Ingredients
Method
- Place thawed or fresh strawberries in a blender and blend until smooth.
- In a medium saucepan, combine strawberry puree, sugar, lemon juice, lemon zest, and a pinch of salt. Bring to a boil.

- Reduce heat to medium-low and simmer, stirring occasionally until the mixture thickens to a consistency resembling tomato sauce (about 40-60 minutes).
- Once thickened, remove from heat and cool. You should have about 2 cups of reduction.
- Ensure all ingredients (butter, egg whites, milk, reduction) are at room temperature.
- Preheat oven to 350°F (176°C) and grease two 8-inch cake pans.
- In a medium bowl, whisk together milk, oil, strawberry reduction, strawberry emulsion, vanilla extract, lemon zest, lemon juice, and pink food coloring.
- In a separate bowl, whisk together flour, baking powder, baking soda, and salt.
- Beat butter in a stand mixer on medium speed until smooth and creamy, about 30 seconds.
- Gradually add sugar and beat until light and fluffy, about 3-5 minutes.

- Add egg whites one at a time, beating well between additions.
- Add one-third of the dry ingredients to the wet mixture, followed by one-third of the milk mixture. Mix until almost combined. Repeat two more times.
- Scrape the bowl and beat until fully incorporated.
- Divide the batter evenly between the prepared pans.

- Bake at 350°F (176°C) for 30-35 minutes, or until a toothpick comes out clean or with a few crumbs.
- Let cakes cool in the pans for 10 minutes, then flip onto wire racks to cool completely.

- Wrap cooled cakes in plastic wrap and refrigerate or freeze before assembling.
- In the bowl of a stand mixer, combine egg whites and powdered sugar. Whisk on low speed, then whip on high for 5 minutes.
- Add softened butter in chunks, whipping on high for 8-10 minutes until light and fluffy.
- Add strawberry reduction, vanilla extract, and salt, and continue whipping until fully incorporated.
- Optional: Switch to a paddle attachment and mix on low for 15-20 minutes to achieve a smooth, air-free buttercream.

Notes
Make sure to use room temperature ingredients for the best results. The strawberry reduction adds amazing flavor to both the cake and the frosting.
