1 tbsp. baking powder
1/2 tsp. salt
1 cup milk
1 egg, beaten
1 cup water
1/3 cup vegetable oil

Preheat oven to 400°F. Grease a 12 cup muffin pan. Sift flour, sugar, baking powder and salt into a medium bowl; make a well in the center.

Mix milk, egg, water, oil, banana and walnuts in a small bowl. Pour into mixture well.
