Here at Ruffles and Rain Boots, we are all about making this summer more bearable for the kiddo. So much time being home and not as many trips out…well, we’re having almost weekly “mini parties” here for the family, just to add a fun twist. This week, the kiddo asked for a mermaid party so we made these fun sea shell krispies treats (and a few other things).


It was a fun way to help prep for our little under the sea party and she had a great time. If you’re ready to make a fun mermaid treat, let’s get started.

Tips to Make Sea shell Rice Krispie Treats

  • Start by getting a sea shell cookie cutter like this one. You’re going to need it–that’s how we’re getting the sea shell shape! LOL!
  • I always like to recommend using my easy no-fail rice krispies treats. They’re a super basic and easy cereal treat, but there are a few tricks there to make the recipe worth repeating.
  • Always always measure out the ingredients. Sometimes, with a “simple” recipe, it can be easy to just make it up on the fly. But if there’s a mistake that can be made with rice krispies treats, this is basically the only one. Go one way with ingredients and your treats be so gooey and floppy; go the opposite way and they’ll be exceedingly crunchy and dry. So, use the recipe–pretend we’re baking.
  • Miniature marshmallows make your rice cereal treats the best of the best. I don’t mess around with the big jumbo marshmallows. They’re basically giant fluffy useless blobs when you try to make treats with them. The mini-marshmallows melt faster and more smoothly than the big marshmallows and those itty-bitty marshmallows are just ridiculously easier to stir.
  • Before decorating the shell treats, ask the kiddo to wait until they are completely cooled. Warm treats and chocolate will result in a gooey mess.
