5-Ingredient Peanut Butter Oatmeal Cookies (Easy, Healthy & Naturally Sweet!)


  • Author: WAFA LI

Ingredients

Scale
(Makes 12–14 cookies)

The 5 ingredients:

  • 1 cup rolled oats (certified gluten-free if needed)
  • ½ cup natural peanut butter (creamy, unsweetened—no added oil/sugar)
  • ⅓ cup pure maple syrup (or sugar-free maple syrup for blood sugar friendly)
  • 1 large egg (or flax egg for vegan: 1 tbsp ground flax + 3 tbsp water)
  • 1 tsp vanilla extract

Optional boosts (you’ll love these!):

  • Chocolate chips: ¼ cup dark or sugar-free chocolate chips (you love chocolate!)
  • Sea salt: Flaky salt on top before baking (sweet-salty contrast—you love this!)
  • Cinnamon: ½ tsp for warmth

Instructions

1. Mix dough:

In a bowl, combine oats, peanut butter, maple syrup, egg, and vanilla. Stir until thick and sticky. Fold in chocolate chips if using.

2. Chill (optional but helpful):

Refrigerate 10–15 minutes (eases scooping; skip if in a hurry).

3. Bake:

  1. Preheat oven to 350°F (175°C). Line a baking sheet with parchment.
  2. Roll dough into 12 balls; place 2″ apart. Flatten slightly with fork (classic criss-cross!).
  3. Sprinkle with flaky salt if desired.
  4. Bake 10–12 minutes until edges are golden. Cool 5 minutes on pan.
💡 Pro Tips for Perfection:
Use natural peanut butter—stir well before measuring (oil separation is normal!).
Don’t overbake—12 minutes max for chewy centers (they firm as they cool).
