How to Make Graduation Cake
Bake Cakes: Start by preparing your two yellow and two chocolate sheet cakes, each 9×13 inches. Also, bake one 5-inch diameter dome cake using the cotton candy batter. Once baked, let them cool completely on a wire rack.
Make Frosting: Whip up a batch of yellow American buttercream frosting. It should be smooth and easy to spread, perfect for sealing in those tasty cake layers.
Cap Preparation: After frosting the dome cake with a generous layer of buttercream, chill it in the refrigerator for about 30 minutes to set. Then, cover it with black fondant for a sleek graduation cap look.
Make Cap Decorations: Grab a square piece of cardboard and cover it in fondant to create the cap top. Attach a fondant circle on a folded ribbon for the tassel embellishment.
Assemble Cap: Secure the cardboard to the dome cake by using melted chocolate or royal icing. This will give your cap some stability and ensure it stays perched on top.
Create Diploma: Roll your Rice Krispie treats in fondant to shape the diploma. Add small circles of white fondant and a decorative ribbon to complete the look.
Assemble Main Cake: Begin layering and frosting the yellow and chocolate sheet cakes to make your main cake. Once stacked, place your decorated cap and diploma on top. Finish the cake by piping beautiful yellow roses and placing congratulatory letters around it for a personal touch.
Optional: Drizzle melted chocolate over the top for extra flair and sweetness.

Expert Tips for Graduation Cake
• Chill the Components: Make sure to chill the dome cake and frosting before assembly. This minimizes sticking and helps achieve a smoother finish on your graduation cake.
• Fondant Application: When covering the dome cake with fondant, dust your surface with powdered sugar to prevent sticking and help with easy handling.
• Stable Structure: Use dowels in the cake layers if your graduation cake becomes too tall. This will provide additional support for the cap and help avoid any accidental collapses.
• Piping Techniques: Practice piping roses on parchment paper before adding them to your cake. This allows for beautiful, uniform flowers when decorating with buttercream.
• Customize Your Cake: Feel free to modify colors and decorations to personalize your graduation cake for the graduate’s school colors or theme. Let your creativity shine!
How to Store and Freeze Graduation Cake
Room Temperature: Store the graduation cake in a cool place, covered loosely with plastic wrap, for up to 2 days to maintain its freshness.
Fridge: If you have leftovers, refrigerate the cake in an airtight container for up to 5 days. This helps preserve the moistness of the cake layers and the frosting.
Freezer: For longer storage, wrap the cake tightly in plastic wrap and then in aluminum foil. It can be frozen for up to 3 months. When ready to enjoy, thaw in the fridge overnight.
Reheating: While it’s best served cold or at room temperature, you can slightly warm individual slices in the microwave for about 10-15 seconds for a cozy treat, enhancing the experience of your delicious graduation cake.
