In this tutorial you will learn how to make a a bonsai tree cake inspired by Earth Day.

Earth Day will be on the 22nd of April and it is our great pleasure to dedicate this tutorial to a wonderful cause. Serdar created this bonsai tree cake as part of an Earth Day themed cake collaboration named ‘ACTs of GREEN’ organised by Zawadi Parizek from the United Nations of Sugar Art. Award winning sugar and pastry artists from all around the world have volunteered their time, talent and materials to create edible showpieces with the hope of raising awareness for the preservation of our planet and the importance of Reduce, Reuse, Recycle as well as donations for National Geographic Society. We are proud to be part of such a great cause and look forward to seeing all the amazing creations in the collaboration.

If we would all look after our Earth like a bonsai tree gardener looks after a bonsai tree, the Earth would be a much better place. We need to live with nature, not replace it. The tutorial will cover a number of different techniques from how to create a large gravity defying tree, how to achieve a realistic rosewood texture, how to accurately create a map of the world and more!

      Serdar, Hi! Yesterday I watched your master class on creating a cake “bonsai”. C’est formidable! The beauty of all your cakes, it is the wealth of your soul, the purity of thoughts and imagination. I wish you long creative years, health, family well-being. Many thanks from me – Galina from Russia.

      1. GALKA AL says:

        “Bonsai.” It’s beautiful.

    4. Aniko Tal says:

      I’m sorry, “when I use Gumpaste instead of Pastillage” :))) That was the first thing I wanted to write 🙂

    5. Aniko Tal says:

      Dear Yener,

      fantastic cake! Thank you so much for thus Tutorial! I have a question.
      My pastillage isn’t completed for second attempt,
      when I use Pastillage instead of Gum Paste, will succeed that?
      Thank you for tour answer, Ani

    6. Bobbi Ames says:

      Another FANTASTIC work of art! You are so amazing and so very, VERY clever! I learn so much from every one of your videos! You think of EVERYTHING!

    7. Marcus Roberts says:

      Hi
      I have a quick question about the cake board the cake is sat on the one you use as a guide to carve the cake.
      The size of it is it the same size as the template on the print out A or is it slightly smaller?
      I’ve watched the video but you don’t mention a size.
      I want to use the right size as worried if I use template A if it’s to big once it’s ganached and iced it will be to big for the pastillage cut out A.
      Hope that makes sense.
      This is my 1st tutorial with you and I’m loving the way it’s all put together.
      Will be buying more after I’ve played around with this one.
      Keep up the good work.
      Marc

      1. Serdar Yener says:

        Yes, Marcus, It makes sense the board underneath the cake should 1 cm less so it will be just right after ganache and fondant coating. Sorry I missed that.

    8. Diane Trett says:

      Hi, loving the tutorial, thank you and what an amazing work of art! Quick question please. If using buttercream to crumb coat can I use white chocolate to seal it? I would like to make it without ganache in the cake if it’s possible??? Thank you

      1. Serdar Yener says:

        Yes, it is possible but after chocolate, you have to coat the cake with thin buttercream again.

    9. Maristela Coupe says:

      Fantastic! How many people does this cake serve? (if, of course, we decide to cut it)

      1. Serdar Yener says:

        30 portion is quite possible. Thanks

    10. Manya Unusyan says:

      Amazing. Thank you Chef Yeners

    11. Lorraine Smith says:

      Simply WOW!
      What an amazingly artistic creation.
      Remember too to avoid any products that contain palm oil. Everything we do impacts the planet, let’s choose to do the things that benefit it and its inhabitants.
      Thanks for sharing another wonderful cake Serdar.

      Stunning

    13. Lucia Suciu says:

      Beautiful!

    14. Linda clouseau1@videotron. says:

      This is just beautiful! And speaking of earth day, we as cake decorators have our work cut out regarding recycling and protecting this planet. There is so much waste and pollution related to what we do specially using oil-based plastic piping bags and throwing them in the trash after.

    15. Elisabetta says:

      I am looking forward to this one! It looks gorgeous!
