I bought a Nordic Ware 2D christmas tree cake pan at a yard sale and would like to know if anybody could please tell me how to use it

Is it 2D or 3D? Is it a 2 piece pan that you can put the cake together to get a sculpted cake? If so, then you would either bake both halves and 'glue' them together with frosting, or if there's clips, you fill half of the pan all the way, then clip the two pieces together and bake it and it will rise into the other half. Well, should, I've never used that specific pan. You should be able to find something on the Nordic Ware website on it, or email them for information.
