Banana Bread with Streusel Topping

Prepare the topping by combining the flour, sugar and cinnamon. Cut in the butter using a pastry cutter or fork. Continue until mixture is crumbly.

For the bread, combine the flour, baking soda, salt, sugar, and cream of tartar in a large bowl. Make a well in the center of the mix. Combine remaining ingredients, except nuts. Add to the dry mix, stirring until well moistened. Stir in the walnuts.

Pour into a greased loaf pan. Sprinkle on the streusel topping. Bake at 350ºF for 45 minutes or until a toothpick inserted comes out clean. Cool for 10 minutes in the pan before inverting onto a wire rack.
