Makes 12 large or 24 small muffins.
Preheat oven to 375. Grease muffin tins.
Mix in a large bowl:
1 cup all purpose flour
3/4 cup whole wheat flour
1/4 cup sugar (you may substitute honey, but add to liquid ingredients below)
2 tsp. baking powder
1/2 tsp. salt
(1/4 cup chopped nuts)
Mix in a different bowl:
1 cup plain, non-fat yogurt
2 Tbsp. milk
(1/2 cup fruit: mashed bananas, chopped apples, fresh or frozen berries)
Pour the liquid mixture into the flour mixture and combine quickly. Lumps are ok; don't beat this batter or you'll have exceedingly tough muffins. Fill muffin tins about 2/3rds full and bake 20-25 minutes.
