Really good recipe from Food Network- I put slightly less flour and just rolled them into balls and barely pressed them with a glass.
1 cup sugar, 1/4 cup additional to roll cookies
1 stick butter, at room temp
1 cup smooth peanut butter
1 tsp vanilla
1/2 tsp salt
1/2 tsp baking soda
1 1/2 cups flour
Preheat oven to 375. Grease a baking sheet. In a large bowl, cream together sugar and butter. Beat in egg to mixture. Mix in pb and vanilla until smooth and creamy. Stir in salt, baking soda and flour until well combined. Roll dough into 1-inch balls and then roll in sugar. Place on baking sheet and flatten with fork. Bake for 12-15 minutes.
