1 cup all purpose flour
1 tsp. baking powder
1/4 tsp. salt
5 Tbls. butter
6 Tbls. cocoa powder
1 cup sugar
1 tsp vanilla extract
2 large eggs
1 cup finely chopped nuts (optional)
1/2 cup powdered sugar (for rolling cookies in)
Recipe
In a medium bowl, sift flour, baking powder and salt, set aside.
In a small heavy saucepan, melt butter over low heat, add cocoa, blend well until smooth. Remove pan from heat, stir in sugar until combined (it will be dark brown).
Transfer to a large mixing bowl, add vanilla, then eggs one at a time, stirring well after each addition. Add flour mixture and nuts, mix well.
Cover the dough with plastic wrap, refrigerate until chilled (at least 2 hours). The dough never gets really stiff, but it won't roll into nice balls if it's warm.
Preheat oven to 400 degrees.
Grab a handful of dough, enough for a cookie sheet, leaving the rest in the fridge. Roll each hunk of dough into 3/4" balls, then roll in powdered sugar. It is easier to roll the dough into balls if you coat your hands with powdered sugar (kids love doing this).
Place the cookies on a greased cookie sheet, 2" apart.
Bake cookies for 8 minutes, let cool a minute, then remove from pan.
Store in an airtight container to maintain the soft and chewy texture. If you'd like a crisper cookie, cook a minute longer.
