3–4 cups confectioners’ sugar

Kitchen Equipment Needed
Before you get started, gather the following tools:
-
Large mixing bowls
-
Electric mixer (hand or stand)
-
Measuring cups and spoons
-
Spatula
-
Two 12-cup muffin tins
-
18 paper cupcake liners
-
Toothpicks
-
Piping bag with a large star tip
-
Small bowls for dividing batter and frosting
-
Popsicle sticks for garnishing
Step-by-Step Instructions
1. Preheat and Prep
Start by preheating your oven to 350°F (175°C). Line two standard muffin tins with 18 paper liners.
2. Make the Cupcake Batter
In a large bowl, combine:
-
1 box white cake mix
-
4 egg whites
-
1/2 cup vegetable oil
-
1 cup water
-
1 tbsp cotton candy flavoring
Mix on medium speed for about 2 minutes until the batter is smooth and lump-free.
3. Add the Color
Divide the batter evenly between two bowls. Add a few drops of pink food coloring to one bowl and blue to the other, mixing until fully combined.
4. Fill and Bake
Layer the pink and blue batters into the cupcake liners, alternating colors without swirling them. Fill each liner about 3/4 full.
Bake for 15–18 minutes or until a toothpick inserted comes out clean. Let them cool in the pans for 5 minutes, then transfer to a wire rack to cool completely.
5. Make the Cotton Candy Frosting
In a medium bowl, cream together:
-
3/4 cup softened unsalted butter
-
1/2 tsp vanilla extract
-
1 – 1 1/2 tsp cotton candy flavoring
Gradually add 3–4 cups of confectioners’ sugar, alternating with 1/4 cup heavy cream, until the frosting is light, fluffy, and holds its shape.
Split the frosting into two bowls and color one pink and the other blue.
6. Pipe the Frosting
Fit a piping bag with a large star tip. Carefully spoon the pink frosting down one side and the blue on the other side of the bag to create a swirl effect.
Pipe generous swirls on top of each cooled cupcake.
7. Decorate Like a Pro
Sprinkle with pink and blue sanding sugar. For the final whimsical touch, attach small tufts of cotton candy to the ends of popsicle sticks and gently insert them into the cupcakes.
Tips, Swaps & Variations
-
Flavor Swap: No cotton candy flavoring? Try using raspberry or bubblegum extract for a fun twist.
-
Vegan-Friendly: Use a vegan white cake mix and replace egg whites with aquafaba (chickpea brine).
-
All-Natural Colors: Use plant-based food coloring powders (like beetroot and spirulina) for a natural look.
-
Batter Swirl: For a marbled effect, lightly swirl the pink and blue batters with a toothpick before baking.
-
Party Hack: Pre-make and freeze unfrosted cupcakes. Just thaw and decorate on party day.
How to Store Leftovers
Cotton candy cupcakes are best enjoyed the day they’re made, but here’s how to store them:
-
Without Cotton Candy Garnish: Store frosted cupcakes in an airtight container at room temperature for up to 3 days or refrigerate for up to 5.
-
With Cotton Candy: The cotton candy will dissolve quickly due to moisture, so add it just before serving.
-
Freezing: You can freeze the cupcakes (without frosting) for up to 3 months. Wrap them tightly in plastic wrap and then in foil. Thaw at room temperature.
Food & Drink Pairings
These cupcakes are a sweet star, so pair them with lighter sips and sides:
-
Drink Pairings: Vanilla milkshakes, strawberry lemonade, or a sparkling rosé for adults.
-
Food Pairings: Serve with finger foods like fruit skewers, popcorn, or mini sandwiches for a carnival-inspired spread.
Frequently Asked Questions (FAQ)
Can I use a homemade cake batter instead of a boxed mix?
Absolutely! Use your favorite white cake recipe, just be sure to replace any yolks with whites to keep the color vibrant for tinting.
Where can I find cotton candy flavoring?
Look for it in specialty baking stores or online retailers. Brands like LorAnn offer a strong, concentrated version perfect for frosting and batter.
Can I make mini cupcakes instead?
Yes! This recipe yields about 36 mini cupcakes. Bake for 10–12 minutes and reduce decorating quantities accordingly.
How do I keep cotton candy from melting on the cupcakes?
Add it just before serving. The frosting’s moisture causes the cotton candy to dissolve over time, so it’s best applied last-minute.
Can I make these gluten-free?
Yes, simply use a gluten-free white cake mix and double-check all flavorings and decorations for gluten-containing ingredients.
