In a small bowl, soak the dates in the apple sauce for 10-15 minutes.
Preheat oven to 375F degrees. Line a 8-inch square baking pan with parchment paper and lightly grease with non-stick spray.
In a medium mixing bowl, whisk together 2 cups oats, cinnamon, nutmeg and baking powder until thoroughly combined.
Add the remaining 1 cup oats, bananas and vanilla to a blender or food processor. Pour the apple juice from the dates into the blender and blend until smooth and creamy. Add the dates to the banana mixture in the blender and lightly pulse until dates are chopped into small pieces.
Pour the blended banana-date mixture into the dry oat mixture and thoroughly mix until all dry ingredients have been absorbed. Stir in the blueberries and chopped nuts (if using).
Pour the batter into the prepared baking pan and smooth into an even layer with a spatula.
Bake for 25-30 minutes, or until a toothpick inserted near the center comes out clean and edges are golden.
Allow pan to cool on a wire rack for at least 10 minutes before cutting into 12 squares. Can be enjoyed warm, at room temperature, or chilled.
Store any remaining oat bars in an airtight container.

Simply spray a 12-cup muffin tin with non-stick spray and fill each cup about 3/4 full. Bake until golden around the edges and a toothpick inserted in the center of the muffins comes out clean.Squares can be individually wrapped for a quick grab-n-go morning breakfast or anytime snack.
