If you have a hard time cutting cakes into even
layers (I also don't have a big enough knife), use dental floss instead. Stick toothpicks exactly halfway up the side of a cake layer. Wrap dental floss around cake so floss is snug against the cake and each toothpick. Make sure the floss alternates over the top and the bottom of each toothpick. Cross ends of floss in front of the cake and pull them away from each other to cut cake into even layers.
Carefully separate layers.
