Step 1: Preheat and Prep

Preheat your oven to 350°F (175°C). Lightly grease a 9-inch square baking dish. While you’re preparing the batter, bring water to a boil in a kettle for the sauce step.

Step 2: Make the Cake Batter

In a medium bowl, whisk together:

• 1/2 cup granulated sugar

• 1 cup flour

• 1/4 cup cocoa powder

• 2 teaspoons baking powder

• 1/4 teaspoon salt

Add in the 3/4 cup milk, 1/4 cup melted butter, and 1 teaspoon vanilla extract. Whisk just until smooth and lump-free.

Pour this batter into the prepared baking dish and smooth it out into an even layer.

Step 3: Add the Fudge Sauce Layer

In a small bowl, stir together the remaining:

• 1/2 cup white sugar

• 1/2 cup light brown sugar

• 3 tablespoons cocoa powder

Sprinkle this dry mixture evenly over the batter in the baking dish.

Now comes the key step: slowly pour the 1-1/4 cups of boiling water directly over the top of the cake. Do not stir. The water will seem to just sit on top—this is exactly what it’s supposed to do.

💡 Baking Magic Tip: As the cake bakes, the batter will rise and the water will sink, creating the fudge sauce underneath.

Step 4: Bake

Place the dish in the oven and bake for 35 minutes, or until the top of the cake is almost set and springs back gently when touched.

Remove from oven and allow to cool for 15 minutes—this helps the pudding layer thicken slightly.
