Golden memories: Smelling sweetly of butter, sugar and vanilla, these classic little cakes bring you right back to when you were a kid and Mom baked you birthday cupcakes.
Ensure all cold ingredients, especially eggs and milk, are at room temperature for better emulsification and a finer crumb. When adding the melted butter, pour it in a slow, steady stream while the mixer is running to prevent the batter from breaking. Be careful not to overmix the batter once the flour is added, as this develops gluten and can lead to tough cupcakes. Cool cupcakes completely on a wire rack before frosting; frosting warm cupcakes will cause the frosting to melt.
