Tips from the Betty Crocker Kitchens

  • tip 1
    A layer of parchment paper on the bottom of your pan is a great way to keep these bars looking great. It makes removing your bars from the pan super simple, and clean up is even easier!
  • tip 2
    Love chocolate? Try swapping the peanut butter for hazelnut spread with cocoa. Delicious!
