Really Real Strawberry Cupcakes

Step 1
Preheat oven to 350 degrees F (175 degrees C). Line muffin tins with 20 cupcake liners (for mini cupcakes, line 72 mini muffin tins).

Step 2
Grind strawberries into a fine powder using a coffee grinder or food processor. Whisk strawberry powder, all-purpose flour, cake flour, baking powder, baking soda, and salt together in a bowl.

Step 3
Beat butter and sugar in a bowl with an electric mixer until light and fluffy. Mixture should be noticeably lighter in color. Add room-temperature eggs one at a time, allowing each egg to blend into butter mixture before adding the next. Beat in vanilla extract.

Step 4
Stir flour mixture, alternately with the milk, into butter mixture until just incorporated. Fill lined tins with cupcake batter.

Step 5
Bake in preheated oven until cupcakes spring back when gently touched with a fingertip or a toothpick inserted in the center comes out clean, 16 to 18 minutes for regular cupcakes, 8 to 10 minutes for mini cupcakes.
