3.Instructions: How to Make Key Lime Cake
Step 1: Preheat the Oven
Preheat your oven to 350°F (175°C). Grease and flour two 8-inch round cake pans and set them aside.

Step 2: Prepare the Cake Batter
In a large bowl, combine the flour, sugar, baking powder, baking soda, and salt. In a separate bowl, beat together the butter, eggs, and buttermilk until smooth. Gradually add the dry ingredients to the wet mixture, blending well. Stir in the key lime juice, zest, and vanilla extract.

Step 3: Bake the Cake

Pour the batter evenly into the prepared pans and bake for 25-30 minutes or until a toothpick inserted in the center comes out clean. Let the cakes cool in the pans for 10 minutes before transferring them to a wire rack to cool completely.

Step 4: Make the Cream Cheese Frosting
While the cake is cooling, prepare the frosting. In a large bowl, beat the softened cream cheese and butter until smooth and creamy. Gradually add the powdered sugar, mixing well after each addition. Stir in the key lime juice and vanilla extract, and beat until light and fluffy.

Step 5: Assemble the Cake
Once the cakes are completely cool, spread a layer of frosting on the top of one cake. Place the second cake on top and frost the entire cake, including the sides. Garnish with key lime zest for a pop of color and extra lime flavor.

Step 6: Chill and Serve
Refrigerate the cake for at least 30 minutes before serving to let the flavors meld. Enjoy your tangy and refreshing key lime cake!

5.Frequently Asked Questions (FAQs)

Can I use regular limes instead of key limes?
Yes, if you can’t find key limes, you can use regular limes. However, key limes have a distinct, more intense flavor that gives the cake its signature tangy taste. The cake will still be delicious with regular limes, but the flavor will be slightly different.

How should I store key lime cake?
Store the key lime cake in an airtight container in the refrigerator for up to 3-4 days. You can also freeze the cake (without the frosting) for up to 2 months. Thaw it in the refrigerator overnight before frosting and serving.

Can I make the cake ahead of time?
Yes! You can bake the cake layers up to two days in advance. Keep them tightly wrapped and refrigerated. Make the frosting and assemble the cake on the day you plan to serve it for the freshest taste.

Is key lime cake too tart?
Not at all! The cake strikes the perfect balance between sweet and tangy. The key lime juice adds a refreshing flavor, but the sugar and cream cheese frosting help mellow out the tartness, making it a delightful dessert for any occasion.

Can I use bottled key lime juice?

Freshly squeezed key lime juice is always recommended for the best flavor. However, if fresh key limes are unavailable, you can use bottled key lime juice as a substitute. Just be sure to use a high-quality brand with no added preservatives.
