Lemon Cream Cupcakes

These lemon cupcakes get their incredibly moist, dense crumb from a full two cups of sour cream in the batter. That’s not a typo. The sour cream adds richness and tang that keeps these cupcakes soft for days, while the lemon zest delivers bright citrus in every bite.

The batter is intentionally thick, almost like a pound cake consistency. That density is a feature, not a problem. Thick batter means tall, domed cupcakes that don’t collapse or crater in the center. Fill each cup with a quarter-cup measure for consistent results.

The lemon buttercream frosting doubles down on the citrus with both lemon juice and lemon zest. Fresh juice gives it a sharp tang that cuts through the powdered sugar sweetness, and the zest adds those fragrant oils that your nose picks up before your taste buds do.

Chef Tips

• Cream the butter and sugar thoroughly, at least 3-4 minutes. This is a dense batter and the creaming step is where all the lift comes from.
• Add eggs one at a time and beat well between each. Rushing dumps too much liquid into the batter at once and it can curdle.
• Alternate adding dry ingredients and sour cream in three additions. This keeps the batter emulsified and prevents overmixing the flour, which toughens the crumb.
• Cool cupcakes completely before frosting. Warm cupcakes melt the buttercream and it slides right off.

Variations

• Add a tablespoon of limoncello to the frosting for an adult lemon kick.
• Fill each cupcake with a spoonful of lemon curd after baking for a surprise citrus center.
• Top with fresh raspberries or blueberries for a color contrast and fruity pop.
