  • Cake: 2 ½ cups (315 g) all-purpose flour, 2 ½ tsp baking powder, ½ tsp salt, 1 cup (226 g) unsalted butter (softened), 1 ¾ cups (350 g) granulated sugar, 4 large eggs (at room temperature), 1 tbsp vanilla extract, 1 cup (240 ml) whole milk (at room temperature)
  • Buttercream Frosting: 1 cup (226 g) unsalted butter (softened), 4 cups (480 g) powdered sugar (sifted), ¼ cup (60 ml) whole milk, 2 tsp vanilla extract, pinch of salt, food coloring (school colors, if desired)
  • Decoration: Additional food coloring (for piping Class of 2026), sprinkles or edible decorations (optional)

Instructions

Step 1: Prepare the Pan and Oven
Preheat oven to 350°F (175°C). Grease a 9x13-inch (23x33 cm) sheet pan and line with parchment paper.
Step 2: Mix Dry Ingredients
In a medium bowl, whisk together flour, baking powder, and salt.
Step 3: Cream Butter and Sugar
In a large bowl, beat the butter and sugar together until light and fluffy, about 3 minutes.
Step 4: Add Eggs and Vanilla
Add eggs one at a time, beating well after each addition. Mix in vanilla extract.
Step 5: Combine Wet and Dry
Gradually add the flour mixture in three parts, alternating with the milk, beginning and ending with flour. Mix until just combined.
Step 6: Bake the Cake
Pour batter into prepared pan and smooth the top. Bake for 30–35 minutes, or until a toothpick inserted into the center comes out clean. Cool completely in the pan on a wire rack.
Step 7: Make the Frosting
For the frosting: Beat butter until creamy. Gradually add powdered sugar, milk, vanilla, and salt. Beat for 3–5 minutes until fluffy. Tint portions with food coloring as desired.
Step 8: Frost and Decorate
Spread an even layer of buttercream over the cooled cake. Use colored buttercream in a piping bag fitted with a small round tip to pipe Class of 2026 on top. Add sprinkles or other decorations as desired.

Zusatztipps für die Zubereitung

For the best results, ensure all your ingredients are at room temperature before beginning, as this allows for better emulsification and a smoother batter. When creaming the butter and sugar, don't rush this step—the full 3 minutes creates the air pockets that give your cake its tender texture. If you want to add extra flavor depth, consider incorporating ½ tsp almond extract to the cake batter. When alternating the flour mixture with milk, begin and end with the flour to prevent the batter from becoming too wet, and mix only until just combined to avoid developing too much gluten, which can make the cake tough. Allow the cake to cool completely before frosting to prevent the buttercream from melting and sliding off.

Varianten und Anpassungen

This versatile cake can be adapted to suit various dietary needs and preferences. For a dairy-free version, substitute non-dairy milk and use plant-based butter alternatives, ensuring all ingredients align with dietary requirements. You can personalize the cake by using your graduate's school colors for both the frosting tint and the piping—simply divide the buttercream into portions and add food coloring as needed. If piping isn't your strong suit, consider using store-bought letter stencils and filling them in with colored frosting, or simply write the message with a toothpick and trace over it with frosting. For chocolate lovers, replace ½ cup of flour with cocoa powder for a chocolate variation.

Serviervorschläge

This graduation sheet cake shines as the centerpiece of any celebration dessert table. Serve it alongside fresh berries and whipped cream for guests who want a lighter accompaniment, or pair it with vanilla ice cream for an indulgent treat. For an elegant presentation, cut the cake into uniform squares and arrange them on a tiered serving platter. The cake can be stored covered at room temperature for up to 2 days, making it perfect for advance preparation, or refrigerated for up to 5 days if your party plans change. When serving, use a sharp knife wiped clean between cuts to maintain neat edges and showcase your beautiful piping work.
