Orange Creamsicle Rice Krispies Treats With Orange Buttercream

For Treats: Lightly coat a 9 x 13 inch pan with butter, oil, or cooking spray. Set aside.

In a large bowl, combine the cereal and marshmallow bits (if using). Set aside.

In a large pan, melt the butter over medium-low heat. Add the marshmallows and stir constantly to melt them. When they are almost completely melted, stir in the orange zest.

As soon as the marshmallows are completely melted, remove from heat and stir in the cereal. Make sure to get it completely coated with the marshmallow mixture.

Press the mixture into the prepared pan, making sure it is spread evenly. Don't press it too firmly, or the treats may set up very hard.

Allow the treats to set up for at least 10 minutes and cut into small squares or circles. Allow the circles to continue setting up while you make the frosting.

For Frosting: In a large bowl or the bowl of a standing mixer, beat the butter for 3 minutes. Beat in the sugar until combined. Add 2 tablespoons heavy cream and whisk on high for 4 minutes, until light and fluffy. Stir in the zest, juice and food coloring.

Pipe a small amount of frosting on top of it, then, press another treat over the frosting. Add more frosting on top of this treat. Pipe a rosette of frosting on top and garnish with sprinkles or candies.
