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 and add the meringue topper. 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! 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.
