  • Total Time: 50 minutes
  • Yield: 8 servings 1x

Ingredients

Scale

Cake Ingredients

  • 1 ¾ cups all-purpose flour
  • 1 ½ teaspoons baking powder
  • 1 cup unsweetened coconut flakes
  • 3 large eggs
  • 1 ¼ cups granulated sugar
  • ½ cup milk
  • ⅓ cup sour cream
  • 1 teaspoon vanilla extract

7-Minute Frosting Ingredients

  • 4 large egg whites
  • 1 ½ cups granulated sugar
  • ⅛ teaspoon cream of tartar
  • ½ cup (1 stick) unsalted butter, softened

Garnish (optional)

  • Additional unsweetened coconut flakes, toasted
  • Edible flowers
  • Passion fruit syrup (for drizzle)

Instructions

  1. Prepare the Cake Batter: In a bowl, mix the all-purpose flour, baking powder, and unsweetened coconut flakes. In a separate bowl, whisk together eggs, granulated sugar, milk, sour cream, and vanilla extract until fully combined. Gradually add the dry ingredients to the wet mixture, folding gently to maintain airiness without overmixing.
  2. Bake the Cake Layers: Pour the batter evenly into greased cake pans. Bake at 350°F (175°C) for 25 to 30 minutes or until a toothpick inserted in the center comes out clean. Let the cake layers cool completely before frosting.
  3. Make the 7-Minute Frosting: In a heatproof bowl over simmering water, combine egg whites, granulated sugar, and cream of tartar. Whisk continuously for about 7 minutes until the mixture thickens, becomes glossy, and holds stiff peaks. Slowly add softened butter while beating continuously until the frosting is smooth and fluffy.
  4. Assemble and Frost the Cake: Place one cake layer on a serving plate and spread a generous layer of the 7-minute frosting on top. Repeat with the next layer, then cover the entire cake with the remaining frosting. Smooth the surface with a spatula and sprinkle additional coconut flakes on top for a snowy, rustic finish.

Notes

  • Use room temperature ingredients to help the batter mix smoothly and prevent curdling.
  • Don’t overmix the batter; fold ingredients gently to keep the cake tender.
  • Maintain a gentle simmer for the double boiler when making frosting to avoid cooking egg whites too fast.
  • Add butter gradually to the frosting to keep it silky and prevent breaking or separation.
  • Store the frosted cake refrigerated and let it come to room temperature before serving for the best flavor and texture.
