01 - Preheat oven to 350°F (175°C). Grease and flour two 8-inch round cake pans and line the bottoms with parchment paper.
02 - In a medium bowl, whisk together the all-purpose flour, baking powder, baking soda, and salt until evenly distributed.
03 - In a large mixing bowl, beat the softened butter and granulated sugar using an electric mixer until light and fluffy, approximately 3 minutes.
04 - Add the eggs one at a time, mixing thoroughly after each addition. Blend in the vanilla extract, fresh lemon juice, and lemon zest.
05 - Add the flour mixture in three additions, alternating with the buttermilk, beginning and ending with the flour. Mix until just combined to avoid developing excess gluten.
06 - Gently fold the well-drained mashed strawberries into the batter using a spatula. Take care not to overmix, which can toughen the crumb.
07 - Divide the batter evenly between the two prepared cake pans. Smooth the tops and tap the pans gently on the counter to release trapped air bubbles. Bake for 30–35 minutes, or until a toothpick inserted into the center comes out clean.
08 - Allow the cakes to cool in their pans for 10 minutes, then transfer to wire cooling racks to cool completely before frosting.
09 - Beat the softened cream cheese and butter together until creamy and smooth. Add the strained strawberry purée, lemon juice, and lemon zest. Gradually beat in the sifted powdered sugar and salt until the frosting is smooth, fluffy, and spreadable.
10 - Once the cake layers are completely cool, spread frosting evenly between the layers and over the top and sides of the cake. Garnish with sliced fresh strawberries, lemon wheels, and edible flowers as desired.
