Step 1

Preheat oven to 350 degrees F (177C) and line an 8x8 baking pan with parchment paper.

Step 2

In a mixing bowl whisk together the oat flour, cocoa powder, baking soda, cinnamon and salt.

Step 3

Place the bananas in a small bowl, and mash with a fork. It's fine to have a few larger pieces remaining. Measure to make sure you have 1 cup of mashed banana. Add the maple syrup, coconut sugar, vanilla, and almond butter, and stir vigorously until combined.

Step 4

Pour the wet mixture into the dry, and stir to combine. Fold in the walnuts.

Step 5

Transfer batter to the prepared pan, and bake for 28 to 31 minutes or until a toothpick inserted in the center comes out clean.

Step 6

Let brownies rest in the pan for 30 minutes, then lift out by parchment paper. Allow to cool completely before cutting into 16 squares.
