What You’ll Need

Before we dive into the cooking process, let’s take a look at the ingredients you’ll need to create these scrumptious cupcakes:

  • 6 tbsp (84g) unsalted butter, room temperature (I use Challenge Butter)
  • 3/4 cup (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 (for the pastry cream)
  • 1 1/2 tbsp cornstarch
  • 1 cup + 2 tbsp (270ml) milk (for the pastry cream)
  • 1 tbsp (14g) salted butter (for the pastry cream)
  • 1 tsp vanilla extract (for the pastry cream)
  • 12 oz (338g) semi-sweet chocolate chips
  • 2 tbsp (30ml) light corn syrup
  • 3/4 cup + 2 tbsp (210ml) heavy whipping cream

Substitutions/Notes: Consider using dairy-free butter and alternative milk for a vegan version. You can swap the semi-sweet chocolate for dark chocolate if you prefer a richer flavor.

Directions to Follow

Follow these organized steps and see how effortless it is to make Boston Cream Pie Cupcakes!

  1. Preheat your oven to 350°F (176°C) and line a cupcake pan with cupcake liners.
  2. In a large mixing bowl, cream the butter and sugar together until light and fluffy, about 3-4 minutes. Don’t rush this step; it’s essential for the right texture.
  3. Mix in the sour cream and vanilla until well combined.
  4. Gradually add the egg whites in two batches, mixing thoroughly after each addition. Scrape the bowl’s sides as needed.
  5. In a separate bowl, combine dry ingredients. In a small measuring cup, mix the milk and water.
  6. Add half of the dry mixture to the batter and combine, then mix in the milk mixture. Finish with the remaining dry ingredients and stir until fully incorporated.
  7. Fill each cupcake liner halfway and bake for 15-17 minutes, until a toothpick inserted comes out with a few crumbs.
  8. Cool the cupcakes for 2-3 minutes in the pan, then transfer them to a wire rack to cool completely.
  9. While the cupcakes cool, make the pastry cream. Beat egg yolks in a medium bowl and set aside.
  10. In a large saucepan, mix sugar, cornstarch, and milk until smooth. Cook over medium-high heat, stirring continuously until it thickens and bubbles.
  11. Reduce to medium heat and simmer for 2 minutes. Remove from heat.
  12. Take a little of the hot mixture and whisk it into the egg yolks, then return everything back to the saucepan. This technique prevents cooking the yolks.
  13. Return to heat, bring to a light boil, and simmer for another 2 minutes, stirring all the while.
  14. Remove from heat, add butter and vanilla, and stir until smooth. Allow to cool to room temperature.
  15. For the chocolate ganache, place the chocolate chips and corn syrup in a bowl. Bring the heavy cream to a boil and pour it over the chocolate. Let it sit for 3-5 minutes before whisking until smooth. Refrigerate until cool and firm, around 1-2 hours.
  16. Once everything has cooled, use a cupcake corer (or a knife) to remove the centers of the cupcakes.
  17. Fill the centers with pastry cream.
  18. Top each cupcake with chocolate ganache, and for a decorative touch, pipe roses using a piping tip.
  19. Refrigerate until ready to serve; they are best enjoyed at room temperature.

Best Ways to Enjoy It

These Boston Cream Pie Cupcakes shine on their own, but why not elevate the experience? Serve them alongside a steaming cup of coffee or a refreshing glass of milk for the ultimate treat. You can even accompany them with fresh fruit like berries or a scoop of vanilla ice cream for an extra indulgent moment.

Keeping Leftovers Fresh

If you have any cupcakes left (which is unlikely!), store them in an airtight container in the refrigerator. They’ll stay fresh for about 3-4 days. For longer storage, consider freezing them without the ganache; simply remove the centers, fill with pastry cream, and wrap tightly. Thaw in the fridge overnight before serving, then top with ganache.

Extra Advice

To ensure perfect cupcakes, remember:

  • Don’t overmix the batter after adding flour; this could lead to dense cupcakes.
  • Allow your butter to come to room temperature for the best creaming results.
  • For even baking, make sure to rotate the cupcake pan halfway through the baking time.

Creative Twists

Feel free to get creative! You can add flavors like almond extract in the batter for a nuttier taste or even mix in some chocolate chips. For a tropical twist, consider using coconut cream instead of milk in your pastry cream. The possibilities are endless!

Your Questions Answered

Q: Can I make these ahead of time?
A: Absolutely! You can bake the cupcakes and prepare the pastry cream a day in advance. Just store them separately until you’re ready to assemble.

Q: Is there a way to modify this recipe for dietary restrictions?
A: Yes! You can use dairy-free butter and milk alternatives to make these cupcakes dairy-free. Also, replacing the sugar with a suitable sweetener can make them diabetic-friendly.

Q: What should I do if my pastry cream doesn’t thicken?
A: If your pastry cream doesn’t thicken, ensure you’ve cooked it long enough to reach the boiling point and allow the cornstarch to activate. Keep stirring continuously, and it will eventually thicken.

These Boston Cream Pie Cupcakes are not just a treat; they are a celebration. Perfect for any occasion, this dessert will leave you, and everyone you share it with, wanting more! Enjoy your baking adventure!
