3 Ingredient Healthy Peanut Butter Oatmeal Cookies Recipe
Introduction
These 3 Ingredient Healthy Peanut Butter Oatmeal Cookies are a quick and simple treat that combines natural peanut butter, pure maple syrup, and oats for a wholesome snack. Perfect for when you want something sweet without the fuss or added ingredients.

Ingredients
- 1/2 cup (128 g) unsweetened natural peanut butter
- 1/4 cup (59 ml) pure maple syrup
- 1/2 cup + 2 tbsp (50 g) quick oats
Instructions
- Step 1: Preheat your oven to 350°F (177°C) and line a large cookie sheet with parchment paper or a silicone baking mat.
- Step 2: In a large mixing bowl, combine the peanut butter, maple syrup, and oats. Stir until the syrup is fully incorporated and the oats are coated, forming a thick cookie dough.
- Step 3: Scoop 1 tablespoon-sized portions of dough, pack them firmly, and roll each between your palms to form a ball. Place on the prepared sheet and flatten each ball into a disk about 1/4 inch thick using the back of a spoon or your palm. Space cookies about 1/2 inch apart as they do not spread while baking.
- Step 4: Bake for 9-10 minutes, until the surfaces look cooked. Let the cookies cool completely on the sheet before removing to avoid breaking.
Tips & Variations
- Use crunchy peanut butter to add texture or substitute with almond butter for a different flavor.
- Add a pinch of cinnamon or vanilla extract to enhance the taste.
- For chewier cookies, swap quick oats with rolled oats, though baking time might need adjustment.
- Ensure oats are quick oats to keep the cookies soft and hold together well.
Storage
Store the cooled cookies in an airtight container at room temperature for up to 5 days. For longer storage, freeze them for up to 1 month and thaw at room temperature before enjoying. No reheating is necessary, but you can warm them slightly for a softer texture.
How to Serve

Serve this delicious recipe with your favorite sides.
FAQs
Can I use peanut butter with added sugar or salt?
Yes, but using unsweetened natural peanut butter keeps the cookies healthier and lets the maple syrup be the primary sweetener. Added sugar or salt may alter the taste balance.
Do these cookies rise or spread when baking?
No, these cookies do not rise or spread much during baking, so spacing them closely on the baking sheet is fine.
