Thaw the blackberries.
Mix with the milk, I used this..
..add the chia seeds..
..cinnamon (or cardamon)..
..bourbon vanilla powder and agave syrup. Stir and pour into a glass jar or a glass.
Keep in the fridge, preferably overnight but stir after about 15 min. to avoid lumps.
Serve with a few blackberries and, if you fancy it, some peanut butter.
