Chewy Chocolate Crackles

These cookies almost beg to be experimented with.  Maybe chocolate chips or nuts or both. Maybe larger scoops and flattened more.  You get my drift?   Just as they are they are tasty cookies, though, so don't think you have to change anything.  I find them a little labor intensive and the recipe in Martha Stewart's "Cookies" is certainly more trouble than it needs to be.  Here is my version:

Ingredients
8 oz bittersweet chocolate
1 1/4 cups all purpose flour
1/2 cup cocoa powder
2 tsp baking powder
1/4 tsp salt
1/2 cup unsalted butter (soft)
1 1/2 cup packed brown sugar
2 large eggs
1 tsp vanilla extract
1/3 cup milk
granulated sugar and powdered sugar for rolling dough

Instructions
Melt chocolate in microwave.  Let cool.  With an electric mixer beat butter and brown sugar 2 to 3 minutes.  Mix in eggs, vanilla, and melted chocolate.  At reduced speed mix in flour, cocoa, baking powder, and salt.  Add milk.  Add nuts, chips, or other optional ingredients.  Divide dough into 3 or 4 parts and refrigerate for at least 2 hours.  Working with one piece of dough at a time, form 1" balls.  Roll first in granulated sugar then in powdered sugar.  Place 2 to 3 inches apart on cookie sheet.  Bake at 350 degrees for 14 minutes.
