Directions

1. Preheat oven to 325 degrees. Line cupcake pans with paper liners; set aside. In the bowl of an electric mixer fitted with the paddle attachment, combine flours, sugar, baking powder, and salt; mix on low speed until combined. Add butter, mixing until just coated with flour.
2. In a large glass measuring cup, whisk together eggs, milk, and vanilla. With mixer on medium speed, add wet ingredients in 3 parts, scraping down sides of bowl before each addition; beat until ingredients are incorporated but do not overbeat.
3. Divide batter evenly among liners, filling about 2/3 full. Bake, rotating pan halfway through, until a cake tester inserted in the center comes out clean, 17 to 20 minutes.
4. Transfer to a wire rack to cool completely. Repeat process with remaining batter. Once cupcakes have cooled, use a small offset spatula to frost tops of each cupcake. Decorate with sprinkles, if desired. Serve at room temperature.
