# Components:

→ Sheet Cake

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

→ 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 in pink, yellow, green, or desired shades

# Directions:

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 portions, 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 softened butter until creamy. Gradually add powdered sugar, alternating with milk, beating until smooth and fluffy. Mix in vanilla extract.
10 - Divide buttercream into bowls and tint portions with food coloring for flowers and leaves.
11 - Spread a generous layer of plain buttercream over the 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 or along the edges for a classic appearance.
13 - Optionally, pipe a cross or add First Communion text using a small round tip.

# Chef Secrets:

01 -
  • The buttercream pipes like butter should, creating flowers that look far more sophisticated than you'd expect from your own hands.
  • You can bake it the day before and decorate in the morning, which means less stress on the actual day.
  • Twenty servings means you're covered for a small gathering without spending hours in the kitchen.
02 -
  • Overmixing the batter is the enemy—once you can't see any streaks of flour, stop mixing, even if it looks slightly rough; the rest of the mixing will happen in the oven as the cake rises.
  • Gel food coloring makes the difference between buttercream flowers that look homemade and ones that look like they came from a bakery, so it's worth keeping a set on hand.
03 -
  • If your kitchen is warm, refrigerate the buttercream-filled piping bag for five minutes between flowers so the frosting stays firm enough to hold its shape.
  • The key to flowers that look intentional is accepting that they don't need to be perfect—slight asymmetry reads as delicate and handmade rather than commercial.
