Monster cookies might be the best cookies I’ve ever made. These oversized treats are thick, chewy, and packed to the brim with M&M’s and chocolate chips.
I’m new to the world of Monster cookies—I hadn’t even heard of them until a few months ago. But once I did, I knew I had to make up for lost time. These cookies have it all: peanut butter, oats, M&M’s, and chocolate chips. So many of my favorite things, all in one glorious oversized cookie.
Key Ingredients
By definition, a Monster cookie includes oats, peanut butter, M&M candies, and chocolate chips, but the specific types you choose will greatly impact the final result.
- Oats: Old-fashioned rolled oats give the cookies the perfect texture and chewiness.
- Peanut Butter: For baking, it’s usually best to use a more processed peanut butter like Jif or Skippy. I experimented with both crunchy and smooth varieties and found that smooth peanut butter created a better texture with the oats. Crunchy will work too, but it results in a coarser texture.
- M & M Candies: There’s a pre-made mix of regular, Peanut, and Peanut Butter M&M’s that works beautifully in these cookies, these give an extra boost of flavor. Any M&M’s or similar candy will work.
- Chocolate Chips: I accidentally bought mini chocolate chips, and they turned out to be a fantastic choice. The mini chips distribute evenly throughout the cookie and complement the larger-sized candies.

What makes these Monster Cookies so great!
Quick:These cookies come together in under an hour, including baking time. No need to chill the dough.
Simple: No special instructions or steps are needed. Mix the dry ingredients together, then cream the butter and sugar. Add in the egg and vanilla, stir in the dry ingredients and fold in the M&M’s. The hardest part is not eating the cookie dough!
Flavor: The combination of peanut butter, oats, mini chocolate chips, and three types of M&M’s makes every bite packed with flavor and texture.
Oversized: These cookies are bigger than your average cookie, but not so big you have to share. I use my largest 3 tablespoon cookie scoop for these.
Monster Cookie Storage
The cookies will last up to a week in an airtight container (if you can resist eating them all before then!). To freeze, portion the cookies and place them on a parchment-lined baking sheet. Once frozen, transfer them to a Ziploc bag for up to three months. No need to thaw—just add about 5 extra minutes to the baking time.
Top Tip
If the cookies are not spreading, pull the baking sheet out of the oven halfway through baking and tap it a few times on the counter to help encourage them to spread.
