Make Ahead: Covered tightly with aluminum foil or plastic wrap, these will keep on the counter for up to 3 days. To reheat, just place in the microwave for 15 seconds to make them gooey and warm.
Variations: You can swap out the chocolate chips for a variety of other toppings to change up these bars. Here are some of our favorite combinations:
o Crushed Andes pieces or Peppermint pieces
o Candy Mix-in's: Toffee bits, candy canes, Oreos
o Add any of your favorite chips: Semi-sweet-, dark, white, butterscotch, cinnamon chips.
