It started out as the Banana Muffin recipe in "Company's Coming Muffins and More"... but I tweaked it a little... easy to double for a crowd.
1 cup all purpose flour
1/2 tsp baking soda
1/2 cup mashed bananas
1/2 cup granulated sugar
1/4 cup vegetable or canola oil
2 Tbsp sour cream
1/2 tsp vanilla
Preheat oven to 400*F.
Mix flour and soda in a medium sized bowl. Make a well in the center.
In another bowl, measure bananas, sugar, oil, egg, sour cream and vanilla. Mix together well.
Pour wet ingredients into the dry ingredients and stir just until mixed.
Fill 8 paper lined or greased muffin cups. Put in oven, then immediately reduce oven temperature to 350* F. Bake for 20 - 25 minutes.
Obviously yields 8 muffins.
