                    The maple flavoring in these soft shortbread bars gives a buttery toffee taste without a lot of work. These have been a family favorite for three generations. Ingredients: 
                    
                        
                                                1/2 cup butter, softened  |  
                                                1/2 cup vegetable shortening  |  
                                                1 cup brown sugar  |  
                                                1 egg  |  
                                                1 teaspoon vanilla extract  |  
                                                1/2 teaspoon maple extract  |  
                                                2 cups all-purpose flour  |  
                                                1/2 teaspoon salt  |  
                                                1 (12 ounce) bag chocolate chips  |  
                                                2 tablespoons chopped walnuts (optional)  |  
                                                
                     
                    Directions: 
                    
                        
                            
                                1. Preheat oven to 350 degrees F (175 degrees C). 2. Beat butter and vegetable shortening with brown sugar, egg, vanilla extract, and maple extract until smooth; stir in flour and salt. Lightly press the dough into a 10x15-inch baking dish. 3. Bake until the crust is set and lightly browned, about 15 minutes. 4. Melt chocolate chips in the top of a double boiler over simmering water, stirring frequently and scraping down the sides with a rubber spatula to avoid scorching. Remove crust from oven and spread melted chocolate in a layer on top. Sprinkle with walnuts. Cut bars while still warm; let chocolate set, about 1 hour, before serving.                              |
