Measure out the ingredients and set aside in bowls
In a saucepan, melt the butter over low heat and add the marshmallows. Stir the marshmallow cream mixture for about a minute and a half.
Pour the cream into a bowl containing the rice Krispies and mix with a spatula ensuring all the Krispies are coated with the cream.
Gently transfer the mixture into the greased tray, spread, and press onto the tray. Add some chopped-up marshmallows and continue adding the last layer of the mixture.
Set aside the tray, and let the mixture rest for two hours to set firmly.
Move the set bar onto a chopping board; using a sharp knife or cookie cutter, cut out your desired shapes.
Notes
Ensure you give it enough time to set before cutting in into your desired shapes
