Buttered rum is the next old school drink on your list to master - 'cause why not? Mix up a treat to complement your new concoction. Cut a chocolate peanut butter brownie into bite-sized pieces. Then, place half the brownie bites into the bottom of a bowl, layering on butterscotch pudding and whipped topping. Repeat with another layer of each. Add pretzels and enjoy - while planning your next cocktail party.
