- 2 cups (12 oz) white chocolate chips
- 1 can (16 ounces) vanilla frosting
- red and blue food coloring
1. Prepare an 8x8 pan by lining it with aluminum foil and spraying the foil with nonstick cooking spray.
2. Place 4 ounces (about 2/3 cup) white chocolate chips in a large microwave-safe bowl. Microwave until melted, about 1-1/2 minutes, stirring halfway through the cooking time.
3. Stir until the chocolate is a smooth paste. Once the chocolate is smooth, add approximately 1/3 of the frosting and a few drops of red food coloring. Stir to combine, and adjust the coloring amount until you get a red you are satisfied with.
4. Pour the red fudge into the prepared pan and refrigerate until mostly set, 45 minutes-1 hour. The fudge does not have to be rock hard, but should be set enough so that it doesn’t move when the pan is tilted.
5. Repeat steps 2 and 3, omitting the food coloring. Pour the white-colored fudge over the red fudge and return to the refrigerator to allow the new layer to set.
6. Repeat steps 2 and 3 once more, this time adding a few drops of blue food coloring. Pour the blue fudge over the white layer and return to the refrigerator once more. Allow to set fully, about 2 hours.
7. To serve, cut into 1-inch squares. Be sure to use a large knife with a smooth blade, and wipe the blade frequently to ensure that the sides of the fudge squares do not get smeared with other colors. Stored in an airtight refrigerated container this fudge will last for up to a week.
