DIY Planet Cakes from Cakecrumbs. There aren’t full blown tutorials for these cakes but she explains how she made them - especially the outer layer. First seen at Handmade Charlotte here.

The red layer is orange Madeira sponge, the yellow is lemon Madeira sponge and the white cake was a vanilla buttercake.

In cake speak, this translates to a core made of mudcake, surrounded by almond butter cake, surrounded by a tinted vanilla Madeira sponge. There’s a crumb coat of vanilla buttercream underneath the fondant.
