You've probably seen the tutorials floating around about making cookie bowls for ice cream. One found here. You've also probably seen the failed attempts. Well, my friends and I managed to successfully make cookie bowls (and cookies).
We just made a normal chocolate chip cookie dough. Then, for the bowls, instead of placing the cookie dough completely over the space we wanted it to go, we just barely pushed the cookie dough over the edge, just barely forming a wall for the bowl. That way, when the dough expanded, it wouldn't make a huge mess.
And once the dough was cooked, it went well down the wall and turned into a pretty great cookie bowl.
Have you had much success in making cookie bowls?
