What you need:
2 Cups Peanut Butter
1 1/2 Cups Sugar
2 tsp baking soda
1 pinch salt
1 tsp vanilla
Preheat oven to 350 degrees. Grease cookie sheets.
In a medium bowl, stir peanut butter and sugar together until smooth. Beat in the eggs, one at a time. Stir in baking soda, salt, and vanilla. Roll dough into 1 inch balls and place them 2 inches apart on the prepared cookie sheets. Press a criss-cross on the top using the back of a fork.
Bake for 8-10 minutes. Allow cookies to cool on baking sheet for 5 minutes before removing to a wire rack.
