Step 1

Spray an 8 inch cake pan with non-stick cooking spray. Set aside. Have butter available to grease your hands and spatula as needed for pressing treats into pan.

Step 2

Form one ring at a time, starting with the yellow ring. Melt the marshmallows and butter for that ring in a microwave safe bowl. Gently melt by stopping and starting microwave at 15 second intervals. Stir to mix with greased spatula, then add food coloring till desired hue is reached. Stir in Rice Krispies.

Step 3

With greased hands and a greased spatula, pat yellow rice krispie treats around perimeter of pan to form about a 1 1/2 inch ring.

Step 4

Repeat with orange ring using same procedure (except using orange food coloring) and form a second 1 1/2 inch ring, leaving the middle open for the white center.

Step 5

Repeat with last batch of marshmallows and butter and press into the center of the pan.

Step 6

Let cool for at least 30 minutes, then flip out of pan onto cutting board. Cut into 8 wedges to resemble candy corn.
