1 cup butter, softened
1 1/2 cups granulated sugar
1/2 cup firmly packed light brown sugar
1 tablespoon vanilla extract
2 large eggs
3 1/2 cups all-purpose flour
1/2 teaspoon baking soda
1/2 teaspoon salt
1 cup chopped honey-roasted peanuts
1 (4-oz.) semisweet chocolate baking bar, finely chopped
How to Make It
Beat first 4 ingredients at medium speed with an electric mixer until fluffy. Add eggs, 1 at a time, beating just until blended after each addition.
Stir together flour and next 2 ingredients; gradually add to butter mixture, beating just until blended after each addition. Stir in peanuts and chopped chocolate baking bar.
Shape dough into 4 logs (about 2 inches in diameter); wrap each log in plastic wrap. Chill 8 hours to 3 days.
Preheat oven to 350°. Cut each log into 1/4-inch-thick slices; place on parchment paper-lined baking sheets. Bake 8 to 12 minutes or until lightly browned. Remove from baking sheets to wire racks, and cool completely (about 20 minutes).
