Ingredients

Sifting ensures a tender crumb each time, and I learned to measure carefully for consistency.
Essential for that gentle rise; fresh baking powder gives the cake lightness that’s unmistakable.
Soft butter blends seamlessly for a smooth batter and creamy frosting, so room temperature is key.
Beating it with butter until fluffy creates the dreamy texture and golden edges everyone loves.
Bringing eggs to room temperature avoids curdling and helps the cake mix properly.
It transforms the base into something nostalgic and inviting.
Alternating milk with dry ingredients yields a soft, moist cake.
Sifting prevents lumps in the frosting, making it smooth and glossy.
Gel colors are vivid without changing the texture of your buttercream.
Reserved for that dose of festive sparkle—the cake’s crowning glory.

Ingredient List

Sheet Cake

01 2 1/2 cups all-purpose flour

02 2 1/2 teaspoons baking powder

03 1/2 teaspoon salt

04 1 cup unsalted butter, room temperature

05 2 cups granulated sugar

06 4 large eggs, room temperature

07 1 tablespoon vanilla extract

08 1 cup whole milk, room temperature

Buttercream Frosting

01 1 1/2 cups unsalted butter, room temperature

02 6 cups powdered sugar, sifted

03 2 teaspoons vanilla extract

04 4 to 6 tablespoons milk or heavy cream

05 Food coloring (school colors and black for piping, as desired)

Decoration

01 Sprinkles, edible glitter, or colored sugar (optional)

Directions

Step 01

Prepare Baking Equipment: Preheat oven to 350°F. Grease and line a 13x18-inch sheet pan with parchment paper.

Step 02

Combine Dry Ingredients: Whisk together all-purpose flour, baking powder, and salt in a medium bowl.

Step 03

Cream Butter and Sugar: Beat unsalted butter and granulated sugar in a large bowl with an electric mixer until light and fluffy, about 3–4 minutes.

Step 04

Add Eggs and Vanilla: Incorporate eggs one at a time, beating well after each addition; mix in vanilla extract.

Step 05

Combine Wet and Dry Ingredients: Add dry mixture to wet ingredients in three parts, alternating with whole milk. Begin and end with dry mixture. Mix gently until just combined.

Step 06

Bake Cake: Pour batter into prepared pan and smooth the surface. Bake for 30–35 minutes or until a toothpick inserted in the center emerges clean.

Step 07

Cool Cake Completely: Allow cake to cool fully in the pan on a wire rack before frosting.

Step 08

Prepare Buttercream Frosting: Beat butter on medium speed until creamy. Gradually add sifted powdered sugar, beating thoroughly. Incorporate vanilla extract and enough milk or cream to achieve a smooth, spreadable consistency.

Step 09

Color and Divide Frosting: Divide buttercream as needed; tint portions for the base layer, borders, and piping decorations using desired food colorings.

Step 10

Frost and Decorate Cake: Spread an even layer of colored frosting atop the cooled cake. Pipe decorative borders and 'Class of 2026' text using piping bags fitted with writing and star tips. Garnish with sprinkles, edible glitter, or colored sugar if desired.

Step 11

Set Frosting: Refrigerate the finished cake for 30 minutes prior to serving to ensure the buttercream sets properly.
