Gorgeous Rainbow Fudge Recipe (2024)

Rainbow fudge is a gorgeous fudge made from six colorful layers of white chocolate fudge! It's a little time-consuming because each layer is made individually, but it's not at all difficult since it is made entirely in the microwave. You can always vary the colors of the layers to suit your tastes. Serve this beautiful and eye-catching fudge at your next party, shower, or celebration!

"A wonderful addition to any celebration. The rainbow colors draw instant excitement. And while the layers of colors require chill time in between, it's still easy and worth the trouble to produce something so fun." —Renae Wilson

Steps to Make It

Gather the ingredients.
Line a 9x9 pan with aluminum foil and spray the foil with nonstick cooking spray. A 9x9 pan produces a fudge that is a little over an inch tall. If you want taller fudge, using an 8x8 pan will produce pieces that are almost 2 inches high.
In a bowl, combine 6 ounces (about 1 cup) of white chocolate chips, 1/2 cup sweetened condensed milk, a pinch of salt, and 1/2 teaspoon of vanilla extract. Microwave the bowl for 30 seconds, then stir.
Continue to microwave the white chocolate in 15-second intervals until it is completely melted and smooth when you stir. This can take anywhere from 45 to 90 seconds, depending on the strength of your microwave. Watch it carefully, as white chocolate can easily scorch.
Once melted and smooth, add a few drops of purple gel food coloring and stir until the color is dispersed.
Scrape the fudge into the prepared pan and smooth it into an even layer. It will be very thin, but remember we are making six layers in all!
Chill the pan to set the layer in the freezer for about 10 minutes.
Repeat the process from step 2 again. This time, once your white chocolate is melted, add blue food coloring and stir until combined.
Pour the blue fudge over the purple layer and spread it out, then chill the fudge again.
Continue to repeat this process, adding green, yellow, orange, and red layers of fudge.
Once you have added your final layer, freeze the fudge until it is completely set, about 1 hour.
When you are ready to cut it, remove the fudge from the pan using the foil as handles.
Use a large sharp chef's knife to cut the fudge into small 1-inch pieces. Return the fudge pieces to the freezer and freeze overnight. Keep frozen until ready to serve. The fudge may get soft after a few hours at room temperature.

Tips

If you don't have a microwave, you can melt the chocolate using a double boiler instead. Fill a small saucepan with an inch of two of water and place a heatproof bowl on top of it. The bottom of the bowl should not be touching the water. Bring the water to a gentle simmer and melt the chocolate with the condensed milk, vanilla and salt in the bowl, stirring occasionally.
The rainbow fudge can get soft if kept out at room temperature for too long. It is best served chilled.

How to Store

Rainbow fudge can be stored in an airtight container in the refrigerator for up to a month or in the freezer for up to four months.
