1/2 cup butter

1/2 cup peanut butter
1/2 cup sugar
1/2 cup brown sugar
1 egg
1/2 teaspoon vanilla
1 1/4 cups sifted flour
3/4 teaspoon baking soda
1/4 teaspoon salt

Directions:

• Preheat oven to 375º.  
• Mix first six ingredients.
• Add the rest of the ingredients.
•  Mix well.
•  Roll into balls and press down with a fork dipped in sugar or flour.
•  Bake for 10-12 minutes on ungreased cookie sheet (I usually grease my cookie sheet anyway). Ovens vary so your baking time may be less. Just keep an eye on them.
