Banana Oat Muffins with Sour Cream

Step 1

Preheat oven to 350 degrees F (175 degrees C). Grease 12 muffin cups or line with paper muffin liners.

Step 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.

Step 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.

Step 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.

Step 5

Bake in preheated oven for 25 to 30 minutes, until golden brown and a toothpick inserted into a muffin comes out clean.
