Classic Southern Coconut Layer Cake

There is something undeniably show-stopping about a traditional Southern Coconut Layer Cake. Featuring ultra-moist, tender yellow cake layers soaked with coconut goodness, a rich filling, and a blanket of fluffy white frosting coated in shredded coconut, it is the ultimate celebration dessert.

Why This Recipe Works

• The Coconut Milk Soak: Drizzling warm coconut milk or sweetened coconut cream over the warm cake layers ensures every bite stays moist and tender for days without getting soggy.
• Fluffy Cream Cheese Frosting: Standard buttercream can sometimes overpower a cake with pure sugar. A cream cheese frosting brings a subtle tang that balances the sweet, tropical notes of the coconut.
• Sweetened Shredded Coconut: Coating the outside in shredded coconut doesn’t just look stunning—it adds a delicate, chewy texture that contrasts beautifully with the soft crumb.

Ingredients

For the Moist Cake Layers:

• 2 ½ cups (300 g) cake flour (or all-purpose flour)
• 2 ½ teaspoons baking powder
• ½ teaspoon baking soda
• ½ teaspoon fine sea salt
• ¾ cup (1 ½ sticks / 170 g) unsalted butter, softened to room temperature
• 1 ½ cups (300 g) granulated white sugar
• 3 large eggs, room temperature
• 1 large egg yolk
• 1 teaspoon pure vanilla extract
• 1 teaspoon coconut extract
• 1 cup (240 ml) canned full-fat coconut milk (stirred well)

For the Cake Soak & Filling:

• ⅓ cup (80 ml) sweetened condensed milk or coconut cream
• ¼ cup (60 ml) warm coconut milk
• (Optional) ⅓ cup lemon curd or pineapple filling for a tropical twist between layers

For the Frosting & Finish:

• 8 oz (225 g) cream cheese, softened to room temperature
• ½ cup (1 stick / 115 g) unsalted butter, softened
• 3 ½ to 4 cups (420 g–480 g) powdered sugar, sifted
• 2 tablespoons heavy cream or coconut milk
• 1 teaspoon coconut extract (or vanilla extract)
• 2 to 2 ½ cups sweetened shredded coconut (for covering the cake)

Step-by-Step Instructions

1. Prep the Pans and Oven

Preheat your oven to 350°F (175°C). Grease two 9-inch round cake pans with butter, line the bottoms with parchment paper rounds, and dust the sides lightly with flour.

2. Mix the Cake Batter

1. In a medium bowl, whisk together the 2 ½ cups cake flour, 2 ½ tsp baking powder, ½ tsp baking soda, and ½ tsp salt.
2. In a large mixing bowl (or stand mixer fitted with the paddle attachment), beat the ¾ cup softened butterand 1 ½ cups granulated sugar on medium-high speed for 3 to 4 minutes until light, pale, and fluffy.
3. Add the 3 eggs and 1 egg yolk one at a time, mixing well after each addition. Stir in the 1 tsp vanilla extract and 1 tsp coconut extract.
4. With the mixer on low speed, alternate adding the dry flour mixture and the 1 cup coconut milk in three additions, beginning and ending with the flour. Mix just until the batter comes together smoothly—do not overmix!

3. Bake and Soak

1. Divide the batter evenly between your prepared pans and smooth the tops.
2. Bake at 350°F (175°C) for 25 to 30 minutes, or until a toothpick inserted into the center comes out clean.
3. While the cakes are warm, whisk together the ⅓ cup sweetened condensed milk and ¼ cup warm coconut milk.
4. Poke a few shallow holes across the top of the warm cake layers with a toothpick, then spoon the coconut soak evenly over both layers. Let the cakes cool in the pans for 20 minutes, then invert onto wire racks to cool completely.

4. Whip the Cream Cheese Frosting

In a large bowl, beat the 8 oz softened cream cheese and ½ cup softened butter for 2 minutes until smooth and lump-free. Gradually add the powdered sugar, 2 tbsp heavy cream, and 1 tsp coconut extract. Beat on medium-high speed for another 2 minutes until light and fluffy.

5. Assemble and Coat

1. Place the first cooled cake layer on a serving platter. Spread a thick layer of frosting over the top (if using lemon curd or fruit filling, spread a layer of that first, then top with a thin layer of frosting).
2. Place the second cake layer on top. Cover the top and sides of the entire cake with the remaining frosting in a smooth layer.
3. Gently press the sweetened shredded coconut into the frosting all over the top and sides of the cake until completely covered.

6. Chill and Serve

Refrigerate the cake for at least 2 hours before slicing. This gives the frosting time to set and allows the coconut flavor to infuse deeply into the cake layers.

Baker’s Tips

• Cake Flour vs. All-Purpose: Using cake flour yields an exceptionally soft, fine crumb that melts in your mouth. If you only have all-purpose flour, remove 2 tablespoons per cup and replace them with cornstarch, then sift twice!
• Toast the Coconut (Optional): If you like a deeper, nutty flavor, spread half of the shredded coconut onto a baking sheet and bake at 325°F (165°C) for 5 to 8 minutes until golden-brown before pressing it onto the outside.
