Simple First Communion Sheet (Printable)

Tender vanilla sheet cake adorned with creamy buttercream and delicate piped flowers, perfect for festive occasions.

# What You Need:

→ Sheet Cake

01 - 2 1/2 cups all-purpose flour
02 - 2 1/2 teaspoons baking powder
03 - 1/2 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 - 1 1/2 cups unsalted butter, softened
10 - 6 cups powdered sugar, sifted
11 - 1/4 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.
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; avoid overmixing.
06 - Pour batter into prepared pan and smooth the top with a spatula.
07 - Bake for 28–32 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 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 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 presentation.
13 - Optionally, pipe a cross or add First Communion text using a small round tip.

# Expert Suggestions:

01 -
  • The cake stays impossibly moist for days, so you can bake it ahead and focus on decorating when you're calm and ready.
  • Buttercream flowers look professional but genuinely anyone can pipe them—I've seen eight-year-olds nail it.
  • Feeds a crowd without requiring you to juggle multiple pans or complicated techniques.
02 -
  • Room temperature ingredients are not a suggestion—they blend together smoothly and create a better texture than cold ingredients pulled straight from the fridge.
  • Overmixing the batter once the flour is added will develop gluten and create a tough, dense cake; mix just until you don't see streaks of flour anymore.
  • Gel food coloring is a game-changer because it tints buttercream without watering it down like liquid colors do.
03 -
  • Sift powdered sugar before measuring and after opening the bag—even old powdered sugar can have settled clumps that grit up your buttercream.
  • If buttercream seems too soft to pipe, refrigerate it for 10 to 15 minutes; if it's too stiff and cracking, let it sit at room temperature for a few minutes and re-beat it briefly.
