Directions

Preheat oven to 350°F (175°C). Grease an 8×8-inch baking dish.
In a medium bowl, mix together flour, sugar, 2 tablespoons of cocoa powder, baking powder, and salt.
Stir in milk, melted butter, and vanilla until smooth. Spread the batter evenly in the prepared dish.
In a separate small bowl, combine brown sugar and remaining cocoa powder. Sprinkle this mixture evenly over the batter.
Slowly pour hot water over the top—do not stir.
Bake for 35–40 minutes, or until the top is set but there’s a gooey pudding layer underneath.
Let cool for about 10 minutes before serving. Scoop and serve warm, ideally with vanilla ice cream.

Storage/Reheating

Store leftovers in the refrigerator for up to 3 days.

The sauce may thicken as it chills, but a splash of milk can help restore the texture when reheating.
Freezing is not recommended as the texture may change significantly.

FAQs

How does this cake make its own sauce?

The hot water poured on top dissolves the sugar and cocoa, sinking to the bottom during baking to form a thick fudge sauce beneath the cake.

Can I make this ahead of time?

It’s best enjoyed fresh, but you can prepare the batter and topping ahead. Pour the hot water and bake right before serving.

What kind of cocoa should I use?

Unsweetened natural cocoa powder works best for rich flavor.

Can I make this gluten-free?

Yes, use a 1:1 gluten-free flour blend. Results may vary slightly in texture.

What should I serve with Hot Fudge Pudding Cake?

Vanilla ice cream, whipped cream, or a dusting of powdered sugar complement it well.

Can I double the recipe?

Yes, double the ingredients and bake in a 9×13-inch pan. Add a few extra minutes to the baking time.

Why is my sauce too runny or too thick?

Baking time and water temperature can affect the sauce. Let it sit for a few minutes after baking to thicken slightly before serving.

Can I use a different sugar for the topping?

Brown sugar is best for flavor and moisture, but you can try coconut sugar for a deeper caramel taste.

Can I add mix-ins to the batter?

Yes, chocolate chips, nuts, or even mini marshmallows make great additions.

How do I know when it’s done baking?

The top should look set and cake-like, but when you scoop it, you’ll see a thick fudge layer underneath.

Hot Fudge Pudding Cake is the perfect dessert when you want something rich, chocolatey, and satisfying without needing frosting or fancy ingredients.
