In a large saucepan, melt butter.

Add in marshmallows and stir continuously until fully melted and mixed with the butter.

Remove from heat and fold in graham cracker crumbs, rice krispies, and chocolate chips.

Press evenly into a greased 9 x 13 in baking pan.

Spread marshmallow fluff over the top of the rice krispies treats and break up the Hershey bar and scatter the pieces over the top of the fluff.

Use a kitchen torch to toast the top of the fluff. Let set for 15 to 20 minutes before cutting.
