Ingredients for Cotton Candy Fudge

Here’s everything you’ll need to whip up this dreamy carnival-inspired treat—I promise it’s all simple stuff you can find at any grocery store (or probably already have in your pantry!):

• 3 cups white chocolate chips (Go for the good stuff here—higher quality chips melt smoother and taste better. I’m partial to Ghirardelli, but any premium brand will do.)
• 1 can (14 oz) sweetened condensed milk (That iconic Eagle Brand yellow can—don’t confuse it with evaporated milk!)
• 1 tsp pure vanilla extract (The real deal makes a difference here—that imitation stuff just won’t give you the same depth of flavor.)
• 1/2 cup cotton candy flavored syrup (Taste as you go—some brands are sweeter than others. I usually start with 1/3 cup and add more if needed.)
• Pink and blue gel food coloring (This is KEY—the gel gives you those vibrant carnival colors without watering down your fudge.)
• Sprinkles (Optional, but highly recommended for extra fun! The jimmie-style ones work better than nonpareils which can bleed color.)

Ingredient Substitutions & Notes

Ran out of something? No worries—here are my tried-and-true swaps:

• Vanilla bean paste works beautifully instead of extract—use the same amount. You’ll get those pretty little specks throughout your fudge too!
• Can’t find cotton candy syrup? Make your own by blending 1/4 cup corn syrup with 1 tsp cotton candy flavoring oil (the kind used for candy making).
• Emergency warning: Don’t use liquid food coloring! It’ll make your fudge seize up and get grainy. If you absolutely must, use just 1-2 drops max.
• For a pastel version, use white chocolate melts instead of chips—they give a softer set that’s perfect for baby showers.
• Allergic to dairy? Coconut condensed milk works surprisingly well, though the flavor will be slightly different.

Remember—great fudge starts with great ingredients. Trust me, splurging on that good vanilla and premium chocolate makes all the difference between “nice” and “OMG I need this recipe!”

How to Make Cotton Candy Fudge

Alright, let’s get to the fun part—making this dreamy carnival treat! I promise it’s easier than you think, but I’ll walk you through each step because I’ve learned (the hard way!) where the little pitfalls are. Follow these simple steps, and you’ll have perfect cotton candy fudge every time.

Step 1: Prep the Pan

First things first—let’s set up our fudge’s cozy home. Grab your 8×8-inch pan (that’s standard brownie size) and line it with parchment paper. Here’s my trick: cut a piece that’s slightly larger than the pan so you’ve got some overhang on two opposite sides—these will become your “handles” later for lifting the fudge out. Lightly press the paper into the corners (a dab of butter helps it stick if it’s being stubborn). Now you’re ready for the good stuff!

Step 2: Melt the Base

Time to work some microwave magic! In a large microwave-safe bowl (I like using my glass mixing bowl), combine the white chocolate chips and sweetened condensed milk. Microwave in 30-second bursts—no cheating with longer times! After each blast, stir well before putting it back in. It usually takes me about 3 rounds to get that perfectly smooth consistency.

Watch out for this: If you rush it, the chocolate can scorch or the mixture might get grainy. When it’s ready, it should look like liquid silk—no lumps! This is also when you’ll stir in the vanilla and cotton candy syrup. Taste it (careful, it’s hot!) and add more syrup if you want that flavor to really pop.

Step 3: Flavor & Color

This is where the carnival magic happens! Divide your smooth mixture evenly between two bowls (I just eyeball it—no need to dirty your measuring cups again). Now for the fun part: add a few drops of pink gel coloring to one bowl and blue to the other. Start with just a drop or two—you can always add more color but you can’t take it away! Stir each until you get those perfect pastel shades.

Now alternate spoonfuls of the pink and blue mixtures into your prepared pan. When all the batter is in, take a butter knife and gently swirl through the colors just 2-3 times—any more and you’ll get muddy purple fudge instead of pretty swirls. Sprinkle on your jimmies now if you’re using them!

Step 4: Chill & Serve

Patience time! Pop your pan into the fridge and let it chill for at least 2 hours—I know, the waiting is torture! This is when the fudge sets up perfectly. When it’s ready, use those parchment paper handles to lift it out in one beautiful slab onto a cutting board.

Here’s my cutting secret: run a sharp knife under hot water, dry it quickly, and make your cuts. Wipe and reheat the knife between slices for super clean edges. I usually get about 16 perfect little squares, but hey—no judgment if you want to cut them bigger!

Now step back and admire your handiwork—those swirls, those colors! This is the kind of treat that makes people’s eyes light up. Store any leftovers (ha, as if!) in an airtight container between layers of parchment. They’ll keep beautifully for about a week… if they last that long!

Tips for Perfect Cotton Candy Fudge

Okay, I’ve made this fudge more times than I can count—sometimes perfectly, sometimes with hilarious disasters (we don’t talk about The Purple Mud Incident of 2020). Here are my hard-earned secrets for cotton candy fudge that’ll make you look like a baking rockstar:

• Gel food coloring is your BFF: Those liquid drops? They’ll ruin your fudge’s texture faster than you can say “rainbow fail.” The gel kind gives you those bright carnival colors without watering down your mixture. A little goes a long way—start with just a toothpick’s worth!
• Room temp ingredients mix better: Let your sweetened condensed milk and vanilla sit out for about 20 minutes before starting. Cold ingredients can make the chocolate seize up—trust me, nobody wants lumpy fudge.
• Swirl like you mean it (but not too much!): That marble effect is gorgeous when you get it right. Here’s my method: make exactly three slow “S” shapes through the pan with your knife. Any more and your pretty pink and blue will turn into sad purple mush.
• Microwave in baby steps: I know it’s tempting to nuke it for a full minute, but resist! 30-second bursts with stirring in between keeps your chocolate silky smooth. Burnt chocolate smells awful and ruins the whole batch.
• Hot knife = clean cuts: When it’s time to slice, run your knife under very hot water and dry it quickly between each cut. This gives you those Instagram-worthy sharp edges instead of crumbly messes.

Oh! One more thing—if your fudge starts setting up too fast while you’re working with it, just pop the bowl back in the microwave for 10 seconds. It’s like hitting the reset button for perfect swirls. Now go forth and make magic happen!

Storage & Serving Suggestions

Okay, here’s the deal – this cotton candy fudge is so good it probably won’t last long, but just in case you need to store some (maybe hide a few pieces from the kids?), here’s how to keep it tasting fresh and fabulous:

Airtight is the way to go: I always use a glass container with a tight-fitting lid – those plastic ones can sometimes make the fudge taste… well, plasticky. If you’re stacking pieces (good luck having leftovers!), put a small sheet of parchment paper between layers so they don’t stick together. It’ll stay perfect in the fridge for about a week – if it lasts that long!

Serving temperature matters: I know it’s tempting to eat it straight from the fridge (no judgment here!), but let me tell you a secret – this fudge tastes even better at room temperature. Take it out about 15 minutes before serving to let the flavors really bloom. That cotton candy flavor pops more when it’s not ice cold!

Presentation pro-tip: For parties, I love arranging the squares on a white platter with a few extra sprinkles scattered around. If you really want to go all out, serve it with mini paper cones like they use at carnivals – it makes the whole experience even more fun!

One last thing – this fudge actually freezes surprisingly well for up to a month if you wrap it tightly in plastic wrap first, then foil. Perfect for when you need a quick dessert for unexpected guests! Just thaw it in the fridge overnight, then let it come to room temp before serving.
