In a large mixing bowl, mash ripe bananas with a fork or hand mixer
Add almond butter and eggs to the mashed bananas
Mix the wet ingredients well until smooth and well combined
Add cacao powder, coconut sugar, baking soda, and a pinch of salt to the wet ingredients. Mix until combined.
Gently fold 3/4 cup chocolate chips into the batter
Add the brownie batter to an 8 or 9 inch cast iron skillet (greased). Add the rest of the chocolate chips on top. Swirl a few spoonfuls of almond butter (optional).
Bake for 25 - 28 minutes or until the preferred gooey-ness. Use a tooth pick to insert in the middle to test the doneness of the brownie.
Let it cool for at least 10 minutes then dig in!

Notes
* You can also use sweet potato puree or pumpkin puree.** If using pumpkin puree, add 1/3 cup to 1/2 cup coconut sugar since the pumpkin puree is not as sweet as ripe bananas. But you can always adjust the amount based on your preferred sweet level.
