Banana, Coconut and Chocolate Chip Muffins

We love, Love, LOVE muffins for breakfast, lunch, dinner or snack at our house!  This is a recipe I found through Pinterest originally, but I have modified it just a bit from the original:

Banana, Coconut and Chocolate Chip Muffins
1/2 cup butter, softened
1/2 cup brown sugar
2 eggs
3 overripe bananas
1 tsp vanilla
1-1/2 cups white flour
1/2 cup whole wheat flour
1 tsp baking soda
1/4 tsp salt
1 cup sweetened coconut flakes, divided
1/2 cup mini semi-sweet chocolate chips

Preheat oven to 350 degrees.  Spray muffin pay with cooking spray or line.  In a large bowl, beat together the butter and sugar until creamy.  Add the eggs, bananas and vanilla then continue beating until well combined.  Add baking soda and salt to egg mixture, then add flours until just combined.  Add 3/4 cup of coconut and most of the chocolate chips, mix gently.  Spoon batter evenly into muffin cups.  Sprinkle remaining coconut and chocolate chips on the tops of each muffin. This recipe usually makes 18 muffins.
Bake for about 20 minutes until golden brown.
