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, 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 in two additions, beginning and ending with the flour. Mix until just combined to avoid overworking the batter.
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, smoothing the tops. Tap the pans gently on the counter to release any trapped air bubbles. Bake for 30 to 35 minutes, or until a toothpick inserted into the center comes out clean.
08 - Let the cake layers 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 smooth and creamy. Add the strawberry puree, lemon juice, and lemon zest, mixing until incorporated. Gradually add the sifted powdered sugar and salt, beating 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 fresh strawberries, lemon wheels, and edible flowers as desired.
