I have a tendency to make banana muffins at least every other weekend. By Sunday I usually have a couple super-ripe bananas around, and nothing makes Sunday morning better than a mountain of muffins and an extra pot of coffee. A couple weekends ago, I found the secret to the best muffins ever: replace the regular boring old milk in your favorite muffin recipe with vanilla soy milk. I swear these were the moistest, tastiest muffins ever. Also put cinnamon in them. Yum!
