Apple Strudel Muffins

I made some really good apple muffins over the weekend. I think they are just as good as the banana crumb muffins....just with apples. I got the recipe from allrecipes, but I'm going to put it in here with my modifications...

INGREDIENTS
2 cups all-purpose flour
1 teaspoon baking powder
1/2 teaspoon baking soda
1/2 teaspoon salt
1 teaspoon cinnamon
1/4-1/2 teaspoon nutmeg (depending on how much you like nutmeg)
1/2 cup butter
1/2 cup white sugar
1/2 cup brown sugar
2 eggs
1 1/4 teaspoons vanilla
1 1/2 cups chopped apples (I used my food processor and shredded the apples, since I thought it would go over better with the boys. And I used a little more than 1 1/2 cups I think.)

1/3 cup packed brown sugar
2 tablespoon all-purpose flour
1/4 teaspoon ground cinnamon
1 tablespoon butter

DIRECTIONS
Preheat oven to 375 degrees F. Grease a 12 cup muffin pan.
In a medium bowl, mix flour, baking powder, baking soda and salt.
In a large bowl, beat together butter, sugar and eggs until smooth. Mix in vanilla. Stir in apples, and gradually blend in the flour mixture. Spoon the mixture into the prepared muffin pan.
In a small bowl, mix brown sugar, flour and cinnamon. Cut in butter until mixture is like coarse crumbs. Sprinkle over tops of mixture in muffin pan.
Bake 20 minutes in the preheated oven, or until a toothpick inserted in the center of a muffin comes out clean. Allow to sit 5 minutes before removing muffins from pan. Cool on a wire rack.
