01 - Preheat your oven to 350°F. Grease and flour two 8-inch round cake pans. Line bottoms with parchment paper for easy removal.
02 - In a medium bowl, whisk together flour, baking powder, baking soda, and salt until well combined.
03 - In a large bowl, cream butter and sugar together until light and fluffy, about 3-4 minutes using an electric mixer.
04 - Add eggs one at a time, beating well after each addition. Mix in lemon zest and vanilla extract until fully incorporated.
05 - In a separate measuring cup, combine lemon juice, milk, and sour cream. Whisk until smooth.
06 - With the mixer on low speed, alternately add the flour mixture and the lemon-milk mixture to the butter mixture, beginning and ending with flour. Mix until just combined.
07 - Gently fold in the chopped strawberries using a rubber spatula. If desired, add food coloring for a pink hue.
08 - Divide batter evenly between prepared pans and smooth the tops. Bake for 28-32 minutes, or until a toothpick inserted into the center comes out clean.
09 - Let cakes cool in pans for 10 minutes, then turn out onto wire racks to cool completely before frosting.
10 - Beat butter until creamy. Add powdered sugar, lemon zest, lemon juice, salt, and 2 tablespoons cream. Beat until fluffy, 3-5 minutes, adding more cream if needed for desired consistency.
11 - Once cakes are completely cool, level tops if needed. Spread a layer of buttercream between the cakes, then frost the top and sides evenly.
12 - Decorate with fresh strawberry halves and lemon slices or zest curls as desired.
