Apple-Cinnamon Crumble Muffins

These muffins were a product of my apple-picking day last weekend and I'm so glad that I made them. They were delicious and I was able to share them (muffins make wonderful gifts!). Don't be afraid of this recipe; I know there are a lot of ingredients, but most of them are dry ingredients that you probably already have in your pantry. This recipe will make about 16-18 muffins. The original recipe can be found here.

Prep Time: 10-15 minutes
Cook Time: 20 minutes

Ingredients
For muffins
Two (2) cups of all-purpose flour
Two (2) cups of finely chopped, seasonal apples -- Your apples should be peeled and cored. Then, use a serrated knife to chop very finely.
One (1) teaspoon of baking powder
1/2 teaspoon of baking soda
1/2 teaspoon of salt
1/2 cup of butter
One (1) cup of granulated sugar
Two (2) eggs, beaten
1 1/4 teaspoons of vanilla extract
1/2 tsp of ground cinnamon
For crumble topping
1/3 cup of light brown sugar
One (1) tablespoon all-purpose flour
1/8 teaspoon of ground cinnamon
1/2 tablespoon of butter

Directions
Preheat your oven to 375F degrees.
In a mixing bowl, mix flour, baking powder, baking soda and salt.
In a separate larger mixing bowl, beat together butter, vanilla, sugar and eggs until smooth. 
Gently mix the chopped apple into the larger bowl.

Slowly and incrementally mix the dry ingredients into the larger bowl.
Spoon the mixture into a greased muffin tin.
In a smaller separate bowl, mix brown sugar, flour, cinnamon and small pieces of butter. This will create a chunky, crumbly topping for your muffins. Sprinkle over the muffin batter.
Bake the muffins for 20 minutes, or until a toothpick inserted in the center of a muffin comes out clean. 
Let muffins cool and enjoy with a hot cup of coffee.
