Fat and Weird Copycat Cookie

I have made tens of thousands of cookies in my life! Every kind of cookie, Brown Sugar Poptart cookies, Orange Creamsicle cookies. When it comes to unique cookie recipes, I am your source! So when Brad from Fat and Weird Cookies reached out to me, I knew I had to try their cookies and make a copycat.

Fat and Weird cookies have absolutely HUGE 1 pound cookies. But it isn’t just their size that makes them different from the pack! Fat and Weird lives up to their name with super wacky but somehow perfect cookie flavors. Like this Dirty Worm cookie! A brown sugar cookie Cookies and Cream cookie, stuffed with white chocolate chips, Oreo pieces and filled with a cookies and cream frosting and a gummy worm randomly stuffed in there, and topped with teal sprinkles…because everything is better with some sparkle!

Ingredients for Dirty Worm Cookies

For the Cookies

  • Butter– I always use salted butter, if you only have unsalted on hand you’ll want to add an extra pinch of salt to your cookie dough.
  • Brown Sugar– This cookie is mostly a brown sugar base, which gives the cookies a wonderful flavor and a soft, chewy texture.
  • Sugar
  • Egg
  • Vanilla– I love to use either Lorann Oils or Watkins brand of Vanilla. This will be the main flavor of our cookie dough.
  • Flour- Just plain old all purpose flour will do the trick for these cookies.
  • Baking Powder– We use Baking powder instead of baking soda in these cookies because we want the cookie to have a lighter crumb that isn’t super dense.
  • Salt
  • Oreos- Chopped up into small pieces- just roughly chop each Oreo into 6-8 pieces.
  • White Chocolate Chips

For the Cookies and Cream Filling

  • Butter– Again, salted butter is what I use.
  • Shortening- The combination of shortening and butter allows for you to stuff the cookies and bake them without the filling turning to liquid.
  • Powdered Sugar– this will thicken the filling, making it a frosting consistency.
  • Oreos- Make sure they are finely chopped.
  • Vanilla
  • Heavy Cream– just a tad, so we can make sure the feeling is both creamy but also very thick.
  • Gummy Worms– Fat & Weird cookies puts one gummy worm into each cookies and cream filling so we will do the same.
  • Teal Sprinkles– Okay, you could really use any color of sprinkles but I used teal because I had to make this look as close to the real deal as possible!

How to Make Dirty Worm Cookies

This recipe will make two 1lb cookies.

  1. Start by making the Cookies and Cream core, we will start here so that it has time to solidify in the freezer before we put it inside of the cookie and bake it.
  2. Cream together the butter and shortening until smooth and well combined with either a stand mixer or electric hand mixer.
  3. Add the vanilla, powdered sugar and heavy cream and continue to mix until everything is thick and creamy.
  4. Fold in the finely chopped Oreos, don’t over mix or else your core will just be grey with no specks of black Oreo.
  5. Divide the frosting into four equal parts. Place a gummy worm on the top of two portions and then stack the remaining portions on top, leaving you with two cookies and cream cores.
  6. Place the frosting cores into the freezer until needed.
  7. To make the cookie dough, cream together the butter and sugar until light and fluffy. Scrape the sides of the bowl.
  8. Add the eggs and vanilla extract and beat again until it is mixed well.  
  9. Scrape the sides again and add the flour, baking powder and salt. Mix again until just combined.
  10. Add in the chopped Oreos and white chocolate chips and mix until the cookie dough forms. Split the dough into equal parts.
  11. Take one part of the cookie dough and flatten it out.
  12. Place a frozen mound of Cookies and Cream frosting on the flattened piece of dough and wrap the dough up around the filling. Repeat with the second dough ball.
  13. Dip and press the top of the unbaked cookie into teal sprinkles and place it on a prepared cookie sheet.
  14. Return the cookie dough to the freezer while the oven preheats.
  15. Preheat the oven to 350° F.
  16. Once the oven has reached temperature, pull the cookies out of the freezer and bake for 20-22 minutes.
  17. The cookie should keep the same shape pretty well, the bottom will expand just slightly, but the final cookie should look extremely round, fat & weird. 🙂
  18. Allow the cookie to cool on the pan for 30 minutes before cutting and serving.

How to Store Fat & Weird Cookies

This homemade version will store at room temperature for up to 3 days. If you’d like to store it longer than that, I would suggest freezing the cookie once it has baked and then completely cooled. It can be stored in the freezer for up to 3 months.

How to reheat Fat & Weird Cookies

My favorite way to reheat my giant cookies from either room temperature or frozen is to toss them into a 350° F oven for 5-7 minutes. You’ll be surprised, the taste like they were just made!

    Karli, I don’t know how you always do it, but these came out INCREDIBLE. I doubled the recipe to make 4 monstrous cookies and I skipped the worm because I’m not a fan of gummy candy in baked goods. These came together perfectly and I am in love with the chewy cookie base and delicious buttercream inner. I hope more people give this a try and hope to see more similar to this in the future!!
