Expert Advice for the Best Moist Vanilla Cupcakes
Use room temperature ingredients to ensure the batter blends evenly and bakes uniformly. Donโt overmix once the wet meets dry to keep the cupcakes tender. Vanilla bean paste adds visual appeal and boosts the vanilla flavor significantly. When baking, check at the 18-minute markโcupcakes should spring back lightly to the touch.

Storing Your Moist Vanilla Cupcakes
Best Ways to Keep Moist Vanilla Cupcakes Fresh

Frequently Asked Questions
Can I use whole eggs instead of egg whites?
Yes, but using only egg whites keeps the crumb light and white. Whole eggs will make it denser and more yellow.
Whatโs the best vanilla to use?
Vanilla bean paste or pure vanilla extract are best for bold, aromatic flavor. Avoid imitation vanilla for this recipe.
Can I make the cupcakes ahead of time?
Absolutely. Bake the cupcakes a day in advance, store in an airtight container, and frost just before serving.
Why is my batter clumpy?
Thatโs normal due to the melted butter meeting cooler ingredients. It smooths out during baking.
