Equipment
- 9 × 13-inch (23 × 33 cm) baking dish
- Medium mixing bowl and whisk (for the pudding)
- Measuring cups and spoons
- Rubber spatula or offset spatula (optional, for smoothing pudding)
- Saucepan or microwave-safe bowl (to melt butter)
- Oven mitts and cooling rack
Ingredients
- 1 box (15.25 oz / ~432 g) chocolate cake mix (dry)
- 1 box (3.9 oz / ~111 g) instant chocolate pudding mix
- 1 cup (170 g) semi-sweet chocolate chips
- 2 cups (480 ml) cold whole milk
- 1/2 cup (1 stick / 113 g) unsalted butter, melted
- Optional: 1/2 cup (≈60 g) chopped walnuts or pecans
Tip: Use quality chocolate chips for deeper flavor; but ordinary semi-sweet chips work beautifully here.
Step-by-step instructions
1. Preheat and prep
Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish with butter or non-stick spray so the edges bubble freely and nothing sticks.
2. Make the pudding layer
In a medium bowl, whisk the instant chocolate pudding mix with 2 cups (480 ml) cold whole milk for about 2 minutes, until it begins to thicken. Don’t worry if it’s still a little loose—instant pudding tightens as it chills and bakes.
Pour the pudding evenly into the prepared baking dish and use a spatula to smooth the surface into an even layer.
3. Add the dry cake mix
Carefully sprinkle the dry chocolate cake mix evenly over the pudding layer. Important: do not stir. The dramatic contrast between layers is how the gooey magic happens.
4. Add the butter and chips
Drizzle the melted butter evenly over the dry cake mix. Try to cover the surface so the cake mix gets some butter throughout (this helps the top turn crisp and the inside stay moist). Sprinkle 1 cup semi-sweet chocolate chips across the top. If using, scatter ½ cup chopped nuts now.
5. Bake
Bake in the preheated oven for 35–40 minutes. You’re looking for bubbly edges and a center that’s set but still slightly wobbly — that wobble means gooey. A toothpick inserted in the center will come out slightly moist, not dry.
6. Rest and serve
Let the dump cake cool for about 15 minutes so it firms up a touch and is easier to scoop. Serve warm—ideal with a scoop of vanilla ice cream, whipped cream, or a drizzle of chocolate sauce.
Tips to guarantee success
- Don’t mix the layers. The contrasting layers (pudding under, cake mix on top) create the molten interior and cakey crust — stirring ruins the texture.
- Cover any dry spots. When drizzling butter, try to reach as much dry mix as possible. If you see pockets of completely dry mix, add a few extra drips—those dry pockets can stay powdery after baking.
- Use cold milk. Instant pudding needs cold liquid to thicken correctly; warm milk will prevent it from setting properly.
- Check early. Ovens vary—start checking at 30 minutes. Remove when edges are bubbling and center is slightly wobbly.
- For extra goo: Reduce cake mix by 2–3 tablespoons and add a heaping 1/4 cup extra chocolate chips inside the pudding layer before sprinkling the dry mix.
- For a crisper top: Use browned butter (cool slightly) instead of plain melted butter—adds nutty depth and a crisp top.
Flavor variations & additions
- Salted caramel twist: Drizzle salted caramel sauce over warm servings.
- Peanut butter swirl: Drop tablespoons of creamy peanut butter on top before baking and swirl lightly.
- Mocha boost: Stir 1–2 tsp instant espresso granules into the milk before whisking into pudding.
- Berry balance: Spoon 1–2 cups fresh raspberries over the pudding layer before adding the cake mix for a bright contrast.
- Nut-free: Omit nuts, or swap for sunflower seed pieces for crunch if you need a nut-free option.
- Gluten-free: Use a gluten-free chocolate cake mix labeled 1:1 and confirm pudding mix is GF.
Storage & reheating
- Room temp: Cover and store up to 2 days at room temperature.
- Refrigerator: Cover tightly and refrigerate up to 4 days. Reheat portions in a microwave (20–40 seconds) until warm, or reheat the whole dish at 325°F (160°C) for 10–15 minutes.
- Freezing: Freeze single portions wrapped in plastic and foil for up to 2 months. Thaw in the fridge overnight and reheat in the microwave or oven. Note: freezing slightly changes the texture (less gooey).

Frequently Asked Questions
Q — Can I use low-fat or plant milk?
A — You can use 2% or skim, but whole milk gives the creamiest pudding and richest flavor. Plant milks vary: oat or soy work best for thickness; almond milk may make the pudding less set.
Q — What if my pudding doesn’t thicken?
A — Instant pudding thickens faster with cold milk and vigorous whisking for about 2 minutes. If it’s still very loose, give it 3–4 minutes; avoid warming it.
Q — My top is dry and powdery after baking — why?
A — That usually means the butter didn’t reach all areas of the dry mix. Next time, drizzle butter more deliberately, or use slightly less cake mix. You can also spoon a couple tablespoons of cold milk over dry spots before baking to help hydrate them.
Q — Can I make this ahead?
A — Yes. Assemble and refrigerate (covered) for up to 24 hours before baking. If chilled, you may need to add 5–8 minutes to baking time.
Q — Is this the same as a cobbler or a lava cake?
A — Not exactly. A dump cake sits between a cobbler and a molten lava dessert: it creates a soft, pudding-like interior with a cakey top that crisps at the edges.
Final nudge
If you’ve ever wanted an almost-foolproof dessert that still feels indulgent and homemade, this Gooey Chocolate Dump Cake delivers. It’s imperfectly perfect—sticky, forgiving, and gloriously chocolatey. Make it for people you love, or keep it all to yourself. Either way, don’t forget the ice cream.
