About This Recipe
These cookies have a rich cocoa flavor, a soft and chewy texture from the oats, and just the right hint of peanut butter to tie everything together. They hold their shape beautifully once set and offer that classic no-bake cookie vibe in a smarter, guilt-free form.
They come together in under 10 minutes and need no oven, no fancy equipment, and barely any cleanup. These are great for a quick weeknight treat, lunchbox snack, or even a healthy-ish late-night indulgence.
Why This Recipe Belongs in Your Diet
Swapping out the usual butter for unsweetened applesauce and using just a spoonful of peanut butter keeps these cookies low in fat while still providing that creamy richness. Plus, old-fashioned oats bring fiber and keep you full longer, helping to manage hunger between meals.
What You’ll Need (Ingredients)
We’re using cocoa powder, applesauce, and oats to build flavor and texture without extra fat.
- Old-Fashioned Oats, 2 cups: Give the cookies that classic chewy texture. Avoid quick oats—they’ll get too soft.
- Unsweetened Applesauce, ½ cup: Replaces butter to cut fat and add moisture.
- Natural Peanut Butter, 2 tablespoons: Just enough for flavor and binding, while keeping fat low.
- Cocoa Powder, ¼ cup: Brings rich chocolate flavor without added fat.
- Honey or Maple Syrup, ⅓ cup: Natural sweetness that helps bind the cookies.
- Vanilla Extract, 1 teaspoon: Rounds out the flavor.
- Salt, ¼ teaspoon: Enhances the chocolate and peanut butter.
How to Make Low Fat No-Bake Oatmeal Cookies
- Line a tray with parchment paper or a silicone mat for easy cleanup.
- In a medium saucepan, combine applesauce, peanut butter, cocoa powder, and honey.
- Heat over medium, stirring constantly until smooth and slightly thickened (about 2–3 minutes).
- Remove from heat and stir in vanilla and salt.
- Add oats and mix until evenly coated and sticky.
- Scoop tablespoons of the mixture onto the prepared tray. Flatten slightly if desired.

Recipe Tips and Variations
- For a firmer cookie, use a touch less applesauce or more oats.
- Add 2 tablespoons of mini chocolate chips for a bit of indulgence (adds a little fat).
- Swap peanut butter for almond butter or sunflower seed butter if needed.
