Remove your ice cream cake from the freezer and store it, uncovered, for around 30 minutes (at room temperature) before you would like to serve it. Your cake should be served when it is just starting to melt, to appreciate the full flavour of the layers. Try not to eat the cake straight out of the freezer! 10 minutes before serving, take the horn and ears out of the freezer, add them to the cake in the pre-assigned spaces, using the pre-made piping bag of ganache to stick them to your cake. Slice as you would an ordinary cake using a dry knife. It’s best not to use a wet knife as this may cause ice to form. If it’s a little difficult to slice through, run your knife under a hot tap and dry thoroughly before slicing.
If you wish to add candles it’s easier to use candle holders. Sparklers are fun but may cause the top of the cake to melt slightly.
