Preheat oven to 350 degrees F
Have a 9 x 13 baking pan or casserole dish ready. If need be grease if not non stick.
In a bowl, mix the wet ingredients and let stand for 5 minutes to allow the milk to curdle. If you are using Almond or other plant based milk that is low in protein, it won't curdle as much, but don't worry.
In a large bowl mix your dry ingredients, add the wet and mix to combine. Add the blueberries.
Pour into your pan and bake for 30=40 minutes depending on your preferred doneness.
