Instead of butter this recipe uses canola oil and soy milk ... whether it's actually better for you I'm not sure :P
(Got this from http://dulcedoblog.blogspot.com/. Looks yummy but haven't made it yet.)
To make these brownies lower in fat and calories (but still moist and fudgy), some of the eggs and butter were replaced with prune puree.
Helpful hint: Look for the puree in the baby-food or baking section at the grocery store.
