Banana Streusel Chocolate Chip Muffins

As Juniper gets older I love to incorporate her in the kitchen as much as I can.  It's usually more stressful and sometimes frustrating but nothing can beat seeing the excitement in her eyes. And when Landon has crazy hours (which has been more frequent lately) I like to have things he can easily grab and eat in the car when he leaves in the early mornings or a quick snack for when he gets home in the early morning, and these banana muffins are perfect for that. They are super light and fluffy. I prefer no chocolate chips because it takes away from the banana flavor but with Landon's request you will most always find chocolate in them.

Streusel Topping
1/2 cup unbleached all-purpose flour
1/4 cup brown sugar
1 tsp. cinnamon
4 tbsp. butter, melted

Muffins
1 1/2 cups unbleached all-purpose flour
1 tsp. baking soda
1 tsp. baking powder
1/2 tsp. salt
3 large, ripe banana, mashed
3/4 cup sugar
1 egg, slightly beaten
1/3 cup butter, melted
3/4 cup semi-sweet chocolate chips, plus 2 tsp. of flour

Directions
1. For the topping, in a medium bowl, mix flour, brown sugar and cinnamon. Add melted butter and mix until crumbly. Leave crumbs the size of peas. Put aside while preparing muffin batter
2. For the muffins, preheat oven to 375 degrees. In a large bowl, combine dry ingredients. Set aside.
3. In another bowl, combine mashed bananas, sugar, slightly beaten egg and melted butter. Mix well. Stir into dry ingredients just until moistened.
4. If you plan on using chocolate chips, put 3/4 cup of chips into a small bowl. Add in 2 tsp. of flour and coat the chocolate chips in the flour, this prevents them from all sinking to the bottom of the muffin. Add to the muffin batter and fold in.
5. Fill greased muffin cups two-thirds full. (Do not use paper muffin cups). Using hands, arrange coarse, pea-sized crumbs over muffin batter.
6. Bake at 375 degrees for 18-20 minutes or until muffins are done. Cool in pan 10 minutes before transferring to a wire rack.
