Black 'n' White Brownies

This recipe is from Laurie Knoke as posted on allrecipes.com. It is similar to Black and White Brownies, but it also includes a frosting. It's a nice "special" brownie, and my husband likes them even though he doesn't like walnuts. I haven't tried omitting them, but I'm sure the results would be fine.
