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.

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 a cosmic brownie from the vending machine. It was then all washed down with a fruity drink from the Tropicana vending machine. Seriously what happened to those drinks, I need to know!

No matter how hard I try I can’t ever recreate that toaster pizza. I don’t even want to try! 🙂 But I did create an even more delicious version of Cosmic Brownies. My version is thick and super fudgy. They’re also made with m and ms instead of unidentified candy bits (unless you’re into that). Easy to make and even easier to recognize they are sure to be a crowd pleaser. They’re great for school lunches, potlucks, and  picnics. Wash them down with an ice cold glass of milk, or if you’re feeling especially decadent a scoop of vanilla bean ice cream.

What Is In Cosmic Brownies?

You only need a few ingredients to make these tasty treats. They include: Butter, Eggs, Sugar, Brown Sugar, Vanilla, Cocoa Powder, Flour, Semi-sweet Chocolate Chips ,and Heavy Cream.

Cosmic Brownies Recipe

Cosmic Brownies are a rich chocolate brownie, with a layer of chocolate icing, and a sprinkle of chocolate candies on top.Start by preheating your oven to 350.

Then, mix together ¾ cup melted butter, 2 eggs, 1 cup sugar, 2/3 cup brown sugar, and 2 teaspoons of vanilla in a large bowl. Whisk in ¾ cup cocoa powder and ¾ cup flour until combined.

After that,pour the batter into a lined 9 in. by 9 in. pan and smooth the top until level. Bake 25 – 30 minutes. To tell if 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.

How to Make Cosmic Brownie Icing

Now time for my favorite part: the frosting! While your brownies are cooling, you can make the chocolate icing that will go on top of your brownies.
Start by microwaving 1 ½ cups of semi-sweet chocolate chips with ½ cup of heavy cream until melted. Whisk together until smooth, then pour over your cooled brownies.

I also like to add rainbow M&Ms or candies for an authentic look. To stay true to classic cosmic brownies, you should cut them in rectangles, with an indent going through the halfway point. This was in the original design so you could split the brownie and share it. Yay sharing! 🙂

When Did Cosmic Brownies Come Out?

Cosmic Brownies were created in 1957 by the Little Debbie Snack Company. Want to hear a secret? The same fudge brownie recipe is used in both Little Debbie Cosmic Brownies and the classic Little Debbie Brownies.  The only difference is the classic version has a walnut topping.  Mind blown! I’m not a big fan of nuts in my desserts, so I’ll stick with the cosmic variety.

How Long Do Brownies Last?

 Brownies last for three or four days when kept at room temperature.  Be sure to keep them in an air tight container so they do not dry out. You can use a tupperware dish, or a pan tightly wrapped with aluminum foil. Just be sure to close if tightly after going back for seconds thirds!

Can You Freeze Brownies?

Also, you can always freeze your brownies to make them last longer too. Tightly wrapped brownies can be frozen for up to three months. When you want to enjoy your frozen brownies simply thaw at room temperature for 2-3 hours. Perfect for that gotta have it NOW chocolate craving.

How to Cut Brownies

I like to bake my brownies in a pan lined with foil. To cut them I lift out the foil and brownies onto a hard surface. Be sure brownies are fully cooled before attempting to cut them. Mom Hack: My mom taught me to always cut my brownies with a plastic knife and I still use that trick today!  Huh maybe she did know a thing or two. Plastic knives are naturally non stick. Also, be sure to wipe down the knife after each cut.
