👩‍🍳 Instructions

Step 1: Bake the Cupcakes

1. Preheat the oven to 350°F (175°C).
2. Line a 12-cup muffin pan with cupcake liners.
3. In a bowl, whisk together the flour, baking powder, and salt.
4. In another bowl, beat the butter and sugar until light and fluffy (about 3 minutes).
5. Add the eggs one at a time, then mix in the vanilla.
6. Alternately add the dry ingredients and milk, beginning and ending with the dry ingredients.
7. Fill each cupcake liner about ⅔ full.
8. Bake for 18–20 minutes, or until a toothpick inserted into the center comes out clean.
9. Cool completely on a wire rack.

Step 2: Make the Pastry Cream

1. Heat the milk in a saucepan over medium heat until steaming (do not boil).
2. In a bowl, whisk together the egg yolks, sugar, cornstarch, and salt until smooth.
3. Slowly pour the warm milk into the egg mixture while whisking constantly.
4. Return the mixture to the saucepan.
5. Cook over medium heat, whisking continuously, until thickened (about 3–5 minutes).
6. Remove from the heat and stir in the butter and vanilla.
7. Transfer to a bowl, press plastic wrap directly onto the surface, and refrigerate for at least 1 hour.

Step 3: Fill the Cupcakes

1. Use a small knife or cupcake corer to remove a small piece from the center of each cupcake.
2. Spoon or pipe the chilled pastry cream into each cupcake.
3. Replace the tops if desired, trimming them to fit.

Step 4: Make the Ganache

1. Heat the heavy cream until it just begins to simmer.
2. Pour it over the chocolate chips.
3. Let sit for 2 minutes, then stir until smooth.
4. Stir in the butter, if using.

Step 5: Decorate

1. Spoon or dip the tops of the filled cupcakes into the chocolate ganache.
2. Allow the ganache to set for 15–20 minutes before serving.

💡 Tips for Success

• Bring butter, eggs, and milk to room temperature before baking.
• Don’t overmix the cupcake batter to keep the cupcakes soft.
• Chill the pastry cream completely before filling.
• Let the ganache cool slightly so it thickens enough to stay on the cupcakes.
• Use a piping bag for neat, evenly filled cupcakes.

❓ Frequently Asked Questions

Can I make Boston Cream Cupcakes ahead of time?

Yes. Bake the cupcakes and prepare the pastry cream 1 day in advance. Store them separately in the refrigerator, then fill and top with ganache before serving for the freshest results.

Can I use instant vanilla pudding instead of pastry cream?

Yes. Instant vanilla pudding is a quick alternative, though homemade pastry cream offers a richer flavor and smoother texture.

Why did my pastry cream become lumpy?

This usually happens if it isn’t whisked constantly while cooking. If needed, strain the pastry cream through a fine-mesh sieve before chilling for a silky-smooth filling.

Can I use milk chocolate for the ganache?

Absolutely. Milk chocolate creates a sweeter topping, while dark chocolate gives a richer, more balanced flavor.

How do I keep the cupcakes moist?

Store them in an airtight container in the refrigerator and let them sit at room temperature for 15–20 minutes before serving for the best flavor and texture.
