INGREDIENTS
- 1 cup all-purpose flour
- ¾ cup granulated sugar
- 2 tablespoons unsweetened cocoa powder
- 2 teaspoons baking powder
- ¼ teaspoon salt
- ½ cup milk
- 2 tablespoons melted butter
- 1 teaspoon vanilla extract
For Topping:
- ½ cup brown sugar, packed
- ¼ cup unsweetened cocoa powder
- 1¼ cups hot water
DIRECTIONS
- Step No.1: Preheat and prepare
Preheat your oven to 350°F (175°C). Lightly grease an 8x8-inch baking dish and set it aside.
- Step No.2: Mix the dry ingredients
In a medium bowl, combine flour, granulated sugar, cocoa powder, baking powder, and salt. Stir until evenly mixed.
- Step No.3: Add wet ingredients
Stir in the milk, melted butter, and vanilla extract until the batter is smooth and well blended.
- Step No.4: Spread batter in pan
Pour the batter into the greased baking dish and spread it evenly with a spatula.
- Step No.5: Add the topping
In a small bowl, mix brown sugar and cocoa powder. Sprinkle this mixture evenly over the batter without stirring.
- Step No.6: Pour hot water
Gently pour the hot water over the top. Do not stir. This will create the fudge layer as it bakes.
- Step No.7: Bake the cake
Bake for 35–40 minutes until the top looks set and slightly cracked. The bottom will be molten and saucy.

TIPS FOR SUCCESS
- Don’t Stir the Layers: Pour hot water gently and leave it alone—stirring ruins the self-saucing effect.
- Use Boiling Water: The water must be hot to activate the baking reaction that forms the fudge sauce.
- Serve Immediately: For the best gooey texture, serve while warm straight from the oven with your favourite topping.
- Avoid Overbaking: Take it out when the top is just set—overbaking will dry the fudge sauce.
- Add Espresso Powder: For deeper flavour, mix 1 teaspoon instant espresso powder into the dry ingredients.
- Use a Metal Pan: A glass dish may require a few extra minutes of baking time—metal heats more evenly.
- Check Sauce with Spoon: Gently scoop into a corner to see if the sauce layer formed underneath before removing from oven.
VARIATIONS
- Add Chopped Nuts: Mix in ½ cup chopped walnuts or pecans for texture and a nutty crunch.
- Make it Mocha: Add a teaspoon of instant coffee or espresso powder to deepen the chocolate flavour.
- Spice it Up: Stir in a pinch of cinnamon or cayenne for a warm, spicy twist on the classic version.
- Try Dark Cocoa: Use dark cocoa powder for a more intense, bittersweet chocolate experience.
- Top with marshmallows: Add mini marshmallows before baking for a gooey s’mores-style version.
- Swap Sugar Types: Use all brown sugar for a richer molasses flavour in the cake and topping.
- Make Individual Servings: Divide into ramekins or muffin tins and reduce baking time for personal-sized portions.
SERVING AND STORAGE
Serving
Serve warm with a scoop of vanilla ice cream or whipped cream. The contrast of hot cake and cold topping is divine.
Storage
Store leftovers in the refrigerator for up to 3 days. Reheat in the microwave in short bursts until warm and gooey.

FAQ

Yes, double all ingredients and bake in a 9x13-inch dish. Increase bake time by about 5–10 minutes.
Yes, after adding the hot water, it will look odd—but don’t stir. It will bake into layers naturally.
No, use hot water only. Milk will curdle or thicken and prevent proper sauce formation.
It’s not ideal. The texture changes when thawed, and the sauce doesn’t reheat well from frozen.
