# Ingredient List:

01 - 2½ cups all-purpose flour
02 - 2½ teaspoons baking powder
03 - ½ teaspoon salt
04 - 1 cup unsalted butter, softened
05 - 2 cups granulated sugar
06 - 4 large eggs, room temperature
07 - 1 tablespoon pure vanilla extract
08 - 1 cup whole milk, room temperature

→ For the Buttercream

09 - 1½ cups unsalted butter, softened
10 - 6 cups powdered sugar, sifted
11 - ¼ cup whole milk
12 - 2 teaspoons pure vanilla extract
13 - Food coloring (pink, yellow, green, or as desired)

# How to Make:

01 - Preheat oven to 350°F. Grease a 9x13-inch baking pan and line with parchment paper.
02 - In a medium bowl, whisk together flour, baking powder, and salt.
03 - In a large bowl, beat butter and sugar with an electric mixer until light and fluffy, approximately 3 minutes.
04 - Add eggs one at a time, mixing well after each addition. Mix in vanilla extract.
05 - Add flour mixture in three parts, alternating with milk, beginning and ending with flour. Mix until just combined without overmixing.
06 - Pour batter into prepared pan and smooth the top with a spatula.
07 - Bake for 28 to 32 minutes, or until a toothpick inserted in the center comes out clean.
08 - Let cake cool in pan for 10 minutes, then turn out onto a wire rack to cool completely.
09 - Beat butter until creamy. Gradually add powdered sugar, alternating with milk, beating until smooth and fluffy. Mix in vanilla.
10 - Divide buttercream into bowls and tint portions with food coloring for flowers and leaves.
11 - Spread a generous layer of plain buttercream over cooled cake as the base layer.
12 - Fill piping bags fitted with flower and leaf tips with colored buttercream. Pipe flowers and leaves decoratively across the cake, focusing on corners and edges.
13 - Optionally, pipe a cross or add First Communion text with a small round piping tip.

# Expert Suggestions:

01 -
  • The vanilla sponge stays incredibly moist for days, which means you can actually bake it ahead without stress.
  • Hand-piped flowers turn a simple cake into something that looks like you spent hours at a pastry school, but honestly takes about twenty minutes of piping once you get the hang of it.
02 -
  • Overmixing the batter after adding flour will develop gluten and make your cake dense and tough instead of tender—mix just until you don't see flour streaks anymore.
  • Gel food coloring is the game-changer for piping; liquid coloring thins out buttercream and makes it impossible to pipe clean flowers.
03 -
  • Room temperature ingredients are everything in this recipe—cold eggs, cold butter, and cold milk will fight you the whole way, so take thirty minutes to let them warm up before you start.
  • If your piped flowers aren't cooperating, the buttercream is probably too warm; pop it in the refrigerator for ten minutes and try again with a firmer consistency.
