Notes

  • This recipe uses a jelly roll pan.  If you don't have one, they come in super handy, and many (like this one) come with a plastic lid making for easy storage. 
  • I like to line my jelly roll pan with parchment paper. This makes it easier to remove the Royal Chocolate Marshmallow bars from the pan.  
  • Chopped pecans or walnuts work in this recipe.
  • The chocolate peanut butter layer gets a little soft when they sit out at room temperature.  Chill these before cutting, and if possible, store in the refrigerator. 
  • Love chocolate?  Try Chocolate Cake Mix Crinkle Cookies.
