Spray a baking dish with non-stick cooking spray or line with wax paper. I used a nonstick cooking spray and while the edges were difficult to remove without breaking the fudge, it came off of the bottom of my dish very easily.

Microwave your Wilton candy melts at 30 second intervals for a total of 1.5 to 2 minutes, stirring between intervals.

Once your Wilton candy melts are completely melted and stirred until smooth, pour it into a bowl with the cake frosting and mix well.

Pour into your prepared baking dish and top with sprinkles if you are adding sprinkles.

Refrigerate for about 30 minutes, then cut with a knife and remove carefully with a fork or spatula.
