Why I Love This Recipe

I love how this cotton candy milkshake turns any day into a celebration. It captures that classic fairground cotton candy flavor and takes it to another level with colorful toppings like sprinkles, whipped cream, and a big puff of cotton candy. I also like that I don’t need any special equipment—just a blender, a few ingredients, and a little creativity. Whether I’m making it for a birthday party or just having fun with the kids, this one always gets a big smile.

Ingredients

(Here’s a tip: Check out the full list of ingredients and measurements in the recipe card below.)

• 3 cups vanilla ice cream

• 1.5 cups whole milk

• 1 teaspoon cotton candy extract

• 2–3 drops food dye (pink, blue, green—whatever matches the cotton candy)

• ¼ cup white chocolate

• 2–4 tablespoons rainbow sprinkles

• 1 cup cotton candy (I like to use pink and blue)

• Toppings of choice: whipped cream, sprinkles, rock candy, lollipops, etc.

Directions

1. I start by melting the white chocolate on a small plate in the microwave using 20–30 second intervals.

2. Once melted, I dip the rim of each milkshake glass into the chocolate, then roll them in sprinkles while the chocolate is still wet.

3. I set the decorated glasses aside to harden.

4. In a blender, I combine the ice cream, whole milk, cotton candy extract, and food coloring. Then I blend it for about 30 seconds until smooth.

5. I pour the milkshake into the prepared glasses and top with a fluffy cloud of cotton candy and any extra toppings I want—whipped cream, glitter sugar, a rock candy stick, you name it.

Variations

I like to switch up the colors depending on the occasion:

• Pink Milkshake: Add pink food coloring and top with strawberry drizzle, pink sprinkles, and pink cotton candy.

• Blue Milkshake: Use blue dye and top with blue rock candy and whipped cream.

• Purple Milkshake: Mix one drop each of pink and blue dye for a dreamy purple color.

• Yellow Milkshake: Use yellow dye and lemon rock candy for a zesty twist.

• Rainbow Milkshake: Make mini batches in different colors and layer them in the glass. It looks stunning with rainbow sprinkles and a swirl lollipop.

Storage/Reheating

Milkshakes don’t store well for long periods, so I always serve them right after blending for the best texture and flavor. If I need to prep early, I’ll blend the shake and store it in the freezer for up to an hour, then re-blend briefly before serving. I don’t recommend reheating, since it’s meant to be served cold.

FAQs

How can I make the milkshake thicker?

I usually add less milk or use frozen milk cubes. Adding more ice cream also works if I want it extra thick.

Can I make this milkshake without cotton candy extract?

Yes, but it won’t have that true cotton candy flavor. I’ve tried using a bit of marshmallow extract or extra vanilla as a substitute—it’s still tasty.

How do I keep the cotton candy from melting on top?

I place the cotton candy on right before serving. If it sits too long, it starts to melt from the moisture in the shake.

What’s the best way to decorate the glass?

I melt white chocolate, dip the rim, and then roll it in sprinkles. It sticks really well and adds a festive touch.

Can I make this dairy-free?

Absolutely. I’ve made it with dairy-free ice cream and almond or oat milk. The flavor is still fun, just slightly different in texture.

Conclusion

This cotton candy milkshake recipe is one of my favorite ways to bring fun into the kitchen. It’s playful, sweet, and completely customizable. I love that I can get creative with the colors and toppings—and the kids always have a blast making their own. If I want a treat that’s equal parts delicious and fun, this milkshake is a guaranteed win.
