Ingredients

• For the Sheet Cake
  • 2 ½ cups (320 g) all-purpose flour
  • 2 ½ tsp baking powder
  • ½ tsp salt
  • 1 cup (225 g) unsalted butter, softened
  • 2 cups (400 g) granulated sugar
  • 4 large eggs, room temperature
  • 1 tbsp pure vanilla extract
  • 1 cup (240 ml) whole milk, room temperature
• For the Buttercream
  • 1 ½ cups (340 g) unsalted butter, softened
  • 6 cups (720 g) powdered sugar, sifted
  • ¼ cup (60 ml) whole milk
  • 2 tsp pure vanilla extract
  • Food coloring (pink, yellow, green, or as desired)

Instructions

1. Preheat oven to 350°F (175°C). Grease a 9x13-inch (23x33 cm) baking pan and line with parchment paper.

2. In a medium bowl, whisk together flour, baking powder, and salt.

3. In a large bowl, beat butter and sugar with an electric mixer until light and fluffy, about 3 minutes.

4. Add eggs one at a time, mixing well after each addition. Mix in vanilla extract.

5. Add flour mixture in three parts, alternating with milk, beginning and ending with flour. Mix until just combined; do not overmix.

6. Pour batter into prepared pan. Smooth the top with a spatula.

7. Bake for 28–32 minutes, or until a toothpick inserted in the center comes out clean.

8. Let cake cool in pan for 10 minutes, then turn out onto a wire rack to cool completely.

9. Prepare the buttercream: 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 for the base.

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 look.

13. Optionally, pipe a cross or add First Communion text with a small round tip.

Zusatztipps für die Zubereitung

Enhance the flavor of your cake by adding ½ tsp almond extract to the batter. Make the cake a day ahead to save time, storing it covered at room temperature to maintain freshness. Use gel food coloring for the buttercream to achieve vibrant, non-runny hues that hold their shape well during piping.

Varianten und Anpassungen

Feel free to experiment with different food coloring shades to customize the floral decorations to suit the color theme of your event. You can substitute whole milk with a dairy-free alternative if needed, keeping in mind it may slightly affect texture. For a more festive look, add optional piped crosses or personalized text using a small round piping tip.
