- 1/2 cup natural creamy peanut butter (unsweetened)
- 2 cups rolled oats
Add-ins
- 1/2 cup chocolate chips (or dried fruit)
Instructions
- Preheat Oven: Preheat your oven to 350°F (175°C) and line two baking sheets with silicone baking mats or parchment paper to prevent sticking and for even baking.
- Mix Wet Ingredients: In a large bowl, combine the mashed ripe bananas and natural creamy peanut butter. Stir thoroughly until you have an even, smooth mixture.
- Add Oats: Add the rolled oats to the banana and peanut butter mixture. Stir well until the oats are fully incorporated and the batter is evenly mixed.
- Incorporate Add-ins: Fold in the chocolate chips or dried fruit, ensuring they are evenly distributed throughout the cookie batter.
- Shape Cookies: Using a 1 ½ tablespoon cookie scoop, portion the batter onto the prepared baking sheets, spacing the cookies about 2 inches apart. Flatten each scoop with the palm of your hand to your desired thickness and shape, as the cookies won’t spread during baking.
- Bake: Bake the cookies in the preheated oven for about 10 minutes, or until they are set and lightly firm to the touch.
- Cool: Remove the baking sheets from the oven and allow the cookies to cool completely before transferring them off the sheets. This ensures they hold their shape and texture.
Notes
- Use fully ripe bananas for optimal sweetness and moisture.
- For a vegan version, ensure the chocolate chips are dairy-free.
- You can substitute dried fruit for chocolate chips for a different flavor profile.
- Pressing the cookies before baking is necessary as they do not spread while baking.
