How to Make 3 Ingredient Banana Oatmeal Cookies Without Sugar or Flour

3 ingredient banana oatmeal cookies combine mashed ripe bananas, a fresh egg, and rolled oats to create a healthy, flourless snack baked in under 15 minutes. With zero added sugar, artificial sweeteners, or wheat flour, these cookies deliver a light, naturally sweet chew that satisfies late-night cravings or morning snack needs.

Why Banana, Egg, and Oats Function Without Flour or Sugar

Creating structured cookies without traditional baking ingredients like granulated sugar, butter, or white flour relies on natural binding mechanics. Ripe bananas serve two primary purposes: they provide natural fructose for mild sweetness and supply soluble fiber and moisture that hold dry ingredients together. As bananas ripen, their complex starches convert into simple sugars, giving the cookie dough a soft consistency without relying on refined sweeteners.

The addition of an egg introduces crucial structural protein. When heated in the oven, egg proteins coagulate, trapping moisture and forming a firm structure that prevents the cookie from crumbling. Meanwhile, rolled oats absorb the liquid from both the mashed banana and the egg. As the oats swell and bake at 180°C (350°F), the outer layer crisps while keeping the center soft and chewy.

Ingredients and Preparation Breakdown

Core Recipe Ingredients

• Banana: 1 large ripe banana (spotted brown skin yields best sweetness).
• Egg: 1 large whole egg.
• Oats: 60 to 80 grams (approx. 3/4 cup) rolled oats or quick-cooking oats.

Step-by-Step Cooking Instructions

1.Mash the Banana:Break down natural starches into a smooth mash.

Peel 1 ripe banana and place it in a medium mixing bowl. Use a sturdy fork to thoroughly mash the banana until it reaches a smooth, liquid-like consistency with minimal lumps.

2.Whisk in the Egg:Incorporate natural proteins to bind the batter.

Crack 1 whole egg into the mashed banana. Stir vigorously with a fork or small whisk until the egg is fully incorporated into the fruit mash.

3.Fold in Rolled Oats:Allow oats to absorb liquid for optimal density.

Measure 60 to 80 grams of rolled oats and fold them into the banana-egg mixture. Mix well until all oats are evenly coated, then let the batter rest for 2 minutes to allow the oats to absorb excess moisture.

4.Shape and Bake:Bake at 180°C until edges achieve golden crispness.

Line a baking sheet with parchment paper. Scoop tablespoon-sized portions of batter onto the sheet and flatten them slightly into cookie disks. Bake in a preheated oven at 180°C (350°F) for 12 to 15 minutes until the edges are light golden brown. Remove and cool slightly before serving.
