• 1/2  cup  chunky peanut butter
• 1/2  cup  butter, softened
• 1/2  cup  granulated sugar
• 1/2  cup  packed brown sugar
• 3/4  tsp  baking soda
• 1/4  tsp  salt
• 1    egg
• 1/2  tsp  vanilla
• 1-1/4  cups  all-purpose flour
• 1/2 cup peanuts

Directions

1. In a large mixing bowl beat peanut butter and butter with electric mixer on medium to high speed for 30 seconds. Add granulated sugar and brown sugar, baking soda, and salt. Beat until combined, scraping sides of bowl occasionally. Beat in egg and vanilla until combined. Beat in as much of the flour as you can with the mixer. Stir in any remaining flour.  Add the peanuts.   Cover and refrigerate dough about 1 hour or until easy to handle.

2. Preheat oven to 375 degrees F. Shape dough in 1-inch balls. Place balls 2 inches apart on an ungreased cookie sheet. Flatten the cookies by making crisscross marks with fork tines, dipping fork in sugar between flattening each cookie. Bake about 8 minutes or until edges are lightly browned. Transfer to wire racks. Cool. Makes about 3 dozen cookies.
