Start by mincing the nuts to small pieces in the food processer then set aside
Remove the pits from the dates if you haven’t already. Place them in the food processor and run until you have a sticky dough
Add all remaining ingredients except cinnamon and mix together so it forms a big ball
Split the ball in two and place one on parchment paper and press out to a rectangular disc of around ½ cm thick (1/4 of an inch)
Mix the other half with the cinnamon and then press it out on top of the other layer
Roll it together and wrap it in plastic wrap before storing it in the freezer for at least 1 hour. After that then you can cut it up in slices (around 1 cm thick / ½ inch) and then place it back in the freezer or serve it directly.
