To make the cone you’ll need 2 of the 6-inch cakes. To make the ice cream on top you’ll need one of the 6” cakes and the sphere cake.Let’s begin with the Cone.
Add a little blob of peppermint frosting onto an 8”cake board. Place on 6-inch cake on top and firmly press down to help it stick to the cake board. Pipe a ring of frosting on top of the cake and fill with more frosting. Place the next layer of cake on top.
To crumb coat the cake, add frosting on top of the cake and on the sides and use a small offset spatula to smoothen out. It doesn’t need to look perfect but get it as smooth as you can. Place 3 bubble tea straws in the cake making sure to cut off any excess straw that may be sticking out. Chill for 1 hour.
Use a sharp knife to cut out a shallow 5” circle on top of the cake You’re going to use that as a guide to cut out an angle shape from the top of the cake to the bottom of the cake to five us a cone shape. Once you’ve gone around the cake and cut away the excess cake. Crumb coat the cake again. Chill for 1 hour.
Add a blob of waffle frosting on top of the chilled cake and place a cake board on top. Place your hand under the bottom cake board and another hand on top of the top cake board and flip the cake around so the narrow side of the cone cake is now on the bottom. Carefully take the top cake board off the top of the cake.
To add the final layer of frosting add the waffle frosting on top of the chilled cake and use a small offset spatula to smoothen out. Place a 6” cake board on top and then add more waffle frosting on top. Smoothen that out again. What we’ve just done is add a support structure in the cone cake so that when we place the ice cream cake on top, it won’t cause the cone cake to collapse.
Add waffle frosting around the sides of the cake. Use a bench scraper or cake scraper to smoothen out the frosting on the sides of the cake and on top. You’ll need to hold the bench scraper on an angle when going around the sides of the cake. Set aside to chill for another hour.
To finish off the waffle cake fit the end of a piping bag with a small round tip. Use a ruler to indent lines into the cake, criss crossing each other. You’ll use those as guides to pipe the final waffle details.
Stick the eyes and mouth onto the waffle cake and set aside to chill while you move onto the ice cream cake.
