I'm trying to make these hamburger cupcakes. I've Pm'd the person, but just haven't heard back yet. I want the rounded tops, so I'm thinking about baking the batter in a drinking glass I have. It's got a smooth, rounded bottom, that is just about the perfect size. Have you ever heard of "regular glass" shattering in the oven? 350 degrees? I don't know if it's safe to use non-bake glassware? I don't want to cause an accident. Anyone have any experience? Thanks.

You can cut the tops off of cupcakes. That's how I've down it. And, yes, you can bake in glasses or mugs.

good to know!!Thanks

My only concern would be if there happens to be a little air bubble in the glass. Wouldn't it shatter as the air expands?

I'm going to disagree with this. SOME mugs and glasses are oven safe. But MOST are not. Mugs are more likely to be oven safe and may indicate this underneath. Drinking glasses are likely to shatter under the temperature change unless they are made for this purpose, like pyrex.

Yes, a drinking glass will shatter in the oven. Even most glass coffee cups are not meant to go in the oven. Have you thought about using a pyrex type mixing bowl or a stainless steel bowl for the overn?

They have that rounded bottom.

ditto pp

Now that I think about it, no, I agree with the others.

Try baking the burgers in a parchment lined tin can. After it has baked it should just pop out. If not, open the other end and push it through.
Cut the cooled "cake" into thick slices and you will have your burgers.

Well, I do bake in glasses. But it is the thicker, cheap glass you can see often in a school cafeteria here. It has the thickness of a pyrex glass. I am afraid to try thin glass.

Even so, I set it on a round or rectangular pan and manipulate this pan only - set it with this pan in oven, take it on this pan out, cool it still in this pan. Most problems come from quick temperature changes and I hope this way I get little bit of leeway. And should one glass shatter, the pan would still hold the batter and the shards.

Better way would be to make "homemade pan" from alu-foil. Take your glass as form, three or four layers of heavy foil, mold it around for the pan, roll the edge. It is somewhat flimsy, but you can even bake regular sized cake in such pan.
