While I never did pick up her cake decorating chops, I often find myself reaching for the angled icing spatulas she handed down. While they’re made to scrape icing, I find that they come in hand ...

But do give the icing a stir with a spatula every now and again. Line the bottom of your springform cake tin (you will need a good, leakproof one as this is a very wet batter) with baking parchment.
