Preheat the oven to 350 degrees. Spray an 8×8″ square baking pan with cooking spray and set aside.

Place the eggs in a large bowl and beat lightly with a whisk. Add the applesauce, coconut sugar, coconut oil, vanilla, cinnamon, baking powder, baking soda, and salt and whisk well to combine.

Add the whole wheat and oat flours, stirring until almost combined. Add the blackberries and fold gently until incorporated being careful not to over mix.

Pour the batter into the prepared pan and spread evenly. Top with the pecans if using and bake in the center rack of the oven for 30-40 minutes or until the top springs back when pressed with your finger, or a toothpick inserted into the center comes out clean.

Cool on a wire rack and cut into squares. Enjoy!
