Ingredients

• 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

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 the Cake

Spread an even layer of buttercream over the cooled cake.

Step 9: Decorate

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 you begin—this helps create a smooth, evenly mixed batter. When alternating flour and milk, start and end with the flour mixture to prevent the batter from becoming too thin. Don't overmix once you add the flour, as this can lead to a dense cake. Allow the cake to cool completely before frosting to prevent the buttercream from melting. If the buttercream becomes too soft while decorating, refrigerate it for 10-15 minutes to firm up. For extra flavor, consider adding ½ tsp almond extract to the cake batter.

Varianten und Anpassungen

This versatile sheet cake can be customized to match any school's colors or theme. Use gel food coloring for more vibrant hues in your buttercream piping. For a dairy-free version, substitute non-dairy milk and dairy-free butter throughout the recipe. You can also transform this into a chocolate graduation cake by replacing ½ cup of flour with cocoa powder. Add a layer of fruit preserves or lemon curd between the cake and frosting for extra flavor. For a more elaborate design, use multiple piping tips to create borders, stars, or rosettes around the Class of 2026 message.

Serviervorschläge

Serve this graduation cake as the grand finale to your celebration meal, pairing it with fresh berries, ice cream, or a light fruit salad for contrast.
