Servings 8


  • 1/2 cup Wilton Turquoise Candy Melts
  • 1/3 cup Wilton Bright White Candy Melts
  • 2 teaspoons canola or vegetable oil (optional)
  • 8 0.78 oz Kellogg's Rice Krispie Treats Original (or homemade)
  • 8 0.4 oz Kellogg's Rice Krisipie Treats Mini
  • Assorted sprinkles
  • paper straws


  1. Line large baking sheet with silicone baking sheet, parchment paper or aluminum foil. Set aside.

  2. Soften fondant if necessary following package instructions and roll out to an even thickness. (Try not to make it super thick or very thin.) 

  3. Press small mermaid tail cutter into fondant. Gently remove fondant tail and smooth edges with fingers or food safe brush. Place on lined baking sheet. Repeat. Set aside. 

  4. Remove larger cereal treats from packaging. Cut paper straws in half and insert them into the bottom of the cereal treat so the reach halfway up.

  5. Melt candy melts in microwave in intervals, stirring often, just until full melted. Stir in oil for a smooth consistency.

  6. Carefully spread candy melts over top of cereal treat with small metal spatula. 

  7. Immediately add mermaid tail so the fins are upright. (Your straw should be on top).

  8. Top with a few sprinkles to the sides of the fondant tail. Set aside on baking sheet to dry completely at room temperature. Repeat with remaining cereal treats on a stick.

  9. For mini cereal treats, cut mermaid tails in half so fins are still intact but the tail is shorter. Follow same process as above with using cut tails instead. If you would like them on a stick, cut a paper straw into thirds instead of in half. Set aside to dry at room temperature.

  10. Store in airtight container until ready to serve.
