Step 1

NOTE: 8×3-inch springform pans are great for building this cake so that you can easily remove the cake once it’s been assembled. If you do not have a springform pan, line your cake pan with clear wrap before adding your parchment paper and cake board. You can use the clear wrap to lift your cake out of the pan once it’s assembled and frozen. You want to make your cake layers in the same pan you’ll use for layering the ice cream and cake together so that the cake layers fit in the final pan you use for layering. In lieu of using a cake pan to build the cake, you could also use cake collars, which are easiest.TO MAKE THE CAKE LAYERS:

Step 15

struction-step-15″>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 probably be a little taller than your pan (see example). If you want to, put a cardboard cake circle in the bottom of the pan. If not using a springform pan, you pan put some plastic wrap in the bottom of the pan and up the sides and use it to lift the cake out of the pan when it’s done. If using a clear cake collar, wrap it around the bottom layer of the cake and secure in place with tape.NOTE: You should be using the same 8-inch pan you used for the cake. Not all 8-inch pans are exactly the same size. Your cake needs to fit in this pan.Cut th
