#65   There are 2 layers of croissant dough rolled out on a board. Fold the dough into 3rds. Roll into a square.  Fold into 3rds 3 more times. (a total of 4 times)  

How many layers of croissant dough are there?

Fascinating fact:   August Zang, an Austrian artillery officer, is credited with bringing the croissant to France when he opened his1 own Viennese bakery in Paris. (Some say it was Marie Antoinette who brought the croissant to France…)
