Copycat Cosmic Brownies

Copycat Cosmic Brownies: Thick, fudgy brownies smothered in silky smooth chocolate ganache, and topped with M&M candies.

 Copycat Cosmic Brownies

I always hear adults talking about how busy kids are today. From sports, to music lessons, and even karate it seems like they are always headed somewhere.

However, I don’t think this is a recent phenomena. Every Tuesday I had to rush from dance class, to soccer. This inevitably resulted in having to eat dinner in the car.

 Copycat Cosmic Brownies

My typical meal was a toaster pizza (an actual pizza made in the toaster). Oh how I miss those! I also usually grabbed either zebra cakes or cosmic brownies from the vending machine.

No matter how hard I try I can’t ever recreate that toaster pizza. But I can create an even more delicious version of Cosmic Brownies. My version is thick and ultra fudgy. They’re also made with m and ms instead of unidentified candy bits (unless you’re into that).

  6. When I find a copycat recipe I expect it to taste like what it’s copycating.

    This recipe is not it. Too cakey. Followed the recipe exactly.

    • Hi Shannah,
      I’m sorry that the recipe was not what you were expecting.

      In the future, you may want to try adding an extra egg yolk or 2 for a fudgier brownies. Thanks for your feedback! 🙂

  7. My son loves these! Seriously! I can not wait to surprise him with this home made recipe. Thanks!

  12. Was wondering if I could double this recipe, or make it twice and bake it in a jelly roll pan? And if I could would I need to adjust the baking time? Thanks.

    • Hi Jenny,
      Of course doubling won’t be a problem. I wouldn’t suggest a jelly roll pan as that will give you a really thin as opposed to thick brownie.

      If you double the recipe in 2 different pans baking time shouldn’t need to be adjusted. As long as a tooth pick inserted in the center comes out with a few crumbs and not brownie batter they are done. Hope this helps. Let me know how they turn out!

      • I’m going to preface my comment with two things:
        1. I realize I’m a bit late to the game but wanted to share if someone else stumbled across this recipe
        2. I have never had a cosmic brownie so my mods may not produce a TRUE cosmic brownie experience

        I double the brownie recipe and baked in a jelly roll pan for about 30 minutes (started at 25 then had to add a few minutes) and used just one batch of the frosting and topped with mini M&M’s and they. were. uh-may-zing. Rave reviews from everyone at the birthday party I made them for! Super fudgy and delicious, thanks for a great recipe!

  13. Oh my gosh! I’ve got to try this right away. So chocolatey and yummy!! I think you are making all your readers very hungry. 🙂 I have pinned this. Thank you for such a fantastic recipe!

  14. Whoah, this is my kind of dessert!! I’m such a chocaholic and these brownies look like my perfect dessert! Yum!

  17. Hi, I love this recipie , tried them out today and they were a hit!! All my kids loved them , will always be making them for sure!!!! Thanks

  18. Is there anything to substitute for the heavy cream?

    • Hey Jen,
      Ganache needs to be made with heavy cream no exceptions. That’s what gives it it’s rich flavor and texture!

  19. They look so yummy!!!! Will try it.

  20. Jenn from Calgary says:

    These were sooooo rich and chocolaty. I made them last night to bring to work for my coworkers, but now I’m considering not sharing. I didn’t change anything about the recipe either, and they turned out perfectly. Mine actually look exactly like your picture too – talk about easy!

    • Jenn,
      So glad you enjoyed them, thanks for letting me know! Don’t blame you for not wanting to share at all! 🙂

  21. These look perfect! Thanks for linking up with What’s Cookin’ Wednesday!
