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 with an electric mixer until light and fluffy, approximately 3 minutes.
04 - Add eggs one at a time, beating well after each addition. Stir in the vanilla extract, fresh lemon juice, and lemon zest until fully incorporated.
05 - Add the flour mixture in three additions, alternating with the buttermilk in two additions, beginning and ending with the flour. Mix until just combined.
06 - Gently fold the well-drained mashed strawberries into the batter using a spatula. Avoid overmixing to maintain a tender crumb.
07 - Divide the batter evenly between the two prepared cake pans, smoothing the tops. Tap 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 cakes to cool in the pans for 10 minutes, then invert onto 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, fresh lemon juice, and lemon zest. Gradually beat in the sifted powdered sugar and pinch of salt until the frosting is light and fluffy.
10 - Once the cake layers are completely cool, spread frosting evenly between the layers and over the top and sides. Garnish with sliced strawberries, lemon wheels, and edible flowers as desired.
