How to Make It
Let’s get baking with these straightforward steps.
Preheat
Preheat the oven to 350°F (175°C) and grease a 9-inch square baking pan. Set aside.
Whisk
In a medium bowl, whisk the flour, sugar, cocoa powder, baking powder, and salt until well combined.
Combine
Add the milk, oil, and vanilla. Stir with a spatula until the batter is smooth and thick. Transfer to the prepared pan and spread evenly.
Sprinkle
In a separate bowl, mix the white and brown sugars and cocoa powder for the sauce. Sprinkle this dry mixture evenly over the batter in the pan. Do not stir.
Pour
Carefully and slowly pour the just boiled water over the top of the batter. Do not stir.
Bake
Bake for 35-40 minutes, until the center is almost set. The cake should look cooked on top but will be fudgy and gooey on the bottom.
Cool
Remove from the oven and let stand for 10-15 minutes. Then, serve warm, scooping the fudgy sauce from the bottom over each serving. Top with a scoop of vanilla ice cream, if desired, and enjoy!
How to Store It
Fridge: Store in an airtight container for up to 2 days.
Freezer: No, the texture changes after freezing.
Reheat: Microwave for 20-30 seconds until warm.
