Do you remember the first time you ever tried cosmic brownies? Most of us could probably share a story or two involving lunch box snack cakes. Some of my favorites were oatmeal pies and crunches. My oldest always loved the brownies. That ooey-gooey chew. The crunchy sprinkles. It would make his mouth water thinking about it until lunch time. Now you can make your own Copycat Cosmic Brownies right at home. Who says you need a bag lunch to enjoy them? They’re just as perfect for summer play days by the pool or sprinkler.

Don’t get me wrong, there is nothing wrong with the pre-packaged snack cakes.  They are just as delicious!  However, for those who are dealing with food allergies/sensitives, this homemade recipe makes it’s easy to substitute so the whole family can enjoy them!  This recipe is also versatile as you can use whatever sprinkles you prefer!  Customize them for a birthday party, special celebration, or just for the fact it’s a Monday!

This copycat cosmic brownie recipe is super easy to make and contains ingredients you probably already have in your pantry and fridge!  All you need is light brown sugar, sugar, flour, unsweetened cocoa powder, chocolate chips, vanilla, eggs, heavy whipping cream, unsalted butter and candy sprinkles!

I hope you enjoy making these with your family!  I think they will become a family favorite!

Then slowly incorporate the cocoa powder and the flour.

Pour the batter into the pan and lightly smooth and level the top of the mixture. Put the pan into the oven and bake for 25 – 30 minutes or until the toothpick comes out clean.

While the brownies are cooling, making the icing in a medium bowl.

To make the icing, microwave the chocolate chips and cream in a microwave safe bowl for 1 minute then whisk until smooth.  Pour the icing over the cooled brownies and slightly smooth.  Refrigerate for 15 – 20 minutes, then add the sprinkles. Place the pan back into the refrigerator until the icing has completely set.

Once the icing has set, remove the pan from the fridge and slice the Copycat Cosmic Brownies and serve them on your favorite dessert plates! Or just eat one or two from the pan!
