Clam-Shell Cookies

These deep-sea snacks are sure to leave a sweet taste in the mouths of your guests, and they are super simple to make!

  1. Purchase a box of plain cookies, or bake them yourself by following a basic recipe online.
  1. Create your buttercream icing by beating icing sugar, butter, and vanilla extract until light and fluffy. 
  1. Separate your buttercream into three separate bowls and add food colouring. We recommend purple, pink and blue for that true mermaid aesthetic!
  1. Pipe the buttercream onto the underside of one cookie, and sandwich another on top. Finish your clams by adding a small, round sweet (yoghurt-covered raisins are a great choice but feel free to get creative!) in the middle to mimic a pearl.

Ocean Water Punch

There is perhaps nothing that screams ‘mermaid party’ more than a bright ocean-coloured drink! This novel idea is sure to be a hit with younger guests, and you only need three ingredients:

  1. Pineapple Juice
  1. Blue Food Colouring
  1. Lemon and Lime Soft Drink, e.g. Sprite

If you want to make an adult version of this drink, consider adding Malibu! 

Blue Jelly in Sand

Who doesn’t love jelly?! Mermify this birthday party staple by making it ocean blue. If you can’t find any blue jelly in the supermarket, use some of the blue food colouring left over from your clam-shell cookies and ocean water punch. Pour into small, shot-sized plastic cups, and leave in the fridge overnight to set. Finish by placing the jelly cups on a bed of crushed biscuits or brown sugar, to mimic sand.

Fruit Crabs

For a healthier treat, try creating these adorable fruit crabs!  

  1. Peel an orange and divide it into segments. 
  1. Cut the orange peel with a knife or scissors, to make the crab’s legs. 
  1. Poke a grape or a blueberry through a cocktail stick and insert it into the orange segment to create an eye. Repeat this step for the other eye.  

And that’s it! Healthy food has never looked so cute! 

Starfish Sandwiches

1. Little yoghurt pots/cups 

2) Vanilla yoghurt with a drop of blue food colouring. 

3) Shark jelly sweets. 

4) Crushed biscuits (to mimic sand). 

You can finish these fin-tastic treats by adding a cocktail umbrella! 

Mermaid Rice Krispie Treats

These gorgeous mermaid Rice Krispie treats are perfect for your under-the-sea party, and they involve no baking whatsoever! 

  1. Buy a box of Rice Krispie squares, or make them yourself if you have more time on your hands. You can do this by combining butter, marshmallows, and Rice Krispies in a saucepan. Mix well, then place the mixture in a lined baking tray. Put the tray in the fridge and leave for 2-3 hours to set, and then cut it into squares. 
  1. Melt some white chocolate in the microwave and add blue food colouring. Alternatively, you could use Wilton Turquoise Candy Melts.  
  1. Dip the Rice Krispie squares into the chocolate, but only halfway. This creates the look of the ocean against the sand!  
  1. Now for the fun part: the decorations! This is your chance to get creative – sweets, sprinkles… you decide. Put your creations back in the fridge to set, and after a few more hours they will finally be party ready!

There are two different options for creating these sweet seaweed treats. You could buy some sour lace sweets, or, for a healthier option, grape skewers also create that under-the-sea effect. Seaweed has never looked quite so appetising!

The Icing on the Cake

Finally, we cannot forget the pinnacle of all party foods… the birthday cake! Whilst we are certainly no Mary Berry, we have seen (and eaten!) dozens of beautiful mermaid cakes over the years. You could create a simple yet effective sandcastle cake, using crushed biscuits to mimic sand and ice cream cones for the turrets. Another option is to buy a plain white cake and decorate it yourself with blue icing, edible pearls, chocolate mermaid tails, and more. But if this all sounds a little over-whale-ming, you can always turn to your local bakery for assistance!
