1 ½cupsall-purpose flour
½cupwhole wheat flour

1teaspoonbaking soda
1cupbuttermilk
Instructions
Preheat oven to 400º F. Grease 12 standard size muffin pan cups or use paper liners.
Beat together butter and sugar at medium speed until light and fluffy. Add eggs, 1 at a time, beating well after each addition. Beat in bananas until smooth.
Mix together flour, salt, baking powder, and baking soda.
Alternately stir flour mixture and buttermilk into egg mixture until dry ingredients are just moistened.
Stir in nuts and vanilla. Do not overmix batter; it should into be completely smooth.
Spoon batter into prepared pan, filling two-thirds full. Bake until lightly golden, 15 to 18 minutes. Transfer muffin-pan cups to a wire rack to cool slightly. Turn out onto rack. Serve warm.
Notes
I almost always get at least 15 muffins if not the whole 18. Depends on the size of your muffin tin and how full you fill them!
