In a large mixing bowl, whisk together the flour, cake mix, sugar, baking powder, baking soda and salt. Set aside.
Now in a small bowl add the flax and water and mix together to make flax eggs.(this is equal to 2 eggs). Let sit for a second to thicken.
Now in a medium bowl, whisk together the flax eggs, vanilla, almond milk and vegetable oil. Fully combine, then pour into the large mixing bowl with the dry ingredients.
Whisk together the wet and the dry ingredients until fully combined. Now stir in the sprinkles. Use 1/3 of a cup if you want less sprinkles and 1/2 a cup if you want a lot of sprinkles.
Heat your waffle iron, spray with non stick spray and pour about 1/3 c. of batter into the waffle iron. Cook according to the waffle iron's instructions. Serve immediately with maple syrup or coconut whipped topping and more sprinkles.
