In a mixing bowl, mash your bananas. Now add all other ingredients and fold in. Leave about 20-30 grams of Chocolate chips aside for the last step.
Now we will form the little dough balls, line a baking tray with parchment paper. Using a spoon scoop a ball of cookie dough the size of a large walnut and roll between the palm of your hands to form a dough ball. Place on the baking tray leaving apx 2-3 centimeters or 1 inch of space between each cookie and the edge of the tray. Using your fingers lightly press down on the cookie balls to form a cookie shape.
Last but not least, add chocolate chip sprinkles and bake at 175 C or 300 F for 10 to 12 minutes until golden brown. Set on a cooling rack until they reach room temperature.
