Do you guys remember cosmic brownies?! They actually still make them, but I haven’t eaten one since the 90s! I used to LOVE these things, and those candy coated chocolate pieces on top were SO good. I recently found those same sprinkles used for cosmic brownies at the craft store and I knew I had to recreate some kind of cosmic brownie recipe, so today we’re showing you how to make cosmic brownie milkshakes!! I mean, come on guys, is this not bringing back some nostalgia from your lunchroom days? Ha! This milkshake is super easy to make, so get ready to get hooked and add cosmic brownies back into your lunchtime routine.
