These squares are extremely sweet; they even overwhelmed a diehard sweet tooth like myself. I baked these up for a group of teenagers, and they did go over well with them. The frosting is very good; I can't wait to try it on a plain cake or, perhaps, banana. Do pour the frosting onto the brownies as soon as possible, as it starts to stiffen very quickly. If I bake this recipe again, I will reduce the sugar in the brownies down to 1 cup, and likely up the cocoa.

I'm going to have to ditto Lennie on this one. These were very sweet! People who like really gooey desserts would love this recipe, but I'm not so into gooey. I'm sending these to work with my husband where I'm sure these brownies will be devoured. The icing is especially good. Overall though, just a little too sweet for me -- and I have quite a sweet tooth. What's fun is that they're made with Coca Cola. UPDATE: I let these brownies sit out overnight and my opinion has changed. I am adding one additional star. These brownies are MUCH better the next day. The icing hardens more, the texture improves, the whole thing just comes together.

Dancer! I am not big on sweets, but my husband LOVED these. Also, I took a plate full of them to MIL's for St. Patty's - they gobbled them up. Thanks for making me look good!!
