These chewy monster cookies combine the richness of peanut butter, the hearty chew of oats, and colorful bursts of M&Ms for a nostalgic, crowd-pleasing treat that’s quick and easy to make.

Ingredients

Scale
  • 1 cup (240g) creamy natural peanut butter
  • 1 cup (200g) packed light brown sugar
  • 1/2 cup (100g) granulated sugar
  • 1 large egg, room temperature
  • 1 teaspoon vanilla extract
  • 1/2 teaspoon baking soda
  • 1/4 teaspoon salt
  • 2 cups (180g) old-fashioned rolled oats
  • 1 cup (175g) M&Ms

Instructions

  1. Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper or a silicone mat.
  2. In a large bowl, combine peanut butter, brown sugar, and granulated sugar. Beat with an electric mixer or sturdy spoon until smooth and creamy, about 2-3 minutes.
  3. Add the egg and vanilla extract to the mixture. Mix well until fully incorporated and glossy.
  4. In a separate small bowl, whisk together baking soda, salt, and rolled oats.
  5. Gradually add the oat mixture into the peanut butter mixture. Stir gently until just combined; the dough will be thick and sticky.
  6. Fold in the M&Ms gently to avoid crushing them.
  7. Use a cookie scoop or tablespoon to drop 12 evenly sized mounds onto the prepared baking sheet, spacing about 2 inches apart.
  8. Bake for 10-12 minutes until edges look set but centers are still slightly soft.
  9. Let cookies rest on the baking sheet for 5 minutes, then transfer to a cooling rack to cool completely.

Notes

If dough feels too dry, add a tablespoon of milk or water. Do not overbake to maintain chewiness. Store cookies with a slice of bread to keep soft. Dough can be chilled for 30 minutes to improve shape and flavor. Use certified gluten-free oats for gluten-free version. Substitute M&Ms with dairy-free candy or chocolate chips for dairy-free option.
