One Giant Monster M&M Cookie.

Sometimes you just have a giant peanut butter craving. Mixed with a giant M&M craving, a giant chocolate craving, and a giant cookie craving. So… why fight it?

Before I left for St. Lucia last weekend (what a wonderful trip!!), I surprised Kevin with an extra large cookie when he got home from work.  No reason really – I just personally needed a large cookie and I knew he’d want to share. Although sharing something like this is rather difficult.  Perhaps I should be called fiancé-of-the-year.

The thing is, I love making giant cookies!  And if you have been reading SBA for awhile, you may already know about my affinity for making (and eating) them. The giant cookies are perfect for sharing OR gobbling up all by yourself if you’re extra hungry.

You can make them in less than 25 minutes too! They are each completely oversized and ridiculous in the best way possible:

My giant cookie collection was just begging for a monster cookie. Not sure what a monster cookie is? It’s an oatmeal cookie with peanut butter, M&Ms, and chocolate chips. The monster cookies I prefer, however, are more like peanut butter cookies with oats, not oatmeal cookies with peanut butter.

Still with me?

The cookie isn’t as large as a pizza pie. It’s about 4 regular size cookies combined into one. It’s thick, chewy, and completely irresistible. But that goes without saying, right? Just like my full batch of soft-baked monster cookies, today’s XXL monster cookie will stay soft for days. Well, that’s only if it lasts that long. And trust me, it won’t.

This recipe is like any cookie recipe, just downsized.  A few tablespoons of this, a few tablespoons of that. All of your usual monster cookie suspects: flour, oats, butter, peanut butter, white sugar, brown sugar, baking soda, chocolate chips, and egg. Oh and lots of M&Ms. A note for the egg: all you have to do is crack an egg, beat it, and use 2 Tablespoons of the beaten egg. The ingredients are mixed by hand – no electric mixer needed! That’s my kind of last minute dessert.

If you like cookies, if you like peanut butter, if you like M&Ms, and if you have any sort of sweet tooth – what are you waiting for?

1 Giant Monster M&M Cookie

One giant peanut butter M&M cookie to cure even the largest peanut butter cookie craving!

Yield: 1 large cookie

Ingredients:

  • 2 Tablespoons unsalted butter, softened
  • 2 Tablespoons granulated sugar
  • 2 Tablespoons light brown sugar, packed
  • 2 Tablespoons beaten egg (crack an egg, beat it, and use 2 Tbsp)
  • 1/2 teaspoon vanilla extract
  • 2 Tablespoons creamy peanut butter (if using natural peanut butter, use a thick no-stir variety)
  • 6 Tablespoons all-purpose flour
  • 2 Tablespoons old-fashioned rolled oats (or quick oats)
  • 1/4 teaspoon baking soda
  • 1/8 teaspoon salt
  • 1/3 cup M&Ms
  • 2 Tablespoons milk or semi-sweet chocolate chips

Directions:

Preheat oven to 325F degrees. Spray baking sheet with nonstick spray or line with a silicone baking mat. Set aside.

In a large mixing bowl, whisk the butter and sugars until creamed. Add egg and vanilla mixing until well combined. Stir in peanut butter then add flour, oats, baking soda and salt. Fold in M&Ms until combined. With a large spoon, scoop into a ball onto prepared baking sheet. The dough will be sticky. Make sure the cookie dough ball is tall and round. Press the chocolate chips into the top of the cookie.

Bake for 20-22 minutes, until edges are lightly browned. The center may appear undone, but it will set as the cookie cools. Let cool ON the baking sheet for 10-20 minutes.

*You may make four smaller cookies using this recipe. Just divide the dough into 4 smaller mounds on the cookie sheet rather than 1 large mound. Bake for 8-10 minutes.

      or could the dough be refrigerated for a few days prior to baking? i want to make them in advance then bring the dough to my dads house for fathers day so we can hang out and have freshly baked ones on fathers day without all the fuss of making them and all the dishes, just pop em on a pan and stick em in the oven.

        Hi Jenni – this recipe is for just ONE cookie, not sure if you realize that? You can make the dough and refrigerate it. Then bring to room temperature before baking the cookie.

    Oh Sally…..
    Yet another excellent recipe! So far I have made about 5 of your recipes and they are all delish! This morning I made this cookie. I actually made 2 of them! I substituted heath toffee bits since I did not have M&M’s and they turned out great! I can’t wait to try it with M&M’s though. Thank you some much for taking the time to share! I am addicted to your blog! My husband and kids are not too upset about my obsession!

    So i found your pin on Pintrest of course :) and i tried baking your giant cookies for a Fathers Day gift to my husband as he loves all things SWEET lol. I had trouble getting the cookie to spread, and bake in the middle. I eventually lowered the amount of flour used and it began to spread however– the middle still was left wayyy undercooked, but the cookie it self was becoming really golden/brown.. any suggestions?

    Reply

    • Sallyreplied on June 17th, 2013 at 1:24 pm

      Hi Christina! Do you own an oven thermometer? It sounds like your oven temperature may be off. My oven temperature is actually 20 degrees warmer than what the dial states, so I need to adjust accordingly to have my baked goods cook evenly. You could also very loosely cover the cookie with aluminum foil (sort of like a tent, not touching the cookie) to prevent the sides from getting too brown. OR just lower your oven temp by 25 degrees.

    Hi Sally! I’d like you to know that I LOVE your blog, and have made your XXL cookies more times than I’d like to admit. If I may ask a few questions – could the AP flour be substituted with whole wheat flour, completely or partially? And, for the monster cookie and the PB cookie, could the PB be substituted with Biscoff/cookie butter?
    I’d also like you to know that your XXL cookies are the perfect size for my 6-inch mini skillet :) I usually melt 1/3 teaspoon butter in the skillet to lightly coat, then dump in the dough. They cook a bit longer, but it’s totally worth it – all the better with a giant scoop of ice cream on top!
    Thanks for inspiring me :) keep the wonderful recipes and tips coming.

      Hey Nicole! So glad you follow my blog. And what great questions! Yes, WW flour may be used. The cookie may not be as soft, though. Cookie butter/biscoff may be used to replace the peanut butter, yes. I need to try this with ice cream on top. Why on earth I haven’t tried that yet is beyond me. ;) Thanks for the suggestion!

    Hi Sally, i have practiced your recipe. But i used margarine, caster sugar, chopped cooking chocolate, and Delfi instead of butter, brown sugar, choco chip, and M&M. With this recipe, i got 6 medium sized cookies (around 8 cm), which i shared to my friends. And i doubled the baking time to make them crunchier ;p I love the cookies, but the colorful chocolate is too sweet. But it’s ok. I’m happy with this experiment… and this is it, my Cute and Colorful Monster Cookie http://masak-masakan.blogspot.com/2013/06/cute-and-colorful-cookies.html. Thanks Sally :)

    4 in 4! This is the fourth recipe I’ve tried from your site and once again we have a winner! I left out the oats as I didn’t have any on hand. But the cookie tasted WONDERFUL and was the perfect antidote to the time of the month cravings I had been having (I hope that isn’t TMI :/)

    At any rate I will be making this again. As an fyi – - I used the regular size M&M’s as that’s all I had and it didn’t seem to affect the outcome and the cookie it so big the regular size worked fine. I did use the natural peanut butter from Trader Joe’s that I keep in the fridge so it expanded a bit more and was a little larger than expected. But that just meant leftovers for the next day!

    Thank you again for sharing yet another recipe that I can add to my staple :)

    So my post comes from Germany, man you really get responses from all over the world. :)
    I had to convert the measurements as well but it was no big deal and oh how I love your giant cookies! So far I’ve made three – the sugar, the death by chocolate and the monster one.

    Sad thing, I’ve got a little trouble with the dough when I put it on the baking sheet. I really try to do it like your picture shows but in the end my cookie ends up really thick, it doesn’t spread that much while being in the oven… Do you have any suggestions on how I could solve that? The cookies taste great, I would just really like them to look a little bit nicer… :)

    Thanks so much! You and your baking addiction are a great help :)

      Hi Jana! So nice of you to say hello. For this cookie, I suggest making a flatter “ball” of dough. Sort of like a huge disc, not a ball if that makes sense. Also, you can flatten out the edges and the center when you remove it from the oven if it is too thick for you. There is not much room for changing the ingredients in the recipe, so that’s why I suggest changing the way it’s shaped.

    Any idea what size this bakes into? 5″? 8″ Attempting a pb cheesecake/brownie/pb cookie layer cake for a birthday and trying to get each layer the same size. It looks about 5″, do you think doubling the recipe and still making one cookie would bake up the same?

    • Sallyreplied on September 12th, 2013 at 11:18 am

      Hi Anne! It’s about 6 inches. I fear the cookie would considerably spread if doubled and baked free-form on a cookie sheet. However baked in a pan, it should be fine. Your layer cake sounds amazing!

    Hi Sally!
    I am sooo in love with your website! I’ve already tried several of your recipes….all delicious! I have one question: what would you say is the best substitute for butter or oil when baking? I try to lighten up your recipes when I’m feeling guilty about splurging, but I’m not always sure of how to do so. I realize the flavor/texture may change, but I’m fine with that. Do you recommend applesauce, Greek yogurt, a butter substitute, and does the substitute depend on the type of recipe (cookies, bars, etc)? Let me know what you think is best! Thank you!

    Reply

    • Sallyreplied on October 4th, 2013 at 5:15 pm

      Hi Nina – it really depends on the recipe. For this cookie recipe, there really is not adequate substitute for the butter. I like to use coconut oil in my recipes because it is so much better for you than canola or vegetable oil. So that is an option for anytime you see veggie/canola oil in my recipes. With regards to yogurt, applesauce, etc – it would depend on the recipe. Here are all of my healthy recipes if you’d like to browse: http://sallysbakingaddiction.com/category/healthy-recipes/

    THANKS! I will be addicted to this recipe forever. I’ve been having my sweet tooth satisfied by Blue Bell Vanilla Ice Cream and gooey mush of my own creation but this shames my recipe. I was simply trying to make a dessert with fiber. I mixed brown sugar, granulated white sugar, oat meal, peanut butter (or preferably almond butter), Grape Nuts Cereal, skim milk and chocolate chips and heated in the microwave and served with Vanilla ice cream. Now I am going to have to play with your recipe to see if I can add extra fiber without ruining its taste. Great idea and recipe though. :)

      You could definitely add a few more oats (or even oat flour instead of all-purpose) to the cookie recipe to increase its fiber. I love blue bell ice cream! Haven’t had the vanilla in years. It’s so good though!

      Unfortunately the answer to that question is highly dependable upon the recipe. No, you cannot take “any” cookie dough and make it into a 2-3 serving cookie. You could make a cookie the size of a pizza I’m sure, or 4-5 giant cookies – but again that depends upon the recipe.
