Totally drool worthy! I used Splenda for the sugar and Adams (natural) peanut butter and skipped any nuts to keep DH happy. They are so rich and wonderful that I can't say that I think there would be a real benefit in adding nuts. Made just a half amount of the icing and just placed a small dollop in the center of each brownie. Perfectly delicious and rather decadent, whats not to love?

Well, I guess I was kucky to get a couple.. because the gang at work feasted on these at lunch. They were all gone within 10 minutes. I did use fat free butter, smooth peanut butter, and pecans in these. They were very moist and the directions are right to the tee. Came out great !! Made for PRMR tag.
