Easy AMAZING Brownies

I was in charge of bringing dessert for our Relief Society dinner tonight and I got home late from studying and taking a test so I had to quickly whip something up with the limited ingredients I had like I always do and I found this AMAZING Brownie recipe on the internet. It was seriously soooo good! I don't ever want to lose it so I am posting the recipe. They are so bad for you, but it's almost worth it. No, it is worth it!
