Step 1

Preheat oven to 350ºF and line an 8x8" baking dish with parchment paper.

Step 2

Place bananas in a mixing bowl and use a fork to throughly mash. Once pureed, stir in peanut butter, maple syrup, coconut oil, and vanilla.

Step 3

Add rolled oats, collagen or protein powder, chocolate chips, walnuts (if using), and salt; stir to combine.

Step 4

Pour mixture into prepared baking dish and transfer to the oven. Bake for 22 to 24 minutes, or until set. Remove from the oven and let cool in the pan for 30 minutes. Use the parchment paper to lift the bars out of the pan and let cool completely before slicing into.

Step 5

Once cooled, slice into 10 bars. (I also like sprinkling some flaky salt overtop, however this is totally optional!)
