They are indeed quite good, crispy on the outside, soft and chewy in the inside, and they smell wonderful. I like my cookies nice and fat so I use well chilled butter, it keeps the dough cool and won't spread too much in the oven.

Ingredients:
2 c all purpose flour
1/2 tsp baking powder
3/4 tsp ground cinnamon
1/4 tsp salt
3 sticks unsalted butter - yes, three sticks
3 tbsp instant espresso powder or 4 tbsp instant coffee - crushed
1 c confectioners sugar
1/2 c parked light brown sugar
1 1/2 c semisweet chocolate chips

Heat oven to 350 degree. Put granulated sugar in a dish. Scoop out about 1 tablespoon of dough and roll it into the sugar, place it on baking sheet. Bake for 10-12 minutes.
Let the cookies cool on the baking sheet. Enjoy them with a cup of coffee or tea. They are pretty hard to resist.
