Tips:
1. I converted the original weight recipes to us standard volume measurement.
2. I ground regular granulated sugar in a food processor to make extra fine sugar.
3. I added 1 tsp of vanilla extract because the original recipe was too eggy.
4. I used a roasting pan filled with 1” water and put the cake pan on the removable rack.
