Begin by preheating your oven to 350°F (175°C). Line a baking sheet with parchment paper to prevent sticking.
In a large mixing bowl, combine the mashed bananas and natural peanut butter. Stir vigorously until the mixture is completely smooth and well integrated.
Next, incorporate the rolled oats, honey or maple syrup, vanilla extract, baking soda, and salt. Stir until all components are fully mixed, creating a sticky cookie dough.
If you’re adding the optional ingredients, gently fold in the dark chocolate chips and chopped walnuts for a delicious burst of flavor and texture.
Using a tablespoon or a cookie scoop, portion out the cookie dough onto the prepared baking sheet, ensuring to leave about 2 inches of space between each cookie for spreading.
Lightly press down on each cookie with the back of a fork or your fingers, flattening them slightly to promote even baking and create a lovely pattern.
Place the baking sheet in the oven and bake for 10-12 minutes, keeping an eye on them until they turn a beautiful golden color and feel firm to the touch.
Once baked, remove the cookies from the oven and allow them to cool on the baking sheet for about 5 minutes. Afterward, transfer them to a wire rack to cool completely.
