1 cup smooth peanut butter (I used a national brand)
3/4 cup brown sugar
1 large egg
1/2 tsp vanilla extract (optional)
1/2 tsp baking soda
1/4 tsp salt
1 cup chocolate chips
Preheat oven to 350F. Line a baking sheet with parchment paper.
In a large bowl, beat together all ingredients until smooth, adding chocolate chips at the end of mixing.
Drop by tablespoonfuls onto prepared baking sheet and flatten slightly with a moistened finger.
Bake for about 10-13 minutes at 350 F, until golden brown at the edges.
Cool on pan before removing to wire rack to cool completely.
