How to Make Galaxy Swirl Cotton Candy Fudge Recipe
Step 1: Prepare Your Pan
Start by lining an 8×8-inch baking dish with parchment paper, making sure you leave some overhang on all sides. This little trick ensures you can easily lift the fudge out when it’s time to cut, preventing any stickiness or mess.
Step 2: Melt the Base Ingredients
In a medium saucepan over medium heat, melt the white chocolate chips, sweetened condensed milk, and unsalted butter together. Stir constantly to avoid burning and to create a smooth, silky mixture that’s ready to transform into fudge.
Step 3: Add Flavors
Once your mixture is perfectly smooth, remove the pan from the heat. Stir in the cotton candy extract and vanilla extract, mixing until the flavors meld. This is where your fudge starts to step into its unique, nostalgic personality.
Step 4: Divide and Color
Split the fudge mixture into three equal bowls. Into each bowl, add a few drops of pink, blue, or purple food coloring. Stir each portion thoroughly so the color infuses completely, creating vibrant layers for your cosmic masterpiece.
Step 5: Create the Galaxy Swirl
Alternate spoonfuls of each colored fudge into the prepared baking dish, layering them to create depth. Use a toothpick or skewer to delicately swirl the colors together—you want to mimic the swirling patterns of a galaxy. This step is part art, part joy, so take your time!
Step 6: Set the Fudge
Let your swirled fudge set at room temperature for 2 to 3 hours or place it in the refrigerator for about 1 hour to firm up. The texture should be perfectly soft yet hold its shape when sliced.
Step 7: Slice and Garnish
Once firm, use the parchment overhang to lift the fudge from the pan and onto a cutting board. Cut into 16 squares for perfectly sized treats. If you like, sprinkle edible glitter or colorful sprinkles on top for a little extra sparkle that makes it pop.

Make Ahead and Storage
Storing Leftovers
Store your fudge in an airtight container at room temperature for up to one week. Keeping it sealed prevents the fudge from drying out and helps the flavors stay vibrant for each indulgent bite.
Freezing
If you want to keep the fudge longer, wrap individual squares tightly in plastic wrap and place them in a freezer-safe bag or container for up to 3 months. Thaw overnight in the refrigerator before enjoying.
Reheating
The fudge is best enjoyed as is, but if you want it slightly softer, leave it at room temperature for about 15 minutes before serving. Avoid microwaving as it can melt the texture and lose the beautiful swirl effect.
FAQs
Can I substitute dark chocolate chips instead of white chocolate?
The Galaxy Swirl Cotton Candy Fudge Recipe really shines with white chocolate because it provides that creamy canvas for the cotton candy flavor and pastel colors. Dark chocolate will overpower the delicate taste and alter the look.
Is cotton candy extract easy to find?

Can I use gel food coloring instead of liquid?
Absolutely! Gel food coloring is actually preferred by many for fudge because it adds vibrant color without thinning out the mixture. Just use sparingly to achieve your desired shades.

The fudge usually sets in about 2 to 3 hours at room temperature or about an hour in the fridge. Avoid rushing this process to ensure the perfect soft but firm texture.
Can I make this fudge gluten-free?
Yes, this recipe is naturally gluten-free as long as your food coloring and sprinkles are gluten-free certified. It’s a great treat for guests with dietary restrictions!
