Peanut Butter M&M Cookies

These Peanut Butter M&M Cookies have a soft peanut butter cookie dough studded with creamy Peanut Butter M&M’s. It’s the perfect cookie recipe for the peanut butter lover!

If you’re not familiar with a Peanut Butter M&M, it’s like Reese’s Pieces but even bigger and creamier.

Peanut Butter M&M Cookies

A friend introduced them to me and I was simultaneously very happy and deadly upset over how delicious they are.

They’re the best M&M ever, if you ask me.

This cookie has both amazing textures and intense peanut butter flavor.

I love biting into the soft peanut butter cookie dough, but getting those bits of hard candy shell that yield to the creamy peanut butter centers of the M&Ms.

M&M Cookies

Even though I highly recommend peanut butter M&Ms here, you may use other types of M&Ms.

You can use regular chocolate M&Ms, the peanut M&Ms with the actual nut inside, pretzel M&Ms, and so on.

How to Make Peanut Butter M&M Cookies:

Start by placing brown sugar, granulated sugar, and softened butter in a bowl:

How to Make M&M Cookies

Use a large cookie scoop to portion out mounds of cookie dough.

You may place them on a lined baking sheet to bake immediately, or you can place scoops on a plate and freeze them for later.

After 12-14 minutes in the oven, the dough balls will spread and bake down, with the M&Ms still intact:

I love eating the cookies straight out of the oven, as the centers of the candies get especially creamy and warm.

Monster Cookies are a similar cookie that I also love making, along with SnickerdoodlesShortbread Cookies, and Molasses Cookies. Enjoy!
