Step 1

First, spray an 8 or 9" cake pan with cooking spray (or grease with extra butter).

Step 2

In a large microwave-safe bowl, first make the yellow layer: combine the marshmallows, butter and salt. Microwave on HIGH for 30 seconds, stirring until melted. If it's not smooth and melty, return it to the microwave for another 15 seconds. Then, whisk in the food coloring followed by the rice cereal. Stir until well-blended.

Step 3

Using your hands, press the yellow layer around the edges of the pan to make a ring. See photo for reference. You may butter your hands to make it easier. Try to pack it firmly against the edges of the pan.

Step 4

Using the same bowl, repeat the process for the orange layer.

Step 5

Using a clean bowl, make the white layer in the microwave, pressing it into the center of the pan.

Step 6

Allow everything to cool for at least 2 hours before slicing into triangles.
