Copycat Cosmic Brownies

These copycat Cosmic Brownies are moist, chewy, dark chocolatey perfection just like the ones at your grocery store.

Hi! I’m Marye, from Restless Chipotle, and it’s that time again — time for me to get to share something I’ve found on Pinterest!

The roughest thing about being a food writer is that people assume my family loves my cooking and in reality they’d rather have boxed mac and cheese. Yes, it’s true. Things like snack cakes are gold to them. I know that even as I sit here writing this my kids are at school, at lunch, trading something wonderful for a Cosmic Brownie.

OK.  Cosmic Brownies are good. They are chocolatey, chewy, and pretty. Plus, who can resist something called Cosmic Brownie? Not this Baby Boomer.

So, when I saw this Cosmic Brownie copycat on Averie Cooks I knew I was going to make it. I was going to make it to see if my kids thought it was as good as the real thing. I was going to make it and see if they kept their own lunches.

That was the great thing about homeschooling, by the way. You knew who your kids were trading lunches with — HA!

I made this pretty much as written but I added a layer of chocolate chips to the top of the batter before baking just to give it an extra chocolate kick. I also am not a patient person so I invariably start cutting the brownies and taking pictures before they’ve had a chance to cool. It’s why I’ll never be one of those really awesome food photographers that gets props from Saveur. These are just as messy and gooey as they look — you’re gonna love them.
