Chocolate Chip Banana Crumb Muffins

I like to make these muffins when I am craving a wholesome dessert, as opposed to the brownies, cupcakes, and chocolate chip cookies, which, although very satisfying taste-wise, often leave my belly grumbling for some more. These muffins are pretty wholesome and filling -- made with bananas, a bit of applesauce, whole wheat (pastry) flour, and walnuts. Of course, I add chocolate chips (did you see the title of this blog?) to make sure no cravings are left unsatisfied.

The original recipe is actually the most popular recipe on allrecipes. Here is my wholesome, chocolate-craving satisfying rendition:

UPDATE: I initially forgot to list one of the most important ingredients: the Chocolate Chips (duh)!! Forgive me, this is my first posting. Clearly, I need practice.

Chocolate Chip Banana Crumb Muffins (adapted from allrecipes)
(Makes 12 muffins)

• 3/4 cups all-purpose flour
• 3/4 cups whole wheat pastry flour
  
• 1 teaspoon baking soda
• 1 teaspoon baking powder
• 1/2 teaspoon salt
• 3 bananas, mashed
• 3/4 cup white sugar
• 1 egg, lightly beaten
• 1/6 cup canola oil
• 1/6 cup applesauce
• 1/2 cup chopped walnuts
• 3/4 cup semi-sweet chocolate chips
  

Crumb Topping

• 1/3 cup packed brown sugar
  
• 2 tablespoons all-purpose flour
  
• 1/8 teaspoon ground cinnamon
• 1/8 teaspoon ground nutmeg
• pinch of ginger
• 1 tablespoon cold butter

1. Preheat oven to 375 degrees F (190 degrees C). Lightly grease 12 muffin cups, or line with muffin papers.
2. In a large bowl, mix together 3/4 cups all purpose flour, whole wheat flour, baking soda, baking powder and salt. In another bowl, beat together bananas, sugar, egg, oil, and applesauce. Stir the banana mixture into the flour mixture just until moistened. Stir in walnuts and chocolate chips. Spoon batter into prepared muffin cups.
3. Crumb Topping: In a small bowl, mix together brown sugar, 2 tablespoons flour, cinnamon, nutmeg, and ginger. Cut in 1 tablespoon butter until mixture resembles coarse cornmeal. Sprinkle topping over muffins.
4. Bake in preheated oven for 18 to 20 minutes, until a toothpick inserted into center of a muffin comes out clean.
