Oreo Dump Cake

Some desserts just know how to steal the show—effortlessly. That’s exactly what happened the first time I baked this Oreo Dump Cake. I needed a quick, crowd-pleasing treat for a last-minute family movie night. Time was tight, and I didn’t want to mess around with too many steps or ingredients. That’s when I stumbled upon the glorious concept of dump cakes. They’re the easiest kind of baking you can imagine—no mixers, no fuss, no stress. Just dump, layer, and bake.

But I couldn’t go with just any dump cake—I wanted something indulgent, nostalgic, and utterly satisfying. Enter Oreos. Their deep cocoa crunch and creamy center are perfect for transforming a simple dessert into something memorable. The result? A gooey, chocolatey, cookies-and-cream dream that has since become a go-to favorite in my home.

Whether you’re new to baking or just craving something that feels fancy without all the work, this Oreo Dump Cake will pull through every single time. Let’s dive into why this cake belongs in your recipe rotation.

Why I Love This Recipe

There’s a certain kind of magic in recipes that are both stupidly simple and incredibly delicious. That’s why this Oreo Dump Cake is such a winner—it’s a total low-effort, high-reward situation.

The beauty of it is in the layering. You’re not mixing everything into one homogeneous batter like most cakes. Instead, you layer your ingredients like building flavor blocks. Oreos bring the signature crunch and cocoa notes, chocolate pudding adds fudgy richness, sweetened condensed milk adds that luscious texture, and whipped topping gives it a creamy finish that lightens up the intensity just enough.

It’s also wildly versatile. I’ve made this for birthdays, potlucks, date nights at home, and even as a midnight baking treat when I couldn’t sleep. It always satisfies. And because it’s practically foolproof, it’s one of those recipes you can hand off to kids or beginner bakers and still feel confident it’ll turn out delicious.

This Oreo Dump Cake isn’t just good. It’s decadent, layered, rich, and nostalgic. It’s for anyone who grew up sneaking Oreos from the pantry and now wants a grown-up version of that joy baked into a pan of goodness.

Ingredients for Oreo Dump Cake

The best part of this cake is how pantry-friendly it is. You won’t need a long list or anything complicated—just a handful of store-bought staples that you can pick up during one grocery run.

Start with a family-size package of Oreos. You’ll crush most of them but leave a few aside for topping. Then you need chocolate pudding mix—not the instant kind, but the cook-and-serve version. This gives a deeper, fudgier consistency when it bakes into the cake.

Sweetened condensed milk is another key layer. It creates a caramelized richness that melds perfectly with the Oreos. A box of chocolate cake mix (your favorite brand will do) serves as the top crust. And finally, melted butter helps that cake mix turn into a crispy, golden topping, while Cool Whip or any whipped topping adds that soft contrast once the cake is done and cooled.

Here’s everything you’ll need:

• 1 (14.3 oz) package of Oreos, crushed (save 5–6 whole for garnish)
• 2 (3.9 oz) boxes of chocolate pudding mix, cook-and-serve
• 3 cups whole milk (to prepare pudding)
• 1 (14 oz) can sweetened condensed milk
• 1 (15.25 oz) box chocolate cake mix
• ¾ cup unsalted butter, melted
• 1 (8 oz) tub whipped topping, thawed

Optional but delightful: mini chocolate chips, extra crushed Oreos, or even a drizzle of hot fudge before serving.

It’s the kind of ingredients list that makes you want to bake immediately. You don’t need anything fancy, just the commitment to layer it right—and maybe some restraint to wait until it cools a bit before digging in.

How Much Time Will You Need

One of the reasons I keep coming back to this recipe is how little time it demands. From start to finish, it takes just over an hour—but most of that is hands-off baking time.

• Prep Time: 15 minutes
• Cook Time: 40–45 minutes
• Cooling Time: 20–30 minutes (if you want cleaner slices)

So, you’re looking at just over an hour total. But honestly, this is the kind of cake that you can prep while chatting with guests, listening to a podcast, or helping your kids with homework. No sweat involved.

How to Make This Oreo Dump Cake

This is where the magic happens—layer by layer. The key to a perfect Oreo Dump Cake is not overthinking it. Just trust the process, resist the urge to stir, and let your oven do the work.

Step – 1: Crush the Oreos

Start by crushing most of your Oreos. You can toss them in a zip-top bag and use a rolling pin, or pulse them a few times in a food processor. You want coarse crumbs, not powder. Set aside about 5–6 cookies if you’d like to garnish later.

Step – 2: Prepare the pudding

Follow the package directions to cook the pudding (not instant!). Use 3 cups of milk across the two boxes. This pudding will act as the gooey, fudgy base of your cake.

Step – 3: Layer the Oreos

In a 9×13-inch baking dish (lightly greased), spread out your crushed Oreos as the bottom layer. This sets the stage for that delicious cookies-and-cream flavor.

Step – 4: Pour the pudding

Once your pudding is done cooking and still warm, carefully pour it over the Oreo layer. Smooth it out gently with a spatula so it’s even across the surface.

Step – 5: Add sweetened condensed milk

Drizzle the sweetened condensed milk evenly over the pudding. This is your secret sauce for creating a moist, rich texture throughout the cake.

Step – 6: Sprinkle cake mix

Without mixing, sprinkle the dry chocolate cake mix evenly over everything. Make sure it’s distributed in a nice, even layer so every bite bakes properly.

Step – 7: Add melted butter

Pour your melted butter slowly and evenly over the top of the dry cake mix. Don’t stir! Just let it sit as-is and bake into a crisp topping.

Step – 8: Bake

Place your dish in a preheated 350°F (175°C) oven and bake for 40–45 minutes. The top should be slightly firm and crisp when it’s done, but still gooey underneath.

Step – 9: Cool and top

Once it’s baked, let it cool for at least 20 minutes. Then spread your thawed whipped topping over the entire surface and crumble the remaining Oreos on top. Add chocolate chips or fudge drizzle if you’re feeling extra.

Step – 10: Serve and enjoy

Scoop it out while it’s still warm, or refrigerate and slice it cold. Either way, it’s pure Oreo bliss.

Substitutions

One of the best things about dump cakes is how forgiving they are. If you don’t have exactly what the recipe calls for, don’t panic—there are several easy swaps that work beautifully.

If you’re out of chocolate pudding, you can use vanilla or even cookies-and-cream flavored pudding for a twist. Just make sure to stick to the cook-and-serve kind.

No sweetened condensed milk? Try using evaporated milk with a couple of tablespoons of sugar added. Or use a can of dulce de leche if you want an even richer caramel undertone.

You can also swap the chocolate cake mix with devil’s food, fudge marble, or even vanilla cake mix if you’re going for a contrast. And instead of Cool Whip, use homemade whipped cream or even a scoop of vanilla ice cream for a fresh take.

Butter alternatives like margarine or plant-based butter work just fine, too. This is your cake—customize it to your pantry and your cravings.

Best Side Dishes for Oreo Dump Cake

Since this cake is a full-blown dessert on its own, you want to serve it with something that complements without overpowering.

• Vanilla Bean Ice Cream – Adds cool creaminess that pairs perfectly with the warm cake.
• Fresh Strawberries – Their acidity cuts through the richness beautifully.
• Iced Cold Brew Coffee – The bitterness of coffee contrasts the sweet, dense flavors like a dream.

Serving and Presentation Tips

There’s something incredibly satisfying about the way this cake looks when you serve it up warm—the glossy top, the thick layers, and the creamy topping all create a rustic charm that doesn’t need much fuss. Still, a little attention to detail can make it feel like a professionally plated dessert.

To serve this Oreo Dump Cake with a wow-factor, use a large spoon to scoop generous portions into shallow dessert bowls or small glass ramekins. The layers will show more clearly when scooped rather than sliced, which is part of its gooey, indulgent appeal.

Top each serving with an extra dollop of whipped topping or a scoop of vanilla bean ice cream. For texture, sprinkle crushed Oreos on top, or for something more refined, add chocolate curls or a drizzle of warm fudge sauce. You can even add a single whole Oreo on the side of the plate for that bakery-style touch.

If you’re entertaining, consider serving it in individual mason jars or small glass cups—layering a scoop of dump cake, followed by a spoonful of whipped topping, and repeating. It turns a humble dessert into something that looks like it came from a café.

Tips and Tricks to Make This Recipe Better

Every time I make this cake, I learn something new—and over the years, I’ve picked up a few tricks that take it from great to unforgettable.

First, don’t use instant pudding. I’ve said it before, but it’s worth repeating. The texture just doesn’t hold up the same way as cook-and-serve pudding, which bakes into the cake and adds that gooey, brownie-like base.

Use room-temperature ingredients. Cold milk or butter can create uneven baking and won’t spread as nicely. Let your milk and whipped topping sit out for 10–15 minutes before using.

If you want a firmer, sliceable cake, refrigerate it for at least 2 hours after baking and cooling. It firms up into a dense, cake-meets-pudding texture that slices cleanly.

For extra indulgence, mix mini chocolate chips or crushed Oreos into the cake mix before adding the melted butter. It adds pockets of melty goodness and crunch throughout the top layer.

Finally, don’t overbake. Keep an eye on it after the 40-minute mark. You want a crisp top, but a gooey center. That balance is where the magic happens.

Common Mistakes to Avoid

Even a recipe as simple as a dump cake can go off the rails if you’re not careful. Here are a few common mistakes I’ve made—and learned from.

Stirring the layers is the biggest mistake. The magic of a dump cake is in its layers. If you mix them all together, you’ll end up with a muddy mess instead of a cake with texture and depth.

Using instant pudding will give you a thin, watery base that doesn’t hold up. Stick with cook-and-serve.

Pouring butter unevenly can leave dry patches of cake mix. Be sure to drizzle it slowly and cover as much surface area as possible. If you’re worried about dry spots, you can gently tap the pan on the counter to help settle the layers.

Serving too soon can lead to a molten mess (unless that’s what you’re going for!). Let it cool a bit so the layers have time to set.

Forgetting to grease the pan might not ruin the cake, but it makes serving a lot more annoying. A light spray of nonstick cooking spray goes a long way.

How to Store It

Oreo Dump Cake stores incredibly well, which makes it a perfect make-ahead dessert. Once it’s completely cooled, cover the baking dish tightly with plastic wrap or foil, or transfer it to an airtight container.

You can store it in the refrigerator for up to 5 days. The texture will change slightly—it firms up and becomes more like a dense pudding cake—but it’s still delicious.

To reheat, scoop a portion into a microwave-safe bowl and warm it for 20–30 seconds. You can also enjoy it cold—it’s creamy, rich, and tastes almost like a layered chocolate trifle straight from the fridge.

I don’t recommend freezing this cake due to the pudding and whipped topping. It’s best fresh or refrigerated.
