Instructions
Step 1: Make the Strawberry Reduction
- Puree the Strawberries: Place fresh strawberries in a blender or food processor and blend until smooth.
- Cook Down the Puree: Pour the puree into a saucepan over medium heat. Simmer for 25-30 minutes, stirring occasionally, until the mixture has reduced by about half. You should have approximately 1/2 cup of strawberry reduction.
- Cool the Reduction: Remove from heat and allow the strawberry reduction to cool completely before using it in the cake and frosting.
Step 2: Prepare the Cake Batter
- Preheat the Oven: Set to 350°F (177°C). Grease and lightly flour three 9-inch round cake pans or line with parchment paper.
- Mix Dry Ingredients: In a medium bowl, whisk the cake flour, baking powder, baking soda, and salt.
- Cream Butter and Sugar: In a large bowl, beat the butter and sugar on high speed until light and fluffy, about 2 minutes.
- Add Egg Whites and Sour Cream: Beat in the egg whites on medium speed until combined, then add the sour cream and vanilla extract, scraping the sides of the bowl as needed.
- Incorporate Strawberry Reduction and Milk: Reduce speed to low. Add half of the strawberry reduction, mixing until just combined, followed by the milk. Then add the remaining flour mixture and mix until fully incorporated.
- Bake the Cake: Divide batter evenly among prepared pans and bake for 23-26 minutes, or until a toothpick inserted in the center comes out clean. Allow cakes to cool completely.
Step 3: Make the Strawberry Frosting
- Beat Butter: In a large bowl, beat the butter on high speed until creamy, about 2 minutes.
- Add Confectioners’ Sugar: Gradually add confectioners’ sugar and mix on low until combined.
- Incorporate Strawberry Reduction: Add 1/4 cup of the cooled strawberry reduction, heavy cream, vanilla, and salt. Beat on high until frosting is smooth and creamy, about 3 minutes. Add extra confectioners’ sugar if a thicker consistency is desired.
Step 4: Assemble the Cake
- Layer the Cake: Place one cake layer on a serving plate and spread about 1 cup of frosting on top. Repeat with the second and third layers.
- Frost the Outside: Use remaining frosting to coat the top and sides of the cake. For decoration, use fresh strawberries or additional strawberry powder for garnish.
- Serve and Enjoy! This cake tastes best served at room temperature. Refrigerate leftovers for up to 5 days.
Tips for Perfect Strawberry Cake
- Use Freeze-Dried Strawberry Powder: For an extra boost of strawberry flavor, add freeze-dried strawberry powder to the batter or frosting without adding moisture.
- Achieve Vibrant Color: If you want a brighter pink hue, add a natural food color derived from beet or plant-based sources.
- Storage: This cake keeps well covered in the refrigerator for up to 5 days or frozen for up to 3 months.
