The creamy layers of the pudding are a simple mixture of butter, sugar, milk, cream cheese and whipped topping, then crushed Oreo cookies are sprinkled on top. This creates an appearance reminiscent of dirt, giving the cake its name.
An Oreo dirt cake requires no baking, and Cooks.com offers a very simple recipe for the cake. The dessert maker should combine 8 ounces of cream cheese with 1/4 cup of butter and 1 cup of powdered sugar. In a separate bowl, he mixes 3 cups of milk with 2 packages of instant vanilla pudding, 1/2 a teaspoon vanilla extract and 12 ounces of Cool Whip or another store-bought whipped topping. Once this is done, he adds the two mixtures together, and layers them in a casserole dish, alternating layers of pudding and crushed Oreos.
The dirt cake is then chilled until the pudding becomes firm and the Oreo pieces soften slightly. The Happier Homemaker recommends chilling the cake for at least two hours. After this period, it is easier to cut the cake into slices.
While the cake can be served in any dish, some dessert makers opt to serve it in a flower pot or with gummy worms on top to emphasize the "dirt" aspect.
