1. Heat oven to 180ºC.
2. Put the flour, cocoa, sugar, dark chocolate, orange zest, baking powder and a ½ teaspoon of salt into the Braun Multiquick 5’s chopper accessory and blend to a powder.
3. Add this powder to the eggs in the Braun Multiquick 5 Compact Kitchen Machine with the kneading hook and blend until the mixture forms a dough.
4. Tip the dough onto a counter dusted with flour, add the almonds and knead until smooth. Divide into 4 and shape into flat, rectangles. Lift them onto a
paper-lined baking sheet. Bake for 25 minutes or until a toothpick inserted in the centre comes out clean, then leave to cool.
5. Use a serrated knife to cut the baked dough into bitesize pieces. Place on a clean baking sheet and bake them for a second time for 15 minutes, turning once until crisp. Allow to cool on a wire rack and store for up to 10 days in an airtight container.
