                                                1/4 teaspoon ground cinnamon  |  
                                                2 tablespoons butter, chilled  |  
                                                1/4 cup chopped walnuts  |  
                                                
                     
                    Directions: 
                    
                        
                            
                                1. Preheat oven to 350 degrees F (175 degrees C). Grease 12 muffin cups or line with paper muffin liners. 2. Place 1 cup rolled oats in a food processor and process until ground. In a large bowl, combine ground oats with flour, 1 tablespoon rolled oats, chopped walnuts, baking powder, cinnamon and salt. 3. In a separate bowl, cream together the butter and sugar until light and fluffy. Beat in the eggs one at a time, then stir in the banana and vanilla. Stir in sour cream. Mix oat/flour mixture into egg mixture. Spoon batter into prepared muffin pans. 4. To make Topping: In a small bowl, combine 1/3 cup rolled oats, brown sugar, cinnamon. Cut in butter until mixture resembles coarse crumbs; stir in 1/4 cup chopped walnuts. Generously sprinkle muffins with topping. 5. Bake in preheated oven for 25 to 30 minutes, until golden brown and a toothpick inserted into a muffin comes out clean.                              |
