Simply combine all of the ingredients together in a bowl. You will find that the coconut flour will start to soak up all of the moisture and thicken the mixture; you want it to be thick but not stiff. The texture will depend a little on the runniness of the tahini too. If it feels too stiff then just add a tablespoon of water.
Transfer the mix into the dish and place in the freezer for at least an hour. Once it has frozen solid remove and cut into squares.
Keep in the freezer and when you are ready to serve just take it out and leave it for 5-10mins to thaw out before eating (or you can eat it frozen which is equally as yummy!)
