Mermaid Birthday Food

The mermaid birthday table can make the party, especially if it’s kept completely and utterly on theme. Yolandi has done an amazing job with the little details – especially the food. You will notice the adorable food label cards giving each food item a creative Mermaid name. These were made with label stickers, card and super gluing shells on. Here’s some of the fabulous and creative food options you’ll find on the table:
  • ‘Sea stars’ – sandwiches cut out with a star cookie cutter.
  • ‘Sea snails’ – sausage rolls. Puff pastry and mini frankfurters.
  • ‘Under the sea’ – jelly cups with mermaid sprinkles on top.
  • ‘Sea pearls’ – chocolate pearls from Big W
  • ‘Coral’ – twisties
  • ‘Treasure’ – chocolate mermaid coins from Big W
  • ‘Tritons of fruit’ – fruit skewers
  • ‘Cheesecake cups’ – three-ingredient, no-bake cheesecakes
  • ‘Ocean vibes’ – sea-themed cupcakes. These were gluten-free to accommodate some of their little guests.
  • ‘Mystical Munchies’ – The mermaid tail boxes with a colourful mix of coco pops chex inside. These are made with melted nestle white choc melt, coloured with colour mill as its oil based. Mix chex through melted chocolate and then pop in ziplock bag with icing sugar to coat it.

Mermaid Decorations

Let’s not forget the amazing decorations that instantly transform the place (plus, look fabulous in those party photos). There are plenty of decorations throughout this party. Here’s how to recreate it:
  • DIY letterboard – bought from Kmart. Message read: Splish Splash it’s a mermaid bash, Ellie is turning 6 – Let’ Shell-obrate.
  • Gold shell decoration – shell sandpits and gold spray paint from Bunnings. Although the spray paint states it works on plastic – Yolandi had big issues with it instantly peeling and would not recommend it.
  • Real life mermaid – if you’re in Perth, Yolandi highly recommends booking Mermaid Melody – she was absolutely amazing with the kids. They booked her to arrive 15 minutes before the party guests and her daughter loved the surprise and the one-on-one time.
  • Balloon garland –  Yolandi and her husband assembled it the night prior.
  • Blue shimmery curtain backdrop.
  • Turquoise platters – Spotlight.
  • Mermaid white platters – Kmart.
  • Multi-tier cake stand – Kmart
  • Cake stand for cookies – Ikea

Mermaid Party Cake Hack

The stunning Mermaid birthday cake in the middle of the party table is a key feature. The best part, Yolandi made this herself with a cake hack! That’s right, there wasn’t even any baking involved.

Yolandi used 4 Woolworths mudcakes, covered in homemade swiss meringue buttercream, homemade fondant decorations and homemade chocolate mermaid tails.

You can find the mermaid moulds here.

 Mermaid cupcakes

You also can’t look past the gorgeous under-the-water cupcakes that look so sweet and on-theme. These were made with Betty Crocker gluten-free chocolate cake mix with Betty Crocker icing. Now, for the decorating! Yolandi used gluten-free Arnotts Nice Biscuits as sand, with fondant decorations and vegan sprinkles. Shop the shell fondant moulds here.

Mermaid Cookies

Another homemade number! ‘Cookie cuteness’  homemade sugar cookies. Yolandi used the sugar cookie recipe from Adelaide bakes, which costs $10 (sometimes on sale). One of the best investments ever. Super easy and delicious.

  • Cookie cutters bought from Custom Cookie Cutters and Bake My Design.
  • Pink and yellow fondant was pre coloured – pettinice, the other colours Yolandi coloured using colour mill colours.

Party Favours
