Heat a saucepan in a low flame and combine coconut milk, peanut butter, chocolate chips, vanilla extract, olive oil and maple syrup. Then, whisk it well until well blended. Later, turn off the flame and let it sit to cool.
Preheat oven at 350 degree Fahrenheit and prepare a 9 inch square baking pan with a greased parchment paper.
In the meanwhile, in a large mixing bowl combine almond flour, coconut flour, hemp seeds, flax meal, cocoa powder, baking powder and salt. Then, mix very well with a spoon until no lumps are left.
Now, add melted peanut butter chocolate mixture, mashed bananas and soaked chia seeds into the dry ingredients.
Thereafter, mix it extremely well with a baking spatula. (You may use your hands if needed).
Now, spoon the dough like batter on the prepared baking pan and spread it evenly with the spatula.
Place the baking pan at the bottom rack of the oven and bake it for 35-40 minutes or until the tester comes out clean.
Let the brownies cool down completely before cutting into desired pieces.
