The best cake in the world: Simple and creamy like mousse


For the Cake:

  • 1 cup all-purpose flour
  • 3/4 cup granulated sugar
  • 1/2 cup unsweetened cocoa powder
  • 1 tsp baking powder
  • 1 tsp baking soda
  • 1/2 tsp salt
  • 2 large eggs
  • 1 cup whole milk (or buttermilk for extra tang)
  • 1/2 cup vegetable oil
  • 2 tsp vanilla extract
  • 1 cup boiling water

For the Whipped Topping:

  • 1 cup heavy whipping cream
  • 2 tbsp powdered sugar
  • 1 tsp vanilla extract

Step-by-Step Instructions

Step 1: Preheat Your Oven

Preheat your oven to 350°F (175°C). Grease and flour a 9x13-inch baking pan or line it with parchment paper.

Step 2: Mix Dry Ingredients

In a large mixing bowl, whisk together the flour, sugar, cocoa powder, baking powder, baking soda, and salt until well combined.

Step 3: Add Wet Ingredients

Create a well in the center of the dry ingredients and add the eggs, milk, oil, and vanilla extract. Beat with a hand mixer or whisk until smooth and creamy.

Step 4: Incorporate Boiling Water

Gradually stir in the boiling water. The batter will be thin—that’s perfectly normal! Pour the batter into the prepared pan.

Step 5: Bake

Bake for 30–35 minutes, or until a toothpick inserted into the center comes out clean. Allow the cake to cool completely before assembling.

Step 6: Whip the Topping

In a separate bowl, beat the heavy whipping cream, powdered sugar, and vanilla extract until stiff peaks form. Spread the whipped topping evenly over the cooled cake.

Step 7: Decorate & Serve

Garnish with shaved chocolate, fresh berries, or a dusting of cocoa powder. Slice and serve immediately—or chill for an hour to let the flavors meld.


Tips for Success

  • Don’t Skip the Boiling Water: It may seem strange, but adding boiling water ensures the cake stays moist and tender.
  • Use Quality Cocoa Powder: Opt for Dutch-process cocoa for deeper chocolate flavor.
  • Chill Before Serving: If time allows, refrigerating the cake for an hour enhances the mousse-like texture.
  • Experiment with Flavors: Swap cocoa powder for matcha, coffee, or almond extract for unique variations.
