  5. Lightly press mixture evenly into pan using rubber spatula or butter your fingers to press into the pan.
  6. Allow bars to cool for 30 minutes before cutting into squares.

Notes

  • Don't pack the bars too firmly in the pan. This creates a hard bar that will be difficult to eat. 
  • Fresh marshmallows are key for perfect bars!
  • Work quickly. The marshmallow mixture becomes very stiff once it starts to cool off, so get everything mixed and into the bar in a timely manner!
