For this recipe I've used any number of brownie mixes, but have found that one of the best is Ghirardelli Chocolate 'Triple Chocolate Brownies' mix. Their big 6-lb 4-oz box comes with 5 pouches of mix. Sometimes instead of the extra cup of chocolate chips, I will dice up & add 8-10 chocolate-orange sticks!! The brownies from this recipe are very moist & very richly delicious!
