Apple Cinnamon Muffins

I found this recipe on Your Cup of Cake's blog and pinned it to Pinterest about 14 weeks ago.  Since then, it has acquired 40 likes and 270 repins and counting.  I suppose one of these days I'll have to bake them and see what all the hype is about.  They do sound delicious though, and the perfect fall muffin!  If anyone tries them, please let me know what you think!

Muffins:

1 ½ cups chopped apple

1 ½ teaspoon lemon juice

1 cup sour cream

½ cup butter, melted and cooled

1 cup sugar

2 eggs

1 ¼ teaspoons vanilla

2 cups flour

3 teaspoons baking powder

½ teaspoon baking soda

½ teaspoon salt

Cinnamon Chips

Topping:

1/3 cup sugar

4 tablespoons flour or graham cracker crumbs

¼ teaspoon cinnamon

2 ½ tablespoons cold butter diced

Directions:

1.     Preheat oven to 375 degrees.

2.    Peel and chop apples (I used granny smith) and then coat with lemon juice.  Set aside. 

3.    In a large bowl, mix sour cream, cooled butter, and sugar until fluffy.  Add eggs and vanilla and mix again.

4.    In a separate bowl, sift together flour, baking powder, baking soda and salt.

5.    Slowly add the dry ingredients to the sugar mixture, do not overmix.

6.   Stir in apples and cinnamon chips. (If you don’t have cinnamon chips you can use 2 teaspoons cinnamon.)

7.    Spoon into muffin liners.

8.   Topping: Mix sugar, flour/graham cracker crumbs, cinnamon and butter until it has reached a crumble consistency. 

9.   Top muffins and bake for 15-18 minutes, or until an inserted toothpick comes out clean.
