# Directions:
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, baking soda, and salt. Set aside.
03 - In a large bowl, cream softened butter and granulated sugar together until light and fluffy, approximately 3 minutes.
04 - Add eggs one at a time, beating well after each addition. Mix in vanilla extract and lemon zest until combined.
05 - Add dry ingredients to the wet mixture in three additions, alternating with buttermilk. Begin and end with dry ingredients. Mix until just combined without overmixing.
06 - Divide batter evenly among prepared pans and smooth the tops. Bake for 25 to 30 minutes until a toothpick inserted in the center comes out clean.
07 - Cool cakes in pans for 10 minutes, then turn out onto a wire rack to cool completely.
08 - In a heatproof bowl set over a saucepan of simmering water, whisk lemon juice, zest, sugar, and egg yolks. Cook, whisking constantly, for 8 to 10 minutes until thickened. Remove from heat and whisk in cubed butter until smooth. Cool completely.
09 - Beat cold heavy cream, powdered sugar, and vanilla extract until stiff peaks form. Refrigerate until assembly.
10 - Place one cake layer on a serving platter. Spread with half the lemon curd, then a layer of whipped cream. Repeat with the second layer. Top with the third cake and a thick layer of whipped cream.
11 - Decorate with edible flowers and lemon zest curls immediately before serving.
