Ingredients
Method
Preparation
- Preheat your oven to 350°F (177°C) and line a 12-count muffin pan with cupcake liners.
- Process 1/2 cup of the chopped strawberries until chunky, not completely smooth, and set aside. Reserve 3/4 cup chopped strawberries for folding into the batter.
- In a bowl, whisk together the cake flour, baking powder, and salt. Set aside.
Making the Batter
- In another bowl, cream the softened butter and granulated sugar until light and fluffy, about 3 minutes. Scrape the bowl as needed.
- Add the egg, the two egg whites, and 2 teaspoons vanilla extract to the creamed butter and sugar, mixing until combined.
- Beat in the 1/2 cup full-fat sour cream until the mixture is smooth.
- Gradually mix in half of the dry ingredients and half of the 1/2 cup whole milk until just combined. Repeat with the remaining dry ingredients and milk, mixing on low speed to avoid overworking the batter.
- Gently fold in the reserved 3/4 cup chopped strawberries so they are evenly distributed but not crushed.
Baking
- Fill the cupcake liners about 3/4 full with batter. Bake for 21 to 24 minutes, or until a toothpick inserted in the center comes out clean.
- Let the cupcakes cool in the pan for 5 to 10 minutes before transferring to a wire rack to cool completely.
- Do not frost warm cupcakes or the buttercream will melt.
Making the Buttercream
- Process the 1 cup freeze-dried strawberries into a fine powder.
- Beat the softened 3/4 cup unsalted butter until creamy, then gradually add the 3 and 1/2 cups confectioners' sugar.
- Add the strawberry powder, 1/4 cup heavy cream or whole milk, 1 teaspoon vanilla extract, and a pinch of salt, beating until fluffy and smooth. Adjust cream or sugar to reach your desired piping consistency.
Frosting
- Frost the cooled cupcakes with the strawberry buttercream and optionally garnish with fresh strawberry slices.

Notes
Use ripe strawberries for the puree and the pieces folded into the batter. Store frosted cupcakes in an airtight container in the refrigerator for up to 3 days. Unfrosted cupcakes freeze well; wrap cooled cupcakes individually and freeze for up to 2 months. For variations, increase the amount of freeze-dried strawberry powder or add a bit more chopped fresh strawberries for extra texture.
