Make Ahead Tip: Cover and refrigerate the frosting (Step 7) for up to 3 days. Store cooled cupcakes airtight at room temperature for up to 1 day.
Equipment: Muffin tin with 12 (1/2-cup) cups, paper liners
Ingredient Note: Look for whole-wheat pastry flour in the natural-foods section of large supermarkets and natural-foods stores. Store in the freezer.
Tip: No buttermilk? You can make “sour milk” as a substitute: mix 1 1/2 teaspoons lemon juice or vinegar to 1/2 cup nonfat milk.
DIY Muffin Cups: Make your next batch of muffins or cupcakes the ultimate grab-and-go treat by lining your tin with muffin liners. No liners? No problem. Use 5-inch squares of parchment paper, coat each muffin cup with cooking spray, and push each square into the cups using a small can or bottle, pressing the paper up the sides. (It's OK if some of the paper is sticking out over the rim.) Fill each cup as directed.
