Found the recipe on Something Swanky.
6 cups white chocolate chips (I used the Nestle Toll House ones)
2 cans sweetened condensed milk
food coloring : yellow & orange
How to make it:
Line a 9x9 baking dish with wax paper
In a large saucepan, combine the white chips and sweetened condensed milk over medium-low heat.
Stir until completely melted and smooth, remove from heat
Pour 1/3 of the mixture into prepared baking dish and chill for 15 minutes
(Keep remaining fudge in sauce pan, heat off)
Stir fudge over low heat until melted and smooth again (should only take a minute or two)
Pour 1/3 mixture into a medium bowl and whisk in some orange food coloring.
Pour over the chilled white layer in baking dish and chill for 15 minutes.
Again, reheat the remaining 1/3 fudge over low heat until melted and smooth.
Whisk in yellow food coloring, pour over orange layer in baking dish.
Let chill for 3-4 hours or overnight.
Cut into squares, top with a Candy Corn kernel and ENJOY!
