Chocolate dump cake is a rich, fudgy dessert made by stirring cake mix and pudding mix with milk right in the baking dish, then topping it with chocolate chips and cold butter before it goes into the oven.

It takes about ten minutes to assemble, bakes in forty, and needs only one dish, so it is one of the simplest ways to get a warm chocolate dessert on the table.

Why This Chocolate Dump Cake Recipe Works

Instant pudding mix added to the cake mix makes the center dense and moist, so the finished cake tastes closer to a molten pudding cake than a plain sheet cake.

Cold butter scattered over the top melts as it bakes and forms a rich, slightly crisp crust over the soft chocolate layer below.

Chocolate chips on top soften into glossy pools, which gives every serving a layer of melted chocolate.

Ingredients for Chocolate Dump Cake

You need a box of chocolate cake mix, a small box of instant chocolate pudding mix, whole milk, cold butter, and semi sweet chocolate chips.
Use whole milk for the richest texture, and keep the butter cold so it stays in small pieces on top of the batter.

Cake mix. It supplies the flour, sugar, and leavening, so no measuring is needed.

Pudding mix. It thickens the batter and keeps the cake moist and dense.

Milk. It hydrates the dry mixes into a smooth batter.

Butter. Cold pieces melt into the surface and create a rich, golden crust.

Chocolate chips. They melt into pockets of chocolate on top.

How to Make Chocolate Dump Cake

1. Heat the oven. Heat the oven to 350 degrees F and grease a nine by thirteen inch baking dish.

2. Mix the dry mixes. Pour the cake mix and pudding mix into the dish and stir them together with a fork.

3. Add the milk. Pour in the milk and stir until just combined, scraping the corners so no dry spots remain.

4. Add the chips. Sprinkle the chocolate chips evenly over the batter.

5. Dot with butter. Scatter the cold butter pieces over the top.

6. Bake. Bake for thirty five to forty minutes until the cake is set and risen, then cool in the dish for ten minutes before serving.

Check the center with a toothpick, and expect a few moist crumbs, since the pudding keeps the center softer than a regular cake.

Spread the butter pieces evenly, because large gaps leave dry patches of cake mix on the surface.

Let the cake rest for ten minutes so the layers set, which makes serving much cleaner.

How to Serve Chocolate Dump Cake

Serve the cake warm with vanilla ice cream or whipped cream, and top it with berries or chocolate syrup. It goes well alongside flourless chocolate brownies and no bake chocolate lasagna on a dessert table. For a frosted option, try creamy chocolate buttercream frosting, or serve it after a meal with lemon blueberry pound cake for contrast. You might also enjoy chocolate hazelnut cake. You might also enjoy blueberry dump cake. Another one to try: peach dump cake.

How to Store and Reheat Chocolate Dump Cake

Cover leftovers and refrigerate for up to four days. Reheat individual portions in the microwave for twenty to thirty seconds until warm and soft. Freeze cooled portions in airtight containers for up to two months and thaw in the refrigerator overnight.

Tips and Variations for Chocolate Dump Cake

Flag the allergens. This cake contains wheat, milk, soy, and eggs from the mixes, so warn guests with allergies and check every package label.

Keep the butter cold. Cold butter bakes into pockets and a better crust than melted butter.

Mix well. Scrape the corners and bottom of the dish so no dry mix is left.

Use a glass dish. Glass or ceramic gives even heat for a set center.

Add toppings. Chopped nuts or peanut butter chips are good swaps, and adjust the salt to taste if you add salted nuts.

Cool slightly. The cake sets as it rests, which makes it easier to cut.

Try a dairy free version. Use unsweetened almond milk and a plant based butter stick.

Check trusted guidance. For safe storage of leftover desserts, read the Purdue Extension guide to storing leftovers.

Cake mix boxes vary in size between product lines, so if your box is smaller than fifteen ounces, add an extra spoonful of milk and check the cake five minutes early.

This dessert is flexible, and you can use a different cake mix flavor or swap the chips for caramel bits to create a new version each time.
