We found that Carnation instant nonfat dry milk is more finely ground and dissolves in the cake batter better than other brands with larger granules. This mix also makes 24 cupcakes. Place paper liners in pans and fill each cup 2/3 full. Bake at 350 degrees F until golden, puffed and a toothpick comes out clean, 18 to 20 minutes, rotating the pans halfway through. Cool completely before frosting as desired.
