Those who know me know that I’m a sucker for sugar. I try to keep my cravings in control, but let’s face it – sugar is tasty. There’s no more sugary treat than cotton candy . . . it’s basically a spun sugar recipe!

Cotton candy reminds me of fun times with my family at the state fair, and warmer weather, and that’s the entire inspiration behind this cotton candy rice crispy treats recipe.

Yes – these rice crispy treats have a few handfuls of cotton candy within that you can taste when you eat them.

They’re actually quite decadent, and perfect for serving at a circus/carnival party. If you’re interested in a unique rice crispy treats recipe that everyone is going to love, give this a try!

Tips and Thoughts for This Recipe

  • Don’t take your eyes off the pot as you melt the marshmallows and keep stirring. You don’t want the marshmallows to burn.
  • I like to use a piece of waxed or parchment paper that I’ve sprayed with oil to press the treats firmly and evenly into the edges and corners, though a silicon spatula works almost as well. Some people even use a plastic bag sprayed with oil.
  • You might get tempted to add more marshmallow, but stick with what I suggest here. Too much marshmallow causes these to get sticky and fall apart.
  • These last 2 – 3 days in an airtight container on the counter, and maybe a little bit longer in the fridge.
