Ingredients

For the Cake:

  • All-purpose flour: 3 cups (sifted)
  • Baking powder: 1 tbsp
  • Salt: ½ tsp
  • Unsalted butter: 1 cup (2 sticks), softened to room temperature
  • Granulated sugar: 2 cups
  • Large eggs: 4 (room temperature)
  • Vanilla extract: 1 tsp
  • Coconut extract: 1 tsp
  • Full-fat coconut milk: 1 cup (canned is best for richness)

For the Seven-Minute Frosting:

  • Egg whites: 2 large
  • Granulated sugar: 1 ½ cups
  • Cold water: 5 tbsp
  • Cream of tartar: ¼ tsp (or 1 tsp light corn syrup)
  • Salt: A pinch
  • Vanilla extract: 1 tsp

The Finish:

  • Sweetened shredded coconut: 2 cups (for coating the outside)

Instructions

1. Prepare the Layers

  1. Preheat your oven to 175°C (350°F). Grease and flour two 9-inch round cake pans.
  2. Whisk Dry Ingredients: In a medium bowl, sift together the flour, baking powder, and salt.
  3. Cream Butter & Sugar: In a large bowl, beat the softened butter and sugar together until light and fluffy (about 3-4 minutes).
  4. Add Eggs: Add eggs one at a time, beating well after each addition. Mix in the vanilla and coconut extracts.
  5. Alternate Liquid/Dry: Gradually add the dry ingredients to the butter mixture, alternating with the coconut milk. Start and end with the flour. Do not overmix!
  6. Bake: Divide the batter evenly between the pans. Bake for 30–35 minutes or until a toothpick comes out clean.
  7. Cool: Let the cakes cool in the pans for 10 minutes, then turn them out onto a wire rack to cool completely before frosting.

2. Make the Seven-Minute Frosting

  1. Double Boiler Setup: Combine egg whites, sugar, water, and cream of tartar in the top of a double boiler (or a heat-proof glass bowl over a pot of simmering water). Ensure the water doesn’t touch the bottom of the bowl.
  2. Whisk Constantly: Using a handheld electric mixer, beat the mixture on low speed for 1 minute.
  3. Heat and Beat: Increase speed to high and beat over the simmering water for about 7 minutes (hence the name!) until the frosting forms stiff, glossy peaks.
  4. Finish: Remove from heat, add vanilla extract, and continue beating for another 2 minutes to cool it slightly and maintain its structure.

3. Assembly

  1. Place one cake layer on your serving plate. Spread a thick layer of frosting over the top.
  2. Place the second layer on top. Cover the top and sides of the entire cake with the remaining frosting.
  3. The Coconut Finish: Immediately press the shredded coconut into the sides and top of the cake while the frosting is still tacky.

Service Suggestions

  • Fruit Pairing: Serve with a side of fresh raspberries or mango slices to cut through the sweetness.
  • Toasted Version: If you prefer a nuttier flavor, toast half of the coconut in a pan for 3 minutes before applying it to the cake.
  • Beverage: Pairs beautifully with a light Earl Grey tea or a dessert sherry.

Storage Tips

  • Room Temperature: This cake is best eaten the day it’s made. However, because of the “boiled” nature of the frosting, it can sit at room temp for up to 24 hours.
  • Refrigeration: Store in an airtight container for up to 3 days. Note that the frosting may become slightly “marshmallowy” or chewy in the fridge.
  • Freezing: You can freeze the cake layers (wrapped tightly) for up to 3 months, but the Seven-Minute Frosting does not freeze well.

FAQs

Q: Why did my frosting turn out runny?
A: This usually happens if the egg whites weren’t beaten long enough over the heat or if the humidity is very high. Ensure your bowl is completely grease-free before starting.
Q: Can I use dessicated coconut instead of shredded?
A: Yes, but shredded (moist) coconut gives that iconic “shaggy” look seen in your photo and provides a better texture.
Q: Can I make this a 3-layer cake?
A: Absolutely. Just divide the batter into three pans and reduce the baking time to about 22–25 minutes.

Conclusion

This Coconut Cake is the definition of a “crowd-pleaser.” The Seven-Minute Frosting provides a light, airy sweetness that doesn’t feel as heavy as traditional buttercream, making it the perfect vehicle for all that delicious coconut. Happy baking!
