Easy Peanut Butter M&M Cookies

Samantha Erb
My peanut butter M&M cookies have the perfect ratio of peanut butter to M&M's resulting in a soft, chewy, and sweet cookie. I use peanut butter M&Ms for the best flavor!

Ingredients

  • 1/2 cup butter softened
  • 3/4 cup light brown sugar packed
  • 1 large egg
  • 1/2 cup creamy peanut butter
  • 1 teaspoon vanilla extract
  • 1 teaspoon baking soda
  • 1 1/2 cups all-purpose flour
  • 1 cup peanut butter M&M's
  • ½ teaspoon salt

Instructions
 

  • Preheat the oven to 350 degrees F, and then line a cookie sheet with parchment paper.
  • In a large mixing bowl, cream together the unsalted butter and light brown sugar using an electric mixer.
  • Next, add a room-temperature egg, peanut butter, and vanilla extract. Beat all the ingredients together until they are well combined.
  • In a small bowl, whisk together the flour, baking soda, and salt. Gradually add the dry ingredients to the wet ingredients. Mix them until they are just combined.
  • Fold in the peanut M&M's, making sure they are evenly distributed.
  • Cover the bowl with a lid or plastic wrap, and then chill the peanut butter cookie dough in the fridge for at least 30 minutes.
  • Using a large cookie scoop, scoop out the dough and place each dough ball on the prepared baking sheet. Be sure to place them about 2 inches apart.
  • Bake the cookies for 10 minutes or until they are golden brown around the edges. Let them cool on the baking sheet for a few minutes before transferring them to a wire rack to cool completely.

Notes

  • Always use butter and eggs at room temperature so the dough comes together evenly in the mixer and gives the cookies the best texture.
  • To keep the cookies from spreading too much, chill the cookie dough in the refrigerator for at least 30 minutes.
  • Place the cookie dough balls at least 2 inches apart on the lined baking sheet.
  • To avoid hot spots in the oven, rotate the cookie sheet halfway through baking so all my cookies bake evenly.
  • Let the cookies rest on the baking sheet on the counter for a few minutes to help them set and keep them soft.
  • Store leftovers in an airtight container on the counter for a few days or in the freezer up to 3 months.
