Big Peanut Butter M&M Cookies

I don’t know about you, but there’s something about a big, bakery-style cookie I just can’t resist. Especially when peanut butter and chocolate are involved. And besides being absolutely delicious, these Big Peanut Butter M&M Cookies are just fun!

I definitely think all those colorful M&M’s are part of what makes these cookies so irresistible. And peanut butter cookies are right up there with chocolate chip when it comes to my all-time favorites.

Even better, these cookies are so easy to make! This is definitely a recipe where you want to get the kids helping in the kitchen.

Of course, if you don’t want such a big cookie, you can always make these a more traditional size. Just cut down on the cooking time a few minutes to compensate.

You don’t have to stick with regular old M&M’s either–there are so many flavors to choose from these days–just make sure you choose something that goes well with peanut butter.

If you’ve ever signed up to bring treats for the school bake sale, this recipe is definitely a winner!

Like I said, this is the kind of cookie people find hard to resist, and they’ll sell like hotcakes. Or like amazingly delicious cookies!

As with any homemade cookie, be sure not to over bake these, and let them cool on the cookie sheets for at least 5 minutes before moving them to a wire rack to cool completely. Then pour yourself a big glass of cold milk and enjoy!

Don’t forget to save this recipe to your favorite Pinterest board for later.
