Preheat oven to 350 degrees.
Grind flax seed (or use flax meal) and combine with water. Allow it to sit for 5 minutes while preparing and measuring the other ingredients.
Combine dry ingredients in a medium bowl- flour, baking soda, salt, baking powder, and cinnamon.
In a medium bowl, stir together wet ingredients: applesauce, honey, canola oil and flax seed mixture.
Slowly incorporate dry ingredients into wet. Then carefully stir in the blueberries. Line muffin tin with papers and spray with oil spray (I use a Misto). Fill muffin tin and bake for about 20-25 minutes or until toothpick comes out clean. Cool and enjoy!
