This old-fashioned hot fudge pudding cake bakes a tender chocolate cake on top of a rich, gooey fudge pudding. Made from scratch with simple pantry ingredients, it’s the kind of comforting dessert your grandmother might have made.
Chocolate pudding cake is pure nostalgia for many of us. I remember how excited I was when my mom made one, and later I made it for my boys. During the years we ran a year‑round camp and conference center, one of our cooks scaled this to feed hundreds — and it was always a hit.
To make hot fudge pudding cake, spread a thick chocolate cake batter in an 8×8 pan, sprinkle with sugar, brown sugar and cocoa, then pour boiling water over the top without stirring. As it bakes, the cake rises and a fudgy pudding sauce forms underneath.

Hot Fudge Chocolate Pudding Cake
This Hot Fudge Chocolate Pudding Cake is the ultimate comfort dessert — soft chocolate cake with a warm, fudgy pudding underneath. It’s easy to make with pantry staples and consistently pleases a crowd.
Ingredients (example amounts)
- 1 tablespoon butter (room temperature)
- 3/4 cup granulated sugar
- 1 1/2 tablespoons cocoa powder
- 1 cup all‑purpose flour
- 1/4 teaspoon salt
- 1 teaspoon baking powder
- 1/2 cup milk
- For the topping:
- 1/2 cup granulated sugar
- 1/2 cup brown sugar
- 1/4 cup cocoa powder
- 1 1/4 cups boiling water
Instructions
- Preheat the oven to 350°F (175°C) and spray an 8×8 inch baking dish with nonstick spray (or grease it well).
- In a mixer or with a hand mixer, cream the butter and sugar together until the butter is broken into small bits and evenly distributed through the sugar. Scrape the bowl so nothing sticks.
- Sift together flour, cocoa, baking powder and salt. Add the dry ingredients to the mixer in portions, alternating with the milk. Mix between additions until fully combined. The batter will be very thick.
- Spread the thick batter evenly into the prepared pan using a spatula.
- In a small bowl, whisk together the topping: granulated sugar, brown sugar and cocoa powder. Press out any lumps with the back of a spoon and sprinkle the mixture evenly over the batter.
- Carefully pour the boiling water evenly over the top — do not stir. The water will sink through during baking and create the pudding layer beneath the cake.
- Bake for about 30 minutes at 350°F, until the cake top looks set. The center may still be slightly jiggly; that’s the pudding. Let the pan rest a few minutes so the sauce thickens, then serve warm.
Notes
Optional: Stir in 1/2 cup chopped walnuts to the batter before spreading for added texture and flavor.

Step‑by‑Step Tips
- Use a deep dish with handles. A pan with handles or a high‑sided baking dish reduces the risk of boiling water splashing when you move it to the oven.
- Set the dish on a baking sheet. If you’re nervous about pouring hot water, place the baking dish on a cookie sheet with sides and transfer both together to the oven.
- Don’t stir after pouring the water. Leaving the layers undisturbed is what creates the pudding beneath the cake.
How to Serve
The cake is wonderful on its own, but it’s even better with a scoop of vanilla ice cream or a dollop of whipped cream. For extra indulgence, add a drizzle of warm chocolate sauce over ice cream and pudding.
Frequently Asked Questions
Do I stir in the boiling water?
No — pour it evenly over the topping and leave it. The water sinks and creates the pudding layer while baking.
Why is the cake wobbly right out of the oven?
That’s normal. The pudding layer will continue to thicken as it cools — let it rest a few minutes before serving.
Can I add nuts?
Yes. Fold in 1/2 cup chopped walnuts into the batter before spreading it in the pan.
Can I halve the recipe?
Yes. Use a smaller pan and check for doneness a few minutes early.
Can you freeze it?
Yes. Cool completely, seal tightly, and freeze up to six months. Thaw in the fridge overnight and warm slightly before serving for best texture.
