Man, oh man, I've been wanting to make something like this for a while. Word of warning, this is pretty text heavy so if you're wanting to skip to the recipe/method because who even has time for that,

For those of you who are unfamiliar with what exactly this cake is - here's a quick rundown. One Piece is a manga series by Eiichiro Oda that started in 1997, and is still running to this day in Weekly Shonen Jump. It's been collected into eighty volumes at last count and it's still going strong. It follows the adventures of Monkey D Luffy, a 'rubber man', and his pirate crew as they sail the seas in search of the fabled One Piece, the former Pirate King's treasure that he left behind; and in this world, there exist things called 'Devil Fruit' which bestow powers on the person who eats them at the cost of them becoming unable to swim. There are different kinds of 'Devil Fruit' - such as ones that turns the user into animals, ones that give the user the ability to control elements or ones that turns the user into rubber. It's all very interesting and you can read more about the series on Wikipedia, go find all eighty volumes at bookstores or watch the first episode on Crunchyroll

The Gomu Gomu no Cake, in all it's glory. While looking
up reference pictures for this entry, someone asked me
whilst looking at the picture above: 'Isn't that the cake
you made?' - One of the best fistpump moments I've ever had. |
This whole thing was first inspired by an article I saw on Kotaku
here about these cakes being available in Korea for a limited run; and I'm a sucker for combinations of some of my favourite things (seen here as anime and baked goods) so my curiousity was piqued. Looking at the pictures, I ran into my first (of many) hurdles. Fondant. It's not that I don't like fondant, per se, but if I can avoid it, I will. I acknowledge that there are many things you can do with fondant that just aren't possible with other icings but I still can't bring myself to cover perfectly good cake with it. Quite possibly, I've just never had good fondant. Which, led me to my second problem - sweetness.
My icing of choice for something like this where I needed to be able to pipe it was buttercream which is basically icing sugar and butter and flavouring. That's it; and for a cake of this size, having to eat that much buttercream in one go would get sickly pretty quickly. In hindsight, cream cheese icing would probably be a good alternative for the outer swirls (maybe I can make the Mera Mera no Mi out of red velvet cake next...hmm); which led me to my third problem - flavours.
The original cake is apparently layers of brownie cake; and that, to me, when coupled with the sweetness of the buttercream, would turn into a mess of sugar. Which although not neccessarily a bad thing was not what I was after.Some of the highlights of my thought process were 'lemon and rosemary cake and earl grey buttercream' and 'coffee and blackberry and whiped cream filling' but I decided to keep it simple, at least for a first attempt, and I went with a coffee flavoured sponge and a chocolate sponge in the hopes that the bitterness of the coffee would balance the sweetness of the sugar. To try and make it more palatable, I decided to go with a coffee buttercream for the inner layers and the outer swirls was a vanilla buttercream. All in all, wasn't bad - was still very sweet but the coffee aftertaste helped.
Once that was all sorted out, the fourth problem reared its ugly head. How do you make a spherical cake without a spherical cake tin? This was the question I asked myself (and Google) and the first, brilliant solution was 'Make two half-sphere cakes, then sandwich together,' on the off chance you have a hemispherical cake tin lying around. I am not one of those people. Looking at the original cake, you can see they've done it in layers so I decided to do something similar. I decided on concentric circles that, once stacked, would magically form a ball shape and got to work. Stand back, we're going to try maths!

Maths. |
I decided to wing it instead and eyeball the cake into submission. First I made the sponges in a baking tray to ensure I got the maximum area (which gives you a bit more wiggle room when cutting). Once that was done, I left them aside overnight to cool. Potentially, you could make this in one day if you start the sponges early enough and you use a fridge to expedite the cooling process. Next, I came across the fifth problem, circles. I don't have that much confidence in my knife ability that I can cut a perfect circle freehand so I found a ramekin, a small bowl, a round yogurt lid and a bigger bowl. Innovation is key!

Does anyone remember that tongue twister about making bitter batter better with better butter? |
|
Make sure you have enough cake for the circle with the biggest circumference! |

Looked good when it was all separate but... |

"Are you making a honeypot cake?" |
Not the most spherical sphere, much to my disappointment. Not to be deterred, I decided to see if a crumb coating would add any improvement. This step's pretty easy, just spread a layer of coffee buttercream in between each layer and build up your cake, then cover the whole thing in a thin layer of icing. Note that it might slide around as you build up the layers, but they can be easily pushed back into place with none the wiser. After the crumb coat had set after about ten minutes in the fridge, it was time to practice my knife skills. I'm sure there's an actual professional way to do this, but I just shaved the sides down until it looked like a sphere. It definitely helped that the cake was hard though, I can only imagine it'd be ten times harder with the layers sliding all over the place - so don't skip the refrigeration step!

Disappointingly enough, the crumb coat did
not magically turn it into a perfect sphere |

After carving, it looked so much better - just use
a sharp knife and whittle that cake! |
Once it's ball-like enough for you, crumb coat with purple icing then in the fridge it goes; then once that's set, you can apply a thicker layer and then it's on to the fun part. Now, I'm a fan of buying things only they're absolutely, positively neccessary and piping bags fall squarely into that category because I figure I can use a ziplock or freezer bag to the same effect more-or-less. However, last Christmas I was blessed with the gift of disposable piping bags, so I decided to treat myself and use one. Straight away, it was a lot easier to pipe but I think I made the hole a bit too big and my swirls didn't turn out quite as planned. So back to the freezer bag I went, and although slightly more cumbersome to hold, I got a better result. Moral of the story - practice does make perfect.
Once you're satisfied with how it looks, pop it back in the fridge and you can get working on the stem. I definitely remembered the stalk being green but didn't feel up to experimenting with food colouring and white chocolate. Fun fact, did you know you can buy pre-coloured icing/chocolate in tubes - and they have flavours? Mind blown that day in the baking aisle. Of course, I didn't have those on me at the time so I went with dark chocolate; and this is where my perfectionist streak metaphorically gut-punched me. The first time I did the stalk, I was pretty happy until I nudged it accidentally in transit to the fridge. Easily fixed, a bit of scraping and I ended up with a far thicker stalk than intended. Third time's the charm, as they say.
Only, not quite so in this case. I took it out of the fridge a few minutes later, only to see that the chocolate had spread out. Maybe it'll look okay when I stick it into the cake, I thought.
It didn't. I spent a good minute looking at it and thinking 'That looks okay,' but, well, the picture doesn't lie. Fourth time lucky! I melted it down and tried again, and failed again.
Third Fifth time's the charm, as they say. With all the focus and steady hands of a neurosurgeon, I finally managed the perfect stalk and I'm so glad I did. In the immortal words of Ron Swanson: "Never half-ass two things. Whole ass one thing."

The crumb coat enables a really clean second layer. |

Yeah, looks just as bad as I remember it looking |
