In a bowl or mason jar, stir together chia seeds, milk, maple syrup and vanilla, if using. If you’re using a mason jar, you can put the lid on and shake the mixture to combine everything.
Once the chia pudding mixture is well combined, let it sit for 5 minutes, give it another stir/shake to break up any clumps of chia seeds, cover and put the mixture in the fridge to 'set' for 1-2 hours or overnight.
The chia pudding should be nice and thick, not liquidy. If it’s not thick enough, just add more chia seeds (about 1 Tablespoon), stir and refrigerate for another 30 minutes or so.
Store any leftover chia pudding in the fridge in a covered container for 5-7 days.
