In this post, we’ll dive deep into the world of Key Lime Cake, sharing not only how to make it but also how to elevate your baking game.

Ingredients Needed

Here’s what you’ll need to craft a perfect Key Lime Cake, along with some sensory descriptions to spark your culinary imagination:

• 2 ⅔ cups all-purpose flour (333 g): The foundation of your cake, giving it structure and a light crumb.
• 2 cups granulated sugar (400 g): Adds sweetness that balances the tartness of the limes, making every bite deliciously festive.
• 1 teaspoon baking powder: Helps the cake rise, creating that fluffy texture we all crave.
• ½ teaspoon baking soda: Enhances the leavening and contributes to a lighter cake.
• 1 teaspoon table salt: Enhances flavors; a little salt goes a long way in baking.
• ½ cup unsalted butter (113 g), cut into 8 pieces: Richness and moisture come from butter, enriching the cake with a buttery flavor.
• ¼ cup avocado, vegetable, or canola oil (60 ml): Adds moisture and a subtle richness that complements the butter.
• 1 Tablespoon lime or key lime zest: A concentrated burst of lime flavor that awakens the palate.
• 1 ½ Tablespoons key lime juice: The magic ingredient that imparts that unique tart flavor distinguishing Key Lime Cake.
• 1 ½ scant cups whole milk (333 ml): Keeps the batter moist and helps create a tender crumb.
• 1 teaspoon vanilla extract: A classic flavor enhancer that adds depth to your cake.
• ⅓ cup key lime juice (80 ml): Very much essential for the frosting, giving it a wonderfully tart profile.
• 2 Tablespoons granulated sugar: Sweetness for the frosting to balance the acidity of the lime.
• ¼ teaspoon table salt: Similar to before, it enhances the frosting’s flavor.
• 2 Tablespoons unsalted butter (28 g), cut into pieces: Adds thickness and richness to the curd.
• ¾ cup unsalted butter (170 g), softened: For that creamy, dreamy frosting.
• 6 oz cream cheese (170 g), softened: Contributes to a rich, velvety texture.
• 4-5 cups powdered sugar (500-625 g): Sweetness and a fluffy texture for your frosting.
• ¼ cup graham cracker crumbs (28 g) for decorating: A nod to classic Key Lime Pie that introduces a crunchy element.

How to Make Key Lime Cake

Step 1: Pre-heat the Oven

Preheat your oven to 350°F (175°C). While the oven warms up, it’s time to prep your pans!

Step 2: Prepare the Cake Pans

Thoroughly grease and flour the sides of three 8-inch cake pans, tapping out any excess flour. Line the bottoms with parchment paper for easy release.

Step 3: Mix Dry Ingredients

In a large bowl (or using a stand mixer), combine flour, sugar, baking powder, baking soda, and salt. Ensure it’s well mixed.

Step 4: Incorporate Butter

With the mixer on low speed, add softened butter one tablespoon at a time. Allow each piece to be fully incorporated until you achieve a sandy texture.

Step 5: Add Oil and Zest

Mix in the oil and lime zest until well combined, then set the mixture aside.

Step 6: Prepare the Wet Ingredients

In a large measuring cup, add key lime juice, followed by enough milk to reach the 1 ½ cup line. Whisk in the eggs and vanilla.

Step 7: Combine Wet and Dry Ingredients

Slowly add the wet mixture into the batter on low speed. Scrape down the sides to ensure everything is evenly mixed. The batter should be smooth and uniform.

Step 8: Bake the Cakes

Evenly divide the batter into the prepared pans, which should weigh about 460 grams each. Bake for 26-28 minutes, or until a toothpick comes out clean. Let the cakes cool in the pans for 10-15 minutes before inverting them onto a cooling rack.

Step 9: Make the Frosting

While the cakes cool, in a small saucepan, whisk egg yolks, key lime juice, sugar, and salt. Add butter and cook over medium/low heat until thickened. Strain into a bowl and cool completely.

Step 10: Prepare the Frosting

Beat softened butter and cream cheese until creamy. Gradually add powdered sugar. Then incorporate the cooled lime curd until you reach your desired sweetness.

Step 11: Frost the Cake

Level the cooled cakes if necessary. Frost each layer evenly and coat the outside. Optionally, press graham cracker crumbs around the base and top it off with whipped cream, lime zest, or crumbs.

Step 12: Chill and Serve

Let the cake chill in the fridge for at least 30 minutes before slicing. Enjoy!

Healthier Alternatives for Key Lime Cake

Want to make your cake more health-conscious? Consider these alternatives:

• Substitute half of the all-purpose flour with almond or coconut flour for added fiber.
• Use stevia or monk fruit sweetener instead of granulated sugar.
• Replace butter with unsweetened applesauce for moisture without the added fat.
• Incorporate Greek yogurt instead of cream cheese for a lighter frosting.

Serving Suggestions

Pair your Key Lime Cake with fresh berries or drizzle with a simple berry sauce for a refreshing contrast. Serve with a scoop of vanilla ice cream for a delightful dessert experience.

Common Mistakes to Avoid

1. Overmixing the Batter: This can lead to dense cakes. Mix just until combined.
2. Not Measuring Accurately: Use a kitchen scale or proper measuring cups for consistent results.
3. Skipping the Cooling Stage: Frosting a warm cake can lead to melting frosting and a mess!

Storing Tips for Key Lime Cake

Store leftovers in an airtight container at room temperature for up to three days, or in the fridge for a week. For longer storage, freeze the cake layers for up to three months and frost upon thawing for maximum freshness.
