Martha Stewart Coconut Cloud Cake Ingredients
For the Cake:
- 1 cup sifted cake flour
- 1 1/2 cups superfine sugar
- 14 large egg whites (1 3/4 cups), room temperature
- 1 tablespoon warm water
- 1/2 teaspoon salt
- 1 1/2 teaspoons cream of tartar
- 2 teaspoons vanilla extract
For the Seven-Minute Frosting:
- 3 large egg whites
- 1 1/4 cups sugar
- 5 tablespoons cold water
- 1/4 teaspoon cream of tartar
- 1 teaspoon vanilla extract
For the Topping:
- 3 to 4 cups flaked coconut

How To Make Martha Stewart Coconut Cloud Cake
- Prep oven and dry ingredients: Preheat oven to 350°F. Sift together flour and 3/4 cup sugar four times.
- Whip egg whites: In a stand mixer, beat egg whites and water until foamy. Add salt, cream of tartar, and vanilla; beat until soft peaks form. Gradually beat in remaining sugar until stiff but not dry.
- Fold in flour: Transfer egg whites to a large bowl. Sift dry ingredients over in six additions, folding gently.
- Bake the cake: Pour batter into an ungreased 10-inch tube pan. Smooth the top and run a knife through to remove air bubbles. Bake 35–40 minutes, until golden and springy.
- Cool inverted: Invert the pan and let the cake cool completely for about 1 hour.
- Make the frosting: In a heatproof mixer bowl set over simmering water, combine egg whites, sugar, water, and cream of tartar. Whisk constantly until foamy and sugar dissolves (about 5 minutes).
- Beat frosting: Attach bowl to mixer; beat on high until glossy and stiff, about 7 minutes. Beat in vanilla.
- Assemble the cake: Release cake from pan. Slice off top 1.5 inches and cut a channel in bottom layer. Fill with frosting and sprinkle with coconut.
- Top and finish: Replace top layer, frost entire cake, and cover generously with coconut. Serve immediately.

Recipe Tips

- Can I make it ahead? Yes, bake the cake a day ahead. Frost just before serving.
- Why use an ungreased pan? It helps the cake rise and cling to the pan properly.

What To Serve With Coconut Cloud Cake
- Fresh berries
- Lemon sorbet
- Light tropical cocktails (like piña colada spritz)

How To Store Coconut Cloud Cake
Room Temperature: Best served the same day.
Refrigerate: Store loosely covered for up to 2 days. Bring to room temp before serving.
