Prepare the oatmeal by adding all of the oatmeal ingredients to a medium saucepan over medium high heat. Bring to a rolling boil, then reduce to a simmer, until the oats have absorbed nearly all of the liquid, about 12 minutes.

While the oatmeal is cooking, preheat the oven to 375 and line cavities of two muffin pans with paper liners.

In a medium bowl, whisk together the whole wheat flour, all purpose flour, baking powder, cinnamon, and baking soda. Set aside.

In a large bowl, whisk together the Greek yogurt, applesauce, milk, coconut sugar, and vanilla until combined.

Once the oatmeal has been cooked, add a heaping 1 cup of oatmeal to the yogurt mixture, stirring until combined. Add in the flour mixture and mix until no large lumps remain. Gently fold in the blueberries. (The batter will be very thick)

Scoop the batter into the prepared muffin tins, filling each ¾ of the way full. Bake for 18 minute or until golden brown and the muffins spring back lightly when poked.
