Line an 8x8” pan with foil and spray with cooking spray. (This is for easy removal from the pan.)

Place the chocolate chips and shortening or oil in a large microwave safe bowl. Heat in 30 second increments, stirring after each, until the chocolate is melted and smooth. (About 1-2 minutes in an 1100W microwave.)

Stir in the Golden Grahams and marshmallows. Pour into prepared pan. Press to compact (this is a messy step!) Chill until set. Slice into squares.

These melt like candy, so I suggest keeping them in the refrigerator if you’re not eating them right away. They taste best after the sit at room temperature for a few minutes. Store in an airtight container; they’ll last about a week.
