Best pudding cake! This easy hot fudge pudding cake recipe makes a delicious chocolate cake and hot fudge chocolate sauce all in one pan. Plus, it only takes about 30 minutes to make!

Chocolate pudding cake was one of the first cakes that I learned to bake. The recipe was in my junior cookbook, and I thought it was magical the way that the cake came out with a warm chocolate layer covering the moist chocolate cake.
This is an updated recipe with more more chocolate flavor, but it’s still just as quick and easy as the original. Since it only takes about 30 minutes to make, it’s perfect for weeknights and special occasions alike.
Ingredient notes
- Cocoa powder – I use unsweetened cocoa powder.
- Salt – If using unsalted butter, increase the salt to 1/2 teaspoon.
- Milk – Any milk, from skim milk to whole milk, will work. Nondairy milk like almond milk will also work.
- Butter – I use salted butter. If using unsalted butter, increase the total salt to 1/2 teaspoon.
- Brown sugar – Light or dark brown sugar will work.
- Hot water – Hot tap water is fine. There’s no need to use boiling water.
How to make hot fudge chocolate pudding cake
Step 1: Preheat the oven to 350 F. Grease a 2.5 quart baking dish. Set aside.
Top tip >> A 2.5 quart baking dish is a 9×9-inch square baking pan or an 8×11-inch rectangular baking dish.

Step 2: For the cake, whisk together the flour, sugar, cocoa, baking powder, and salt in a large bowl.
Step 3: Stir in the milk, butter, and vanilla. Stir together until smooth.

Step 4: Pour the batter into prepared baking pan.
Step 5: For the topping, whisk together the sugars and cocoa; sprinkle the mixture evenly over the cake batter.

Step 6: Pour the hot water over the top of the cake batter. Do not stir the water in.
Step 7: Bake 25-30 minutes. It should look like a thin layer of baked brownie with hot fudge bubbling up in spots.
Step 8: Take out of the oven, and let stand 15 minutes before serving.

Tips
There are only a couple places where you can go wrong.
First: Don’t stir the water in! The water combines with the topping to form the hot fudge sauce, and there’s no need to stir it in.
Second: You won’t want to overbake or underbake the cake. It should look like a layer of thick hot fudge is bubbling underneath the cooked cake layer.
If you underbake the cake, you’ll have watery sauce. If you overbake it, you’ll lose some of the fudgy sauce.

What to serve with this cake
The cake and hot fudge sauce are delicious on their own. However, it’s also great served with a scoop of vanilla ice cream or a dollop of homemade whipped cream.

Storage
Cover and store any leftovers at room temperature for 2-3 days.

So far this recipe is as close as the one I used to make in 19 70 maybe earlier whenever I was like 14 15 years old! And we called it a hot fudge pudding cake nowadays they call lava cakes! Mine turned out absolutely beautiful! And taste even better than it looks! Thank you, Kim
Kate says
Thank you!
Kathy says
So chocolatey and delicious! I followed the directions but it was very full of liquid. What do you think happened? Thank you
Kate says
It sounds like it just needed to bake for a few minutes longer. The cake goes from a thin liquid to a thicker chocolate sauce in the last few minutes of baking. It should look like there’s a thicker fudge sauce bubbling around the edges when the cake is done. I hope that helps!
Anne says

Hi Kate,
If I substitute the 1/2 cup milk with 1/2 cup nut or soy milk should I make any other ingredient adjustments to ensure the recipe turns out with the same consistency?
Kate says
Hi! I haven’t tested it with this recipe, but when I’ve used nut milk in place of dairy milk, I haven’t had to make any other adjustments to the recipe.
Elizabeth says

Hi Kate just wandering if C is for Cup then T is it for Table Spoon?

Yes, I use c for cup, T for tablespoon, and tsp for teaspoon in my recipes. If you have any other questions, please feel free to ask! =)
