What Are Coconut Cake with Sour Cream Frosting?
Coconut cake has deep roots in Southern cuisine, often associated with celebration and indulgence. Traditionally, coconut cakes are crafted with layers of moist sponge cake infused with coconut flavor and topped with rich frosting. The unique aspect of this version comes from the addition of sour cream, which not only enhances moisture but also adds a delightful tang that perfectly complements the sweetness of the coconut.
The flavors meld beautifully, resulting in a cake that’s wonderfully soft and rich yet not overly sweet—a rare find in many desserts. The addition of shredded coconut gives it a chewy texture that enhances the overall mouthfeel. This cake is perfect for everything from birthday parties to holiday gatherings, or even just a cozy afternoon treat at home!

Ingredients
Here’s what you’ll need to make this delightful Coconut Cake with Sour Cream Frosting:
For the Cake:
- 2 cups all-purpose flour (I prefer King Arthur’s for its quality)
- 1 ½ cups granulated sugar (substitute with coconut sugar for a deeper flavor)
- ½ cup unsalted butter, softened (always use room temperature for easy creaming)
- 1 cup sour cream (I love using full-fat for the creamiest texture)
- ½ cup coconut milk (look for the canned type for richer flavor)
- 3 large eggs, room temperature (helps with even mixing)
- 1 teaspoon baking powder (check expiration for best results)
- ½ teaspoon baking soda
- 1 teaspoon vanilla extract (use pure vanilla for optimal taste)
- 1 cup shredded coconut (unsweetened is my go-to for flavor balance)
For the Frosting:
- 1 cup unsalted butter, softened (same room temperature note applies)
- 4 cups powdered sugar (sifted for smooth frosting)
- ¼ cup sour cream
- 1 teaspoon vanilla extract
- 1 cup shredded coconut (for topping and extra decoration)
Prep Notes: Make sure to soften your butter and eggs before use to ensure a smooth batter. Also, I highly recommend measuring your dry ingredients correctly; using the spoon-and-level method can help you avoid dense cakes.

Step-by-Step Instructions
Let’s break this down into easy, actionable steps to ensure success:
Preheat the oven to 350°F (175°C). Prepare two 9-inch round cake pans by greasing with butter and dusting lightly with flour.
Cream the butter and sugar: In a large mixing bowl, use an electric mixer on medium speed to beat the softened butter and granulated sugar until light and fluffy (about 3-5 minutes). This step is crucial as it incorporates air for a lighter cake.
Add the eggs: Add the eggs one at a time, mixing well after each addition. You’ll want a smooth batter here!
Stir in wet ingredients: Next, introduce the sour cream, coconut milk, and vanilla extract. Mix thoroughly until everything is well combined.
Mix dry ingredients: In another bowl, whisk together the flour, baking powder, and baking soda.
Combine wet and dry: Gradually add this dry mixture to your wet ingredients, mixing just until combined—don’t overmix. It’s okay if a few lumps remain!
Fold in the coconut: Carefully fold in the shredded coconut until evenly distributed.
Divide the batter: Pour the batter evenly into the prepared pans, smoothing the tops with a spatula for an even bake.
Bake: Place the pans in the preheated oven and bake for 25-30 minutes, or until a toothpick inserted in the center comes out clean. Keep an eye on them after the 25-minute mark!
Cool: Once baked, allow the cakes to cool in the pans for about 10 minutes before transferring them to wire racks to cool completely.
Make the frosting: For the frosting, beat the softened butter in a mixing bowl until creamy. Gradually add the powdered sugar, sour cream, and vanilla extract, beating until light and fluffy.
Assemble the cake: Once the cakes are completely cooled, frost the top of one layer, place the second layer on top, and then frost the top and sides of the cake.
Garnish: Finish off by sprinkling additional shredded coconut on top for a beautiful presentation.
Slice and serve: Enjoy this delightful cake at gatherings or as a sweet treat for yourself!

Expert Tips & Tricks
Avoid Dry Cake: Make sure not to overbake. Start checking for doneness at 25 minutes to ensure a moist cake.
Room Temperature Ingredients: This is vital for the ingredients to incorporate smoothly, giving you a fluffier crumb.
Storing Leftovers: If you have leftover cake, keep it in an airtight container at room temperature for up to 3 days or in the fridge for about a week.
Make-Ahead: You can bake the layers a day in advance. Just wrap them tightly in plastic wrap and refrigerate until you’re ready to frost.
Common Mistakes: One common pitfall is over-mixing the batter. This can give a dense cake. Mix until just combined and resist the urge to keep beating!
Serving Suggestions
Pair this Coconut Cake with a dollop of whipped cream for extra indulgence or serve it alongside a refreshing fruit salad to balance the sweetness. For a special touch, consider a splash of tropical cocktails for summer barbecues, or a cozy cup of coffee for intimate gatherings.
To make it extra festive, consider adding edible flowers for presentation—simple yet stunning!
Variations & Substitutions
Flavor Combinations: Try adding lemon or lime zest for a refreshing zing or incorporating nuts for added crunch.
Dietary Restrictions: For a gluten-free version, substitute cake flour with a gluten-free blend. Vegans can use flax eggs and plant-based butter instead of regular butter.
Seasonal Adaptations: In the fall, a hint of pumpkin spice can give this cake a delightful twist. In spring, try adding fresh berries to the frosting for a burst of color!
