Prepare the brownie mix according to package directions. Bake until toothpick comes out nearly clean from the center but still slightly undercooked. Remove from oven and let cool for 15 minutes. When you are able to touch brownies comfortably, scoop brownies with a medium cookie scoop, roll tightly into a ball and place them onto a wax paper-lined baking sheet. Continue rolling until brownies are gone. Freeze brownies until very firm, a couple of hours or overnight. No worries if your brownie balls aren't perfect, once frozen reshape them. They are easier to handle when chilled.

Place chocolate chips over a double broiler (or heat in microwave until smooth) to melt, then stir in peanut butter until creamy smooth. Roll each frozen brownie ball into chocolate and place onto wax paper to dry. Enjoy room temperature or chilled.
