Bill’s Vanilla Whipped Buttercream


I’ve been fan girling over Bill Grainger for years and this has to be my favourite Bill recipe – it makes perfect buttercream every single time! I first gave it a go when I made Bill’s Cake for a Crowd and I’ve been loving on this recipe ever since.

This whipped buttercream is super easy to make but unless you have arms like Popeye, you’ll need a stand mixer or a Thermomix to help things along. This buttercream has been the star of the show on all the birthday cakes we’ve made, including this Moana Cake, this Lion Guard Cake and of course, the AWW Koala Cake.It goes great in a cake sandwich and works equally well for decorating the top and sides. Everyone tells me how much they love the buttercream and I have to confess it is beater-lickingly good.
