I am making my first angel food cake from scratch. I have a spring form pan with NO tube in it and I have a bundt cake pan. Which would work best?

Can I use my heating core with the spring form pan?

You may be able to use the core in your springform pan. I believe the purpose of the tube pan is so the batter has something to cling to as it rises. There's a lot of air in the batter from the whipped egg whites, so it is a light batter. You still will have to invert the pan when it cools so the cake won't sink. HTH

I would use the tube or bunt pan, it makes a prettier cake. Just my personal preference

I think I am going to give the heating core a chance.

I hope I get this right the first time! No time for a redo!
