4Pour batter into loaf pan. Tap pan twice on counter to level and remove air bubbles. Brush top of batter with melted butter
Sprinkle walnuts on top and press lightly into batter with palm of your hand. Bake 50 minutes or til tester inserted into bread comes out clean. Cool completely in pan on wire rack before slicing.
