- 1 ¾ cups all-purpose flour
- 1 ½ teaspoons baking powder

How To Make Key Lime Cake Recipe From Scratch

Creating this Key Lime Cake from scratch is a fun and rewarding experience. Follow these simple steps to bake your cake:
Step 1: Preheat the Oven
Begin by preheating your oven to 350°F (175°C). This will ensure that your cake bakes evenly and rises beautifully.
Step 2: Prepare the Cake Pans
Grease and flour two 9-inch round cake pans. This will help the cakes come out easily once they are baked.
Step 3: Mix Dry Ingredients
In a medium-sized bowl, whisk together the all-purpose flour, baking powder, baking soda, and salt. Set this mixture aside as you prepare the wet ingredients.
Step 4: Cream the Butter and Sugar
In a large mixing bowl, beat the softened unsalted butter and granulated sugar together on medium speed until the mixture is light and fluffy. This should take about 3-4 minutes.
Step 5: Add Eggs and Lime
Add the eggs, one at a time, mixing well after each addition. Then, incorporate the fresh lime juice and lime zest into the batter, blending until everything is well combined.
Step 6: Combine Wet and Dry Ingredients
Gradually add the dry ingredient mixture to the wet ingredients, alternating with the buttermilk. Start and end with the flour mixture, mixing just until combined. Be careful not to overmix; a few lumps are perfectly fine.
Step 7: Pour and Bake
Divide the batter evenly between the prepared cake pans. Bake in the preheated oven for 25-30 minutes or until a toothpick inserted in the center comes out clean.
Step 8: Cool the Cakes
Once baked, remove the cakes from the oven and let them cool in the pans for about 10 minutes. Then, carefully run a knife around the edges and turn them out onto wire racks to cool completely.
Step 9: Frosting (Optional)
While the cakes are cooling, consider making a lime-flavored cream cheese frosting or a simple whipped cream. This will complement the tangy cake beautifully.
Expert Tips
To ensure your Key Lime Cake turns out perfectly, keep these expert tips in mind:
- Use fresh lime juice and zest for the best flavor.
- Make sure your butter is at room temperature for easier creaming.
- Do not overmix the batter; this can lead to a tough cake.
- Check the cakes a few minutes before the recommended baking time, as ovens can vary.

Alternatively, you can refrigerate the cake for up to a week. For longer storage, consider freezing the cake. Wrap it tightly in plastic wrap and then in aluminum foil. It can be frozen for up to 3 months. Simply thaw in the refrigerator before serving.
