# 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 batter, then the milk, followed by the remaining flour. Mix gently after each addition until just combined, avoiding overmixing.
06 - Spread batter evenly onto the prepared baking sheet. Bake for 18 to 22 minutes until a toothpick inserted in the center emerges clean.
07 - Allow the cake to cool completely. Using a 2.5 to 3 inch round cutter, cut out 12 circles from the cake, re-rolling scraps as needed.
08 - Beat softened butter until creamy. Gradually add powdered sugar, vanilla extract, salt, and 1 tablespoon milk. Continue beating until light and fluffy, adding more milk if necessary. Tint with pastel food coloring if desired.
09 - Place one cake round on a serving plate, spread with buttercream layer, top with second cake round, and add another thin buttercream layer. Repeat with remaining cake rounds to create 6 mini layer cakes.
10 - Top each mini cake with additional buttercream and artfully arrange edible flowers on the surface.
11 - Refrigerate the completed mini cakes for 15 minutes to set the frosting and achieve optimal texture.

# Tips for Success:

01 -
  • Six individual cakes mean everyone gets their own moment to feel celebrated, no sharing required.
  • The lemon zest brightens the vanilla sponge in a way that tastes like spring actually tastes.
  • Edible flowers transform buttercream into something that looks impossible but tastes completely natural.
  • These come together faster than you'd expect, and they're forgiving enough for a first attempt.
02 -
  • Room temperature ingredients are the difference between a silky, even batter and one that looks broken and grainy; pull everything out an hour ahead.
  • Overmixing the batter after you add flour develops gluten and makes your cakes tough instead of tender, so stir gently and stop as soon as you don't see streaks of flour.
  • Edible flowers wilt quickly, so decorate these cakes no more than two hours before serving, or the petals will look sad and droopy.
  • If your flowers arrived in water or florist foam, rinse them gently and pat completely dry before placing them on the buttercream, or they'll slide off.
03 -
  • Brush each cake layer with a light citrus syrup before frosting for extra moisture and a subtle flavor boost that makes people wonder what you did differently.
  • If your buttercream seems too soft, chill it for ten minutes between assembly steps so it holds its shape instead of melting into the cake.
  • Buy your edible flowers the day before and store them in the refrigerator between damp paper towels so they stay perky and hydrated until you need them.
