evenly into cupcake liners and bake for about 20 minutes or until golden brown and a toothpick inserted comes out clean. Let cool completely.
- Make the pastry cream filling: In a saucepan, heat 1 cup of heavy cream until it just begins to simmer. In a separate bowl, whisk together egg yolks, granulated sugar, and cornstarch until smooth. Slowly pour the hot cream into the egg mixture while whisking constantly to temper the eggs. Return the mixture to the saucepan and cook over medium heat, whisking continuously until thickened to a custard-like consistency. Remove from heat, stir in vanilla extract, and transfer the pastry cream to a bowl. Cover with plastic wrap directly on the surface to prevent a skin from forming and refrigerate until chilled. Before assembling, whip the remaining 1/2 cup heavy cream until stiff peaks form and fold into the chilled pastry cream to lighten it.
- Prepare the chocolate ganache: Place the chopped semi-sweet chocolate in a heatproof bowl. Heat the 1/2 cup heavy cream until hot but not boiling, then pour it over the chocolate. Let sit for 2 minutes, then stir gently until smooth and glossy. Allow to cool slightly to thicken, but still pourable.
- Assemble the cupcakes: Once cupcakes are cooled, use a small knife or cupcake corer to hollow out the center of each cupcake. Fill each cavity with a spoonful of the pastry cream. Replace the tops if desired or leave open. Dip the top of each cupcake into the chocolate ganache or spoon the ganache over the top to cover completely. Place the cupcakes in the refrigerator for the ganache to set slightly before serving.
Notes
- Ensure cupcakes are fully cooled before filling to prevent the pastry cream from melting.
- The pastry cream can be made a day ahead to save time.
- Use good-quality semi-sweet chocolate for a balanced flavor.
- For best results, chill assembled cupcakes for at least 30 minutes before serving.
- If you prefer, the cupcakes can be topped with chocolate glaze using a spoon instead of dipping.
