Boil water and allow tea bags to steep in water for 20 minutes.
Combine tea, coconut milk and vanilla extract.
Place chia seeds in a large jar and top with tea mixture.
Put on cap and shake well.
Add in maple syrup and blackberries and place cap back on before giving it another good shake. Mixture will seem liquidy but it will turn into pudding as it sits.
Store in refrigerator overnight or for at least 8 hours.
