Whisk together:

• Flour

until light and fluffy.

Add the eggs one at a time, followed by the vanilla.

Fill each cupcake liner about ⅔ full.

Bake for 18–22 minutes, or until a toothpick inserted into the centre comes out clean.

Cool completely on a wire rack.

---

Step 4: Make the Pastry Cream

Heat the milk in a saucepan until steaming but not boiling.

In a bowl, whisk together:

• Sugar
• Egg yolks
• Cornflour
• Salt

Slowly whisk the warm milk into the egg mixture.

Return everything to the saucepan.

Cook over medium heat, whisking constantly, until thick.

Remove from the heat and stir in:

• Butter
• Vanilla extract

Transfer to a bowl, cover the surface with plastic wrap, and chill until completely cold.

---

Step 5: Fill the Cupcakes

Use a small knife or cupcake corer to remove a small section from the centre of each cupcake.

Fill each cupcake generously with the custard.

---

Pour over the chopped chocolate.

Let stand for 2 minutes, then stir until smooth and glossy.

Tips for the Best Boston Cream Cupcakes

Chill the Custard

Cold pastry cream is much easier to pipe into the cupcakes.

Don’t Overmix the Batter

Overmixing can make the cupcakes dense.

Cool Completely

Warm cupcakes can melt the pastry cream and ganache.

Use Good Chocolate

High-quality chocolate creates a smoother, richer ganache.

---

Delicious Variations

Raspberry Boston Cream

Pipe a teaspoon of raspberry jam into the centre before adding the custard.

Storage Tips

Freezer: Freeze the unfilled cupcakes for up to 3 months. Thaw completely before filling and decorating.

Because of the pastry cream filling, assembled cupcakes should not be left at room temperature for extended periods.

Common Mistakes to Avoid

Overcooking the Custard

Cook just until thickened. Overcooking may cause it to become grainy.

Filling Warm Cupcakes

Always allow the cupcakes to cool completely before adding the pastry cream.

Using Thin Ganache

Let the ganache cool slightly before topping the cupcakes so it doesn’t run off.

Overbaking

Bake only until a toothpick comes out clean to keep the cupcakes soft and moist.

Frequently Asked Questions

Can I use instant pudding instead of pastry cream?

Yes. Instant vanilla pudding works as a quicker alternative, although homemade pastry cream provides a richer flavour and smoother texture.

Can I make these ahead of time?

Yes. Bake the cupcakes and prepare the pastry cream a day in advance. Fill and top them with ganache shortly before serving.

Why is my pastry cream lumpy?

Lumps usually form if the custard cooks too quickly. Whisk constantly and strain through a fine sieve if necessary.

Can I freeze Boston Cream Cupcakes?

It’s best to freeze only the unfilled cupcakes. The pastry cream and ganache are best prepared fresh.

Can I use milk chocolate?

Absolutely. Milk chocolate creates a sweeter, creamier ganache, while dark chocolate offers a richer flavour.

Expert Tips for Bakery-Style Boston Cream Cupcakes

• Use room-temperature ingredients for a lighter, more even cupcake crumb.
• Chill the filled cupcakes for 20–30 minutes before adding the ganache to help it set neatly.
• Pipe the pastry cream generously so every bite has a creamy centre.
• Dip the tops directly into the ganache for a smooth, professional finish.
• Garnish with chocolate curls or a light dusting of cocoa powder for an elegant presentation.
