Shake up the can of coconut milk really well and measure out 1/2 cup (unless you're doubling the recipe, then you'll need 1 cup).
Add to a blender with the regular milk, vanilla and optional sweetener. (see notes for how to make this without a blender)
Add in the chia seeds and pulse 2-3 times in the blender to combine. Let it sit for a minute or two, then pulse again.
You just want to combine the ingredients, you don't want to fully blend the chia seeds.
After another minute, pulse again. This will help prevent any clumps of chia seeds from forming and will help the pudding thicken faster than simply mixing everything together in a jar.
After about 5 minutes of occasional pulsing, transfer to a bowl, container or jar and let sit in the fridge for about an hour to thicken.
Serve with yogurt, berries, granola & enjoy!
