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 the 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 — do not overmix.
06 - Gently fold the well-drained mashed strawberries into the batter using a spatula, taking care not to overmix.
07 - Divide the batter evenly between the two prepared cake pans. Smooth the tops and tap the pans gently on the counter to release any trapped air bubbles. Bake for 30–35 minutes, or until a toothpick inserted into the center comes out clean.
08 - Let the cakes 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 light, smooth, and fluffy.
10 - Once the cake layers are completely cool, spread an even layer of frosting between the two layers, then cover the top and sides of the cake with the remaining frosting. Garnish with sliced strawberries, lemon wheels, and edible flowers as desired.
