Continue until you run out of pancakes.
On top, put caramel cream and fresh berries, optionally other decoration if you like?

Notes
Tip! Put a few skewers into the cake if it needs to be transported, so it doesn't slide apart. They can also be left in when the cake is being cut, so the pancakes don't slide. ☺️
