How to Make Elegant Graduation Cake with Fondant Cap Topper
Bake the Cakes: Preheat your oven to 350°F (175°C). Prepare your cake pans with baking spray and parchment paper. Divide batter between the yellow, chocolate, and cotton candy cake recipes, ensuring even distribution in each pan. Bake for about 40 minutes or until a toothpick comes out clean from the center. Let cakes cool completely.
Prepare the Buttercream Frosting: In a large mixing bowl, combine 10 cups of softened American buttercream frosting. Add drops of yellow gel food coloring and mix until you reach your desired shade. Remember, you want it bright and vibrant!
Stack and Frost the Cakes: Level the tops of each cake layer if needed. Start stacking your cakes by placing a yellow cake layer on a cake board. Spread an even layer of frosting on top before adding the next cake layer. Alternate between yellow, chocolate, and cotton candy layers until all are stacked. Frost the sides and top with a generous layer of the yellow buttercream. Smooth the frosting for a polished look.
Make the Rice Krispie Treats: Follow the instructions on your Rice Krispie treats package or melt 3 tablespoons of butter in a large saucepan. Add 1 package of mini marshmallows, and stir until melted. Remove from heat and mix in 6 cups of Rice Krispies. Once combined, mold the mixture into a small cap shape and leave it to cool.
Create the Fondant Cap Topper: Once the Rice Krispie treat cap has cooled, roll out your black and white marshmallow fondant. Shape the black fondant into the top of the cap and the white into a circular base. Place the black fondant on top of the Rice Krispie cap, and adjust until it resembles a graduation cap. Don’t forget to cut a small piece of fondant for the tassel!
Assemble the Decorations: Place the fondant cap on top of your cake and position a rolled-up piece of white fondant to look like a diploma next to it. You can secure it with a tiny ribbon made from leftover white fondant.
Serve and Celebrate: Slice into your creation and share it with family and friends as you celebrate this major academic achievement! Each slice reveals the beautiful layers within, ensuring everyone gets a taste of the delicious flavors.
Storing & Reheating
Store any leftover cake in an airtight container at room temperature for up to 2 days. If you need to keep it longer, refrigerate for a week. To freeze, wrap slices tightly in plastic wrap and store them in a freezer-safe bag for up to 3 months. When you’re ready to enjoy, thaw in the fridge overnight before serving. The texture might change slightly, so a light re-frosting with buttercream can refresh its appearance.
Chef’s Helpful Tips
- Keep all your ingredients at room temperature before starting; this helps achieve a smoother batter.
- Level your cake layers after cooling to ensure a neat stack.
- Use a bench scraper to smooth the frosting for a polished final look.
- Want a flavor boost? Add vanilla or almond extract to the batter and frosting for a new twist.
- If you have extra frosting, it can be used as a filling for cookies or as a dip for fruit!
