First, preheat the oven to 350 degrees Fahrenheit. Line a standard bread loaf pan or small pan with parchment paper.
Add the ripe bananas, eggs, cocoa powder, and baking soda to a blender. Blend until smooth and creamy.
Pour this mixture into the prepared pan. Garnish with chocolate chips if desired.
Then, bake for 25 to 30 minutes or until a toothpick inserted comes out with only moist crumbs.
Finally, remove from the oven. Allow the sugar free brownies to fully cool before slicing and serving!
