Preheat oven to 400 degrees. Grease two 12 cup muffin pans.
In a mixing bowl combine the oil, butter, molasses, sugar, vanilla, eggs, buttermilk, wheat germ and wheat bran.
In a separate bowl combine the flour, baking soda and powder, salt and cinnamon. Set aside.
Peel and cut apples, then add to wet ingredients along with walnuts. Sprinkle dry ingredients over top and mix just until combined.
Can be covered and kept in refrigerator overnight if desired. Otherwise, fill 20 of the muffin cups and bake for 15 min., or until toothpick comes out clean.
