Make chewy, bakery-style cookies loaded with peanut butter flavor and colorful M&M candies using this straightforward recipe.

Ingredients

Scale
  • 1 cup unsalted butter, softened
  • 1 cup packed light brown sugar
  • 1/2 cup granulated sugar
  • 3/4 cup creamy peanut butter
  • 2 large eggs
  • 1 tablespoon vanilla extract
  • 2 1/4 cups all-purpose flour
  • 1 teaspoon baking soda
  • 1/2 teaspoon salt
  • 1 1/2 cups peanut butter M&M’s candies

Instructions

  1. Preheat your oven to 350 degrees Fahrenheit. Line baking sheets with parchment paper.
  2. In a large bowl, cream together the softened butter, brown sugar, and granulated sugar until light and fluffy.
  3. Beat in the peanut butter until combined. Add the eggs one at a time, mixing well after each addition. Stir in the vanilla extract.
  4. In a separate bowl, whisk together the flour, baking soda, and salt. Gradually add the dry ingredients to the wet ingredients, mixing on low speed until just combined. Do not overmix.
  5. Gently fold in the peanut butter M&M’s candies.
  6. Drop rounded tablespoons of dough onto the prepared baking sheets, spacing them about 2 inches apart. For thicker cookies, press a few extra M&M’s onto the tops of the dough balls.
  7. Bake for 9 to 11 minutes, or until the edges are set and lightly golden brown. The centers should still look slightly soft.
  8. Let the cookies cool on the baking sheets for 5 minutes before transferring them to a wire rack to cool completely.

Notes

  • For a richer peanut butter taste, use a natural, unsweetened peanut butter.
  • If you prefer a slightly flatter, crispier cookie, chill the dough for 30 minutes before baking.
  • You can substitute regular M&M’s or a mix of peanut butter and regular M&M’s for variety.
