Blend dates, peanut butter and oats until the ingredients have broken down and are combined.
(Omit this step if using medjool dates). Add 1 Tbs of milk and blend briefly to combine. If mixture is still quite dry, add another Tbs of milk.
Pour mixture into a small lined tupperware container or similar (such as a small brownie pan) and place in the fridge to set for approximately 30 mins - 1 hour. Then cut into 6-9 bite size pieces to enjoy.
