Spray a 9x13 pan with a non-stick coating spray and set aside.

In a large pan, melt the butter over low heat.

Add the marshmallows and stir constantly until melted.

Remove from heat and stir in the cereal until evenly coated.

Transfer the cereal mixture to your prepared pan and press down firmly to even out.

Cool for 30 minutes.

In a microwave safe bowl, microwave the solid shortening for 45 seconds. Add the Wilton candy corn melts and stir until completely melted and smooth. (Depending on the wattage of your microwave, you may have to microwave in additional 10 second increments until melted).

Using a spatula, spread a thin layer of the melted candy corn chocolate on top of the Rice Krispies treats.

Before the candy corn chocolate hardens, sprinkle candy corn on top and place in refrigerator for 10 minutes to allow the chocolate to harden quickly.

In a microwave safe bowl, melt the orange chocolate melts in 20 second increments until completely melted. Using a spoon, drizzle the melted orange chocolate on top of the candy corn treats.

In a microwave safe bowl, melt the yellow chocolate melts in 20 second increments until completely melted. Using a spoon, drizzle the melted yellow chocolate on top of the candy corn treats.

Cut into even squares and ENJOY!
