Essential Ingredients
Here’s what you’ll need to make this delicious dish:
- Cake Flour: Use cake flour for a lighter texture; it helps create that fluffy consistency we all crave. Gooey Butter Cake for a rich texture.
- Granulated Sugar: Sweetness is key here; adjust based on your preference for tartness versus sweetness.
- Baking Powder: Ensures the cake rises perfectly; check expiration dates for best results.
- Salt: Just a pinch balances the sweetness beautifully; don’t skip this crucial ingredient.
- Eggs: Use large eggs for better moisture and richness in the batter; room temperature works best.
- Key Lime Juice: Freshly squeezed juice packs more flavor than bottled; seek out those cute little key limes!
- Zest of Key Limes: Adds depth to the flavor profile; zest away before juicing!
- Sour Cream: This adds moisture and tanginess that takes the cake over the top.
- Unsalted Butter: Make sure it’s softened for easy mixing; it enriches the batter significantly.
- Cream Cheese: Essential for that rich frosting; ensure it’s at room temperature for easy blending.
- Powdered Sugar: For sweetness in the frosting, it dissolves easily and creates that smooth texture we want.
- Vanilla Extract: A splash rounds out the flavors beautifully; always opt for pure vanilla extract if possible.
- Milk or Heavy Cream: Adjust thickness in your frosting based on preference; cream gives a luxurious touch.

Let’s Make it Together!
Prepare Your Oven and Pans: Preheat your oven to 350°F (175°C). Grease and flour two 9-inch round cake pans to prevent sticking. You want those cakes to slide right out!
Create Your Dry Mix: In a medium bowl, whisk together cake flour, baking powder, and salt until well combined. This helps ensure even rising—trust me, lumps are not our friends.
Mingle Wet Ingredients: In another bowl, beat softened butter and sugar together until light and fluffy. Add eggs one at a time, mixing well after each addition. Then stir in key lime juice and zest—it should smell like paradise!
Combine Mixtures: Gradually add dry ingredients to wet ingredients while alternating with sour cream. Mix until just combined—overmixing can lead to dense cakes!
Bake Those Layers: Divide batter evenly between prepared pans and smooth tops using a spatula. Bake for about 25-30 minutes or until golden brown and a toothpick comes out clean.
Create Your Frosting: While cakes cool, beat cream cheese until creamy. Gradually add powdered sugar while mixing until smooth. Stir in milk or cream until desired consistency is achieved.
Frost Away: Once cooled completely, remove cakes from pans. Place one layer on a serving plate and spread frosting generously over top. Add the other layer and frost the top and sides as desired—don’t be shy!
This Key Lime Cake with Cream Cheese Frosting will surely be a hit! Now grab yourself a slice (or two) and enjoy every tangy bite!
