1 Tablespoon of egg (take one egg, crack it, mix it up with a fork, measure 1 tablespoon out of it)
¼ teaspoon vanilla
¼ teaspoon baking soda
6 Tablespoons all purpose flour
Instructions
Preheat oven to 350 F.
Mix softened butter, brown sugar, sugar, peanut butter, egg, & vanilla together until smooth. Mix in flour & baking soda. Roll dough into one big ball.
Place on ungreased cookie sheet. Use your hands to gently press the dough ball down into a round circle shape about ¼" thick. Take a fork and lightly run it over the top making 2 lines making a criss-cross shape.
Bake 12-15 minutes or until the edges are just starting to turn a light golden brown.
