For Halloween week, Crumbl released their fan-favorite Monster cookies for the week. The number of requests I received to remake them were crazy so I had to do it ASAP! I used a mixture of brown and granulated imperial sugar to get that chewy texture from Crumbl and trust me when I say this, we succeeded!
This is the best Halloween Crumbl Monster cookie recipe ever!
This recipe couldn’t have been released at a more perfect time too! I feel like a lot of us are going to have extra leftover candy from Halloween so what more of a reason to make these cookies.
Plus you can always mix and match, so instead of using chocolate chips, you can go with chopped-up Twix or Reese’s cups… or whatever the heart desires really!

Usually, monster cookies do have oats in them but this time since I am working off of an already existing recipe that doesn’t include them I didn’t add them either.

Frequently asked questions – FAQ
How to store Monster cookies?
You can store them by placing them in an airtight container and storing them at room temperate for up to 4 days.
You can also store them in an airtight container in the fridge for up to 7 days. I prefer this method and usually pop them in the microwave for a few seconds to get them soft and chewy, ooey-gooey again!
HOW CAN I MAKE CRUMBL CATERING SIZED COOKIES?
Instead of making 8 giant cookies, you can make 16 smaller catering size cookies by dividing your cookie dough into 18 little balls and baking them in the preheated oven for 9-10 minutes.

I haven’t made these yet. The reviews are great. The only thing that is keeping me from making them is the original Crumble monster cookie has oatmeal in them. I wanted to recreate those since my son loved the ones in the shop. I have made the Cornbread and the Circus Cookie so far and they are excellent. Thank you so much!!
Glad to hear you enjoyed the other recipes you tried Cheryl!
Thank you for the kind words!
Ok so I turned this into a cookie and and ๐๐๐๐these are amazing my only issue was that I didn’t know what you meant by 2 and 1 cups ….. is that 3 orrrr… yeah so the batter was a bit taker than that grainy dough I’m used too which prompt Ed d me to make the cake instead but it was amazing never the less
Oh no! What part were you confused on?
Chahinez is a genius. I have been making monster cookies for 6 years now, specifically when we set up Christmas. My husband said to never mess with or change this recipe as it was the best one he has ever had! I have made 7 of the cookies at this point and all have been ๐ฅ. Literally no fail because of you, Chahinez! I donโt even know you, but your recipes, blog and Instagram make me feel like Iโm cooking with a friend!
oh my goodness! This is the kindest comment ever! Thank you so much for trusting me with your baking and supporting what I do! You make all of this possible ๐ THANK YOU!!

Chahinez

So happy to hear that!

We donโt have a Crumbl nearby, so I didnโt realize the monster cookies had two kinds of chips plus the m&m candy. I canโt wait to try these once I get all of the ingredients together. Your cookie looks so tempting and since I have tried many of your other cookie recipes and all are 5-stars, I am sure these too will be nothing short of amazing!
I sat out a stick of butter this morning to make cookies, itโs like you knew, and posted this recipe! These were some of the softest cookies Iโve ever made. I dug into my daughterโs Halloween candy and used that instead of the chips and m&mโs. We made ice cream cookie sandwiches. My husband said theyโre better than Crumbl.
OMG! That’s amazing Chelsea!! I am so happy that I shared this recipe at the right time. Can’t wait for you to bake more of my cookie recipes ๐
