Best Copycat Little Debbie Cosmic Brownies

This homemade Copycat Little Debbie Cosmic Brownies retro recipe is reminiscent of those individually wrapped lunchbox treats, but this version tastes less artificial because they are made without hydrogenated oils or processed ingredients you can’t pronounce. Baking brownies from scratch is so much better than anything store-bought, plus it’s a fun way to recreate a favorite childhood snack filled with all the fudgy flavors!

These Copycat Cosmic Brownies are ultra chewy and rich and covered with a chocolate frosting that’s topped with colorful candies. This easy-to-make recipe will never go out of style; with servings for 12 and no cellophane to unwrap, it’s an “out of this world” snack that’s special enough to share.

  • Custom Colors: Feel free to decorate your brownies with custom colors for holidays or any celebration. Use red and green candy for Christmas, orange and black for Halloween, red, white, and blue for July 4th, and pastel colors for Easter. You can even use your favorite sports team colors for game day gatherings.
  • Colored Candy: Instead of M&Ms, you can top your brownies with any colorful candy. Some other ideas include rainbow sprinkles, chocolate-covered sunflower seeds, and rainbow crunch chips.

How to Make Copycat Little Debbie Cosmic Brownies

Copycat Cosmic Brownies look just like the Little Debbie lunchbox treat, but taste even better! This fun retro recipe takes mere minutes to prepare and bakes into the best bite of a rich and fudgy base with a smooth chocolate coating and topped with colorful candy.

  1. Melt: Melt the butter and one cup of chocolate chips on high for one minute. Remove from the microwave, stir, and continue microwaving in 30-second increments until just a few chips remain unmelted. When you do the final stir those last few chips will melt.
  2. Mix: Add the sugar, then the eggs, and whisk to combine. Wisk in the flour, cocoa powder, salt and milk until well combined. Stir in the remaining chocolate chips.
  3. Bake: Pour the brownie mixture into the prepared pan and bake at 350 degrees Fahrenheit for 22-25 minutes.
  4. Cool: Cool completely before frosting the brownies.
  5. Frost: Frost with chocolate icing and sprinkle with mini M&Ms.
    Pro Tip: If your frosting is a little stiff to spread, microwave for 10 seconds.
  6. Serve: Slice, serve and enjoy!

Tips

  • Don’t overmix your batter or you will have tough dense brownies. Mix until the flour is just combined for moist brownies with a tender crumb.
  • I like to line my pan with parchment paper or foil for easy cutting and cleanup.

Storage Tips

  • To Store: You can store these brownies in the fridge in an air-tight container for up to 5 days.
  • To Freeze: Freeze these copycat cosmic brownies for up to 3 months in a freezer-safe container. When you’re ready to eat them, thaw them overnight in the refrigerator.

Frequently Asked Questions

Can I freeze my brownies?

Yes, you can absolutely freeze these brownies! The fudgy texture and soft frosting actually makes these so good out of the freezer (they’re not rock hard!).
If you want to prevent the frosting from smudging, freeze the brownies unwrapped and uncovered for 1-2 hours, and then transfer them to a freezer-safe container. This will allow the frosting to freeze so that it remains pretty when you store the brownies.

How can I tell if my brownies are done baking?

To tell if your brownies are done, insert a toothpick in the center. If the toothpick comes out with a few crumbs, your brownies are done. If you still see batter on the toothpick, bake for 2-3 more minutes at a time.

What is the best way to slice my brownies?

If you want the classic cosmic brownie look, you should cut them in rectangles, with an indent going through the halfway point. This was in the original design so that brownies could be split and shared.
