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 White chocolate chips + butterscotch chips
o M&M’s (we love to use colored M&M’s for the different holidays!)
o Chocolate chips + toffee bits or peanut butter chips
