Prep & Cook Time

Prep Time: 10 minutes
Cook Time: 15 minutes
Total Time: 25 minutes
Servings: 12 cookies

Ingredients

3 bananas (very ripe, mashed)
½ cup natural peanut butter
1 tsp pure vanilla extract (ensure that your vanilla is gluten-free)
1/3 cup coconut sugar (or maple syrup)
1 ¼ cup gluten-free rolled oats
¾ cup almond flour
1 tsp baking powder
½ tsp ground cinnamon
¼ tsp salt
1/2 cup cacao nibs (optional)
½ cup pecans (or walnuts, or almonds (optional))

Instructions

Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper.
In a large mixing bowl, thoroughly mash the ripe bananas until mostly smooth.
To the mashed bananas, add the natural peanut butter, vanilla extract, and coconut sugar. Stir until the mixture is well combined and creamy.
Add the gluten-free rolled oats, almond flour, baking powder, ground cinnamon, and salt to the wet ingredients. Mix until a cohesive dough forms.
If using, fold in the optional cacao nibs and chopped nuts of your choice.
Scoop about 2 tablespoons of dough for each cookie onto the prepared baking sheet. Use your fingers or a fork to gently flatten each mound into a cookie shape, as they will not spread much during baking.
Bake for 14-16 minutes, or until the edges are lightly golden and the tops appear set.
Allow the cookies to cool on the baking sheet for 10 minutes before transferring them to a wire rack to cool completely. They will firm up as they cool.

Variations

Thinner & Crispier: Flatten the dough balls more significantly before baking for a larger, crispier cookie.
Oat Flour Base: For a more uniform texture, pulse half of the rolled oats into a fine flour before adding them to the dough.
Cookie Bars: Press the entire batch of dough into a lined 8×8 inch baking pan and bake for 20-25 minutes. Slice into bars once cooled.
Flavor Twist: Swap the ground cinnamon for a pinch of nutmeg or cardamom for a different warming spice note.

Tips for Success

Use bananas with lots of brown spots for maximum natural sweetness and easier mashing.
Ensure your baking powder is fresh and labeled gluten-free to keep the recipe celiac-safe.
Let the cookies cool completely on the baking sheet as instructed; this step is crucial for them to hold together.

Storage & Reheating

Store completely cooled cookies in an airtight container at room temperature for 2-3 days, or in the refrigerator for up to a week. For a warm, fresh-from-the-oven experience, reheat a cookie in the microwave for 10-15 seconds or in a toaster oven for a few minutes.

FAQ

1. Can I use regular peanut butter instead of natural?

Yes, but natural peanut butter is recommended for its simpler ingredients and oil content, which affects texture. If using regular peanut butter (with added oils and sugar), the dough may be slightly oilier and sweeter.

2. Why are my cookies too soft or falling apart?

This usually means they needed more baking time or more cooling time. They firm up significantly as they cool. Also, ensure you measured the almond flour correctly; too little can lead to a lack of structure.

3. Can I make these without nuts for allergies?

Yes, simply omit the optional pecans/walnuts/almonds. The recipe will still work perfectly with just the almond flour, which is made from nuts.

4. My bananas aren’t very ripe. Can I still make these?

Very ripe bananas are essential for sweetness and binding. Using less-ripe bananas will result in a less sweet cookie and a dough that may be too dry. It’s best to wait for them to ripen.

5. Are rolled oats and quick oats interchangeable here?

For the best texture, stick with gluten-free rolled oats (old-fashioned oats). Quick oats are more finely cut and will absorb more moisture, potentially making the cookies dense or gummy.

6. Can I use something other than almond flour?

Almond flour provides necessary structure and fat. Substituting it is tricky in this recipe; oat flour is the best 1:1 substitute, but the cookies may be slightly more crumbly.
