In a separate bowl, combine the flour, bran, oats and baking soda. Stir mixture into butter mixture. In a glass baking dishes, press out half of dough mixture into each.
Sprinkle peanut butter candy pieces across top of dough mixture. Cook until done, testing with toothpick, approximately 19 minutes. Cook the rest of the batter, if desired or refrigerate for another time.
