Waterfall Scene Birthday Cake

I’m not kidding: this is one of the easiest birthday cakes I have made for my kids, and it probably is the most effective too! My eldest daughter turned 14 and she wanted a waterfall cake…so we did a waterfall cake, and it turned out awesome. The entire family was squealing with how awesome it looked. 

Waterfall scene cake - it's easier than you think!

In our house, it’s my husband that decorates the cakes. I do the research with the kids. I shop. I organise. I bake. But he decorates. You see, I am rather impatient when it comes to decorating cakes, and if something goes wrong, I cry and throw a tantrum. I’m not usually like that with projects, but with birthday cakes, I just can’t hack it. But my husband loves doing it, and he is calm, and patient, and methodical and his decorating skills always look better than my efforts. 

What you need

  • Cake board
  • Candy rocks
  • Blue/Green icing
  • Candy flowers
  • Fake trees (20 cents each at a cake shop)

How to make a waterfall cake

1. Make 2 round cakes (whatever flavour), one slightly larger than the other. I used a 24 cm and a 29 cm size.

2. Allow cakes to cool completely. I make the cakes before hand, and then freeze until I’m ready to use. This helps with applying icing. For this process, double wrap cakes in Glad Wrap and carefully place flat in the freezer. Thaw for half an hour before you want to decorate/shape.

3. Trim the top of the cakes with a secreted knife so they are flat. Place the larger cake on the cake board, and then place the smaller cake on top, not in the centre; place it flush against the back of the larger cake.

4. Make a pool in the centre of the top of the cake with blue icing. Then create a waterfall line down the front of the cakes and on to the cake board.

5. Next ice the rest of the cake with green icing.

6. Then it’s the fun part! Sticking on all the elements!  

I found candy stones (the small ones) and chocolate rocks (the large ones) at a candy store

You can find candy flowers in a lot of places (even the supermarket)

The trees are from a cake store. They are just plastic and have no base so you can simply push them into the cake. These will be great for play dough and craft once we are done with the cake. I’m already thinking of a Christmas craft idea. They were only 20 cents each.

    This would be awesome for a Tinker Bell party for younger children. Place a few fairies on there and you’ve got a Pixie Hallow cake:)
    Love it!

    Great cake! You could also use lighter blue or white icing to create foamy parts along the waterfall and at the base. Definitely pinning this for later!

    I’m suprised you didn’t cut the cakes and ice the middles…i’ve never seen anyone not do that. Is there a reason you didn’t?
    Nice cake, I may do something similar for my sons cake.

      I did put some icing between the cakes, but there is always so much icing and I like to keep it at a min.
