  • 1 tablespoon vanilla extract
  • 2 ½ teaspoons baking powder
  • ½ teaspoon salt
• Buttercream Frosting
  • 2 cups (450 g) unsalted butter, softened

Instructions

1. Preheat the oven

Preheat the oven to 350°F (175°C). Grease and line a 12x18-inch sheet cake pan with parchment paper.

2. Cream butter and sugar

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

3. Add eggs and vanilla

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

4. Combine dry ingredients

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

5. Mix batter

Add flour mixture to the butter mixture in three additions, alternating with milk. Begin and end with the flour mixture. Mix until just combined.

6. Prepare for baking

Pour batter into the prepared pan and smooth the top.

7. Bake

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

8. Cool cake

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

9. Make frosting

Beat butter until creamy. Gradually add powdered sugar, vanilla, and milk, mixing until fluffy. Adjust consistency with more milk or sugar as needed.

10. Color buttercream

Divide buttercream into bowls for coloring. Tint portions pink, red, or yellow for roses, green for leaves, and leave some white for the main cake coating.

11. Frost cake

Frost the cooled cake with a smooth layer of white buttercream.

12. Pipe decorations

Using a piping bag fitted with a rose tip, pipe buttercream roses in desired colors. Pipe green leaves with a leaf tip.

13. Create diploma

Shape a small piece of fondant or white chocolate into a scroll, tie with a ribbon of colored fondant, and place on the cake.

14. Add accents

Add edible pearls and any additional accents as desired.

Zusatztipps für die Zubereitung

For a chocolate variant of this sheet cake, simply substitute ¾ cup (75 g) of the all-purpose flour with unsweetened cocoa powder. Ensure all ingredients are at room temperature for the best texture. Using gel food coloring helps achieve vibrant, non-watery colors essential for detailed buttercream decorations.

Varianten und Anpassungen

Decorate the cake using your graduate's school colors for a personalized effect. The edible diploma can be customized with initials or messages using colored fondant or edible markers. For dietary restrictions, explore using dairy-free butter and milk substitutes, though these may alter texture and flavor.
