How to Make Boston Cream Pie Cupcakes

Ingredients

• 6 tbsp (84g) unsalted butter, room temperature (I use Challenge Butter)
• 3/4 cups (155g) sugar
• 6 tbsp (86g) sour cream, room temperature
• 2 tsp (10ml) vanilla extract
• 3 large egg whites, room temperature
• 1 1/4 cups (163g) all-purpose flour
• 2 tsp (8g) baking powder
• ¼ tsp salt
• 6 tbsp (90ml) milk, room temperature
• 2 tbsp (30ml) water, room temperature
• 2 egg yolks
• 6 tbsp (78g) sugar
• 1 1/2 tbsp cornstarch
• 1 cup + 2 tbsp (270ml) milk
• 1 tbsp (14g) salted butter
• 1 tsp vanilla extract
• 12 oz (338g) semi-sweet chocolate chips
• 2 tbsp (30ml) light corn syrup
• 3/4 cup + 2 tbsp (210ml) heavy whipping cream

Directions

1. 
   

   Preheat oven to 350°F (176°C): Prepare a cupcake pan by lining it with cupcake liners.

   
   
2. 
   

   Cream the butter and sugar: In a large mixing bowl, cream together the butter and sugar until the mixture is light in color and fluffy, approximately 3–4 minutes. Don’t rush this step; properly creamed butter will create a light texture.

   
   
3. 
   

   Incorporate sour cream and vanilla: Add the sour cream and vanilla extract to the creamed mixture and mix until everything is well combined.

   
   
4. 
   

   Blend in egg whites: Add the egg whites in two batches, mixing well after each addition. Be sure to scrape down the bowl occasionally for full incorporation.

   
   
5. 
   

   Prepare dry ingredients: In a separate bowl, combine the flour, baking powder, and salt. In a small measuring cup, mix the milk and water together.

   
   
6. 
   

   Mix the cake batter: Add half of the dry ingredients to the wet mixture, mixing well. Follow with the milk mixture until incorporated. Finally, add the remaining dry ingredients and mix until everything is homogeneous, scraping the sides as necessary.

   
   
7. 
   

   Fill cupcake liners: Fill the liners about halfway with batter. Bake for 15-17 minutes or until a toothpick inserted into the center comes out with a few crumbs but not wet batter.

   
   
8. 
   

   Cool the cupcakes: Once baked, remove from the oven, let cool for 2-3 minutes, and then transfer to a cooling rack to cool completely.

   
   
9. 
   

   Prepare the pastry cream: In a medium-sized bowl, gently beat the egg yolks and set aside. In a large saucepan, whisk together the sugar, cornstarch, and milk until smooth. Cook over medium-high heat, stirring constantly until the mixture begins to thicken and bubble.

   
   
10. 
    

    Combine egg yolks with milk: Reduce the heat to medium and simmer for 2 minutes, then remove from heat. Gradually add a bit of the hot milk mixture into the egg yolks while whisking. This tempers the yolks, preventing them from scrambling. Once combined, pour the yolk mixture back into the saucepan.

    
    
11. 
    

    Thicken the pastry cream: Return the pan to the heat and bring to a light boil. Cook while stirring continuously for 2 more minutes until thick. Remove from the heat, then add the salted butter and vanilla extract, stirring until smooth. Let cool to room temperature.

    
    
12. 
    

    Make the chocolate ganache: While the cupcakes and cream cool, place chocolate chips in a large bowl. In a saucepan, bring the heavy cream to a boil, then pour it over the chocolate chips along with the corn syrup. Let it sit for 3–5 minutes. Whisk until melted and smooth, then refrigerate until cool and firm, about 1–2 hours.

    
    
13. 
    

    Fill the cupcakes: Once everything is cooled, use a cupcake corer or knife to cut out the centers of the cupcakes. Fill the centers with pastry cream.

    
    
14. 
    

    Top with ganache: Pipe the chocolate ganache on top of the filled cupcakes. A piping bag fitted with Ateco tip 844 or Wilton 2D/1M will allow you to create beautifully swirled decorations.

    
    
15. 
    

    Chill and serve: Refrigerate until ready to serve, but serve them closer to room temperature for the best texture. The ganache will firm up in the cold.

    
    
16. 
    

    Enjoy: These delightful cupcakes are best enjoyed within 3-4 days of baking.

    
    

How to Serve Boston Cream Pie Cupcakes

For optimal flavor, serve your Boston Cream Pie Cupcakes at room temperature. This allows the ganache to soften slightly, creating that melt-in-your-mouth experience. When plating, consider using colorful plates or adding a dusting of powdered sugar or cocoa powder for an elegant touch. To elevate your presentation further, place fresh fruit or a sprinkle of crushed nuts alongside.

These cupcakes pair wonderfully with a cup of coffee, herbal tea, or even a scoop of vanilla ice cream for that extra indulgence. They are especially perfect for birthdays, brunch gatherings, or as a decadent treat during a relaxing afternoon.

How to Store Boston Cream Pie Cupcakes

For best results, store leftover Boston Cream Pie Cupcakes in an airtight container in the refrigerator. They should remain fresh for up to 4 days. If you need to freeze them, place the cooled, filled cupcakes in a single layer in a freezer-safe container for up to 2 months. To enjoy them, thaw in the fridge overnight before serving at room temperature.

Be aware that refrigeration may cause the ganache to firm up a bit. If that happens, a quick 10-second burst in the microwave can help restore the smooth texture without drying them out.

Tips to Make Boston Cream Pie Cupcakes

1. 
   

   Room Temperature Ingredients: Ensure all your ingredients are at room temperature for better emulsification, leading to fluffier cupcakes.

   
   
2. 
   

   Cream Longer: Don’t rush the creaming step! This helps incorporate air into the batter, which makes your cupcakes light and airy.

   
   
3. 
   

   Check Doneness: Use a toothpick to test for doneness; you want it to come out with a few moist crumbs, not wet batter.

   
   
4. 
   

   Chill the Pastry Cream: Allowing the pastry cream to cool to room temperature before using helps prevent it from melting the cupcake.

   
   
5. 
   

   Cut Cleanly: Use a clean knife or a corer designed specifically for cupcakes to make filling them easier.

   
   
6. 
   

   Refrigerate the Ganache: Ensure the ganache is allowed to cool and firm up in the fridge. This makes it much easier to pipe.

   
   
7. 
   

   Play with Flavors: Add a splash of orange or almond extract to the pastry cream for a unique twist.

   
   
8. 
   

   Avoid Overfilling: When filling the cupcake liners, don’t exceed halfway to prevent overflow during baking.

   
   
9. 
   

   Layer Technique: For a beautiful finish, pipe ganache in layers, swirling more as you go up.

   
   
10. 
    

    Mix and Match: Use the same cake base but explore different fillings like fruit curd for variety at your dessert table.

    
    

Variations

1. 
   

   Vegan Boston Cream Pie Cupcakes: Replace eggs with flax eggs and use almond or coconut milk in place of dairy. Substitute vegan butter for the unsalted butter for a cruelty-free treat.

   
   
2. 
   

   Gluten-Free Boston Cream Pie Cupcakes: Use a gluten-free flour blend instead of all-purpose flour to accommodate gluten sensitivities while retaining deliciousness.

   
   
3. 
   

   Spicy Mexican Ganache: Mix a pinch of cayenne or cinnamon into the chocolate ganache for a unique flavor twist that surprises at first bite!

   
   
4. 
   

   Lemon Zest Cream: Incorporate some lemon zest into the pastry cream for a zesty punch that complements the richness wonderfully.

   
   
5. 
   

   Chocolate Lovers’ Version: Add cocoa powder to the batter for a chocolate cupcake twist, then follow the remainder of the recipe for chocolate-filled chocolate cupcakes!
