I admit, I love the microwave. I know there's a lot of debate over how healthy it is but I still enjoy using it. I enjoy making quick desserts in there as it's easier than it sounds. This is a super quick fix for admittted chocoholics such as myself. You can easily substitute ingredients for healthier ones, which is part of the beauty of homemade desserts.
I've used several recipes that were basically the same for brownies but this one I got from Recipezaar. Using this particular recipe, I found that 5 minutes was too long if you like gooey brownies like I do. I will definately go with 4 and a half minutes next time.
