Yes, I do it all the time. In fact, I find it much easier. If you are worried about runny mixture, encase the underside of the tin in foil, which will stop any excess running over your oven.
Can I Use A Spring Form Pan For A Regular Cake?
Yes you can but I suggest using a sheet of wax paper on the bottom so you can remove the cake from pan bottom easier.
Yes, but you need to line it with baking paper/parchment ( not the same as greaseproof paper, but a combined paper of both is suitable). Place a tray underneath as it may drip a little. I use them all the time with no problems.
