- Preheat oven to 350 degrees. Line standard muffin tins with paper liners. Whisk dry ingredients in a large bowl. Cream butter and sugar with a mixer until light and fluffy. Add eggs, 1 at a time, beating after each addition.
- Reduce speed to low. Mix any remaining wet ingredients in a bowl if needed. Add dry ingredients to butter mixture in 3 additions, alternating with wet ingredients and ending with dry. Scrape sides of bowl. Divide batter among muffin cups, filling each 2/3 full.
- Bake cupcakes until testers inserted into centers come out clean, about 20 minutes. Let cool in tins on wire racks. Cupcakes will keep, covered, for up to 3 days, unless otherwise noted.
