I made these over the weekend and they are very yummy, but super sweet. I even omitted the chocolate frosting and swirled in some melted chocolate chips instead and it was still so sweet. I could only eat one at a time, but that's not such a bad thing!

I made these for a pot luck and everyone said they tasted good. Some people absolutely loved them, and others said they were good but too sweet. I thought they were good but too sweet for my taste. I will definately make them again for potlucks. People who enjoy desserts that are very sweet really love these brownies. Thanks for posting this recipe.
