No-cook fudge and no-churn ice creams are my favorite easy desserts for just about any occasion. So naturally, with St. Patrick’s Day just around the corner, I had to make some Rainbow Fudge, a colorful and kid-friendly counterpart to my 4-Ingredient Bailey’s Fudge.

Rainbow Fudge Recipe
Unlike the majority of my no-cook fudge recipes, this recipe can be a bit time-consuming because each layer needs to be added after the previous layer has had a chance to cool and set in the fridge. Adding a layer takes just a couple minutes each time, so it’s a great recipe to work on as you find yourself in the kitchen – make a layer at breakfast, when you’re waiting for lunch, when you pop in for an afternoon coffee, etc.
There are a few different ways you can achieve the different colors for the rainbow fudge layers:
- buy candy melts/melting chocolate in each color
- buy candy melts in the primary colors (and mix for the secondary)
- buy white candy melts or chocolate and use a gel-based food coloring
For the third option, using food coloring, just ensure that your food coloring is not water-based because that can cause the chocolate or candy melts to separate and take on a curdled appearance.
I’m going to write this recipe with method #1 in mind, but if you use method #2 you’ll want 1 cup of each primary colored candy melt.

The recipes on this blog are tested with a conventional gas oven and gas stovetop. It's important to note that some ovens, especially as they age, can cook and bake inconsistently. Using an inexpensive oven thermometer can assure you that your oven is truly heating to the proper temperature. If you use a toaster oven or countertop oven, please keep in mind that they may not distribute heat the same as a conventional full sized oven and you may need to adjust your cooking/baking times. In the case of recipes made with a pressure cooker, air fryer, slow cooker, or other appliance, a link to the appliances we use is listed within each respective recipe. For baking recipes where measurements are given by weight, please note that results may not be the same if cups are used instead, and we can’t guarantee success with that method.
