For my son to take to his creche on his third birthday. Lemon sour cream cake filled with raspberry buttercream.

Has anyone else made this cake following Debbie Brown's instructions? There were a few mistakes, the biggest being that she says to bake two 2" tall 8" square cakes, cut them in half and stack. That's four pieces, right? But the instructions after that were for five pieces. By the time I realised it was too late, so I just had to make it up as I went along rather than following her measurements.
