Ingredients

To whip up these delicious Flourless Peanut Butter Banana Oatmeal Cookies, you will need the following ingredients:

2 cups quick oats (225 g)
2 medium ripe bananas, mashed (285 g, approx. 1.25 cups)
1/2 cup natural peanut butter
1-2 tbsp maple syrup or coconut sugar
1/2 tsp sea salt
1/2 tsp pure vanilla extract
1/2 cup dairy-free chocolate chips or chopped dark chocolate (90 g)

Ingredient Notes

Quick Oats: Make sure you use quick oats for the best texture. Old-fashioned oats can also work but may result in a chewier cookie.
Ripe Bananas: The riper your bananas are, the sweeter your cookies will be, enhancing the overall flavor profile.
Natural Peanut Butter: Opt for natural peanut butter without added sugars or oils to keep the recipe healthy and simple.
Sweeteners: You can adjust the level of sweetness according to your taste. Maple syrup gives a hint of caramel flavor, while coconut sugar provides a more butterscotch-like taste.
Chocolate Chips: Feel free to use your favorite type of chocolate—milk, dark, or even white chocolate—as a delightful addition.

Instructions

Preheat your oven to 350°F (175°C).
Mash the bananas in a bowl using a fork until they form a thick, smooth paste. The riper the bananas, the easier this process will be!
Combine the ingredients: Add the rest of the ingredients to the mashed bananas, mixing until everything is combined into a dough.
Shape the cookies: Using a spoon, drop 16 spoonfuls onto a cookie sheet, shaping each spoonful into a cookie shape. Remember, these cookies won’t spread during baking, so create the shape you want beforehand—make them larger and flatter or keep them as a haystack-style.
Bake for 15 minutes. The cookies should be firm and slightly browned when done.

Expert Tips for the Best Results

Banana Consistency: Make sure your bananas are well-mashed for an even texture throughout the dough.
Scoop Size: Use a cookie scoop for uniform cookies that bake evenly.
Watch the Bake Time: Keep a close eye on the cookies toward the end of the baking time to ensure they do not overbrown.
Cool Before Serving: Let the cookies cool on the baking sheet for a few minutes before transferring to a wire rack to cool completely. This helps them firm up further.

Variations

Add Nuts: Chopped walnuts or pecans can add a delightful crunch to your cookies.
Different Nut Butters: Try substituting peanut butter with almond butter or cashew butter for a unique flavor twist.
Additions: Mix in shredded coconut or dried fruit for extra texture and flavor.
Spices: Add a pinch of cinnamon or nutmeg for added warmth and depth.
Cacao Nibs: For a richer chocolate flavor, replace chocolate chips with cacao nibs.

Serving Suggestions

Flourless Peanut Butter Banana Oatmeal Cookies pair wonderfully with a glass of almond milk or a chilly smoothie. Consider serving these cookies with fresh fruit on the side, such as sliced strawberries or a banana, or even a dollop of yogurt for added creaminess. They also make a delightful addition to a picnic basket or a lunchbox treat.

Storage and Reheating

Store your Flourless Peanut Butter Banana Oatmeal Cookies in an airtight container at room temperature for up to 5 days. For longer storage, you can refrigerate them for up to a week or freeze them for up to three months. To reheat, simply pop them in the microwave for about 10-15 seconds or enjoy them cold for a delicious snack.

Common Mistakes to Avoid

Overmixing: Once you combine the ingredients, mix just enough to incorporate everything. Overmixing can result in a dense cookie.
Using Under-ripe Bananas: Ensure your bananas are ripe and spotty for the best sweetness and moisture.
Skipping the Preheating Step: Preheat your oven to ensure an even baking temperature and to set the cookies’ shape right from the start.
