This easy 3-ingredient cotton candy fudge recipe combines white chocolate chips, sweetened condensed milk, and cotton-candy flavoring into a creamy, colorful candy with almost no effort. The mixture melts in the microwave in short intervals, then chills in an 8-inch square pan for about 2 hours until firm and ready to cut.
Each bite is sweet, smooth, and wonderfully nostalgic, with a soft cotton-candy flavor and a rich white chocolate finish. Pink and blue gel food coloring create the familiar fairground-inspired swirl, while cotton candy pieces or sprinkles add a playful touch without counting toward the three essential ingredients.

Ingredients You’ll Need
The main formula uses exactly three ingredients, and each one has an important role in the finished fudge. Choose good-quality white chocolate chips when possible, since their flavor is noticeable in such a short ingredient list.
- White chocolate chips: Use 3 cups, or about 510 grams. They provide the creamy candy base and firm structure once chilled.
- Sweetened condensed milk: One 14-ounce can, or 396 grams, supplies sweetness and moisture. Be sure to use sweetened condensed milk rather than evaporated milk, which has a different consistency and is not a substitute here.
- Cotton-candy flavoring: One teaspoon gives the fudge its recognizable spun-sugar taste. Cotton-candy extract or flavoring works well.
Pink and blue gel food coloring are optional extras for the classic two-tone look. Cotton candy pieces and sprinkles are also optional decorations, so the fudge remains a true three-ingredient recipe without them.

How to Make It Step-by-Step
Step 1: Prepare the pan before melting anything. Line an 8-inch square pan with parchment paper, pressing it into the corners and leaving an overhang on two opposite sides so the firm fudge can be lifted out easily.
Step 2: Place the white chocolate chips and sweetened condensed milk in a microwave-safe bowl. Microwave the bowl for 30 seconds, then remove it and stir thoroughly, even if the chips do not look very melted yet.
Step 3: Continue microwaving in 30-second intervals, stirring well after each one, until the mixture becomes smooth and glossy. The total microwave time is usually about 1 to 3 minutes, but the exact time can vary with your microwave and bowl.
Step 4: Stop heating as soon as the mixture is smooth, then stir in the cotton-candy flavoring. The residual heat will finish melting any tiny pieces, while additional heating can scorch the white chocolate or cause it to seize.
Step 5: Divide the flavored mixture evenly between two small bowls. Add a small amount of pink gel coloring to one bowl and blue gel coloring to the other, stirring gently until the shades are even.
Step 6: Spoon alternating portions of the pink and blue fudge into the parchment-lined pan. Place the colors close together so the finished slices show a pretty pattern rather than separate blocks.
Step 7: Use a knife or skewer to make gentle swirls through the two colors. Work with a light touch and stop early, because too much swirling can blend the pink and blue into a muddy shade.
Step 8: Refrigerate the pan for about 2 hours, or until the fudge is completely firm in the center. Lift it out by the parchment, place it on a cutting board, and cut it into 16 to 24 squares with a sharp knife.
Pro Tips for Smooth, Colorful Fudge
White chocolate needs a little care because it can scorch more easily than semisweet or dark chocolate. Short microwave intervals and thorough stirring are more reliable than one long heating cycle.
- Use gel coloring: Gel food coloring creates vivid pink and blue shades without adding excess liquid. Liquid coloring can thin the mixture or make the color less intense.
- Stir patiently: A bowl of white chocolate may look lumpy even though the chips are soft enough to melt with stirring. Give it a good stir before deciding it needs another microwave interval.
- Measure the flavoring: One teaspoon is enough to provide a clear cotton-candy note without overpowering the creamy white chocolate.
- Swirl sparingly: Two or three gentle passes with a skewer are usually enough. The more distinct the colors look in the pan, the prettier the slices will be.
- Cut cleanly: Let the fudge become fully firm before slicing. A sharp knife warmed under hot water and dried thoroughly can make neat cuts, but do not use a wet knife around the candy.

Serving Ideas and Decoration
Serve the fudge chilled or let it stand at room temperature for a few minutes before eating. That brief rest softens the texture slightly and brings out the creamy white chocolate flavor.
For a party-ready presentation, arrange the squares on a white platter or pastel cake stand. Add cotton candy pieces immediately before serving, since cotton candy can dissolve when exposed to moisture in the air.
Pastel sprinkles, tiny sugar pearls, or a light dusting of edible shimmer can also complement the swirled design. Keep decorations delicate so they add color and texture without hiding the pink-and-blue pattern.
This candy also makes a charming edible gift. Place individual pieces in small paper cups, then pack them in a box or clear treat bag tied with a pastel ribbon.

Storage and Make-Ahead Advice
Store the finished fudge in an airtight container in the refrigerator. Separate layers with parchment or wax paper to keep the squares from sticking together, and enjoy them within about one to two weeks for the best texture and flavor.
The fudge can be made ahead for a party because it needs approximately 2 hours to firm in the refrigerator. For the cleanest appearance, keep the slab chilled until shortly before slicing and decorating.
Freezing is possible, although refrigeration is usually sufficient for this small batch. If you freeze it, wrap the pieces well, place them in an airtight container, and thaw them in the refrigerator to reduce condensation on the surface.
Do not leave the fudge in a warm room for an extended period, especially if it is decorated with cotton candy. Heat can soften the squares, while humidity can make the garnish lose its fluffy texture.
