Preheat your oven to 350°F (175°C) and grease a 9x9 or 11x7 inch baking pan.

In a small bowl, combine 2 tablespoons of ground flaxseed with 6 tablespoons of water to create flax eggs. Stir well and let thicken for 5 minutes.

In a large mixing bowl, combine rolled oats, chopped pecans or walnuts, cinnamon, nutmeg, baking powder, and salt.

In another bowl, whisk together unsweetened applesauce, non-dairy mylk, flax eggs, pure maple syrup, and vanilla extract.

Gently fold the wet ingredients into the dry ingredients and add the blueberries.

Transfer the mixture into the prepared baking pan and sprinkle additional blueberries on top.

Bake for 35-45 minutes, checking at 35 minutes for a set center.

Let cool for about 5 minutes before slicing and serve with your choice of toppings.
