Five ingredients. One dish. Five minutes of prep. This is the laziest, most satisfying chocolate cake you will ever make — and nobody needs to know how easy it was.

Dump everything into the pan, stir lightly, bake, and somehow end up with something fudgy, rich, and deeply chocolatey that people will ask you to make again. That’s the magic of the dump cake.

Why You’ll Love This Recipe

• Five minute prep — No mixing bowls, no electric mixer, no complicated steps. Everything goes straight into the baking dish.
• Fudgy and rich — The pudding mix keeps the inside dense, moist, and almost brownie-like in the center.
• Chocolate chips throughout — Pockets of melted milk chocolate in every single bite.
• Nearly impossible to mess up — The whole method is designed to be foolproof. If you can stir, you can make this.
• Serves a crowd — A 9×13 dish feeds 8 to 10 people generously.
• Reheats beautifully — Just as good the next day, maybe better. Fifteen seconds in the microwave and it’s warm and gooey all over again.

Ingredients

• 1 box chocolate cake mix
• 1 box chocolate pudding mix (dry, not prepared)
• 300ml whole milk (1¼ cups)
• 120ml vegetable or sunflower oil (½ cup)
• 200g milk chocolate chips (1¼ cups)

Step-by-Step Instructions

Step 1: Preheat and Prep

Preheat your oven to 350°F (180°C). Grease a 9×13-inch baking dish well — spray or butter both the bottom and sides.

Step 2: Dump the Dry Ingredients

Add the dry cake mix and dry pudding mix directly into the greased baking dish. No separate bowls needed — this all happens in the pan.

Step 3: Add the Wet Ingredients

Pour the milk and oil directly over the dry ingredients in the dish.

Step 4: Stir — Just Enough

Stir the mixture lightly with a fork or spatula until just combined. Stop the moment you no longer see dry streaks of mix. Do not overmix — a slightly uneven, shaggy batter is exactly right and gives you the best fudgy texture.

Step 5: Add the Chocolate Chips

Scatter the chocolate chips evenly across the top of the batter. Press a few in lightly so they don’t all roll to the edges during baking.

Step 6: Bake

Bake for 35–40 minutes, until the center is set and a toothpick inserted in the middle comes out with moist crumbs rather than wet batter. The edges will be slightly more set than the center — that contrast is what makes this cake so good.

Step 7: Cool Slightly and Serve

Let the cake cool for 10 minutes before serving. Serve warm, straight from the dish, with vanilla ice cream, whipped cream, or a drizzle of chocolate sauce.

Pro Tips

Use the dry pudding mix — don’t prepare it. The dry mix goes straight into the dish. Prepared pudding has too much liquid and will throw off the whole recipe. Dry mix only.

Don’t overmix. A few lumps in the batter are fine. Overmixing activates too much gluten and makes the cake tough instead of fudgy. Stir just until combined and stop.

Check with a toothpick, not by appearance. The top can look set while the center is still underdone. A toothpick with moist crumbs — not wet batter — is what you’re looking for. Start checking at 35 minutes.

Let it cool slightly before cutting. Straight from the oven the center will still be very soft and gooey. Give it 10 minutes and it firms up enough to serve in clean portions. Or don’t wait and just scoop it — both are valid.

Warm it up to serve leftovers. A quick 15–20 seconds in the microwave brings back that fresh-baked warmth and the chocolate chips get gooey all over again.

Variations & Customizations

• Dark chocolate version — Swap milk chocolate chips for dark chocolate and use a dark chocolate or chocolate fudge pudding mix for a more intense, less sweet result.
• Peanut butter swirl — Drop spoonfuls of peanut butter across the top of the batter before baking and swirl lightly with a toothpick. Peanut butter and chocolate is always the right decision.
• Add espresso powder — Stir ½ teaspoon of instant espresso powder into the dry mix before adding the wet ingredients. It deepens the chocolate flavor without making it taste like coffee.
• White chocolate chips — Swap some or all of the milk chocolate chips for white chocolate chips for a sweeter, creamier contrast.
• Mocha version — Replace the milk with strong brewed coffee cooled to room temperature for a rich mocha flavor throughout.
• Add sea salt — A pinch of flaky sea salt scattered over the chocolate chips before baking elevates the whole thing and makes the chocolate flavor pop.
• Top with crushed Oreos — Scatter a handful of roughly crushed Oreos over the batter with the chocolate chips for extra crunch and a cookies-and-cream effect.

Frequently Asked Questions

Why is it called a dump cake?

Because the method is exactly what the name says — you dump all the ingredients into one dish and bake. No separate bowls, no mixer, no technique. Just dump, stir minimally, and bake.

Can I use a different pudding flavor?

Yes. Chocolate fudge and dark chocolate pudding both work really well. You could also try vanilla pudding for a slightly different flavor profile — the cake will still be rich and moist, just a little lighter on the chocolate intensity.

Can I use water instead of milk?

Yes, water works as a substitute. Milk gives a noticeably richer, creamier result, so use it if you can — but water produces a good cake too.

Can I make this ahead of time?

Absolutely. This cake actually stays moist and delicious for days and reheats beautifully. Make it the day before and warm individual portions in the microwave before serving.

Why did my cake come out dry?

Most likely overbaked. Start checking at 35 minutes — a toothpick with moist crumbs is the goal, not a completely clean one. A clean toothpick in a fudgy dump cake usually means it went a few minutes too long.
