Chocolate brownies with confetti sprinkles

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!
