Ingredients:
- 1 lb fresh strawberries, hulled
- 1 tbsp lemon juice
- 1 tbsp granulated sugar
- 3 cups cake flour, sifted
- 1.5 cups granulated sugar
- 1 tbsp baking powder
- 1/2 tsp salt
- 1 cup unsalted butter, softened to 65°F
- 4 large eggs, room temperature
- 1/2 cup whole milk, room temperature
- 1/3 cup full-fat sour cream
- 1.5 cups unsalted butter, slightly firm (for buttercream)
- 5 cups powdered sugar, sifted
- 1/4 tsp salt
Instructions:
- Puree 1 lb fresh strawberries with 1 tbsp lemon juice and 1 tbsp sugar. Simmer in a saucepan over medium heat for 12-15 minutes until reduced to exactly 1/2 cup. Let it cool completely.
- Whisk together 3 cups sifted cake flour, 1.5 cups sugar, 1 tbsp baking powder, and 1/2 tsp salt in your mixer bowl.
- Add 1 cup softened butter to the dry ingredients. Mix on low speed until the mixture looks like coarse sand.
- Whisk 4 eggs, 1/2 cup milk, and 1/3 cup sour cream together. Slowly pour half of this into the flour mixture and beat for 1 minute until the batter looks pale and fluffy.
- Fold in the cooled strawberry reduction and the remaining egg mixture. Mix on medium speed for 30 seconds until the color is a uniform, soft pink.
- Divide the batter between two greased and lined pans. Bake at 350°F for 30-35 minutes until the edges pull away from the pan and the center springs back.
- Let the cakes rest in the pans for 10 minutes, then invert onto a wire rack. Cool completely.
- Beat 1.5 cups firm butter with 5 cups powdered sugar and 1/4 tsp salt. Add 2 tablespoons of any leftover strawberry reduction until the frosting is silky and holdable.
