How to Make Elegant Graduation Cake with Fondant Cap Topper
Prepare the Cakes: Preheat your oven to 350°F (175°C). Grease and flour your sheet cake pans. Bake the yellow and chocolate cakes according to the package instructions or your preferred recipe, usually about 30 minutes, until a toothpick comes out clean. Once baked, allow them to cool completely on wire racks.
Make the Buttercream Frosting: In a large mixing bowl, beat 1 cup of softened butter until creamy. Gradually add in about 10 cups of powdered sugar, alternating with a splash of milk until you achieve a smooth consistency. Use gel food coloring to tint the frosting a vibrant yellow.
Assemble the Cake: Place one layer of yellow cake on a serving platter. Spread a generous layer of buttercream frosting on top, then add a layer of chocolate cake. Repeat the process, alternating flavors until all layers are stacked. Finish with a smooth layer of frosting over the entire cake.
Prepare the Fondant Decorations: If making fondant yourself, melt the marshmallows with a splash of water and mix in powdered sugar until a dough forms. Divide the fondant into two parts: color one half with black gel food coloring and leave the other white. Roll out the black fondant and cut out a square for the cap and a thin strip for the board.
Create the Diploma: Shape the Rice Krispie treats into a small log and wrap in the white fondant. Tie it with a piece of the black fondant to secure it, creating a realistic diploma.
Finish the Cake: Gently place the fondant cap on top of the finished cake and rest the diploma against it. Add simple decorations like stars, if desired, with leftover fondant.
Chill and Serve: Refrigerate for about 30 minutes to set the decorations, then serve your stunning creation!
Storing & Reheating
To keep your Elegant Graduation Cake fresh, store leftovers in an airtight container at room temperature for up to 2 days or in the refrigerator for a week. If you wish to store it longer, freeze individual slices wrapped tightly in plastic wrap for up to 3 months. When ready to enjoy, simply let it thaw at room temperature for about 30 minutes. The texture of the frosting remains delightful, but you might notice the fondant becomes a bit softer.
Chef’s Helpful Tips
- Keep your ingredients at room temperature, especially butter and eggs, for better mixing and texture.
- To avoid crumbs mixing into your frosting, apply a thin crumb coat of frosting first and chill the cake for 15 minutes before adding the final layer.
- If the fondant seems too sticky, dust your work surface lightly with powdered sugar as you roll it out.
- Make the layers of cake a day in advance to save time; just wrap them tightly to keep them moist before frosting.
This Elegant Graduation Cake with Fondant Cap Topper is not just a dessert; it’s a statement of celebration and achievement. With its crowd-pleasing flavors and striking design, it’s bound to be a hit at any graduation party. Get creative with the decorations, perhaps adding photos or themed elements that reflect the graduate’s journey. Remember, this recipe is all about making those cherished moments sweeter.

Recipe FAQs
Can I use different flavors for the cake?
Absolutely! Feel free to experiment with any flavorful combinations you like. Vanilla, red velvet, or even carrot cake could make fantastic alternatives to suit the graduate’s taste preferences.
How long will the fondant decorations last?
Fondant decorations can last up to several weeks if stored in a cool, dry place. However, once applied to the cake, it’s best to consume it within a week for optimal freshness.
Can I prepare the cake ahead of time?
Certainly! You can bake the cakes and prepare the frosting up to a few days in advance, storing them separately in the refrigerator. Assemble and decorate the cake the day before the celebration for best results.
Is there a way to make this cake gluten-free?
Yes! Simply replace all-purpose flour with a gluten-free cake mix and ensure that any additional ingredients, like the Rice Krispies or frosting, are gluten-free to keep the cake suitable for those with dietary restrictions.

Description
This Elegant Graduation Cake with Fondant Cap Topper is a delightful blend of flavors, featuring yellow, chocolate, and cotton candy cakes adorned with silky buttercream and charming decorations, making it perfect for graduation celebrations.
Ingredients
- 2 yellow sheet cake
- 2 chocolate sheet cake
- 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 (9×13 dimensions), 2 chocolate sheet cakes (9×13 dimensions), and 1 cotton candy dome cake (5 inch diameter). Reserve any leftover cotton candy batter for cupcakes.
- Allow cakes to cool completely.
- Prepare the yellow buttercream frosting while the cakes cool.
- To create the cap cake, place the dome cake on a cake board the same size. Frost it smoothly with buttercream and chill for 20 minutes.
- Roll out black fondant and drape it over the chilled dome cake, smoothing it out. Remove excess fondant with a pizza cutter. Insert a bubble tea straw in the center and set aside.
- For the cap's top, cut a square of cardboard and color the edges with a black edible marker. Apply icing and layer black fondant on top, removing excess with a cutter.
- Cut a small circular piece from fondant, brush corn syrup on the cardboard, fold a ribbon, and press the circle piece on top to secure everything.
- Attach the cardboard piece to the dome cake with melted chocolate or royal icing, then steam to eliminate powdered sugar residue.
- To make the edible diploma, roll rice krispie treats into a cylinder and cover the sides with buttercream.
- Wrap the rice krispie log in white fondant and trim the excess. Use a cookie cutter to make 2 circles of white fondant and attach them with buttercream icing. Finish by wrapping a red ribbon around the diploma.
- Assemble the cake by placing the 2 chocolate sheet cakes side by side on a large board, then place the yellow sheet cakes on top, spreading icing in between.
- Use a piping bag with yellow icing and large star tip (Wilton tip 1M) to pipe roses on the sides and top of the cake.
- Decide where to place the diploma and cap on the cake, reinforcing with dowels or bubble tea straws. Position the decorations accordingly.
- Cut out letters for 'Congratulations Class of 2024' with cookie cutters and secure them on the board with buttercream.
Notes
Make sure to cool cakes completely before frosting for the best results.
Feel free to customize cake colors according to school themes or personal preferences.
Using a piping bag helps achieve a professional-looking finish for the roses.
