- Pull apart pieces of red cotton candy and press them into the top of each cupcake to create wild hair.
- Serve within a few hours for the best cotton candy texture.
Helpful Tips and Substitutions
Gel food coloring works better than liquid because it creates a more vibrant blue without thinning the batter.
If you cannot find candy eyes, use small white candies with black icing dots.
Red yarn or pipe cleaners can substitute for cotton candy if you want a non-edible version that lasts longer.
Frost the cupcakes up to a day ahead, but add the cotton candy right before serving or it will dissolve.
Use a store-bought vanilla frosting tinted blue if you want to skip making frosting from scratch.
Keep cupcakes away from humidity to protect the cotton candy hair.
Serving Ideas
Display the cupcakes on a cupcake stand arranged in alternating Thing 1 and Thing 2 rows.
Pair with Cat in the Hat themed plates and napkins for a complete party setup.
Set out extra cotton candy so kids can add more hair if they want.
Package individual cupcakes in clear boxes as party favors.
Serve alongside other Seuss-themed treats for a full dessert table.
Make-Ahead and Storage
Bake the cupcakes up to 2 days ahead and store them unfrosted in an airtight container at room temperature.
Make the frosting up to 3 days ahead and refrigerate it, then bring to room temperature and re-whip before using.
Frosted cupcakes without cotton candy can be stored in the refrigerator for up to 3 days.
Do not freeze decorated cupcakes because the candy eyes and cotton candy will not hold up.
Add the cotton candy hair no more than 2 hours before serving for the best results.
Let the Fun Begin
These cupcakes look impressive but come together easily with store-bought shortcuts.
The cotton candy hair is what makes them special, so do not skip that step.
Kids will remember these long after the party is over.
