Step 1

Line an 8 x 8 casserole dish with foil. Spray with nonstick spray.

Step 2

In a large microwave safe bowl place the white chocolate chips.

Step 3

Microwave on high for one minute and stir.

Step 4

Add the vanilla frosting to the melted chips.

Step 5

Microwave for 30 seconds and stir. Microwave at 15 second intervals until you achieve melted and smooth mixture.

Step 6

Measure out ¾ cup of the mixture into two different bowls and leave the remaining mixture in the original bowl. The original bowl will stay white.

Step 7

Tint each ¾ cup bowl full of fudge with red coloring and green coloring to desired depth of color.

Step 8

Drop big tablespoons of each color into the foiled pan in random patterns. Then take a table knife and run it through the fudge to create a marbled design.

Step 9

Refrigerate uncovered until set at least an hour.

Step 10

Remove the fudge from the pan and peel the foil back. Cut into squares to serve!
