Preheat oven to 350° F In a small/medium bowl, first mix the chia seeds and water together. Then add the rest of the wet ingredients to the bowl. In a larger bowl, add all the dry ingredients and mix together. Pour the wet ingredients into the dry ingredients bowl and mix all together. This is a thick batter, but if it's too hard to mix together then add a little more cashew milk (or whatever milk you're using) then fold in the wild blueberries.
Add the mixture to a greased muffin tin. If you want them on the bigger side fill all the way to the top. For smaller muffins add less batter to each. Bake for 23-25 minutes. Allow to cool before serving.
