Combine flour and baking soda.
Beat brown sugar and next 3 ingredients at low speed with an electric mixer 1 minute or until blended. Add peanut butter, and beat 20 seconds or until blended. Add flour mixture, and beat 30 seconds or until well blended. Stir in oats and chopped candy bar.
Drop dough by heaping tablespoonfuls 2 inches apart on an aluminum foil- or parchment paper-lined baking sheet. Dip bottom of a drinking glass in granulated sugar, and flatten mound of dough. Repeat process with remaining sugar and mounds of dough.
Bake at 325° for 15 to 20 minutes or until lightly browned. Cool on baking sheet 2 minutes; remove cookies to wire rack to cool completely.
*2 tsp. egg substitute may be substituted for beaten egg.
Note: For testing purposes only, we used Reese's NutRageous candy bar.
My family loves these cookies. My only complaint is you need to quadrouple the ingredients. It is silly to make only 8 cookies. I use a 10.8oz bag of mini snickers candy bars.
