2-layer sheet cake?

Absolutely. Cool both layers completely, out of the pan, on a wire rack. They should be quite firm when cold. Fill them with the bottoms together; i.e., put the bottom layer top side down on your cake board or serving tray, spread filling, and put the top layer top side up on top of the filling.

I use a long cutting board push from one side line up your layers and push slowely. mine line up perfect every time. Just remember slowely.
