Vegan Banana Chocolate Chip Pumpkin Spice Muffins

I lost this recipe on my computer awhile back, and recently found it again. I'm not sure about the original recipe, since I saved it as document with all my changes.

Vegan Banana Chocolate Chip Pumpkin Spice Muffins 

1 cup whole wheat pastry flour
⅔ cup all purpose flour
⅔ cup sugar
1 tsp baking powder
½ tsp baking soda
1 tsp pumpkin pie spice
½ tsp salt
2-3 medium bananas
2 ½ tbsp ground flax seed
5 tbsp water
¼ canola oil
¼ soy milk or other nondairy milk
1 tsp vanilla
⅓ cup mini chocolate chips
⅓ cup regular chocolate chips
Topping
1 tbsp maple sugar
⅛ tsp pumpkin pie spice

*Heat oven to 375°F. Spray a regular-size muffin cup pan with cooking spray, or line with paper baking cups.
*In large bowl, mix the flour, sugar, baking powder, baking soda, pumpkin pie spice and salt.
*In a blender, blend the bananas, flax and water, oil, soy milk and vanilla until smooth. Stir into flour mixture just until flour is moistened. Gently stir in chocolate chips. Don't over mix. Divide batter evenly among muffin cups.
*In small bowl, mix the maple sugar and ⅛ teaspoon pumpkin pie spice. Sprinkle evenly over batter in cups.
*Bake 20 to 24 minutes or until light golden brown and toothpick or knife inserted in center comes out clean. Immediately remove muffins from pan to cooling rack.

Notes:
If you don't have whole wheat pastry flour, you can replace it with more all purpose flour. You can also use all whole wheat pastry flour.

I buy pre-ground flax seed, since I use it a lot and don't want to grind it each time. If you have whole flax seed, grind it in the blender first by itself, and then add the other ingredients.

You can use all regular chocolate chips if you don't have the mini ones. I love using a mix of both, but it's not necessary.

Maple sugar is a granulated form of maple, kind of like regular sugar but with extra tastiness. It's expensive, so if you don't have it and don't want to buy it, use your regular sugar.

You can also beat together the wet ingredients (bananas through vanilla) if you have ground flax seed, but the blender makes it fast and easy.
