Ingredients You’ll Need
The magic of this Coconut Lime Layer Cake lies in its thoughtful combination of simple ingredients that each contribute to its delightful taste and texture. From the tender coconut milk enriching the sponge to the fresh lime juice adding zing to the frosting, every element plays a key role.
- Flour: The foundational ingredient that provides structure and the perfect crumb to the cake layers.
- Sugar: Adds sweetness and helps with browning for that beautiful golden crust.
- Eggs: Essential for binding ingredients together and giving the cake its light, airy consistency.
- Coconut milk: Infuses the cake with rich coconut flavor and moistness.
- Lime juice: Brings a fresh, tangy brightness that cuts through the sweetness.
- Lime zest: Intensifies the citrus aroma and adds a little textured burst of flavor.
- Whipped cream frosting: Light and fluffy, it complements the cake layers without overpowering.
How to Make Coconut Lime Layer Cake
Step 1: Prepare the Coconut Sponge
Begin by preheating your oven to 180°C. In a mixing bowl, combine the flour, sugar, and eggs, then slowly mix in the coconut milk until the batter is smooth and well combined. Pour the mixture into a greased cake pan and bake for 30 minutes, or until a toothpick inserted in the center comes out clean. This coconut sponge forms the moist and tender base that carries the bright lime flavors beautifully.
Step 2: Make the Lime Frosting
While the cake cools, prepare the frosting by gently folding the lime juice and lime zest into the whipped cream. This step infuses the frosting with refreshing citrus notes that make every bite lively yet creamy. Be careful not to overmix to maintain the airy texture of the whipped cream.
Step 3: Assemble the Layers
Once the sponge has cooled completely, carefully slice it into layers. Spread a generous amount of lime-infused whipped cream frosting between each layer to ensure every slice is bursting with flavor. This layering process also adds beautiful dimension to your cake, making it look as good as it tastes.
Step 4: Frost and Finish
Cover the entire cake evenly with the remaining whipped cream frosting. To give it an irresistible finishing touch, sprinkle toasted coconut flakes on top. The flakes add a pleasant crunch and extra coconut aroma that perfectly complement the softness of the cake and the zing of the lime.
How to Serve Coconut Lime Layer Cake

Garnishes
To elevate your Coconut Lime Layer Cake even further, consider garnishing with extra lime zest curls or thin slices of fresh lime. A sprinkling of toasted coconut flakes not only adds texture but also visually ties the tropical theme together beautifully.
Side Dishes
This cake pairs wonderfully with a light, fruity accompaniment like fresh berries or a citrus salad. For a cozy touch, serve alongside a cup of fragrant jasmine tea or a creamy coconut latte to enhance its rich and refreshing flavors.
Creative Ways to Present
For a fun twist, serve individual slices topped with a dollop of whipped cream and a drizzle of lime syrup for extra zing. You can even turn leftovers into mini parfaits layered with crushed cake, whipped cream, and fresh fruit—perfect for impressing guests or enjoying a fancy treat at home.
Make Ahead and Storage
Storing Leftovers
Your Coconut Lime Layer Cake keeps beautifully when stored in an airtight container in the refrigerator for up to three days. Covering it properly ensures the whipped cream frosting stays fresh without drying out the cake layers.
Freezing
For longer storage, you can freeze the cake before frosting by wrapping individual layers tightly in plastic wrap and aluminum foil. When you’re ready to indulge again, thaw the layers in the fridge overnight and assemble with freshly whipped lime frosting for a just-baked taste.
Reheating
This cake is best enjoyed chilled or at room temperature because warming can cause the frosting to melt. If desired, let refrigerated slices sit out for 20 minutes to soften slightly before serving, allowing the flavors to bloom perfectly.
FAQs
Can I use canned coconut milk for this cake?
Absolutely! Full-fat canned coconut milk is preferred for its rich flavor and creamy texture, which keeps the cake moist and delectably coconutty.
Is the lime zest necessary?
Yes, lime zest adds a bright, aromatic citrus punch that juice alone can’t provide. It enhances the overall lime flavor and adds visual appeal in the frosting.
Can I substitute the whipped cream frosting?
If you prefer, cream cheese frosting or a simple lime glaze can be used as alternatives, but whipped cream frosting offers a lightness that complements the coconut sponge perfectly.
How many layers should the cake have?
The recipe works wonderfully with two to three layers. Thinner layers make the cake easier to slice and provide more surface area for frosting.
Can I make this cake vegan?
With some adjustments—like using flax eggs, vegan whipped cream, and plant-based milk—you can create a vegan version that still captures the Coconut Lime Layer Cake’s charm.
