Meanwhile, whisk the sugar, eggs and a pinch of salt together in a large bowl until pale and foamy – it should look like a frothy milkshake. This will take 2-3 mins with an electric whisk, or about 5-8 mins with a balloon whisk. Pour in the butter and chocolate mixture along with the almonds, then fold everything together until there are no streaks of chocolate. Tip the mixture into the tin, scatter over the rest of the chocolate, and bake for 25 mins, until cooked with a slight wobble in the middle.

Heat the oven to 190C/170C fan/gas 5 and line a shallow 23cm square baking tin with baking parchment. Tip the beans, cocoa, coffee granules, xylitol, vanilla, eggs and yogurt into a large bowl. Blitz using a hand blender until smooth. Or, do this in a food processor. Add the baking powder, then blitz again.
