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 and preheat

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 ingredients

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 buttercream

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

To ensure your graduation cake turns out perfectly, make sure all your ingredients are at room temperature before starting—this helps create a smooth, evenly mixed batter. When alternating the flour mixture and milk, begin and end with the dry ingredients to prevent overmixing and ensure a tender crumb. For the buttercream, sift your powdered sugar to avoid lumps, and beat the frosting for the full 3–5 minutes to achieve that light, fluffy texture. If you want to add extra flavor dimension, consider adding ½ teaspoon of almond extract to the cake batter. Allow the cake to cool completely before frosting to prevent the buttercream from melting and sliding off.

Varianten und Anpassungen

This versatile recipe can be adapted to suit different dietary needs and flavor preferences. For a dairy-free version, substitute non-dairy milk (such as almond or oat milk) for the whole milk and use dairy-free butter alternatives—just ensure all ingredients align with your dietary requirements. You can customize the cake with different flavor extracts like almond, lemon, or even a touch of coconut for variety. For color customization, use gel food coloring in your graduate's school colors for both the frosting base and the piped decorations. If you prefer a different frosting style, this cake also works beautifully with cream cheese frosting or a simple chocolate ganache. Add texture and visual interest with different piping tips, edible glitter, fondant decorations, or themed cake toppers.
