fabulous – years ago a co-worker tipped me off on using a boxed brownie mix (no name, generic, store brand kinds are the best) about 1 cup of Nestle tollhouse morsels, 1 cup of chopped pecans, and I swear it’s as good as any scratch recipe.
 
I don’t deliberatley intend to fool anyone, but when I make them, people just assume it came from an old family recipe.
