Preheat oven to 350°F. Line a muffin pan with 12 liners. In a small bowl, mix the flaxmeal and water together, and set aside. In a medium-size bowl, mash the bananas with a fork. Add the soy yogurt, sugar, avocado, and vanilla and mix until combined. Add the flaxmeal and water mixture. In a separate bowl, mix together the flour, protein powder, baking soda, and salt. Stir that into the banana-avocado mixture. Divide the batter between the 12 muffin cups. Now it's time to make the crumb topping. In a small bowl, mix together the brown sugar, flour, rolled oats, and cinnamon. Add the cold Earth Balance and use a fork to mix it into coarse crumbles. Sprinkle a little oat crumble on top of each muffin. Bake for 18-20 minutes, or until a toothpick inserted in the middle comes out dry. Source: Calorie Count
