Spray a pie pan with a non-stick cooking spray.

In a mixing bowl, place 2 cups of the Rice Krispie Cereal.

Then melt approximately 1/3 of the bag of marshmallows with 1 Tablespoon of butter in the microwave in a microwave safe.

Stir this mixture into the mixing bowl with the 2 cups of rice krispie cereal. Stir until the ingredients are thoroughly combined.

Press this rice krispie treat mixture firmly into the bottom of the pie pan. Just line the bottom of the pie pan and make it thicker around the outside of the pan for the crust of the pie.

Then place the remaining rice krispie cereal in a large mixing bowl.

Then melt the remaining butter and marshmallows in a microwave safe dish. Add in the orange food coloring and stir until it's a bright orange color.

Stir in the orange marshmallow mixture into the mixing bowl with the remaining rice krispie cereal and stir until thoroughly combined.

Add the orange rice Krispies treats into the pie pan on top of the non-colored rice krispie treats. Press them down.

Allow them to cool at room temperature for at least 30 minutes- 1 hour (do not refrigerate).

Cut like a pie and top each piece with whipped cream before serving!
