This is how you make gooey, chewy, massive rainbow cookies that make everyone in life love your guts.

Giant Rainbow Cookies I

Lookie here! You don’t even need a mixer. You just mix all the goods with a whisk. Don’t have a whisk? Spoons work too.

Add some super cute rainbow candies… aka mini m&m’s. You could add regular m&m’s. Really… whatever floats your boat.

This is the weird part. Roll your dough into a ball then rip it apart evenly with Hulk Hogan strength.

Giant Rainbow Cookies I

Bake cookies like this. Laugh because they look funny. Cry because you are ridiculous.

Giant Rainbow Cookies I

Not even joking. Really bake your cookies like this. It’s the SECRET.


While your cookies are baking, admire the adorable slash colorful slash overflowing bowl of mini m&m’s that you opened two bags of m&m’s for just so you could show all of your invisible internet friends what an m&m bathtub looks like.

After your cookies bake and cool and you inevitably burn the skin off the roof of your mouth because you’re really a child with no patience, flip it over and look at how pretty it’s cookie butt is. Colorful cookie butt.

Giant Rainbow Cookies I

Stack up some giant rainbow cookies and set them by your overflowing m&m bathtub bowl. Pour a mason jar full of milk so you can photograph your cookies for your invisible internet friends, even though you hate milk and don’t even like to dip cookies in it.

Giant Rainbow Cookies I

Talk to your cookies because they are so pretty and perfect.


This recipe was sent to me by a reader, Gabrielle (Hi Gabrielle!), and as soon as it hit my inbox I knew I had to make them. I can easily say this is the best cookie I have ever made and that is no exaggeration. Ask Gabrielle… because I professed my love for her immediately like a complete weirdo.

Up until now, I have been using my fat snickerdoodle recipe… which took me hours upon hours to perfect, as the base for newer cookie recipes like my blueberry cookies and chocolate chip oatmeal cookies. I can say with almost 100% certainty that this will be the only cookie recipe I use for the time being… because if you can’t tell, I’m infatuated. With a cookie. Haaaalp me.

Giant Rainbow Cookies I

Giant Rainbow Cookies

makes 18 large or 36 small cookies

2 cups + 2 tablespoons all-purpose flour

1/2 teaspoons baking soda

1 1/2 sticks (12 tablespoons) of salted butter, melted and cooled

1 cup brown sugar

1/2 cup sugar

1 egg + 1 egg yolk, at room temperature

2 teaspoons vanilla extract

1 cup mini m&m’s (or something else that you love)

Preheat oven to 325 degrees F.

Mix the flour and baking soda in a bowl and set aside. In another bowl, mix the butter and sugars until they are combined (and look like the first picture above). Add the egg, egg yolk, and vanilla and stir until mixed. Gradually add flour and mix until a dough forms – it will look crumbly at first, but it will come together. I even used my hands to help at one point. Fold in the m&m’s.

Divide the dough how you choose (1/4 cup portions for 18 large cookies or 2 tablespoon portions for 36 smaller cookies). Shape each portion into a ball with your hands then pull each ball into two equal pieces. Turn each half so that the rough side of the half (what used to be the inside of the ball) faces upwards and then squish both halves together. Place the dough rough-side up on a baking sheets. If you’re doing large cookies, I’d leave about 2 inches in between each.

Bake for 12-15 minutes (large cookies) or 8-12 minutes (small cookies) or until the edges are slightly brown. The centers should be
soft and puffy. Do not over bake. Let cool completely then dig in!

Note: to melt the butter I simply microwaved it, and to let it cool I allowed it to sit for about 10 minutes.

ETA: a few readers have told me that this is the same recipe as Cooks Illustrated chocolate chip cookie recipe!

Giant Rainbow Cookies I

Finally, take one single bite of your cookie since you are the epitome of self control, then neatly pack them up to share with others. Do not eat any more cookies, ever, because you are always satisfied with one bite of dessert.

    These remind me of the delicious Mrs. Fields cookies that I would always get as a child–Now I’m just going to have to make them from scratch as an adult ;)


    • Jessica — July 13th, 2011 @ 7:11 am

      My brother actually SAID that they tasted like the Mrs. Fields cookies. I am telling you – they are amazing!


      • Brittany @ Itty Bits of Balance — July 13th, 2011 @ 7:25 am

        Great minds think alike! ;)
        Maybe I’ll be making these for lunch & dinner tonight… just sayin’…

    mmmmm….big fat cookies with M&M’s in them. My 5 year old is yelling at me… “Make Those”…as she is looking at your pics!

    Vicky @ Recipe Adaptors — July 13, 2011 @ 7:17 am

    Are you trying to steal my husband? He could eat that whole batch of cookies in 5 seconds. And that would be him eating cookies at a leisurely pace.

    hahahaha cookie butt!

    Holly — July 13, 2011 @ 7:22 am

    I’ve never even thought to bake cookies like that- the double stack. Sounds like it really is the secret to these delicious looking cookies!! :) I would just have to figure out how to keep my husband away from the m&m’s :)

    Kathryn — July 13, 2011 @ 7:26 am

    Those look like the absolute perfect cookie not to mention the giant bowl of M&Ms…swoon!

    Julie H. — July 13, 2011 @ 7:27 am

    THANK YOU for the stacking tip!!!!! I’m pretty sure it just changed my life!!!! :)

    Hayley @ Hayley Daily — July 13, 2011 @ 7:28 am

    Those look so perfect. How can something so simple be so amazingly perfect??

    I won’t lie, I had to snicker (ha, snicker) at the ‘makes 18 large or 36 small cookies.’ WHO MAKES SMALL COOKIES?? I would really like to meet that person at some point in my life.


    • Jessica — July 13th, 2011 @ 7:53 am



    • Kelly — July 13th, 2011 @ 8:15 am

      I make small cookies so I can have more :D

    Chrissy — July 13, 2011 @ 7:28 am

    I should make these for my boyfriend. He loves M&Ms. I wonder if using pretzel M&Ms in cookies would be good? I made sweet and salty chocolate chip cookies for Christmas with potato chips and pretzels in them and everyone went nuts.


    • Jessica — July 13th, 2011 @ 7:53 am

      Definitely. I think putting ANYTHING inside these cookies would be amazing.


    • Ashley — July 13th, 2011 @ 8:26 am

      I make cookies with pretzel M&Ms! The cookies have to be made really big though because the pretzal M&Ms are pretty huge:)

    Lisa {Smart Food and Fit} — July 13, 2011 @ 7:28 am

    These look like fun! I make mine with oatmeal, peanut butter and m&m’s! But I bet my kids could take a break from oatmeal cookies and go for these sinful cookies instead!


  12. #
    Heather (Heather's Dish) — July 13, 2011 @ 7:32 am

    these were the ONLY cookies i would get at the mall growing up…if they didn’t have color, i didn’t want them! totally making these immediately…well, like tonight :)

    Erica — July 13, 2011 @ 7:36 am

    What a pretty cookie! The whole tear it apart and bake it stacked trick- I have definitely never heard of that one. But the result is perfect!Hooray for cookies! I love your cookie recipes.

    Blog is the New Black — July 13, 2011 @ 7:36 am

    Love the idea of the double stack to make ’em nice and flat!

    Maggie @ A Bitchin' Kitchen — July 13, 2011 @ 7:37 am

    I think I’ve made this recipe before, but as regular chocolate chip cookies! Delish!

    Can I ask where you managed to find mini M&Ms? I haven’t been able to find them in my grocery stores for over a year (except for the ones in little tubes…not a bag)


    • Jessica — July 13th, 2011 @ 7:51 am

      I actually found them right in the candy aisle of my grocery store! I had no intention of using them and was just going to get the regular ones, but then I spied these. They were expensive though – nearly $5 for a bag!

    Cassie (Bake Your Day) — July 13, 2011 @ 7:43 am

    If nothing else, they are adorable but by your explanation, I’m sure they taste fabulous and I love that they are easy to mix by hand! I don’t like milk either and most people think I’m crazy!


    • Jessica — July 13th, 2011 @ 7:51 am

      I’ve never liked it! That’s why I always use vanilla almond or vanilla coconut milk because the vanilla makes it so much better!

    Aimee @ShugarySweets — July 13, 2011 @ 7:46 am

    These look great, I’m going to have to try them!

    Liv @ The Salty n' Sweet — July 13, 2011 @ 7:56 am

    Wooo! Party in the M&M bathtub!!!!!

    And I must say, that is one perfect cookie butt :) Thanks for the recipe Gabrielle and Jessica, though I’ve always wondered what the extra two tablespoons of flour do in a recipe.


    • Jessica — July 13th, 2011 @ 8:10 am

      Ha – I honestly have no idea!


  24. #
    Angela @ Eat Spin Run Repeat — July 13, 2011 @ 7:59 am

    Oooh yum these SO remind me of being a kid! PS. if you like m&ms, you should make this cake:


    • Jessica — July 13th, 2011 @ 8:10 am

      I pinned that too – it’s SO cute!

    Kim in MD — July 13, 2011 @ 8:04 am

    Cookie butt? You are so funny, Jessica! :-)

    This dough is the Cook’s Illustrated Thick and Chewy Chocolate Chip Cookie recipe, with the chocolate chips replaced with mini M&M’s. I have been making this recipe for years-it is absolutely my favorite chocolate chip cookie recipe! Seriously, I was always hunting for “the best” chocolate chip cookie recipe until I tried this one. It is THE. BEST. EVER. I love that you replaced the chocolate chips with mini M&M’s, Jessica. It’s kind of like sprinkles in your cookies! ;-)


    • Jessica — July 13th, 2011 @ 8:10 am

      Thanks Kim! I was just asking someone on Facebook if they knew where the recipe originated from. I’m gonna link it now!


  26. #
    Jess — July 13, 2011 @ 8:09 am

    An acquaintance of mine made a similar cookie for a 4th of July party, but she slathered vanilla icing in between two cookies. They made a scrumptious, irresistible cookie sandwich!


  27. #
    Brooke @ Bittersweetb — July 13, 2011 @ 8:10 am

    Those look so soft and chewy! Yum. I’ve never seen cookies stacked like that before but now I definitely want to try it.

    Kelly — July 13, 2011 @ 8:18 am

    Jessica! Now I have to buy Mini M&Ms or Mini PB Cups….or both!!!! Altho, the boyfriend would like pretzel M&Ms in his, that’ll have to wait till he buys M&Ms!


  32. #
    Lisa @ Sunny Seed Stories — July 13, 2011 @ 8:22 am

    GREAT idea stacking the cookies! I’m assuming the center is even more gooey as a result?


  33. #
    Robyn — July 13, 2011 @ 8:25 am

    Oh how fun!


  34. #
    Lynne @ 365 Days of Baking — July 13, 2011 @ 8:30 am

    The cookie sounds amazing – will definitely have to try it. Love M&M’s, but I’m with you, no milk.


  35. #
    Jihane @Sinful Sundays — July 13, 2011 @ 8:33 am

  36. #
    shannon — July 13, 2011 @ 8:35 am
