Ingredients Overview: Layered Simplicity with Maximum Flavor

Oreo Cookies

The base of the cake. Crushed Oreos soften and meld into the other layers during baking, creating a gooey, chocolate-cookie crust.

• Classic Oreos work best, but you can use Double Stuf for extra richness.

• Crush by hand for a chunkier texture or in a food processor for a finer base.

Sweetened Condensed Milk

Adds richness, sweetness, and gooey texture. It soaks into the cookies and pudding to bind the bottom layers into a fudge-like consistency.

Instant Chocolate Pudding

Adds chocolate flavor and creamy texture. Make sure to use instant pudding (not cook-and-serve), and do not prepare it beforehand—just sprinkle the dry mix.

Whipped Topping (Cool Whip or similar)

Adds a soft, creamy middle layer that balances the richness of the chocolate and adds moisture.

Chocolate Cake Mix

Sprinkled dry over the top, the cake mix bakes into a crispy, brownie-like crust as it absorbs moisture from below and butter from above.

Butter

Melted butter soaks into the cake mix to help it bake into a rich, fudgy topping with crisp edges.

Step-by-Step Instructions: How to Make Oreo Dump Cake

1. Preheat Oven & Prepare Dish

• Preheat oven to 350°F (175°C).

• Lightly grease a 9×13-inch baking dish with non-stick spray or butter.

2. Layer the Crushed Oreos

• Roughly crush 30 Oreo cookies and spread them evenly on the bottom of the dish.

• A few whole chunks are fine—it adds texture.

3. Pour Sweetened Condensed Milk

• Drizzle 1 (14 oz) can of sweetened condensed milk evenly over the crushed cookies.

• Let it settle into the gaps—this becomes the gooey base.

4. Sprinkle Instant Pudding Mix

• Sprinkle 1 packet (3.9 oz) instant chocolate pudding mix directly over the condensed milk layer.

• Do not mix or prepare the pudding—just sprinkle dry.

5. Add Whipped Topping

• Spread 1 (8 oz) container of whipped topping (Cool Whip) gently over the pudding.

• Use an offset spatula or back of a spoon to spread it evenly without disturbing the lower layers.

6. Sprinkle Chocolate Cake Mix

• Evenly sprinkle 1 box (15.25 oz) chocolate cake mix over the whipped topping layer.

7. Add Melted Butter

• Pour 1 cup (2 sticks) unsalted butter, melted over the top of the dry cake mix.

• Try to drizzle as evenly as possible, covering as much dry mix as you can.

8. Bake

• Bake for 40–45 minutes, until the top is set and bubbling around the edges.

• Let it cool for at least 15 minutes before serving so the layers can settle.

Tips, Variations & Substitutions

Tips for Success:

• Don’t stir the layers—dump cakes are meant to be layered and baked untouched.

• Use high-quality cake mix and pudding for the best texture and flavor.

• Let the cake rest after baking to allow the pudding and condensed milk to firm up.

Flavor Variations:

• Cookies & Cream Dump Cake: Use a white cake mix and vanilla pudding instead of chocolate.

• Mint Oreo Twist: Use mint Oreos and chocolate-mint cake mix.

• Peanut Butter Oreo: Add peanut butter chips on top of the cake mix before baking.

• Birthday Cake Version: Use Golden Oreos, vanilla cake mix, and add sprinkles.

Ingredient Swaps:

• Dairy-Free: Use dairy-free sweetened condensed milk, whipped topping, and vegan butter.

• Gluten-Free: Use GF chocolate sandwich cookies and a gluten-free cake mix.

• Homemade Whipped Cream: Replace Cool Whip with 2 cups of stabilized whipped cream if preferred.

FAQ

1. Can I make Oreo dump cake ahead of time?

Yes! You can assemble it ahead and bake just before serving. Or bake fully, then reheat individual slices in the microwave.

2. Do I need to refrigerate leftovers?

Yes. Store in an airtight container in the fridge for up to 4 days. The texture becomes fudgier over time.

3. Can I freeze Oreo dump cake?

Absolutely. Freeze tightly wrapped portions for up to 1 month. Thaw in the fridge and reheat in the oven or microwave.

4. What if I don’t have instant pudding?

You can skip the pudding layer, or use crushed chocolate chips instead. Cook-and-serve pudding won’t work.

5. Can I make this in a slow cooker?

Yes! Layer as directed and cook on LOW for 2–3 hours. The edges will crisp and the middle will stay gooey.

6. Can I use homemade cake mix?

You can use 2 cups of homemade dry chocolate cake mix. Just ensure it contains sugar, flour, cocoa, leavening, and salt.

7. Can I use flavored Oreos?

Definitely! Try Birthday Cake, Peanut Butter, or Mint Oreos for fun twists.
