# How-To Steps:

01 - Preheat oven to 350°F. Line a 9x13 inch rimmed baking sheet with parchment paper and lightly grease the surface.
02 - In a medium bowl, whisk together flour, baking powder, and salt until evenly distributed.
03 - In a large bowl, beat softened butter and granulated sugar together until pale and fluffy, approximately 3 minutes.
04 - Add eggs one at a time to the butter mixture, beating well after each addition. Mix in vanilla extract and lemon zest until fully combined.
05 - Add half the flour mixture to the egg mixture, then add the milk, followed by the remaining flour. Mix gently after each addition until just combined, being careful not to overmix.
06 - Spread batter evenly onto the prepared baking sheet. Bake for 18 to 22 minutes, or until a toothpick inserted in the center comes out clean.
07 - Allow cake to cool completely. Using a 2.5 to 3 inch round cutter, cut out 12 circles from the cake sheet, re-rolling scraps as needed.
08 - Beat softened butter until creamy. Gradually add powdered sugar, vanilla extract, and salt. Beat until light and fluffy. Add milk one tablespoon at a time as needed to achieve desired consistency. Tint with food coloring if desired.
09 - Place one cake round on a serving plate. Spread with a layer of buttercream. Top with a second cake round and apply another thin layer of buttercream on top.
10 - Top each mini cake with additional buttercream and arrange edible flowers artfully on the surface. Repeat assembly process with remaining cake rounds to create 6 mini layer cakes.
11 - Refrigerate assembled cakes for 15 minutes before serving to set the frosting and enhance texture.

# Helpful Hints:

01 -
  • They look like you spent hours in a patisserie, but they come together in an afternoon with zero pretension.
  • The combination of tender cake and fluffy buttercream feels indulgent without being heavy, making them perfect for any birthday moment.
  • You get to personalize each one—different flower arrangements, buttercream colors, your own edible garden on a plate.
02 -
  • Room temperature ingredients are not optional—cold eggs and milk will cause the batter to separate and you will end up with a grainy, sad cake.
  • Edible flowers must come from a trusted source because your regular garden flowers are probably treated with pesticides that have no business on food.
  • Do not skip the chilling step; those fifteen minutes transform the cakes from delicate to sturdy in the best possible way.
03 -
  • Invest in a good offset spatula—it makes spreading buttercream on these delicate cakes infinitely easier and prettier.
  • If your buttercream breaks or looks grainy while mixing, you likely added cold milk; warm it slightly and beat again until it comes back together.
