Best ever banana muffins

3 large bananas, mashed
3/4 cup white sugar
1 egg
1 tsp baking powder
1/2 tsp salt
1 tsp baking soda
1 1/2 cups flour
1/3 cup melted margarine

Mash bananas; add sugar and slightly beaten egg. Add melted margarine. Add dry ingredients and mix thoroughly. Put in muffin tins and bake at 375 F for 20 minutes.

(this is just a tip, which I am sure you know, but when my bananas are starting to go too brown and no one will eat them. I throw them in the freezer, then when I make these muffins, or anything calling for bananas, I just defrost those...)
