the most delightful treat of the 3rd millenium. A true mud pie consists of a bottom layer of brownie, a middle layer of chocolate coffee-flavored ice cream, and on top is an ever so lite layer of vanilla cream. This tasty dessert is served with whip cream on the side and can be purchased at the always elegant BB King's restaurant in Times Square, New York City.
Golly that Mississippi Mud Pie was the most delicious dessert I have ever had the pleasure to taste!
