Brownie Brittle from Sheila G's comes in a variety of flavors, including Chocolate Chip, Salted Caramel, and Meyer Lemon. The company has teamed up with Hershey's to bring us a Reese's Pieces-inspired collection. Brownie brittle, on the other hand, is thin and crunchy, unlike conventional brownies, which are rich, mushy, and cake-like. It's the same concept as peanut brittle, except it's kinder to your teeth. When you combine brownie brittle and Reese's Pieces, you get an even more decadent delicacy that's difficult to refuse.
