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 ingredients are at room temperature before beginning—this helps create a smooth, evenly mixed batter. When alternating flour and milk, mix only until just combined to avoid overworking the batter, which can lead to a tough cake. Allow the cake to cool completely before frosting to prevent the buttercream from melting. For easier piping, practice your lettering on parchment paper first, and use a toothpick to lightly sketch the design on the frosted cake before piping.

Varianten und Anpassungen

Customize this cake to match your graduate's preferences and dietary needs. Add ½ tsp almond extract to the cake batter for extra flavor depth. Use school colors for piping and decorations to personalize the cake for your specific graduation. For a dairy-free version, substitute non-dairy milk and ensure all other ingredients support dietary needs. You can also experiment with different frosting flavors by adding citrus zest, espresso powder, or different extracts to the buttercream.
