Evenly spread the oats onto the bottom of a baking sheet and toast at 325 degrees for around 10 minutes; stirring around halfway through baking time.

While the oats are toasting, prepare the sauce.  In a medium saucepan; melt the butter and add the brown sugar.  Cook on medium/high eat until the sugar dissolves into the butter.  Mix in the honey, molasses, vanilla and salt.  Remove from heat and allow to cool slightly.

After the butter mixture as cooled for a bit; stir in the oats until evenly coated.  Lightly stir in the graham cracker, marshmallows and chocolate chips; reserving around 1/3 of the chocolate chips and marshmallows for the top of the granola bars.

Coat the bottom of a 9 inch square baking pan with strips of parchment paper; allowing the ends to hang over the sides for easy removal.  

Add the oat mixture to the bottom of the baking pan and evenly spread the mixture.  Top with the extra marshmallows and chocolate chips.  Firmly press down the top with the back of a measuring cup.

Freeze for around 30 minutes until firm.  Cut into desired serving size.  Store in an airtight container for up to 10 days for best results.
