Making realistic polymer clay  cakes is ridiculously fun and easy. Once you learn a few basic tricks you can do pretty much anything you've always wanted to eat (but please, don't eat them!). They make great gifts and dollhouse decorations, and they're sure to surprise your friends.

I'm going to teach you the basics to polymer clay cake making, and a few ideas to decorate them. I'm uploading some of my best cakes for inspiration, but going to your favorite cake store is also highly recommended. This is a very addictive activity, I hope you'll enjoy it and if you need tips please let me know! I'm always glad to help.

This instructable will cover:
  • How to get a realistic translucent cake. Not opaque or chalky.
  • How to make a realistic cake texture.
  • How to decorate your cake with fondant, icing, etc.
  • How to pipe polymer clay.
I'm also including the cutting template and scale conversion table that I made because I hate uneven slices of cake. Please feel free to download it, print it and use it as much as you want, it works for many other projects too. Just please don't redistribute it.

Step 1: Clay and tools


  1. Translucent clay. I use Sculpey III Translucent No. 010
  2. Pale yellow clay. I use Sculpey III Sunshine No. 1274 *
  3. Clay in many colors for fondant, icing, decorations, etc.
  4. Translucent Liquid Sculpey (TLS).
  5. Sculpey Clay Softener (not pictured). If you're going to pipe the clay, softener makes it easier.
* Note: Sunshine was recently discontinued, but there's a color in Premo that's also called Sunshine and it looks pretty much the same. I haven't tried it yet.

  1. A rolling pin or pasta machine.
  2. A round cutter. Mine's diameter is 4 cm.
  3. Blades. For cakes I like to use a tissue blade, razor blade and straight utility knife blade.
  4. Toothpicks and needles. Look for pointy ones! Pointy needles and toothpicks achieve a better texture.
  5. (Not pictured) Icing nozzles. I buy icing nozzles from my cooking store because they're cheap and easy to use, some people prefer to use a clay extruder... but in my opinion, what better way to make realistic pipping than with a real icing nozzle?
