Ingredients

• Cake
  • 3 cups (375 g) all-purpose flour
  • 2 ½ cups (500 g) granulated sugar
  • 1 cup (225 g) unsalted butter, softened
  • 1 cup (240 ml) whole milk, room temperature
  • 6 large eggs, room temperature
  • 1 tablespoon vanilla extract
  • 2 ½ teaspoons baking powder
  • ½ teaspoon salt
• Buttercream Frosting
  • 2 cups (450 g) unsalted butter, softened
  • 8 cups (1 kg) powdered sugar, sifted
  • ½ cup (120 ml) whole milk or heavy cream
  • 2 teaspoons vanilla extract
  • Food coloring (gel preferred), as needed for roses, leaves, and diploma
• Decorations
  • Edible gold or silver pearls (optional, for accents)
  • Fondant or white chocolate for diploma and ribbon (optional)

Instructions

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

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

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

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

5. 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. Pour batter into the prepared pan and smooth the top.

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

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

Buttercream & Decoration:

9. For the 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. 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 the cooled cake with a smooth layer of white buttercream.

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

13. For the 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 edible pearls and any additional accents as desired.

Tips for Success

For a chocolate twist, replace ¾ cup (75 g) of flour with unsweetened cocoa powder to create a rich chocolate version of this classic sheet cake. Using gel food coloring ensures vibrant buttercream hues without watering down the frosting, making it easier to pipe and maintain sharp colors. Always start with softened butter and room temperature eggs for the best cake texture.

Variations and Adaptations

Customize the cake to your graduate's school colors by adjusting the buttercream color palette accordingly. For a vegan adaptation, consider plant-based butter and egg substitutes, though adjustments to texture and baking time might be necessary. Use fondant decorations sparingly for an elegant finish, or add edible glitter for extra sparkle.

Serving Suggestions

This cake pairs beautifully with a glass of milk, coffee, or tea and is perfect for slicing and serving at large graduation parties. Garnish each slice with a small buttercream rose or pearl for extra flair. Leftovers can be refrigerated and enjoyed over the next several days, allowing flavors to meld even further.
