# How to Prepare:

01 - Preheat oven to 350°F. Grease and line three 8-inch round cake pans with parchment paper.
02 - Whisk together flour, baking powder, baking soda, and salt in a medium bowl.
03 - Beat sugar and lemon zest with butter until light and fluffy. Add eggs one at a time, beating well after each. Mix in vanilla extract.
04 - Combine milk and lemon juice in a measuring jug.
05 - Alternately add flour mixture and milk mixture to the butter mixture, beginning and ending with flour. Mix just until combined.
06 - Divide batter evenly among prepared pans. Bake for 25–30 minutes, or until a toothpick inserted in the center comes out clean. Cool in pans for 10 minutes, then turn out onto wire racks to cool completely.
07 - Combine strawberries, sugar, and lemon juice in a saucepan. Cook over medium heat, stirring, until berries release juice and soften (5–7 minutes). Stir in cornstarch slurry and cook until thickened (1–2 minutes). Cool completely.
08 - Beat butter until creamy. Gradually add powdered sugar, lemon juice, cream, vanilla, and salt. Beat until light and fluffy. Add food coloring if desired.
09 - Place one cake layer on a serving plate. Spread with half the strawberry filling. Top with second cake layer and remaining filling. Place final cake layer on top. Frost top and sides with buttercream. Decorate with fresh strawberries and lemon zest if desired.
