Brownies with Chocolate Buttercream Frosting

These brownies are so and thick and rich. I don't like chocolate, but I can eat a bite, ONE bite, and actually I like them. They do not last 30 minutes in the house! I will have to say that the frosting is the best part. I LOVE frosting, icing, topping or whatever is on top of cookies and cakes! This is one frosting I make quite a bit....it is soooo good, even for me. In fact, this is the frosting I will use for the cake I posted yesterday instead of the caramel frosting.
I like the fact, as well, that you can make them in 1 bowl and don't have to use the mixer..... I am sure you can, I choose not to. As I have said before I look for new recipes and ideas on websites. Chocolate is a favorite of the kids and if I make chocolate I won't eat it...so, win - win situation! Anywhooooo...the Hershey's website is a great tool in looking for kid friendly treats! Yum!
