In a food processor, blitz together the walnuts, two powders and the hemp seeds until it reaches a crumb-like consistency. Remove from the processor and set aside in a large bowl. Blitz the drained prunes, and let the processor break them down a bit before adding the nibs, cinnamon, vanilla extract and berries.

Mix together the dry, crumbly walnut mixture and the sweet prune paste. You could always add a few finely chopped dried apricots or even some lemon zest – this is relaxed baking. It’s up to you.

When the mixture is ready, you have two choices. You can either form it into little balls which you then roll in sesame seeds, or you can press the mixture into a lined baking tin and put it in the freezer before slicing it up later to form little bars.
