For an extra nutty flavor, top the frosted cupcakes with chopped peanuts. Ensure your butter and cream cheese are properly softened for a smooth and lump-free frosting. Don't overmix the batter, as this can result in tough cupcakes. If you don't have sour cream, plain yogurt can be used as a substitute. For a richer flavor, use brown butter instead of regular melted butter.
