Strawberry Cupcakes with Strawberry Buttercream

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 and white, 1 at a time, beating after each addition.

Reduce speed to low. Mix milk and vanilla in a bowl. Add dry ingredients to butter mixture in 3 additions, alternating with wet ingredients and ending with dry. Scrape sides of bowl. Stir chopped strawberries into batter. 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. (Unfrosted cupcakes will keep, covered, for up to 3 days, unless otherwise noted.) Once cupcakes are cool, frost tops with strawberry buttercream. Frosted cupcakes will keep, covered and refrigerated, for up to 2 days. Top with a strawberry just before serving.
