Coat a 9x13 baking dish with cooking spray. Set aside
Place cereal in a large bowl. Add the chocolate chips.
Remove 3 cups of mini marshmallows from bag. Toss with the cereal and chocolate chips. Set aside the other 1/2 cup marshmallows to press onto bars later
In a pot, melt the butter over medium-low heat. Add the remaining marshmallows. Stir constantly until just barely melted. Remove from heat. Let cool for 2 minutes.
Pour the melted marshmallows over the cereal mixture. Stir until evenly coated. Pour into the prepared pan and flatten with a greased spatula or rolling pin.
Separate the herseys bar into squares and then cut them in half so they are in 4th.
Press the chocolate squares and the rest of the marshmallows into the top of the Rice Krispies.
Cool completely and then just cut them however you’d like. I did little balls so my kids could just grab them and eat! You could also do squares!
OPTIONAL** add caramel drizzle over the top.
