Tips for Perfect Boston Cream Cupcakes

Use Room Temperature Ingredients

Butter, eggs, and milk mix more smoothly when they are at room temperature.

Don’t Overfill the Cupcake Liners

Two-thirds full is the ideal amount to ensure cupcakes bake evenly without overflowing.

Chill the Custard

Pastry cream needs time to thicken properly in the refrigerator before filling the cupcakes.

Pipe the Filling for Cleaner Results

Using a piping bag gives a neat and bakery-style finish.

Frequently Asked Questions

Can I make them ahead of time?

Yes. Bake the cupcakes one day ahead and store them covered. Fill and top them with ganache before serving.

Can I use pudding instead of pastry cream?

Yes, instant vanilla pudding works as a quicker filling alternative.

Why did my custard turn lumpy?

This usually happens if the heat is too high. Cook pastry cream slowly while whisking constantly.
