# Steps:
01 - Preheat oven to 350°F. Grease and line three 8-inch round cake pans with parchment paper.
02 - In a medium bowl, whisk together flour, baking powder, and salt.
03 - In a large bowl, beat softened butter and granulated sugar until light and fluffy, approximately 3 to 4 minutes.
04 - Add eggs one at a time to the butter mixture, beating well after each addition. Mix in vanilla extract.
05 - Alternately add flour mixture and milk to the butter mixture, beginning and ending with flour. Mix until just combined.
06 - Divide batter evenly among prepared pans. Bake for 25 to 30 minutes until a toothpick inserted in the center comes out clean. Cool in pans for 10 minutes, then transfer to wire racks to cool completely.
07 - Beat softened butter until creamy. Gradually add powdered sugar, beating until smooth. Mix in lemon juice, lemon zest, and enough milk to achieve spreadable consistency.
08 - Level cooled cake layers if necessary. Place one layer on a serving plate. Spread generously with lemon frosting. Repeat with remaining layers, then frost top and sides smoothly.
09 - Heat heavy cream until just simmering without boiling. Pour over white chocolate in a heatproof bowl. Let sit 2 minutes, then stir until smooth. Tint with gel food coloring if desired. Cool until slightly thickened but still pourable.
10 - Using a spoon or squeeze bottle, gently drip white chocolate ganache around the edge of the cake, allowing it to run down the sides. Pour remaining ganache on top and spread gently.
11 - Decorate the cake top with edible flowers, sprinkles, and additional lemon zest as desired.
