- 1/2 cup butter, softened
- 1/2 cup white sugar
- 1/2 cup packed brown sugar
- 1 egg
- 1/3 cup peanut butter
- 1/2 teaspoon vanilla extract
- 1 cup all-purpose flour
- 1/2 teaspoon baking soda
- 1/4 teaspoon salt
- 1 cup rolled oats
- 1 cup semisweet chocolate chips
- 1/2 cup confectioners' sugar
- 1/4 cup peanut butter
- 3 tablespoons milk
- Preheat the oven to 325 degrees F (165 degrees C). Grease a 9×13 inch baking pan.
- In a large bowl, cream together the butter, white sugar and brown sugar until smooth. Beat in the egg, 1/3 cup peanut butter and vanilla. Combine the flour, baking soda and salt; stir into the peanut butter mixture. Finally, mix in the rolled oats. Spread the dough evenly into the prepared pan.
- Bake for 20 to 25 minutes in the preheated oven, or until edges are firm. Remove from the oven and sprinkle the chocolate chips in a single layer over the top. Let stand for 5 minutes, then spread to cover. Allow to cool. In a small bowl, mix together the confectioners' sugar, 1/4 cup peanut butter until smooth. Stir in milk one tablespoon at a time until a drizzling consistency is reached. Drizzle over bars when cool. Cut into bars.
