Preheat oven to 350 degrees and prepare an 8x8’ baking dish by first spraying with non-stick spray, then lining with 2 pieces of parchment paper (cut to the width of the pan) to create a "sling" (You will cross these over each other) and then spray again lightly with non-stick spray. Set aside.
In a medium-large sized bowl combine oats, baking powder, cinnamon and salt.
Mix together.
To your oat mixture add milk, applesauce, maple syrup, butter and vanilla extract.
Mix together until it’s a uniform mixture. Then, if using, fold in your fruit.
Pour your baked oat “batter” into the prepared baking dish. If using, top with chopped nuts.
Spread it evenly so the oat batter is packed tightly.
Bake for 45-50 minutes or until oats are set and the top is golden brown.
Allow your oats to cool fully before cutting to ensure nice even, clean cuts. Enjoy!
