Grease two 8-inch pans (preferably springform pans, see above) and line the bottoms with parchment paper to allow for easy removal. Bake at temperature on box, reducing baking time to about 20 minutes.
Assembling it all:
Line the sides of an 8-inch springform pan with parchment paper. The parchment paper should stick up above the top edge of the pan, since the cake will be a taller than your pan. If you want, put a cardboard cake circle in the bottom of the pan.
