Chocolate Cloud Piece Cake Recipe

Prepare Oven and Pan

Preheat the oven to 350°F (175°C). Grease a 9x13-inch baking pan and line the bottom with parchment paper for easier removal.

Combine Dry Ingredients

In a large bowl, whisk together the all-purpose flour, 1 cup granulated sugar, unsweetened cocoa powder, baking powder, baking soda, and salt until evenly distributed.

Mix Wet Ingredients

In a separate medium bowl, whisk the eggs lightly, then add the whole milk, vegetable oil, and 2 teaspoons vanilla extract. Whisk until combined.

Make a Pourable Batter

Add the wet mixture to the dry ingredients and stir until just combined and no large pockets of flour remain. Slowly pour in the hot water while stirring gently; batter will thin — this yields a moist, tender crumb. Scrape the batter into the prepared pan and smooth the top with a spatula.

Bake the Cake

Bake on the middle rack for 22–26 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs (not wet batter). Remove from oven and allow the cake to cool in the pan on a wire rack for 15 minutes.

Cool Cake Slightly

While the cake is cooling for 15 minutes, prepare the meringue-style topping. The cake should still be slightly warm but not hot when you add the topping; this helps the cloud set to the surface.

Prepare Egg Whites

Place 4 large egg whites in a thoroughly clean, dry mixing bowl. Add the cream of tartar and a pinch of fine sea salt. Using a hand mixer or stand mixer fitted with the whisk attachment, whip the whites on medium speed until soft peaks form.

Add Sugar and Flavor

Gradually add 3 tablespoons granulated sugar, 1 tablespoon at a time, increasing the mixer speed to high after each addition. Continue whipping until glossy, stiff peaks form and the sugar is fully dissolved (rub a small amount between fingers to check for grittiness). Mix in 1 teaspoon vanilla extract.

Top the Cake

Using an offset spatula or large spoon, dollop the meringue mixture onto the warm cake and spread it into an even, cloud-like layer about 1/2–3/4 inch thick. For textural interest, create gentle peaks and swirls in the topping.

Bake to Set the Cloud

Return the cake to the oven and bake at 350°F (175°C) for 6–8 minutes, or until the meringue topping is set and very lightly golden at the highest points. Watch closely to avoid over-browning. Alternatively, for a toasted finish, use a kitchen torch to gently brown peaks after removing from oven.

Cool Completely

Remove the cake from the oven and let it cool completely on a wire rack so the topping firms but remains tender. Chill in the refrigerator for 30 minutes if you prefer a firmer set before slicing.

Dust the cloud with a light dusting of cocoa powder and scatter chocolate shavings and fresh berries over the top or alongside slices. Slice into 12 equal pieces using a serrated knife wiped between cuts for clean edges. Serve chilled or at room temperature.
