Learn how to make a cake topper of a couple of seahorses in love and decorate a cake with an underwater theme.

In this tutorial, Chef Yener will take you through all the steps to decorate a 2 tier topsy turvy cake with an underwater theme. Although everything you learn in this tutorial can be used to decorate any sized cake with an underwater theme, not just a 2 tier topsy turvy cake. You will learn how to create seaweed, coral, a sea turtle, decorative waves, sea shells, starfish and seahorses out of pastillage. You will also learn how to assemble some of those elements to make a seahorse couple topper. This tutorial does not cover how to make a mad hatter/topsy turvy cake.

  • I love it! Your work is a great inspiration! Thank you very much for your commitment!

  • I just want to say that I love your videos! I have only been doing cakes since Christmas and I have learned so much from you. I can’t wait to work on things every week. I couldn’t even frost a cake before and now I am making such beautiful things from scratch. Thanks again!

  • What a great tutorial. I made this cake for my friend’s wedding. Bride and groom were astonished! They absolutely loved it. Thanks for continuing to make accessible and achievable cake art.

  • I’m really enjoying this tutorial. However, I don’t have an airbrush. Is there another way that I can achieve the colouring effects? Could I brush on dusts and layer the colour that way? Also, how did you colour the pastillage “coral”? PS You are a wonderful teacher!

      Hi Cathy Blue shade on the cake you can achieve by using clean sponge . Dilute the the colour and apply on the cake with small touches at a time and try to make even as possible. If it is not even take it as texture.Colour on seahorses use little brush do it like water colouring. I mix my pastillage with colour before place in the microwave for the corals. Thanks and good luck. I recommend you to get an air brush. Look at our tools at resources section

  • I have just finished watching this truely gorgeous tutorial. You are wonderful Chef. I hope you are fully recovered from the spider bite. Two years ago I was bitten by a spider all over my face and eyes, it looked just like someone had thrown acid on my face and it was so very painful.
    I will try and make the seahorses by the piping chocolate method so I can combine them with the fish tutorial.I don’t know if it will work in the same way as pressure piping with royal icing. I guess the only way to find out is to try it and see. May be I will not be able to get the marking right. Your advice would be appreciated.
    Stay safe Chef, God bless you too always, thank you for everything you teach us. x

      Hi Strudel I did quite a bit of royal icing piped figurines , it works . Few things I will recommend; pipe in stages and give enough time in between so things are not getting too flat. Do all in white and air brush with light colours next day. Don’t thing about Chinese brush painting, Black ink and chocolate has relation but not royal icing. Good luck

  • Gorgeous! I now have to buy an airbrush because the colour graduations are brilliant.

  • This was the best tutorial I have every seen. You are the greatest. I will have to try this cake

  • Awesome! I like the seahorses and the turtle . Your teaching is very valuable and helps me to create beautiful cakes. I am very happy to be a member for this great website. Thank you so much!

    P.S. I hope you feel better and I am sorry to hear what happened to you.

  • Any idea as to when this will be released? I have a cake coming up and I’d just LOVE to use the seahorses!! Please advise.

    Thank you!

  • I can hardly wait for this one 🙂

  • I’m looking forward to this ……

  • Estoy muy ilusionada y lo espero con emoción, gracias un abrazo.
