Ingredients

Scale
  • 2 ½ cups (312g) all-purpose flour
  • 2 ½ tsp baking powder
  • ½ tsp baking soda
  • ½ tsp salt
  • 1 cup (226g) unsalted butter, softened
  • 1 ¾ cups (350g) granulated sugar
  • 4 large eggs, room temperature
  • 1 tbsp vanilla extract
  • 1 cup (240ml) whole milk (or almond milk for dairy-free)
  • 1 cup (226g) unsalted butter, softened (for frosting)
  • 4 cups (480g) powdered sugar, sifted
  • 23 tbsp whole milk or cream (for frosting)
  • 1 tsp vanilla extract (for frosting)
  • Gel food coloring in school colors
  • Edible gold leaf sheets or gold dust
  • Gold edible spray (optional)
  • Sprinkles or piped accents in school colors (optional)

Instructions

  1. Preheat oven to 350°F (175°C) and grease a 9×13 inch sheet cake pan. Line with parchment paper if desired.
  2. Sift together flour, baking powder, baking soda, and salt in a medium bowl. Set aside.
  3. In a large bowl, beat softened butter and sugar until light and fluffy, about 3-5 minutes.
  4. Add eggs one at a time, beating well after each addition. Stir in vanilla extract.
  5. Add dry ingredients in three parts, alternating with milk, starting and ending with dry ingredients. Mix just until combined.
  6. Pour batter into prepared pan and smooth the top. Tap pan gently to release air bubbles.
  7. Bake for 35-40 minutes or until a toothpick inserted in the center comes out clean. Cool completely in pan on a wire rack (about 1 hour).
  8. For frosting, beat softened butter until creamy. Gradually add powdered sugar, beating well between additions.
  9. Add milk and vanilla extract to frosting, adjusting milk to reach spreadable consistency.
  10. Divide frosting into bowls and add gel food coloring to create school colors. Mix until smooth.
  11. Apply a thin crumb coat to the cooled cake and chill for 15 minutes.
  12. Apply a thicker final layer of frosting, smoothing with a bench scraper or offset spatula.
  13. Carefully apply edible gold leaf with a dry brush or fingers. Use gold edible spray and pipe accents or sprinkles in school colors if desired.

Notes

Use room temperature ingredients for best results. Do not overmix batter to keep cake tender. Chill cake after crumb coat for smooth frosting finish. Handle edible gold leaf with dry tools to avoid tearing. Frosting can be refrigerated briefly if too soft during decorating.
