01 - Preheat oven to 350°F. Grease and flour two 8-inch round cake pans and line the bottoms with parchment paper.
02 - In a medium bowl, whisk together the 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.
05 - Add the flour mixture in three additions, alternating with the buttermilk, beginning and ending with the flour. Mix until just combined.
06 - Gently fold the well-drained mashed strawberries into the batter, being careful not to overmix.
07 - Divide the batter evenly between the 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 them to wire cooling racks to cool completely.
09 - Beat the softened cream cheese and butter together until creamy. Blend in the strawberry purée, lemon juice, and lemon zest. Gradually add the sifted powdered sugar and salt, beating until smooth and fluffy.
10 - Once the cake layers are completely cool, spread frosting between the layers and over the top and sides. Garnish with sliced strawberries, lemon wheels, and edible flowers as desired.
