Place marshmallows and butter into a large heat proof bowl. Microwave until melted and puffed up, about 1 minute 30 seconds (will be different in all microwaves, watch through the glass.) Remove bowl and add Hershey’s Simply 5 Syrup and cereal. Stir to combine then gently stir in chocolate chips. Transfer to a parchment lined 9 x 13 inch baking dish, pressing evenly. Let cool completely before cutting into squares. Serve room temperature.
Notes
Have all of your ingredients measured out in advance.
Grease your mixing spoon so ingredients don't stick while stirring. This is a lifesaver.
Once your marshmallows have been combined with the cereal mixture, work quick to transfer to baking sheet. When marshmallows set up, it gets more difficult to stir and transfer.
