Ingredients

Scale
  • 2 cups all-purpose flour
  • 1 teaspoon baking soda
  • 1/2 teaspoon kosher salt
  • 6 ounces (11/2 sticks) unsalted butter, softened at room temperature
  • 2/3 cup natural peanut butter
  • 1/2 cup packed light brown sugar
  • 1/2 cup granulated sugar

  • 11/2 cups M&Ms

Instructions

  1. In a medium bowl, combine the flour, baking soda and salt.

  9. Bake for 12-15 minutes until the cookies are light golden brown and cracked on top. Keep them on the pan for 5 minutes before transferring to a rack to cool.

Notes

The cookies are best up to 2-3 days after they are baked. Store them in an airtight container at room temperature.

You can also freeze baked cookies and let them thaw at room temperature.
