Start by toasting 1 cup of mini marshmallows briefly under the broiler on a pan lined with parchment paper. Allow the toasted marshmallows to cool and set about 1/4 cup aside for garnish.
Chop the Hershey’s milk chocolate bars into small pieces. Set a couple of tablespoons aside for garnish.
Melt the butter in the microwave for about 30 seconds. Add 3 cups of mini marshmallows and stir to coat them with the melted butter.
Return to the microwave for 45 seconds, and stir until smooth. If necessary, return it to the microwave for 10-15 seconds longer.
Stir in the Rice Krispies cereal until well coated.
Mix in the mini toasted marshmallows, chopped Hershey's bars, and 3/4 cup of mini Teddy Grahams.
Press the mixture into a greased 9-inch square pan. Garnish with the toasted marshmallows, chopped chocolate bars that were set aside, and the remaining 1/4 cup of mini Teddy Grahams.
Allow the bars to cool before cutting them into squares.
