Peanut Butter M&M Cookies

The taste is pretty much in the title: traditional peanut butter cookies with m&ms. Very soft peanut butter m&m cookies! I like my cookies soft, so I am glad these turned out that way. I was really into peanut butter for a time there so I decided to add M&Ms to my peanut butter cookies, and they were so good!

How to make excellent peanut butter m&m cookies:

  • mix together wet ingredients and sugars-this helps the sugar become less grainy and it will beat the egg in. You can use a whisk for this part if you do not have a hand mixer
  • stir together dry ingredients-dry ingredients include flour, baking soda, and salt.
  • add dry ingredients to wet ingredients while stirring. Then, add m&ms.
  • scoop out dough onto sprayed baking sheet using a cookie scoop. If you do not have a cookie scoop (we did not have one for many years), use a heaping tablespoon.
  • bake! Look at my notes on the baking instructions.

large mixing bowl
small mixing bowl
dry measuring cups
teaspoon measures
9 x 13 baking sheet


  • 1 stick melted butter
  • 1/2 cup white sugar
  • 1/2 cup brown sugar
  • 1/2 cup peanut butter
  • 1 egg
  • dash vanilla
  • 1 1/4 cup flour
  • 1/2 tsp baking soda
  • dash salt
  • 2 cups M&Ms


  • Mix together butter and sugars for 2 minutes in a large bowl. Add in peanut butter, egg, vanilla, and mix until combined.
  • In a smaller bowl, stir together flour, baking soda, and salt. Slowly add to wet ingredients while stirring. After well combined, stir in M&Ms.
  • Using a cookie scoop, scoop out dough onto a sprayed baking sheet leaving 3 inch spaces between each one so they can grow a little bit. Heaping the cookie scoop is okay in this recipe as they do not expand a ton.
  • Bake for 10-12 minutes at 350 degrees. Remove from oven. Let cookies cool on a wire rack. Serve the Peanut Butter M&M Cookies when cool.


Baking time note: I would recommend setting the timer and checking on these m and m cookies at the 10 minute mark. If they are still soft on the edges, put them back in the oven for a few minutes to firm them up a bit. If they are firm on the edges at 10 minutes, take out of oven. I usually let my cookies cool on the pan on top a wire rack for 1 minute. Then, I remove the peanut butter cookies from the pan and place them on the wire rack to cool.
