1/2 cup butter, softened
1/2 cup granulated sugar
1/2 cup firmly packed brown sugar
1 large egg
1/2 tsp vanilla extract
3/4 cup all-purpose flour
1/2 tsp salt
1/2 tsp baking powder
1/2 tsp baking soda
1/2 cup quick oats
1 1/4 cups chocolate chunks
Preheat the oven to 350 degrees.
Lightly grease 2 large baking sheets; set aside.
In a large mixing bowl combine the butter, granulated sugar and brown sugar. Beat at medium speed with electric mixer until creamy. Beat in the egg and vanilla.
Into a small bowl sift the flour, salt, baking soda, and baking powder. Add flour mixture to the creamy mixture, beating constantly. Stir in the oats and chocolate chunks.
Spoon dough by tablespoonfuls about 2-inches apart on the prepared cookie sheets. Bake at 350 degrees for 8 to 10 minutes or until lightly browned. Allow cookies to cool 1 minute on the baking sheets. Transfer to wire racks to cool completely.
