In a large saucepan combine the marshmallows and butter and stir over medium heat until the ingredients have melted, stirring consistently.
Add a 4-5 drops of orange food coloring (or more depending on the desired color) to the pot and stir until it has been fully incorporated.
Add in your rice Krispies while continuing to stir the marshmallows and butter. Continue to stir until the rice Krispies are completely coated.
Allow the rice Krispies to cool slightly and spray your hands with nonstick cooking spray. Split the mixture into 6 equal sections and roll each one into a sphere and place them on a sheet pan.
Place one pretzel in the middle of each sphere to give the appearance of a stem and use the decorative frosting to create a vine on each sphere.
Allow to cool completely, serve, and enjoy!
Notes
Use medium-low heat to melt the marshmallows and butter. If the burner is set too high, they can easily burn.
Stir the orange food coloring into the melted butter/marshmallow mixture before adding the cereal.
Buttering your hands helps prevent the Rice Krispies mixture from sticking to you.
Storing and FreezingStore Rice Krispie treats in an airtight container at room temperature for up to 3 days.To help keep the treats chewy, place a slice of bread in the container.
