1 teaspoon vanilla extract
-
Optional: extra lime zest for garnish
Make sure to use fresh key limes for the best flavor. The zest and juice create a bright, tangy profile that truly makes this cake shine!
Prepare the cake batter
Now, let’s bring these ingredients together.
- Preheat your oven to 350°F (175°C) and grease and flour two 9-inch round cake pans.
- In a large mixing bowl, cream the softened butter and granulated sugar together until light and fluffy. This process usually takes about 3 to 5 minutes.
- Beat in the eggs one at a time, ensuring each is fully incorporated before adding the next.
- Mix in the lime zest and freshly squeezed key lime juice.
- In a separate bowl, whisk together the flour, baking powder, baking soda, and salt.
- Gradually add the dry mix to the wet ingredients, alternating with the buttermilk. Start and end with the flour mixture, mixing until just combined.
Bake the Key Lime Cake layers
Your batter is ready! Now it’s time to bake:
- Divide the batter evenly between the prepared cake pans.
- Bake in the preheated oven for 25 to 30 minutes or until a toothpick inserted into the center comes out clean.
- Allow the cakes to cool in the pans for 10 minutes, then remove them from the pans and let them cool completely on a wire rack.
Make the key lime curd
Next up is the tangy key lime curd that will fill your delightful cake layers:
- In a medium saucepan, whisk together the egg yolks, sugar, lime juice, and lime zest over medium heat.
- Cook the mixture, constantly stirring, until it thickens (about 10 minutes). A great tip from chefs over at Serious Eats is that you should avoid letting it boil to prevent curdling.
- Remove from heat and whisk in the butter until smooth. Let the curd cool before spreading it onto your cake.
Prepare the frosting
A rich frosting will complement your cake perfectly:
- In a large mixing bowl, beat the heavy whipping cream, powdered sugar, and vanilla extract until soft peaks form.
- This frosting will need to be quick, so ensure your cream is cold for the best results.
Assemble and frost the cake
Finally, let’s put it all together!
- Place one layer of the cooled cake on a serving plate and spread a generous layer of the key lime curd on top.
- Place the second layer on top and frost the entire cake with the whipped cream frosting.
- Don’t forget to garnish with extra lime zest for that beautiful finish!

Baking notes for Key Lime Cake
When whipping up your delightful key lime cake, there are a few key tips to keep in mind to ensure it turns out perfectly every time!
Ingredients Matter
Using fresh key limes instead of bottled juice will elevate the flavor. If you can’t find them, regular limes will work, but the taste will be slightly different. For that extra zing, zest the limes before juicing to capture all the vibrant flavors.
Baking Tips

- Check Your Oven: Ovens can be unpredictable. Keep an oven thermometer handy to ensure accuracy. A disparity of even 10°F can affect baking time and texture.
Cooling Time
After baking, let the cake sit in the pan for about 10 minutes before transferring it to a rack. This step helps prevent it from breaking apart. Cooling completely will also help set the flavors, giving you that delicious key lime tang in every bite!

Tips for Making the Perfect Key Lime Cake
Creating a Key Lime Cake that wows everyone at your gathering is simpler than you may think! Here are some tips to help you achieve that perfect balance of tart and sweet.
Use Fresh Ingredients
For that genuine key lime flavor, always use fresh key limes instead of bottled juice. The zest adds a zesty twist that bottled varieties just can’t match. If you can’t find key limes, regular limes can work in a pinch.
Mind the Temperature
Make sure your eggs and butter are at room temperature before mixing. This small step is crucial for achieving that dreamy texture. Room temperature ingredients blend better, resulting in a more consistent batter.
Measure Accurately
Baking is a science, so use a kitchen scale or proper measuring cups to ensure your flour, sugar, and other ingredients are spot on. Too much flour can lead to a dense cake!
Don’t Rush the Cooling Process
Once your key lime cake is out of the oven, give it time to cool completely before frosting it. This helps the flavors meld, making every bite taste even better. Also, chilling the cake before serving enhances the refreshing flavors.
Experiment with Frosting
Consider pairing your cake with a tangy cream cheese frosting or a whipped topping with a hint of lime for that extra zing. It can elevate the flavors and give your dessert a delightful finish.
With these tips in mind, you’re ready to bake your own key lime cake masterpiece! Happy baking!

How can I make my Key Lime Cake more tart?
If you prefer your key lime cake with a bit more zing, here are a few tips:
-
Increase the juice: Add an extra tablespoon (or two) of key lime juice to your batter. Taste as you go!
