I have a few molds a cake maker gave me and I was wondering can I use them to bake the sculpey in. This would alleviate the distortion of the clay. I know sculpey bakes at 250 degrees so could these molds handle it?

Snip from the wiki. But always research more.
As a low-taint, non-toxic material, silicone can be used where contact with food is required. Silicone is becoming an important product in the cookware industry, particularly bakeware and kitchen utensils.
Silicone is used as an insulator in heat-resistant potholders and similar items; however, it is more conductive of heat than similar less dense fiber-based products. Silicone oven mitts are able to withstand temperatures up to 260 °C (500 °F), allowing reaching into boiling water.

That's more of the food grade ones you're talking about and is more designed for it with other stuff mixed in. Most of those still become soft and flexible at temp, meaning that it could distort during the baking. Cake molds should work, but I'm not sure if it would work well there since you are also adding more covering to where you want to bake and I'm not sure how the end of it would react there and if it would mess with the process. |

I guess a little piece off the side and see what happens

If the mold can handle the heat, you should be able to do this, but I dunno if I'd want to use the mold to cook with afterwards. Probably be OK with a good scrubbing, but in a world where bacon causes cancer... you can't be too careful.
I'd use some release agent to keep the mold from sticking to the baked poly clay, something as simple as Pam cooking spray would probably work fine.

I was thinking of making floors pieces for dungeons and then I thought I could make them thin like less than 4mm but I am thinking that may make the clay too thin

Poly clay is surprisingly strong. Super Sculpey is significantly stronger than plain Sculpey. I'd just do a few test pieces and find a sweet spot for thickness.

One way to find out, I guess. Take pics, let us know what happens.

Yes, you can bake sulpey and other clays in silicone molds. Ive done it. The clay wont bond with the silicone so demolding is a snap. If you are worried about thin pieces breaking you could always embed a few pieces of wire (paperclip) into the clay before baking. It works kind of like adding rebar to concrete. However, you could always us hot glue in the silicone molds too. You get great detail results, it's faster than baking, it wont crack or break, and it takes paint very well. 2 cents and all that....

If you do use Sculpey, be aware that when it comes out of the oven, it is still very soft, and pliable. It is only after it cools that it hardens. Handle it carefully, after baking, until it cools, and hardens. Sculpey takes acrylic paints very well. It is fun to work with, but it is not inexpensive.
If you plan to work with Sculpey quite a bit, invest in a pasta machine for kneading/softening it, prior to use. While Sculpey is non-toxic, everyone says to use dedicated tools, to avoid food contamination. My wife recently bought a pasta attachment for her blender, and I watched her run home-made pasta through it... I have to get one for Sculpey -- it is just too easy to work the clay to prep it for modelling! Cheers!

Doesn't it stick to the mold or do I have to coat the mold prior to adding the hot glue |

Nope, Hot glue simply wont stick to the silicone.

Thank you Curufin! The hot glue idea is perfect! The first piece had issues with the back of the finished piece being lumpy but laying parchment paper over it and gently rolling over it with a rolling pin worked awesomely!

Hot glue is much cheaper than Sculpey! I wonder just how fine in detail I can go tho...

I've considered the same thing with Hirst Arts molds and Sculpey, because I was part of a Kickstarter where they sold molds that you would fill with Sculpey and then bake. Haven't baked any Sculpey in any of my Hirst Arts molds, but am seriously considering it as I've filled the molds with Sculpey, then carefully de-molded the Sculpey from the Hirst Arts molds and baked it separately. That was a success, even though I lost some detail on some of the pieces!
