1 1/2 cups whole wheat flour
2/3 cup sugar
1/2 teaspoon salt
3 teaspoons baking powder
2 teaspoons cinnamon
1/2 teaspoon nutmeg
1/2 teaspoon allspice
3 heaping tablespoons plain whole yogurt
1/2 cup milk
1 large Granny Smith apple, finely chopped
Preheat oven to 400 degrees.
Quarter apples, slice each quarter in through the middle (like sandwich bread) and then dice length and width-wise, to make 1/2 inch chunks.
Mix all other ingredients in a large mixing bowl.
Blend thoroughly with a hand-mixer.
Use an ice-cream scooper to pour perfect portions into muffin tin.
Bake at 400 degrees for 20-25 minutes.
