Banana Walnut Muffins (so good)

1 cup Splenda
1 1/2 cups flour
1 tsp. baking soda
1 tsp. vanilla
1 stick melted butter
1 tsp. salt
1 egg
4 ripe mashed bananas
1/2 cup chopped walnuts

In a large bowl, mix butter, bananas, egg and vanilla, then add dry ingredients and mix well. Spray your muffin tins with non-stick cooking spray. Bake at 350 until golden brown and toothpick inserted in the middle comes clean. This recipe makes 6 large muffins or 12 regular size. I wrap them individually in plastic wrap and freeze, then pop in the microwave when ready to eat.
