This easy Oreo poke cake recipe starts with a moist chocolate or devil’s-food cake, sweetened condensed milk, fluffy whipped topping, and plenty of crushed Oreo cookies. Bake it in a 9 x 13-inch pan, poke holes through the warm cake, pour in the creamy filling, chill, then finish it with cookies for a simple dessert that serves 12–15 people.
Every bite is soft, rich, and wonderfully creamy, with chocolate cake soaking up the sweet condensed milk and a crisp cookie topping adding contrast. Prep takes 15–20 minutes, baking takes 30–35 minutes, and the cake needs at least 1 hour to chill, making the total timing about 2 hours 45 minutes.

Oreo poke cake is the kind of dessert that looks festive without requiring complicated decorating skills. The boxed cake mix keeps the preparation quick, while the filling and topping create the rich, creamy texture people expect from a bakery-style chocolate dessert.
The holes are the secret to its soft center. Sweetened condensed milk travels through the cake, giving each forkful a moist, sweet chocolate flavor instead of leaving the filling only on the surface.
- Easy preparation: The cake batter comes together in one bowl.
- Party-friendly size: A 9 x 13-inch pan makes 12–15 servings.
- Make-ahead convenience: The cake needs chilling time, so it can be prepared before guests arrive.
- Kid-approved finish: Crushed Oreos provide a familiar cookie flavor and a little crunch.

Ingredients You’ll Need
Choose a 15.25-ounce box of chocolate or devil’s-food cake mix. Either option works well, and the devil’s-food version usually gives the finished cake a particularly deep cocoa flavor.
Three large eggs, 1/2 cup of vegetable oil, and 1 cup of water create the cake batter. Follow the stated amounts rather than adding extra liquid, since the condensed milk will provide additional moisture after baking.
For the filling, use one 14-ounce can of sweetened condensed milk. This ingredient is thick, sweet, and milk-based, so pour it slowly over the holes to give it time to soak into the cake instead of pooling in one area.
The topping requires one thawed 8-ounce container of frozen whipped topping and 15–20 Oreo cookies. Divide the cookies so most can be crushed for the topping while a few larger pieces remain for a pretty garnish.
Chocolate syrup or hot fudge sauce is optional, but 1/4 cup is enough for a light drizzle. The cake is already sweet and chocolatey without it, so use the drizzle when you want a more dramatic finish.

How to Make It Step-by-Step
Step 1: Heat the oven to 350°F (175°C) and grease a 9 x 13-inch baking pan, making sure to coat the corners well. Combine the cake mix, eggs, vegetable oil, and water in a large bowl, then beat for 1–2 minutes until the batter is smooth.
Step 2: Pour the batter into the prepared pan and spread it into an even layer. Bake for 30–35 minutes, checking the center with a toothpick; it is ready when the toothpick comes out with only a few moist crumbs.
Step 3: Let the baked cake cool for about 10 minutes, so it is warm but not piping hot. Use the handle of a wooden spoon or the end of a large straw to poke holes across the entire cake, spacing them about 1 inch apart.
Step 4: Slowly pour the sweetened condensed milk over the cake, moving back and forth across the surface. Use a spatula or the back of a spoon to spread it toward the edges and guide it into the holes.
Step 5: Refrigerate the filled cake for at least 1 hour, or until it is thoroughly cool. This resting time allows the condensed milk to distribute through the cake while the crumb firms enough to support the topping.
Step 6: Spread the thawed whipped topping evenly over the chilled cake, working gently so you do not pull up the cake underneath. Aim for a smooth layer that reaches all four corners of the pan.
Step 7: Crush most of the Oreo cookies into a mixture of fine crumbs and small pieces. Sprinkle them over the whipped topping, then reserve a few larger pieces to place around the center or along the edges.
Step 8: Drizzle the optional chocolate syrup or hot fudge sauce over the cookie topping. Refrigerate the completed cake until serving, then cut it into 12–15 portions.
Chef’s Tips for the Best Texture
Poke the holes while the cake is still warm, but wait several minutes before pouring in the condensed milk. If the cake is extremely hot, the liquid may collect too quickly and make portions softer than intended.
Space the holes evenly rather than making a few very large openings. About 1 inch apart gives the filling plenty of paths through the cake while leaving enough structure for neat slices.
Pour the condensed milk gradually. A slow pour helps you notice dry areas and spread the filling across them, creating a more consistent texture from corner to corner.
Thaw the whipped topping in the refrigerator before using it. It should be soft enough to spread but still cool, which makes it easier to create a clean, stable layer.
For the best cookie texture, crush the Oreos shortly before serving or sprinkle them on shortly before guests arrive. The crumbs will soften slightly in the refrigerator, while larger pieces retain more crunch.
When planning a seasonal dessert table, this cake pairs nicely with a loaf-style bake such as our pumpkin loaf cake. The contrast between spiced pumpkin and cool chocolate makes the selection feel varied.
Chocolate Pudding Variation
A popular alternative replaces the sweetened condensed milk with instant chocolate pudding. To use this method, whisk one 3.4-ounce box of instant chocolate pudding with 2 cups of cold milk until smooth.
Poke the warm cake as directed, then pour the pudding over the surface and spread it into the holes. Chill until the pudding is set before adding the whipped topping and crushed Oreos.
This variation has a lighter, custard-like chocolate filling and is useful when you prefer a less intensely sweet center. Do not use both the condensed milk and pudding filling together, since the recipe is designed for one filling method.
Serving Ideas and Presentation
Serve the cake directly from the pan for a relaxed family dessert, or cut clean squares for a buffet. A sharp knife wiped between cuts will help the white topping and dark cake look distinct on each slice.
Reserve a few larger Oreo pieces instead of crushing every cookie. Placing one piece on each serving gives the cake an unmistakable cookie-and-cream appearance.
A thin chocolate syrup or hot fudge drizzle is enough to add shine without covering the cookie topping. For a holiday dessert spread, you could also serve a flaky seasonal pastry such as these festive Christmas tree pastries.
Because this is a chilled cake, it is especially welcome at summer gatherings, birthday parties, potlucks, and casual weekend dinners. Keep it cold until dessert time so the whipped topping stays firm.
Storage and Make-Ahead Advice
Cover the pan tightly with plastic wrap or a fitted lid and store the cake in the refrigerator. It keeps well for up to 3–4 days, although the Oreo topping will gradually become softer as it sits.
For maximum crunch, prepare and chill the cake with the whipped topping, then crush and add the Oreos close to serving time. The larger garnish pieces can also be added at the last minute.
This dessert is best served cold and does not need reheating. If it has been stored for several days, check that the topping still looks fresh and keep any leftovers refrigerated.
A sweet dessert like this can be balanced on a larger spread with savory bites, including a little hot pepper jelly served with crackers and cream cheese.
