Gluten-free chocolate mud cake

When we first opened our café in Hampstead, baking cakes in our minuscule kitchen was impossible, so we found a wonderful local pastry chef, Alison, to bake them for us. When she moved on to open her own place, we begged her to share a few of her recipes with us in case there was a riot, and luckily she agreed. We are proud to present her wonderful ‘mud’ cake, which has a soft, mousse-like centre.
