1 cup butter, softened
1 1/2 cups sugar
2 1/4 cups flour
2 tablespoons espresso powder + 1 teaspoon for rolling

Preheat oven to 350 degrees F. Cream together butter and sugar until light and fluffy. Add eggs and vanilla and mix well. Stir in flour, espresso powder, baking powder, and salt and mix until combined.
In separate small bowl, mix coffee and 1 teaspoon of espresso powder. Use a small ice cream scoop to form each ball and roll them in the sugar/espresso mixture. Place on silat lined cookie sheet and flatten slightly. Add a chocolate chip in the middle if you like. Bake 8 to 10 minutes until edges are slightly browned. Whether you eat them hot or cold they are delicious.
