Courgette & Lime BOO Cake

We’re doing cutesy Halloween around here!

This is a courgette and lime take on a madeira sponge; so a sponge that’s got a bit of weight to it. The buttercream is a russian buttercream which I’ve added a blackberry compote to for colour. If you want the cake to be really zesty, add in the zest from 3 or 4 limes rather than 2.
