How to Make Elegant Graduation Cake with Fondant Cap Topper
Bake the cake layers: Preheat your oven to 350°F (175°C) and prepare your pans with non-stick spray. Bake the yellow and chocolate cake layers for about 20-25 minutes, or until a toothpick inserted comes out clean. For the cotton candy cake, keep an eye on it after 30 minutes for doneness.
Cool and level the cakes: Once baked, let the cakes cool in their pans for about 10-15 minutes, then transfer them to wire racks to cool completely. Level the tops if needed to create even layers.
Prepare the frosting: While your cakes cool, make your buttercream frosting, tinting it yellow with gel food coloring for that grad cap vibe. Whip together until fluffy, adding a bit of milk if it’s too stiff.
Assemble the cake: Start with a yellow layer on a cake board or platter. Spread a generous layer of frosting on top, then add a chocolate layer. Continue the alternating layers: yellow, chocolate, yellow, and finally your cotton candy layer on top.
Crumb coat: Spread a thin layer of frosting over the entire cake to seal in crumbs. Chill in the fridge for about 30 minutes.
Frost the cake: With the crumb coat set, frost the entire cake generously with the yellow frosting. Smooth it out for a polished finish.
Make the fondant cap and diploma: Roll out the black fondant to form a square for the cap, and shape the white fondant into a scroll for the diploma. Use the Rice Krispie treats to form the top of the cap, securing it on top with a little frosting.
Decorate: Use additional fondant to add details, like a tassel for the cap. The diploma can be placed on the cake or next to it on the serving table.
Serve and enjoy: Slice your stunning cake and serve it to your guests. Be prepared for all the praise and happy cheers!
Storing & Reheating
Store any leftover cake at room temperature for up to 2 days, covered in an airtight container to maintain its moisture. If you’d like to keep it longer, refrigerate for about a week or freeze it for up to 3 months. Wrap slices in plastic wrap and foil before freezing. To enjoy later, simply thaw at room temperature, but be aware that the texture may change slightly after freezing. A quick zap in the microwave for about 10 seconds can bring back some of that fresh cake softness!
Chef’s Helpful Tips
- Avoid overmixing: When combining your cake ingredients, mix until just combined to ensure a tender crumb.
- Ingredient temperatures matter: Use eggs at room temperature for better incorporation into your batter.
- Level up your layers: If your cakes domed during baking, carefully trim the tops for even stacking.
- Frosting flavors: Feel free to flavor your buttercream with vanilla or almond extract for an extra flavor punch.
- Make-ahead: You can bake your cake layers and prepare buttercream a day in advance; just keep everything covered in the fridge!

Ingredients
- 2 Yellow sheet cakes
- 2 Chocolate sheet cakes
- 1 Cotton candy cake
- 10 cups American buttercream frosting (Tinted yellow with gel food coloring)
- 4 cups Marshmallow fondant (2 cups of black and 2 cups of white)
- 1 batch Rice krispie treats (Can also use store-bought)
Instructions
- Bake 2 yellow sheet cakes (Dimensions: 9×13), 2 chocolate sheet cakes (Dimensions: 9×13) and 1 cotton candy dome cake (5 inch diameter). Use leftover cotton candy cake batter to make cupcakes if desired.
- Allow cakes to cool completely.
- Prepare yellow buttercream frosting while cakes cool.
- For the cap cake, place the dome cake on a cake board of the same size and frost smoothly with buttercream. Chill for 20 minutes.
- Roll out black fondant and cover the chilled dome cake. Smooth with a fondant smoother. Trim excess fondant with a pizza cutter and insert a bubble tea straw into the center.
- Cut a square piece of cardboard for the cap top. Color the edges with a black edible marker and spread a thin layer of icing before covering with black fondant. Trim excess fondant as necessary.
- Use a small circle cutter for a piece to top the cap. Brush corn syrup on the cardboard, fold a ribbon, and press the circle on top to adhere.
- Secure the cap to the dome cake with melted chocolate or royal icing and steam to remove powdered sugar residue.
- For the diploma, shape rice krispie treats into a cylinder and spread buttercream on the sides.
- Wrap the treat log in white fondant and cut excess. Adhere white fondant circles on the ends with buttercream, wrapping a red ribbon around it.
- Assemble by placing the 2 chocolate sheet cakes side by side on a large cake board, adding icing on top, and layering the yellow sheet cakes over the icing.
- Smooth the top and sides of the layered cakes with icing, then use a piping bag with yellow icing to create roses on the sides and top.
- Determine where to place the diploma and cap, adding supports as needed, and position them on the cake.
- Cut out letters for 'Congratulations Class of 2024' using cookie cutters, and attach them to the cake board with icing.
Notes
For a more vibrant color, you can add more gel food coloring to the buttercream frosting.
Make sure to chill the fondant before handling it for easier shaping.
Feel free to customize the diploma design with different colors or messages.
