It’s the year 2015 and we can upgrade just about everything. From pimped out popcorn to anything but ordinary milkshakes, it seems like we can take anything to the next level, and it turns out brownies are no exception.

Brownies are timeless, always in season, and never go out of style, so these recipes are applicable anytime, anywhere. Make some for your little brother, your great aunt, and your Grandma Judy.

You can add peanut butter, make it into a cheesecake, or even toss it in the waffle iron — the sky is truly the limit.
