Red Velvet Cupcakes with Cream Cheese Frosting

Why This Red Velvet Cupcakes with Cream Cheese Frosting Works

In the oven, the baking soda and buttermilk react and puff up the batter, so the cupcakes rise instead of staying dense. A little cocoa and the acid from the vinegar and buttermilk keep the crumb soft and fine, so each cupcake bites cleanly instead of crumbling. Because the recipe uses oil instead of butter in the batter, the fat stays liquid even after the cupcakes cool, so they stay moist for longer and don’t dry out as fast.

As the cupcakes bake, the egg sets and gives the batter enough structure to hold the air bubbles in place. Sugar melts and spreads through the batter, then firms back up as it cools, which keeps the texture tender. Once out of the oven, cooling on a rack lets steam escape so the tops don’t get soggy.

For the frosting, soft cream cheese and butter beat together and trap tiny air pockets. Powdered sugar thickens that mixture and makes it sturdy enough to sit on top of the cupcakes without sliding off, while still staying smooth and creamy.

Mistakes To Avoid

Overbaking the cupcakes even by a few minutes can dry them out. The tops turn a bit hard, the crumb becomes tight instead of soft, and the cupcakes taste stale and crumbly instead of moist and tender.

Mixing the batter too long after the wet and dry ingredients are combined makes the cupcakes dense. The flour soaks up more liquid and the batter loses air, so the cupcakes rise less and end up heavy instead of light.

Frosting warm cupcakes causes the cream cheese frosting to loosen and slide off. The butter and cream cheese start to melt, the frosting turns runny, and it won’t hold a nice swirl or stay in place.

Using cream cheese or butter that is still cold for the frosting often leaves small lumps. The fat doesn’t blend smoothly with the sugar, so the frosting looks grainy and can pipe unevenly on top of the cupcakes.
