Fun Flavor Twists

Enjoy this recipe as written below. Or try these easy upgrades:

  • Graham it up. Give it traditional graham flavor by swapping out the pretzels for an equal amount of graham animal cookies.
  • Brownie A La Mode. Break out a gallon of vanilla ice cream and top each serving with a scoop.
  • Candy Bar Lottery. We’re partial to PB cups, but sub in your favorite candy bar to customize. Snickers, Twix, Rolos – you decide!
