01 - Preheat oven to 350°F. Grease and flour two 8-inch round cake pans and line 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 mixer bowl, beat the softened butter and granulated sugar on medium-high speed until light and fluffy, about 3 minutes.
04 - Add the eggs one at a time, mixing well after each addition. Stir in the vanilla extract, fresh lemon juice, and lemon zest until combined.
05 - Add the flour mixture in three additions, alternating with the buttermilk in two additions, starting and ending with the flour. Mix until just combined.
06 - Gently fold the mashed, well-drained strawberries into the batter using a spatula. Avoid overmixing to keep the texture light.
07 - Divide the batter evenly between the two prepared pans. Smooth the tops and tap the pans gently on the counter to release any air bubbles. Bake for 30 to 35 minutes, or until a toothpick inserted in the center comes out clean.
08 - Let the cakes cool in the pans for 10 minutes, then transfer them to wire cooling racks to cool completely before frosting.
09 - Beat the softened cream cheese and butter together until creamy and smooth. Add the strawberry puree, lemon juice, and lemon zest. Gradually beat in the sifted powdered sugar and a pinch of salt until the frosting is 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 with the remaining frosting. Garnish with sliced strawberries, lemon wheels, and edible flowers as desired.
