I’ve created the absolute most fool-proof way to make peanut butter M and M cookies. Most people don’t bring their egg to room temperature before making the batter resulting in a gritty cookie that’s not fluffy. That’s not a problem here!

Being the cookie lover I am, I made this cookies fluffy but chewy for the ideal texture.

At this point, I have several dozen cookie recipes to choose from… cake mix crinkle cookies, chocolate chip snowball cookies, and oatmeal cookies are just a few.

Tips for Making Peanut Butter M and M Cookies

  • Make sure your egg and butter are at room temperature before starting. This will give you a smoother cookie dough.
  • Don’t skip chilling the dough in the fridge for at least 30 minutes. This step allows the dough to firm up, which makes it easier to handle and prevents excessive spreading during baking.
  • Place cookie dough balls about 2 inches apart on the baking sheet. This keeps them from spreading into each other while baking.
  • Rotate the baking sheet halfway through baking if your oven has hot spots to ensure even browning.
  • Let your peanut butter M and M cookies rest on the baking sheet for a couple of minutes after removing them from the oven. This helps them set and keeps them soft!

Variations to Peanut Butter Cookies with M&Ms

  • You can swap out M&M’s with chocolate chips or another type of candy. Chocolate chunks, white chocolate chips, or Reese’s Pieces are all great ideas! 
  • After baking, drizzle some melted chocolate over the peanut butter cookies with M&Ms for an extra layer of chocolaty goodness.
  • Get creative with royal icing! Write personalized messages or create fun designs on your cookies to make them truly unique. Again, so fun for the holidays or for a birthday!
  • Sprinkle crushed nuts like almonds or walnuts on top while the cookies are fresh from the oven for an extra crunch.

How Do I Make My Peanut Butter Cookies Chewy?

For the best texture, make sure your ingredients are at room temperature before starting your peanut butter M&M cookies. Also, refrigerate the dough for a minimum of 30 minutes before baking. 

Bake the cookies for around 10-12 minutes, or until the edges are golden and they reach the point of being just set.

Can I Use Any Type of Peanut Butter for this Peanut Butter M&M Cookie Recipe?

I personally swear by creamy peanut butter for cookies. 

That said, if you prefer a stronger PB flavor plus an added crunch, feel free to experiment with crunchy peanut butter. You just need to make sure it’s not too oily — stir it really well before incorporating it into the cookie dough batter.

What to Serve with Peanut Butter M&M Cookies

These peanut butter cookies with M&Ms are wonderful on their own! 

But if you’re in the mood for something really indulgent, consider adding some Peanut Butter Icing or eating them with Peanut Butter Mousse on the side for a totally PB-packed dessert.

You could also add them to an ice cream sundae or use them to make cookie ice cream sandwiches. You can even create a snack platter with Cool Whip Fruit Dip and other sweet treats!
