I am doing a friend's bridal shower soon and to go with her coffee theme i picked up some different coffee cups from the local thrift store. I was going to just bake cupcakes and put them in the cups but thought it would be even easier to bake in the cup itself....

Being that these are all mixed, thrift store finds, I have no idea if they are considered "oven safe".

Has anyone done this before? Know of any ways to tell if this would work < id hate to ruin the cups at the last minute>. I only bought cups that were fairly dense, nothing like a light china teacup feel. I attached a photo of the cups I ahve found... I don't know if that would actually help.

What do you think?

Should be good to go. I bake in all sorts of heat proof ceramics & pyrex...cups, mixing bowls, measuring jugs etc. The only trouble I had was the cake shrunk away from the sides when cool. The gap was a good spot to drizzle some fruity filling. Try a couple ahead a time if possible.

Take a look at this fellow CCer's blog. She made molten chocolate cakes in the mugs. Haven't tried it myself but it looked very decadent.

What a clever idea! I can't wait to see your end results.

It would also be nice to do these in new mugs so that the mugs could be the guests' party favors. (if you were throwing the shower, that is)

I've made cakes in coffee cups before (in my gallery with a box of candy-cake). I bought white oven-safe mugs at BedBathBeyond with a 20% coupon.(The only way to shop there!) They had a nice shape but the mugs aren't anything fancy to look at, since they are just white. Sprayed with a little canola oil spray first and they pop right out. I didn't serve in the mugs, I tried different ways of attaching a handle (parts of choco-covered pretzel).
Good luck!
