Brownie-and-Peanut-Butter Ice Cream Sandwiches
If a rimmed baking sheet doesn't fit in your freezer, cut the brownies in half crosswise. Place one brownie in a 9-by-13-inch pan, cover with half of the ice cream, and top with another brownie. Cover and freeze. Repeat with remaining brownies and ice cream. Use your favorite brand of conventional peanut butter here; the flavor and texture of all-natural versions do not work well in this recipe.
