Ingredients

• 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
• 1 ½ cups (340 g) unsalted butter, softened (for buttercream)
• 6 cups (720 g) powdered sugar, sifted
• ¼ cup (60 ml) whole milk (for buttercream)
• 2 tsp pure vanilla extract (for buttercream)
• Food coloring (pink, yellow, green, or as desired)

Instructions

Step 1

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

Step 2

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

Step 3

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

Step 4

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

Step 5

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

Step 6

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

Step 7

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

Step 8

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

Step 9

Prepare the buttercream: Beat butter until creamy. Gradually add powdered sugar, alternating with milk, beating until smooth and fluffy. Mix in vanilla.

Step 10

Divide buttercream into bowls and tint portions with food coloring for flowers and leaves.

Step 11

Spread a generous layer of plain buttercream over cooled cake for the base.

Step 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.

Step 13

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

Zusatztipps für die Zubereitung

For the best results, ensure all ingredients—especially butter, eggs, and milk—are at room temperature before mixing. This helps create a smooth, evenly textured batter. Use gel food coloring rather than liquid for more vibrant, non-runny buttercream hues. If you're new to piping, practice your flower designs on parchment paper first. The cake can be baked a day ahead and stored covered at room temperature, then frosted and decorated on the day of your celebration.

Varianten und Anpassungen

Add ½ teaspoon almond extract to the cake batter for extra depth of flavor that complements the vanilla beautifully. For a chocolate lover, substitute ½ cup of the flour with cocoa powder for a marble effect. You can also flavor the buttercream with lemon zest or a splash of rosewater for a more sophisticated profile. If dietary restrictions apply, substitute whole milk with almond or oat milk, though the texture may vary slightly.

Serviervorschläge

Serve slices of this elegant cake alongside a light Moscato for adults or fresh lemonade for children. The buttercream flowers pair wonderfully with fresh berries or a light fruit compote on the side. For an extra-special presentation, place each slice on a white dessert plate with a small sprig of fresh mint. This cake is ideal for serving at room temperature, allowing the buttercream to remain soft and the vanilla flavor to shine through.
