How to Make These Under the Sea Party Treats

To make your chocolate mermaid tails, you’ll want to use fully melted candy melts with a tiny amount of canola oil to make the chocolate smooth. This mold is very shallow and starts to set pretty fast so I recommend spreading half of your chocolate over the top and using a straight edge metal spatula to quickly even it all out. It doesn’t need to look perfect but it does need to be even so your backs are smooth. Then gently tap your mold against the counter to remove as many air bubbles as you can.

I did a chocolate mermaid tail mold comparison so I have many styles of mermaid tail molds. This 16 cavity mermaid tail mold is the only style that would work for this project. The others are just too big, thick and heavy. I like this mold but the tails are the most fragile. While the reviews are generally favorable, the most common complaint others have are how difficult it is to remove the tails without breaking them.

Tips to Remove Chocolate Mermaid Tails:

  • Do not leave a lot of chocolate around the edges of each tail when filling your mold. If it isn’t fairly clean around the edge, it is harder for the tail to come out and you’ll have to spend time removing the excess.
  • Refrigerate your tails for about 15 minutes before removal so they are nice and firm.
  • When removing them from the mold, remove them one at a time instead all at once. Do not turn them over and pop them out.
  • Work the silicone away from the tail gently from all the sides so your tail comes off easily in one piece. Do not force it.

With these chocolate tail tips, you should be able to remove all if not most of your tails without breaking them. I’ve used the mold three times now and the last time I didn’t break any.

For my under the sea dipped marshmallows, I wanted a look that resembled sea waves and foam so I marbled my chocolate. I created aqua by using turquoise melts and white melts mixed together. Then I swirled in a bit of white chocolate again. After just dipping a couple of marshmallows you will have mixed your chocolate a lot so I recommend adding dollops of additional white throughout the dipped processing, without mixing it.

You can certainly go with a solid color instead and just dip them halfway down. I wanted mine uneven like waves so I gently tipped the marshmallow over a bit while dipping. To remove excess chocolate, be sure to gently shake the excess off instead of scraping so the bottoms are nice and even.  Then add your white sprinkles and crushed graham cracker sand all the way around.

You’ll want to be sure to hold your tail in place for a good 15 seconds to make sure your tail will stay put. I loved that the tail went over the top of the marshmallow but if you need to transport your marshmallows, this would make them more susceptible to breaking the tails. I would put the tail lower on the marshmallow and pack them carefully if I needed to bring them anywhere.

I also tried out another option with these mermaid tail marshmallows. You can skip the dipping and instead use melted chocolate like glue to attach the mermaid tails to the side of the marshmallow. Then simply place them in a baking cup like this blue ombre cup to resemble ocean waves.

  • 2/3 cup turquoise candy melts
  • 1/2 cup lavender candy melts
  • 1/4 cup graham cracker crumbs
  • white nonpareils
  • silver star sprinkles
  • canola oil or shortening

Instructions

  1. Melt lavender candy melts with 1 teaspoon oil in microwave in short intervals, stirring often, just until fully melted.
  2. Spread chocolate into 16 cavity mermaid tail mold and quickly level chocolate with flat edge metal scraper, scraping off excess.
  3. Gently tap mold on hard surface to remove air bubbles. Refrigerate for 15 minutes or until firm. (Be sure mold is level in fridge.)
  4. Gently remove mermaid tails from silicone one at a time by separating silicone from edges of tail. (Do not turn tails over on a flat surface to pop them out or you will break your tails.)
  5. Microwave white candy melts or chocolate chips and 1 to 2 teaspoons oil in 30 second intervals, stirring often, just until fully melted. Repeat with turquoise candy melts.
  6. To make aqua, stir together 2/3 cup turquoise and 2/3 cup white chocolate.
  7. In small glass dish, swirl a smaller amount of aqua chocolate and white chocolate to create marble effect.
  8. Line a large baking sheet with a silicone baking mat, parchment paper or foil.
  9. Dip jumbo marshmallows 1/3 or 1/2 of the way into chocolate, tipping to the side to create waves.
  10. Gently shake off excess chocolate.
  11. Immediately sprinkle with nonpareils and graham cracker crumbs.
  12. Place jumbo marshmallow on lined baking sheet.
  13. Add one mermaid tail to front of dipped marshmallow, holding for at least 15 seconds or until the chocolate can support the weight.
  14. Add star sprinkles if desired.
  15. Repeat steps with remaining marshmallows, adding additional spoonfuls of white chocolate to aqua chocolate as you go. Heat chocolate in microwave for a few seconds if it starts to get too thick.
  16. Store in airtight container, being very careful with the mermaid tails.
