Grease and line the base and sides of a 11 x 21cm (base measurement) loaf pan, allowing sides to overhang. Place the dates, cacao powder, coconut oil, LSA, orange juice and orange rind in a food processor and process until smooth and well combined. Transfer to a large bowl. Stir in the cranberries and pistachio.

Dust a little extra cacao powder over base of prepared pan. Spoon in date mixture and use a greased spatula to smooth the surface. Place in fridge for 8 hours or overnight until firm. Remove from pan. Use a hot, dry knife to cut into squares (mixture will be sticky). Dust with cacao powder.
