Step 1

Preheat oven to 350°F. Line an 8"x8" baking pan with parchment paper, with enough excess alongside opposite sides so that you can more easily pull out the bars to slice them when they're done. Spray the pan, including the bottom and sides with parchment, with cooking spray and set aside.

Step 2

Add old-fashioned oats, baking powder, cinnamon, and salt to a large mixing bowl. Stir to combine.

Step 3

Add bananas to a medium bowl and beat using a hand mixer until creamy and mostly smooth.

Step 4

Add mashed banana, milk, eggs, maple syrup, and vanilla and maple extracts to the bowl with the oats. Beat together until combined evenly.

Step 5

Stir in nuts and dried fruit.

Step 6

Pour out mixture into the prepared pan and smooth the top. Bake for 45 minutes, or until the edges have browned and the center is set. Let cool in the pan before carefully removing and slicing.
