- 4 Cups Marshmallow Fondant (2 Cups of Black and 2 Cups of White): This fondant gives the cake its elegant topper and cute diploma look; you can make it at home or buy pre-made.

How to Make Elegant Graduation Cake with Fondant Cap Topper
- Bake the Cakes: Preheat your oven to 350°F (175°C). Grease and flour your sheet pans. Divide the batter evenly between two yellow and two chocolate sheet pans, then bake for 25-30 minutes or until a toothpick comes out clean. Allow them to cool completely.
- Prepare the Frosting: While the cakes cool, prepare your American buttercream frosting. Beat 10 cups of butter, sugar, and vanilla together until creamy. Add gel food coloring to achieve a vibrant yellow shade, making your cake festive.
- Layer the Cakes: Once the cakes are cool, level them if needed. Start by placing a yellow cake layer on your serving platter, thickly spreading a layer of buttercream on top. Layer a chocolate cake next, continuing to alternate until all cakes are stacked, finishing with a yellow layer on top.
- Crumb Coat: Apply a thin, even coat of buttercream frosting over the entire cake to trap any crumbs. Chill the cake for about 30 minutes until the crumb coat sets.
- Frost the Cake: After chilling, generously frost the cake in yellow buttercream, smoothing the surface with an offset spatula for a polished look.
- Create the Fondant Cap: While the cake is chilling, prepare the Rice Krispie treats according to the package or recipe. Once cooled, shape a small bowl to form the cap. Cover it with black fondant, creating a smooth finish and a small brim.
- Decorate with Fondant: Roll out white fondant to create a diploma shape. Tie it with a thin strip of black fondant to resemble a real diploma, and set it aside.
- Final Assembly: Carefully place the marshmallow fondant cap on top of the cake. Position the diploma on the side or near the base for a charming effect.
- Presentation: Finish with extra buttercream decorative swirls around the base or add personalized touches, such as a name tag, using leftover fondant.
Storing & Reheating
Store leftover cake in an airtight container at room temperature for up to two days. For longer storage, place the cake in the refrigerator, where it can last up to a week. If you need to freeze it, wrap the cake tightly in plastic wrap and then in foil—this way, it stays fresh for up to three months. When you’re ready to enjoy, simply thaw it in the refrigerator overnight. The texture might change slightly after freezing, but refreshing it with a little extra frosting can restore its creamy goodness.
Chef’s Helpful Tips
- Ensure the eggs are at room temperature for a smoother batter; you’ll get a fluffier cake that rises beautifully.
- Sifting the flour helps remove any lumps and gives your cake a light texture.
- Take your time frosting the cake. A well-frosted cake looks polished and professional.
- If using store-bought fondant, knead it slightly before rolling it out to make it easier to work with and more pliable.
- Don’t rush the chilling process after the crumb coat—this step is crucial to achieving a clean final layer of frosting.
