Ingredients

• For the Sheet Cake: 3 cups (375 g) all-purpose flour, 2 ½ tsp baking powder, ½ tsp baking soda, ½ tsp salt, 1 cup (225 g) unsalted butter at room temperature, 2 cups (400 g) granulated sugar, 4 large eggs at room temperature, 1 tbsp vanilla extract, 1 ¼ cups (300 ml) whole milk at room temperature
• For the Buttercream: 1 ½ cups (340 g) unsalted butter at room temperature, 6 cups (720 g) powdered sugar sifted, ¼ cup (60 ml) whole milk, 2 tsp vanilla extract, food coloring in gel form preferred with assorted colors for roses and leaves

Instructions

Step 1: Prepare the Pan and Oven

Preheat your oven to 350°F (175°C). Grease a 12x18-inch sheet cake pan thoroughly and line it with parchment paper to ensure easy removal after baking.

Step 2: Mix the Dry Ingredients

In a medium bowl, whisk together the flour, baking powder, baking soda, and salt until well combined. Set aside.

Step 3: Cream Butter and Sugar

In a large bowl using an electric mixer, cream the butter and sugar together until light and fluffy, about 3-4 minutes. This step incorporates air for a lighter cake texture.

Step 4: Add Eggs and Vanilla

Add the eggs one at a time, beating well after each addition to ensure full incorporation. Mix in the vanilla extract.

Step 5: Combine Wet and Dry

Alternately add the flour mixture and milk to the creamed mixture, beginning and ending with the flour. Mix just until combined to avoid overworking the batter.

Step 6: Bake the Cake

Pour the batter into the prepared pan and smooth the top with an offset spatula. Bake for 30–35 minutes, or until a toothpick inserted in the center comes out clean.

Step 7: Cool Completely

Allow the cake to cool completely in the pan on a wire rack before frosting. This prevents the buttercream from melting.

Step 8: Make the Buttercream

Beat the butter until creamy. Gradually add the powdered sugar, then the milk and vanilla. Beat until smooth and fluffy, about 5 minutes.

Step 9: Color the Buttercream

Divide the buttercream into separate bowls. Tint portions with food coloring for roses in colors like red, pink, or yellow, and green for leaves. Leave some white for the base coat.

Step 10: Apply Base Coat

Spread a thin layer of white buttercream over the cooled cake using an offset spatula to create a smooth base for your decorations.

Step 11: Pipe Roses and Leaves

Fit piping bags with desired tips such as a petal tip for roses and a leaf tip for leaves. Pipe roses and leaves across the cake, focusing on corners or creating a border design.

Step 12: Add Personal Message

Using a small round tip, pipe a congratulations message or personalized graduation greeting on the cake to complete your masterpiece.

Zusatztipps für die Zubereitung

For the best results, ensure all your ingredients are at room temperature before beginning. This allows for better emulsification and a smoother batter. When mixing the batter, alternate between the flour mixture and milk, starting and ending with flour to prevent curdling. Use gel food coloring rather than liquid varieties, as they provide more vibrant colors without thinning your buttercream. Practice piping roses on parchment paper before decorating the cake if you're new to this technique. You can even freeze practice roses on parchment and transfer them to the cake once firm.

Varianten und Anpassungen

Transform this vanilla sheet cake into a chocolate celebration by substituting ¾ cup of the flour with ¾ cup unsweetened cocoa powder. For a marble effect, divide the batter and add cocoa to half, then swirl together in the pan. You can also flavor the buttercream with almond extract, lemon zest, or even espresso powder for different taste profiles. Match your graduate's school colors by tinting the buttercream accordingly, or create an ombre effect with roses in graduating shades. For a lighter option, reduce the sugar in the buttercream by one cup and add a pinch of salt to balance the sweetness.

Serviervorschläge

This stunning graduation cake is best served at room temperature to showcase its soft, moist texture and smooth buttercream. Pair slices with sparkling lemonade for a refreshing afternoon celebration, or serve with champagne or sparkling cider for evening festivities. For a complete dessert spread, accompany with fresh berries, a fruit salad, or small scoops of vanilla ice cream. The cake stores well covered at room temperature for up to 2 days, or refrigerated for up to 5 days. If refrigerated, allow slices to come to room temperature for 30 minutes before serving for the best flavor and texture.
