I found this recipe in Taste of Home Contest Winning Recipes 2010. I love the cream cheese frosting--this is a great way to doctor up a brownie mix. Thank you for sharing this wonderful simple recipe that looks like you spent all day in the kitchen.
I made these for Christmas. I didn't use the chocolate sauce topping because, after trying a little right after putting the cream cheese topping, they were already pretty sweet. That was the only complaint that I got--they were too sweet. This might be solved with making about 1/2 the frosting mixture or cutting the powdered sugar in half, perhaps. The cashew flavor was a little over powered by the sweetness also. I ate them quite happily, but everyone else could only handle about half a bar. I got the recipe originally from a Taste of Home Cookies and Candies cookbooklet. Thanks for posting!
