Bren asked for a D20 cake for his birthday. He wasn’t expecting a 3D one, which makes me wonder who he thinks he’s married to…of course I’m gonna try a 3D one. 🙂

Precision is not my strong suit, so this was a struggle from start to finish and this was literally the best I could do. I’m very keenly aware of how derpy it is. But, I dunno, I kinda like it anyway. It’s made with love.

I tried to find cake pans or molds—no dice (pun intended). Think Geek used to sell a small D20 mold but it’s no longer available.

I found this page of somebody else explaining how they made their cake. This kind soul included the template they used to make their mold. I also considered the technique in this video where the person made a round cake and affixed fondant triangles. I decided on the mold because I didn’t want to have to work with fondant.

The person I was copying used roasting pan lids, but I couldn’t find those. I ended up using disposable cookie sheets. I wonder if they were too flexible—each mold I made was a slightly different size. But, I’m also not very good at this type of thing, so maybe I just don’t know how to fold things the same way each time.

I re-used the same mold to try and ensure the halves would be identical, but cake is cake, so they still varied a little. That’s my excuse, anyway. As you can see, they only sort of sat together properly. I did my best to glue them together with frosting and tried my darndest to keep the frosting smooth.

The numbers… ack. I used melted chocolate but I’m a big dummy and did it directly on the cake, so it dripped all over. I should have done the numbers on wax paper and then just stuck the numbers on there when they had cooled. I don’t know what I was thinking. I probably was not.

The cake itself is just a box of yellow cake, made as directed. The frosting is chocolate buttercream I made at home (the stuff in the can is too runny, I think, for a project like this).

Anyway, it’s derpy, lopsided, and we simply do not need to discuss what the back looks like. But it’s not every day you construct icosahedron halves out of a cookie sheet, so overall 10/10 learning experience. And Bren likes it, which is the most important thing (I guess 😉 <3)
