Assuming you would like a step-by-step guide on how to make a helmet shaped cake:
1. Begin by baking two 9-inch round cakes. Once they are cooled, use a serrated knife to level off the tops of the cakes so they are flat.
2. Cut each cake in half horizontally so that you have four thin layers of cake. Place one layer on a serving plate or cake stand, and spread it with some chocolate frosting. Top with another layer of cake and repeat the process until all four layers are stacked.
3. Spread a thin layer of frosting around the sides and top of the cake to crumb coat it and seal in any loose crumbs. Place the cake in the fridge for about 30 minutes to let the frosting set up before proceeding.
4. Once the crumb coat has set, begin covering the cake with your chosen color of fondant or modeling chocolate. Start by smoothing it over the top of the cake, then work your way down the sides until everything is covered evenly. You can use a fondant smoother or your hands to help give it an even finish.
5 visor: To make the visor, roll out some black fondant or modeling chocolate onto a surface dusted with powdered sugar or cornstarch (this will prevent sticking). Cut out a shield shape using a sharp knife or cookie cutter, then attach it to the front ofthe helmet using some water or edible adhesive such as piping gel.) finalize details: Use whatever tools you have on hand to add any final details you want on your helmetcake! Some things you could do include adding rivets aroundthe edges with white icing, painting stripes or logos with food coloring diluted in vodka, airbrushing shading effects, etc.. Be creative and have fun!
