Oreo Dump Cake Ingredients

The great news about making an Oreo dump cake, is that is comes together with very few ingredients. The finished cake is perfect for sharing.

• Oreos: You'll need about 32 cookies to fill a 3-quart baking dish. A 14.3-ounce package of Oreos contains about 36 cookies.
• Sweetened Condensed Milk: For the best texture and flavor, use sweetened condensed milk rather than evaporated milk.
• Whipped Topping: A tub of frozen whipped topping is spread over the Oreo layer in this dessert. You can use full-fat, light, or sugar-free if you'd prefer.
• Chocolate Cake Mix: We loved the rich flavor of Devil's Food cake mix but you could easily use chocolate or fudge cake mix.
• Salted Butter: Pats of salted butter finish this dump cake recipe. Our Test Kitchen recommends using salted butter to balance the sweetness of the filling.
