Ingredients Needed
Before you dive into making this colorful, magical treat, let’s get everything you need lined up. The great thing about this Rainbow Unicorn Fudge Recipe is that it uses simple, easy-to-find ingredients you might already have in your pantry. Here’s a full breakdown so you can be sure you’re ready to go.
Sweetened Condensed Milk

The foundation of any good fudge is a creamy, rich base, and that’s exactly what sweetened condensed milk delivers. You’ll need one 14-ounce can for this Rainbow Unicorn Fudge Recipe. It not only adds sweetness but also helps keep the fudge smooth and easy to work with.
White Chocolate Chips
For that melt-in-your-mouth texture, white chocolate chips are a must. You’ll need about 3 cups for this recipe. White chocolate also works perfectly as a base for adding bright, beautiful colors without affecting the flavor too much.
Vanilla Extract
A teaspoon of vanilla extract adds a gentle, warm flavor that balances out the sweetness. It’s a small but important addition that rounds out the taste of your colorful fudge.
Food Coloring Gels
This is where the magic happens. Use food coloring gels instead of liquid dyes, as they provide bold, vibrant colors without thinning your mixture. Popular picks for a Rainbow Unicorn Fudge Recipe include pastel pink, lavender, aqua blue, and sunshine yellow. You can stick with a classic unicorn palette or get creative with your own color combos.
Edible Glitter or Sprinkles
No unicorn-inspired treat would be complete without a little sparkle. Edible glitter or a fun mix of colorful sprinkles can be scattered on top of the fudge before it sets. It adds a playful, magical touch that makes this recipe party-ready.
Mini Marshmallows (Optional)
If you’d like to give your fudge a bit of texture and extra sweetness, fold in a handful of mini marshmallows before adding the colors. They melt slightly into the fudge, creating pockets of soft, chewy goodness.
Flavor Extracts (Optional)
While vanilla is the go-to, feel free to experiment with other extracts like almond, coconut, or strawberry for a custom flavor twist. Just a few drops can make a fun difference and give your Rainbow Unicorn Fudge Recipe a unique spin.
Candy Decorations (Optional)
Small candy pearls, edible stars, or tiny heart-shaped candies make adorable finishing touches. Scatter them on top with your glitter for an extra dose of charm and color.
Tools You’ll Need
Before you get started on this colorful dessert, it’s a good idea to round up the tools you’ll need to make your Rainbow Unicorn Fudge Recipe a smooth, stress-free experience. The great thing about this recipe is that it doesn’t call for any fancy equipment. Most of these tools are probably already in your kitchen, and having them ready will make the whole process a lot easier.
Medium Saucepan
A good medium-sized saucepan is essential for gently melting the white chocolate chips with the sweetened condensed milk. Make sure it’s heavy-bottomed to avoid any burning or sticking. A non-stick saucepan works especially well for this recipe, keeping cleanup simple and preventing your fudge base from scorching.
Heatproof Spatula
You’ll need a sturdy, heatproof spatula for stirring the mixture as it melts and to scrape down the sides of the pan. A silicone spatula works best because it can handle high heat and makes mixing smooth and easy.
Mixing Bowls
Several small mixing bowls will come in handy when it’s time to divide your fudge mixture and add the different food colorings. Choose bowls that are microwave-safe in case you need to gently reheat portions of the fudge for easier swirling.
8×8-inch Baking Pan
An 8×8-inch baking pan is the perfect size for this Rainbow Unicorn Fudge Recipe. It keeps your fudge thick enough for neat squares but not too tall. You can also use a square silicone pan if you have one — it makes removing the set fudge super simple.
Parchment Paper
Lining your baking pan with parchment paper makes it much easier to lift the fudge out once it’s set. Leave some extra paper hanging over the sides for easy removal and cleaner cutting.
Toothpicks or Skewers
To get those gorgeous rainbow swirls, you’ll want a toothpick or a skewer to gently swirl the different colors together before adding your sprinkles and glitter on top.
Step-by-Step How to Make Rainbow Unicorn Fudge
Making this colorful, sweet treat is much easier than it looks. This Rainbow Unicorn Fudge Recipe doesn’t require a candy thermometer or complicated techniques — just a little patience and creativity. Follow these simple steps and you’ll have a batch of gorgeous, swirled fudge ready to brighten up any day.

Step 1: Prepare Your Pan
Start by lining an 8×8-inch baking pan with parchment paper. Make sure to leave a bit of overhang on the sides so you can easily lift out the fudge once it’s set. Lightly grease the paper if you’re worried about sticking, though with parchment, it usually isn’t a problem.
Step 2: Melt the Base Ingredients
In a medium, heavy-bottomed saucepan, combine the white chocolate chips and sweetened condensed milk over low heat. Stir continuously with a heatproof spatula to ensure the chocolate melts smoothly and doesn’t scorch. This should take about 5 to 7 minutes. Once fully melted and creamy, stir in the vanilla extract for that extra layer of flavor.
Step 3: Divide and Color the Fudge
Now for the fun part. Divide the melted fudge mixture evenly into several small bowls — one for each color you plan to use. Add a small amount of gel food coloring to each bowl and stir well until the colors are vibrant and fully blended. Popular choices for a Rainbow Unicorn Fudge Recipe include pink, blue, yellow, and purple, but you can get creative with whatever shades you love.
Step 4: Layer and Swirl the Colors
Drop spoonfuls of each colored fudge mixture randomly into the prepared pan, layering them over one another. Continue adding the colors until all the fudge is in the pan. Then, using a toothpick or skewer, gently swirl the colors together to create that signature marbled, rainbow effect. Be careful not to overmix — you want to see distinct swirls of color.
Step 5: Add the Sparkle
Before the fudge sets, sprinkle the top generously with edible glitter, rainbow sprinkles, or candy pearls. This step turns your fudge into a truly magical treat, perfect for birthdays, parties, or a little pick-me-up on a dull day.
Step 6: Chill Until Firm
Place the pan in the refrigerator for at least 2 to 3 hours, or until the fudge is completely set. You can also leave it overnight if you’re prepping it ahead of time. The fudge should be firm to the touch and easy to lift from the pan using the parchment paper overhang.
Step 7: Cut and Serve
Once the fudge is set, lift it out of the pan and transfer it to a cutting board. Use a sharp knife to cut it into small, even squares. If you’d like cleaner edges, you can wipe the knife with a damp cloth between cuts. Now your Rainbow Unicorn Fudge Recipe is ready to enjoy!
Bonus Tips
For an extra-special touch, consider adding mini marshmallows or crushed candy pieces to the fudge before swirling in the colors. You can also experiment with different extract flavors, like almond or strawberry, to make each batch a little different. Store your finished fudge in an airtight container in the fridge, where it’ll stay fresh for up to a week — though it rarely lasts that long!
Pro Tips for Perfect Unicorn Fudge
Making this sweet, colorful treat is already simple, but a few extra tips can help you get the smoothest texture, brightest colors, and prettiest swirls every time. Here are some helpful pointers to make sure your Rainbow Unicorn Fudge Recipe turns out picture-perfect.
Use Gel Food Coloring for Bold Colors
When it comes to achieving those bright, vibrant shades, gel food coloring is your best friend. It’s more concentrated than liquid food dye, so you only need a small amount to get rich, bold colors without thinning out your fudge mixture. This keeps the texture firm and helps your swirls hold their shape beautifully.
Stir Constantly While Melting
White chocolate can be a little temperamental when it comes to heat, so it’s important to melt it slowly and stir constantly. Use a low heat setting and a heatproof spatula to gently stir the mixture as it melts. This prevents scorching and ensures your fudge base stays smooth and creamy without any lumps.
Don’t Over-Swirl the Colors
It can be tempting to keep swirling the colors together, but less is more when it comes to creating those beautiful, distinct rainbow patterns. Use a toothpick or skewer to gently swirl just a few times. Overdoing it will blend the colors too much, turning your fudge into one single shade instead of the dreamy, marbled look you want.
Add Sprinkles and Glitter Quickly
The fudge starts to set as soon as you pour it into the pan, so be ready with your edible glitter and sprinkles. Add them right after swirling the colors while the surface is still soft. This helps them stick properly and ensures they become part of the finished fudge without falling off later.
Chill Until Completely Set
For clean, easy cutting, make sure your fudge is fully set before slicing it into squares. Chill it in the refrigerator for at least 2 to 3 hours, or until it’s firm to the touch. If you try to cut it too soon, it might be sticky or uneven, so a little patience goes a long way.
Follow these simple pro tips, and your Rainbow Unicorn Fudge Recipe will look magical and taste absolutely dreamy every single time.
Storage and Shelf Life
Once you’ve whipped up your colorful batch of fudge, knowing how to store it properly will help keep it tasting fresh and looking beautiful. This Rainbow Unicorn Fudge Recipe holds up well when stored the right way, making it perfect for prepping ahead for parties or gifting.
How to Store Unicorn Fudge
After your fudge has fully set and been cut into squares, place the pieces in an airtight container. If you’re stacking them, separate each layer with a piece of parchment paper to prevent sticking.
Store the container in the refrigerator to keep the fudge firm and maintain its creamy texture. Though it’s safe to leave it out at room temperature for short periods during parties or events, it’s best kept chilled for everyday storage.
How Long Does Unicorn Fudge Last?
When stored properly in an airtight container in the refrigerator, your Rainbow Unicorn Fudge Recipe can stay fresh for up to 7 days. The colors stay vibrant, the texture stays smooth, and the fudge maintains its rich flavor.
If you need to store it for longer, you can freeze the fudge for up to 2 months. To freeze, wrap individual pieces in parchment or wax paper, then place them in a freezer-safe bag or container. When you’re ready to enjoy it, just thaw the fudge in the refrigerator overnight.
Fun Variations to Try
While the Rainbow Unicorn Fudge Recipe is already a delightful treat, there’s always room for a little creativity. Here are a few fun variations to customize your fudge and make it even more magical.
Add Flavor Extracts
For a unique twist, try adding different flavor extracts to the fudge mixture. Almond, strawberry, or even orange extracts can give your Rainbow Unicorn Fudge a custom flavor that complements the colorful swirls. Just a teaspoon can make a big difference!
Mix in Candy Pieces
To add texture and extra sweetness, fold in small candy pieces like mini marshmallows, crushed Oreos, or colorful candy sprinkles. This gives your fudge an added crunch and even more fun flavors.
Experiment with Color Themes
While classic rainbow colors are beautiful, you can switch it up with different color themes. Think pastel shades for a soft look, or go for a bold theme like neon pinks, blues, and greens for an edgy, vibrant finish. You can even match the colors to a holiday or event!
Try Chocolate Fudge Layers
If you love chocolate, add a layer of chocolate fudge at the bottom of your pan before adding the colorful layers. The rich chocolate flavor pairs perfectly with the creamy, colorful fudge for a delicious twist.
