Here is a recipe that I have for apple muffins and they are delish. I've made them several times and they are yummy:
Topping
1/2 cup packed brown sugar
1/3 cup flour
1 teaspoon cinnamon
2 tablespoons butter, melted
Batter
2 1/4 cups flour
1 teaspoon baking soda
1/2 teaspoon salt
1 egg
1 cup buttermilk (or use 1 tsp vinegar in 1 cup milk)
1/2 cup butter, melted
1 teaspoon vanilla
1 1/2 cups packed brown sugar
2 cups diced apples
Directions:
Topping-mix all together, until mixture forms crumbs. Set aside
Batter- Whisk together egg, buttermilk, butter, and vanilla. Stir in sugar.
Without mixing, add flour, baking soda, salt and apples. Stir just until combined. Do not over mix. Spoon into muffin cups. Sprinkle with the topping.
Bake at 375 degrees F for 20 minutes or until firm to the touch.
Now, this one, I haven't personally tried, but it sounds delish and I think you can find the recipe for it on pinterest, but, you dice up apples and cook them on the stove with whatever you usually use for pie filling (brown sugar, cinnamon, nutmeg, whatever) until they are tender. Then you use canned cinnamon rolls and I think you can get 3 or 4 of this mini pies out of one roll, but you press the cinnamon bun into a greased muffin pan, fill with apple filling, then put a pie crumb on top (I plan to just use the topping from the above recipe since we all liked it). Then you bake according to the cinnamon bun directions and when they come out, drizzle the icing on top. I think they sound delish and I plan to try them on Thanksgiving morning
