Dirt cake, also called dirt and worms, is an American cake made from cookies and pudding in combination with other ingredients to create a dessert that has a resemblance to soil or earth. It is made by combining crushed Oreo cookies on top of vanilla or chocolate pudding, and adding gummy candy worms on top. Variations include vanilla wafers, vanilla pudding, whipped cream or Cool Whip, and cream cheese pudding in the recipe.
