1/2 cup (1 stick) unsalted butter, softened
1/2 cup dark brown sugar, packed
1/2 cup granulated sugar
1 cup peanut butter, smooth or chunky
1 egg
1-1/2 cup sifted flour
1/2 tsp salt
1/2 tsp baking soda
1/2 tsp vanilla

Preheat oven to 350 degrees F.

Cream together the butter, brown and granulated sugars. Add the peanut butter and egg; beat well.

In a small bowl, combine the sifted flour, salt and baking soda. Stir with whisk to combine. Gradually stir into butter mixture, mixing well after each addition to blend. Add vanilla and mix well.

Roll dough into 1-inch balls and place on greased cookie sheet about 2-inches apart. Flatten each ball with a fork in a crisscross pattern. Bake for 10-12 minutes or until slightly browned around the edges.
