Simple first communion cake (Printable)

Tender vanilla sheet cake with creamy buttercream and floral decoration, perfect for festive occasions.

# What You Need:

→ 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 Frosting

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)

# 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 until evenly distributed.
03 - In a large bowl, beat softened butter and granulated sugar with an electric mixer until light and fluffy, approximately 3 minutes.
04 - Add eggs one at a time, mixing well after each addition. Blend in vanilla extract until fully combined.
05 - Add flour mixture in three alternating additions with milk, starting and finishing with flour. Mix until just combined; do not overmix.
06 - Pour batter into prepared pan and smooth the top surface with a spatula.
07 - Bake for 28–32 minutes, or until a toothpick inserted in the center emerges clean.
08 - Allow cake to 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 separate bowls and tint portions with food coloring for flowers and leaves.
11 - Spread a generous layer of plain buttercream evenly 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 and edges for a classic presentation.
13 - Optionally pipe a cross or First Communion text using a small round tip for personalization.

# Expert Advice:

01 -
  • The cake stays impossibly moist for days, which means you can actually bake it ahead without stress.
  • Piped buttercream flowers look showstopping but don't require fancy decorating skills—just a steady hand and patience.
  • One sheet feeds twenty people without needing multiple layers or fussy assembly.
02 -
  • Don't skip bringing ingredients to room temperature—cold eggs and butter won't emulsify properly, and cold milk will cause the batter to seize up.
  • Overmixing the final batter is the silent killer of tender cake; mix only until the streaks of flour disappear, then stop.
  • Gel food coloring is non-negotiable if you want buttercream that pipes cleanly without turning runny or pale.
03 -
  • If your buttercream breaks or looks grainy, it's usually too cold; let it sit for a few minutes or gently warm the bowl over a pot of warm water, stirring constantly.
  • Buy a few extra piping tips and practice on the side of the frosted cake before committing to the front—mistakes blend easily into the overall design.
