Whipped cream frosting, made from heavy whipping cream, is lighter than buttercream frosting, which mainly uses butter. Whipped cream frostings are good to use on cakes in warm weather when you want a dessert that is not too heavy. However, whipped cream frostings need to be refrigerated until you are ready to serve them because they tend to slide off cakes when it is too hot. To decorate a cake with whipping cream, first whip together whipped cream frosting.
Whip heavy whipping cream and icing sugar in a large mixing bowl with a balloon whisk. You may also use the whisk attachment on an electric mixer. Keep whisking until soft peaks form.
Add piping gel and vanilla to your mix, which will make the whipped cream easier to work with. Continue whisking till you have stiff peaks.
Place your cake on a serving plate. Cut strips of waxed paper to put underneath the edges of your cake. This will prevent the whipped cream frosting from dripping on the serving dish. Lift the cake up slightly to place the strips of waxed paper around the bottom of the cake's edges.
Place the cake on the serving dish on a lazy susan. This will allow for easy turning of the cake for decorating.
Scoop whipped cream out of your mixing bowl with a spatula or icing knife. Place about half of the whipped cream onto the top of the cake.
Spread the whipped cream over the top of the cake. Be sure to smooth only the frosting and not the crumb of the cake. It does not have to be perfect now since you will smooth the frosting at the end.
Scoop more frosting from your bowl and add it to the sides of your cake, while using your other hand to turn the lazy susan. Add more whipped cream to frost all the sides of your cake.
Smooth the top of the cake with the flat edge of your spatula or icing knife. Hold the knife or spatula on the side of the cake and turn the lazy susan to smooth the sides.
Whipped cream frosting may also be placed into a piping bag for decorating your cake. Be sure to refrigerate your cake just before serving and refrigerate any leftover whipping cream.
