Preheat the oven to 350. Grease a loaf pan or small baking dish with cooking spray and set aside. In a large mixing bowl, combine the dry ingredients and mix well. In a small bowl, whisk the milk, vanilla extract and egg/flax egg. Pour into the dry mixture. Add the melted nut butter (and honey and applesauce for paleo option) and mix very well until a batter is formed. Transfer the batter to the loaf pan or baking dish. Bake for 25-30 minutes, or until golden brown on top and a toothpick comes on clean. Remove from oven and allow to cool completely before serving or frosting, if desired. Combine all the ingredients and using a tablespoon, add dairy free milk until a thick, firm batter is formed. For the cream cheese one, allow to sit at room temperature until it softens. Mix with granulated sweetener and cinnamon.
