Unbelievable Coconut Creme Cake...HELP

I recently visited Sweetsantafe.com and had the most incredible
coconut creme cake with barvaian creme … they do not ship
these cakes, so I am in search of a clone… HELP

This cake sounds delicious, but I am bit confused by this:

“1 cup of confectioners sugar, sifted after measuring 2 teaspoons of granulated sugar”

“Combine the granulated sugar and water in a small heavy saucepan and bring
to a boil over medium heat, stirring to dissolve sugar.”

Do you know how much granulated sugar?

I see now. It seems like a small amount of granulated sugar, but we will see. Thank you.
