Ingredients

For the Cloud Cake:

  • 6 large eggs, separated
  • 3/4 cup granulated sugar, divided
  • 1 cup all-purpose flour
  • 1/4 cup cornstarch
  • 1 teaspoon vanilla extract
  • 1/4 teaspoon salt
  • 1/4 cup whole milk
  • 3 tablespoons unsalted butter, melted

For the Nutella Swirl:

  • 1/2 cup Nutella, warmed slightly
  • 2 tablespoons heavy cream
  • 1 tablespoon powdered sugar

For the Whipped Cream Topping:

  • 1 1/2 cups heavy whipping cream
  • 1/3 cup powdered sugar
  • 1 teaspoon vanilla extract

Instructions

Prepare the Pan and Oven:

  1. Preheat oven to 325°F (165°C).
  2. Line a 9×13 inch baking pan with parchment paper, leaving overhang for easy removal.
  3. Lightly grease the parchment with butter or cooking spray.

Make the Cloud Cake:

  1. In a large bowl, whisk egg yolks with 1/2 cup sugar until pale and thick (about 3-4 minutes).
  2. Add vanilla extract, milk, and melted butter to the yolk mixture. Whisk until combined.
  3. Sift together flour, cornstarch, and salt. Gradually fold into the yolk mixture until just combined.

Prepare the Meringue:

  1. In a clean bowl with clean beaters, whip egg whites until foamy.
  2. Gradually add remaining 1/4 cup sugar, beating until stiff, glossy peaks form.
  3. Gently fold 1/3 of the meringue into the batter to lighten it.
  4. Carefully fold in remaining meringue in two additions, being gentle to maintain airiness.

Create the Nutella Swirl:

  1. Mix warmed Nutella with heavy cream and powdered sugar until smooth and spreadable.
  2. Pour cake batter into prepared pan and spread gently.
  3. Drop spoonfuls of Nutella mixture over the surface.
  4. Use a knife or skewer to create swirl patterns through the batter.

Bake:

  1. Bake for 25-30 minutes, until the top is golden and springs back lightly when touched.
  2. The cake should still have a slight jiggle in the center.
  3. Cool completely in the pan.

Make Whipped Cream:

  1. Whip heavy cream, powdered sugar, and vanilla until soft peaks form.
  2. Don’t overwhip – keep it light and airy.

Serve:

  1. Cut into squares and top with whipped cream.
  2. Dust with additional powdered sugar if desired.
  3. Serve immediately for the best “cloud-like” texture.

Tips:

  • The cake gets its “cloud” texture from the light meringue and should be eaten fresh
  • Don’t overbake – a slightly underdone center keeps it fluffy
  • Store leftovers covered in refrigerator for up to 2 days
  • Warm Nutella slightly for easier swirling, but don’t make it too hot or it will deflate the batter
