1-Spray or grease an 8 or 9-inch cake pan to prepare it for the layers.

2-For the Yellow Layer: In a microwave-safe bowl, melt 2 1/2 cups mini marshmallows, 2 tablespoons butter, and a big pinch of salt on high for about 30 seconds, or until smooth. Stir in 5 drops yellow food gel and 2 1/4 cups crisp rice cereal until combined, then press the mixture around the edges of the pan to form a ring.

3-For the Orange Layer: Using the same bowl without washing it, melt 1 3/4 cups mini marshmallows, 2 tablespoons butter, and a big pinch of salt on high until smooth. Stir in 5 drops yellow food gel and 1-2 drops red food gel for the perfect orange shade, then mix in 1 1/4 cups plus 2 tablespoons crisp rice cereal. Press this firmly inside the yellow ring in the pan.

4-For the White Layer: In a clean microwave-safe bowl, melt 3/4 cup mini marshmallows, 1 tablespoon butter, and a big pinch of salt on high until smooth. Stir in 3/4 cup crisp rice cereal until combined, then press it into the center of the pan, filling the space inside the orange layer.

5-Let the layered treat cool completely in the pan for at least 2 hours so it sets properly.

6-Once cooled, remove from the pan and slice into wedge-shaped pieces to make them resemble candy corn.
