ooey gooey – mississippi hazelmud tart

Mississippi Mud desserts usually fall into two camps: a pie with ice cream or pudding filling; or a cake/brownie. Either way, the result is intensely chocolate, rich in texture, and sublimely decadent—all the while resembling the mud of the Mississippi riverbanks.

You can trace the origins of Mississippi Mud Pie back to World War II and its southern roots. It was made with simple ingredients widely available in grocery stores—the piecrusts were made from scratch with flour, sugar, butter and eggs. Nowadays, almost all the crusts rely on crushed cookie crumbs from chocolate wafers, such as Oreos minus the filling, to enhance the flavor.

From pastry chefs to home cooks, modern interpretations of the Mississippi Mud Pie feature such ingredients as bourbon, espresso, coffee, marshmallows and nuts. Sometimes it still looks like a pie or a cake—and occasionally you’ll see them in the form of an ice cream sandwich or even deconstructed across a plate. Whatever the shape may be, it’s nothing short of an orgasmic chocolate experience.

For my version of this down-home classic, I’ve combined the best of both the pie and the cake to create the ultimate ooey gooey chocolate mud slide of a dessert. The chocolate wafer crust with the addition of hazelnuts sets the base, and a rich chocolate hazelnut pudding forms the creamy center. Piled high in the center for that messy muddy appearance, cubes of hazelnut brownies sit coated in a luxurious ganache—with just a few chopped hazelnuts sprinkled on top to clue you in on the choice of nuts.
