"Very good! I took pcronk's advice and sprinkled mini chocolate chips on top instead of the topping. Also used butter-flavored shortening."

"This is one of my favorite recipes! It was in the TOH cookbook received as a wedding gift. SO rich but SO good! Love the dense brownie-like texture. I usually don't put the drizzle on."
