- 3 eggs: Acts as a binding agent and helps create a fluffy cake texture.
- 1 cup coconut milk: Infuses rich, creamy coconut flavor and moisture throughout the sponge.
- 2 tablespoons lime juice: Delivers a fresh and tangy kick to brighten the frosting.

How to Make Coconut Lime Layer Cake
Step 1: Prepare the Coconut Sponge
Start by preheating your oven to 180°C. In a mixing bowl, combine the flour, sugar, eggs, and coconut milk until you get a smooth batter. This mixture results in a soft, moist sponge with a subtle coconut richness. Pour the batter into a greased cake pan and bake for about 30 minutes, or until a toothpick inserted in the center comes out clean. The oven’s warmth transforms the batter into fluffy layers that are the foundation of this dreamy cake.
Step 2: Make the Lime Frosting
While the sponge is baking, whisk together the whipped cream frosting with the lime juice and lime zest. This step infuses the frosting with fresh, citrusy flavors that perfectly complement the coconut sponge. The combination of creamy sweetness and tangy zest creates an irresistible balance that will dance on your palate.
Step 3: Layer and Frost the Cake
Once the cake layers have cooled completely, slice them horizontally if you baked a single thick layer, or prepare your individual layers. Spread a generous amount of the lime-infused whipped cream frosting evenly between each layer and around the sides of the cake. This layering not only adds beautiful texture but also ensures every bite is bursting with flavor.
Step 4: Garnish and Chill
Finish by sprinkling coconut flakes lightly on top for a lovely crunch and enhanced tropical visual appeal. Pop the cake into the refrigerator to allow the frosting to set and the flavors to meld for at least an hour before serving. This chilling step makes your Coconut Lime Layer Cake even more luscious and refreshing.
How to Serve Coconut Lime Layer Cake

Garnishes
Adding fresh garnishes can elevate your Coconut Lime Layer Cake from delightful to spectacular. Try fresh lime slices or zest curls for extra zing, toasted coconut flakes for crunch and nuttiness, or even edible flowers for a playful, elegant touch. These little details make your cake feel thoughtfully crafted and ready to impress.
Side Dishes
This cake pairs beautifully with light, tropical-inspired accompaniments. A simple fruit salad featuring mango, pineapple, and kiwi or a scoop of coconut sorbet can complement the main dessert without overpowering it. Even a crisp mint tea or a refreshing limeade can be wonderful beverage partners for this bright and creamy cake.
Creative Ways to Present
Think beyond the traditional cake stand! Serve your Coconut Lime Layer Cake on a rustic wooden board for a casual vibe or on a bright ceramic platter to echo its tropical roots. For a fun twist, slice into small square portions and serve as individual mini cakes or layer the ingredients in clear glass trifle dishes for beautiful, layered visual appeal.
Make Ahead and Storage
Storing Leftovers
Keep any leftover Coconut Lime Layer Cake tightly covered in the refrigerator to maintain the fresh taste and texture. Wrapped well or stored in an airtight container, the cake stays moist and flavorful for up to 3 days, giving you plenty of chances to enjoy a slice (or two) later on.
Freezing
If you want to save the Coconut Lime Layer Cake for a longer time, freezing is a great option. Wrap individual slices or the whole cake securely in plastic wrap followed by aluminum foil to protect against freezer burn. Frozen correctly, the cake keeps well for up to 2 months. Thaw it overnight in the fridge to enjoy the same fresh-tasting layers.
Reheating
This cake is best enjoyed chilled, so reheating isn’t necessary. If you prefer room temperature cake, simply leave slices out for 15–20 minutes to lose any chill before serving. This way, the frosting remains creamy and the sponge perfectly tender.
FAQs
Can I use regular milk instead of coconut milk?
While you can substitute regular milk, you’ll lose the distinct coconut flavor that gives this cake its tropical character. For the best Coconut Lime Layer Cake experience, coconut milk is highly recommended.
Is this cake suitable for a dairy-free diet?
You can easily adapt the recipe by using dairy-free whipped cream frosting and ensuring the coconut milk is canned or from a quality source. This makes the Coconut Lime Layer Cake a wonderful option for those avoiding dairy.
How do I get the lime zest without the bitter white pith?
Use a microplane or fine grater to zest just the green part of the lime peel. Avoid the white pith beneath, which is bitter and can affect the cake’s flavor.
Can I make this cake ahead of time for a party?
Absolutely! You can bake the sponge and prepare the frosting a day in advance. Assemble and frost the cake a few hours before serving, then refrigerate. The flavors will deepen and the texture will be stellar.
What can I substitute for whipped cream frosting?
If you prefer, cream cheese frosting with added lime zest and juice can be a delicious alternative. It adds a tangy creaminess that complements the coconut layers beautifully.
