Ingredients

Scale
  • 1/2 cup (113g) unsalted butter, softened
  • 1/2 cup (128g) creamy peanut butter
  • 1/2 cup (100g) granulated sugar
  • 1/2 cup (110g) brown sugar, packed
  • 1 large egg
  • 1 teaspoon (5ml) vanilla extract
  • 1 1/4 cups (160g) all-purpose flour
  • 1/2 teaspoon (2g) baking soda
  • 1/4 teaspoon (1g) salt
  • 1/2 cup (90g) M&Ms (regular or mini)
  • 1/2 cup (90g) semi-sweet chocolate chips

Instructions

  1. Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper or a silicone mat, or lightly grease the pan with butter.
  2. In a large bowl, beat the unsalted butter, granulated sugar, and brown sugar until light and fluffy (about 2-3 minutes with an electric mixer). Scrape down the sides as needed.
  3. Mix in the creamy peanut butter, egg, and vanilla extract until smooth and glossy.
  4. In a separate bowl, whisk together the all-purpose flour, baking soda, and salt.
  5. Gradually add the dry ingredients to the wet mixture, mixing on low speed or by hand until just combined. Do not overmix.
  6. Gently fold in the M&Ms and chocolate chips, reserving a few for pressing on top of the cookies before baking.
  7. Using a cookie scoop or heaping tablespoon, drop dough balls onto the prepared baking sheet, spacing them about 2 inches apart. Press extra M&Ms and chocolate chips on top for decoration.
  8. Bake for 9-11 minutes, or until the edges are just golden and the centers look slightly underbaked.
  9. Let the cookies cool on the baking sheet for 5 minutes, then transfer to a wire rack to cool completely. Enjoy warm or at room temperature.

Notes

For thicker cookies, add an extra 2 tablespoons of flour. Chill dough for 20-30 minutes if your kitchen is warm or if using natural peanut butter. Press extra M&Ms and chocolate chips on top before baking for a bakery-style look. Store cookies in an airtight container with a slice of bread to keep them soft. Dough can be frozen in balls and baked straight from frozen with 1-2 extra minutes of bake time.
