This recipe is adapted from the recipe featured on the back of Joy Ice Cream Cone boxes. Joy sells a special baking and storage pan that fits the cones perfectly, but I’ve found that a popover pan works perfectly. (And a regular cupcake pan should work, too—you may need to use aluminum foil to stuff the pan so the cones don’t shift too much in the oven.)
Healthy chocolate brownies
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.
