Ingredients

Scale
  • 1 1/2 cups all-purpose flour (190g)
  • 1/2 teaspoon baking soda (2g)
  • 1/4 teaspoon salt (1g)
  • 1/2 cup unsalted butter, softened (113g)
  • 3/4 cup creamy peanut butter (180g)
  • 1/2 cup brown sugar, packed (100g)
  • 1/4 cup granulated sugar (50g)
  • 1 large egg
  • 1 teaspoon pure vanilla extract (5ml)
  • 1 cup M&Ms (180g)
  • 1/2 cup mini chocolate chips (optional, 90g)

Instructions

  1. Line a large baking sheet with parchment paper or a silicone baking mat. Preheat oven to 350°F (175°C).
  2. In a medium bowl, whisk together flour, baking soda, and salt. Set aside.
  3. In a large mixing bowl, beat softened butter and peanut butter until smooth (about 1 minute on medium speed).
  4. Add brown sugar and granulated sugar. Beat until light and fluffy, about 2 minutes.
  5. Beat in egg and vanilla extract until fully incorporated.
  6. Add the flour mixture in two additions, mixing on low speed just until combined.
  7. Gently fold in M&Ms and mini chocolate chips (if using) with a spatula. Save a few M&Ms for pressing on top.
  8. Use a medium cookie scoop (about 1.5 tablespoons) to portion dough onto prepared baking sheet, spacing cookies about 2 inches apart.
  9. Press reserved M&Ms gently onto the tops of each dough ball.
  10. Bake for 9-11 minutes, or until edges look set and centers still look slightly underbaked.
  11. Let cookies cool on the baking sheet for 5 minutes, then transfer to a wire rack to cool completely.

Notes

For extra soft cookies, do not overbake—remove from oven when edges are set but centers look slightly underdone. Store cookies in an airtight container with a slice of bread to keep them soft. You can customize with different mix-ins like mini chocolate chips, butterscotch chips, or use holiday-themed M&Ms. For gluten-free, substitute a 1:1 gluten-free flour blend. If cookies spread too much, chill dough for 15-20 minutes or add extra flour.
