I'm not sure where I got this recipe, but it was hand written on a napkin and kept in my recipes. I do remember however, that it is one of the healthiest muffins as it was tucked in my low-calorie baking section. I recently found this again and had to make them over the weekend. OMG, looks like a lot of ingredients, but the texture and tastes was wonderful. A crumbly streusel topping made with a small amount of butter provides a delicious finish. No wonder I kept the recipe. I had to post of Zaar so I wouldn't lose that napkin again.
