Preheat your oven to 350 degrees F.
Lightly oil an 8x8 inch baking pan with coconut oil.
Line it with a strip of parchment paper.
In a medium bowl, combine mashed bananas, almond butter, coconut oil, almond milk, sugar, and salt.
Mix until it's smooth with just a few lumps.
Divide the mixture in half.
Mix cocoa powder and chocolate chips into one half.
Stir well!
Pour the plain batter evenly into the prepared pan.
Then, spoon the chocolate batter on top.
Step 5:
Use a knife to swirl through the layers and create a marbled effect.
