In a world filled with overly processed snacks, artificial sweeteners, and long ingredient lists, finding a truly wholesome treat that’s both satisfying and simple can feel like an impossible quest. But what if you could create a delicious cookie that’s gluten-free, refined sugar-free, and made with only three nourishing ingredients? This recipe is not only real—it’s also shockingly easy, wonderfully tasty, and healthy enough to enjoy any time of day, even as a quick breakfast or post-workout snack.
Whether you’re managing gluten intolerance, looking for kid-friendly snacks, or just trying to make healthier food choices without giving up dessert, these cookies check all the boxes. They’re soft, naturally sweet, customizable, and come together in under 20 minutes. With only three whole-food ingredients, you can feel good about what you’re putting in your body, and even better about sharing them with your family.
The Three Simple Ingredients
This gluten-free cookie recipe is based on a timeless combination of three pantry staples:
1. Ripe Bananas
Naturally sweet and full of fiber, potassium, and vitamin B6, bananas provide moisture and binding power without the need for eggs or added sugar. The riper the banana, the sweeter the cookies—so those spotty bananas on your counter are perfect for this recipe.
2. Rolled Oats (Gluten-Free)
Oats are rich in soluble fiber, especially beta-glucan, which supports heart health, digestion, and balanced blood sugar. Make sure to choose certified gluten-free oats if you’re avoiding gluten completely. They give the cookies a chewy texture and wholesome flavor.
3. Nut Butter (Peanut, Almond, or Sunflower Seed Butter)
Nut butter provides healthy fats, protein, and a creamy texture that helps hold everything together. Choose natural, unsweetened varieties to keep the cookies clean and low in added sugars. You can use almond butter for a more neutral taste or peanut butter for a nostalgic twist.
These three ingredients combine into a dough that’s moist, sticky, and surprisingly indulgent. From there, you can customize to your heart’s content—or enjoy them as-is for a clean, minimalist treat.

Why These Cookies Are So Good for You
Digestive Health
The combination of bananas and oats creates a fiber-rich snack that supports regularity and gut health. Soluble fiber feeds good bacteria, while insoluble fiber helps move waste efficiently.
Energy Boosting
These cookies offer a balanced combination of carbohydrates from oats and bananas, protein from nut butter, and healthy fats. This trio keeps blood sugar stable and provides long-lasting energy—ideal for mornings, workouts, or afternoon slumps.
No Refined Sugar
Unlike most store-bought cookies loaded with sugar and preservatives, this version is naturally sweetened by bananas alone. Even kids will love them without needing added syrups or sugars.
Kid-Approved and Allergy-Friendly
Because they’re egg-free, dairy-free, and gluten-free, these cookies are safe for a wide range of dietary needs. They’re soft enough for toddlers, simple enough for teens to make, and healthy enough for parents to feel great about serving.
Mood and Brain Support
Bananas and oats contain tryptophan and vitamin B6, which help produce serotonin—a feel-good neurotransmitter. Nut butter adds vitamin E and omega-3s, supporting cognitive health.
Creative Ways to Enjoy These Cookies
On-the-Go Breakfast: Pair a couple of cookies with herbal tea or almond milk for a fast, balanced morning meal.
Post-Workout Snack: Add a scoop of protein powder to the dough for a quick recovery snack that nourishes muscles.

How to Make It Your Own
While the original recipe is wonderful on its own, this cookie dough is a blank canvas for your creativity. Some great variations include:
Chocolate Banana: Add raw cacao powder or cocoa nibs for a more decadent experience.
Apple Cinnamon: Mix in grated apple and a dash of cinnamon.
Tropical: Use coconut flakes and chopped dried pineapple for a beachy flavor.
