Ingredients for Key Lime Cake

Here’s what you’ll need to make this delicious dish:

  • All-Purpose Flour: Essential for that perfect cake structure; sift it for an extra light texture.

  • Granulated Sugar: This sweetener balances the tartness of the key limes and adds moisture.

  • Baking Powder: Ensures your cake rises beautifully; check expiration date for best results.

  • Salt: Just a pinch enhances all flavors; don’t skip this step!

  • Unsalted Butter: Softened to room temperature, this adds richness and moisture to your cake.

  • Eggs: Use large eggs for binding and adding moisture; they’re like glue but tastier.

  • Fresh Key Lime Juice: The star of the show! Freshly squeezed juice gives the best flavor; bottled just doesn’t cut it.

  • Zest of Key Limes: Adds a burst of citrus aroma and flavor; zest carefully to avoid bitter pith.

For the Frosting:

  • Powdered Sugar: Provides sweetness and smoothness; sift before using to avoid lumps.

  • Cream Cheese: Choose full-fat cream cheese for optimal creaminess in your frosting.

  • Unsalted Butter: Also used in frosting; make sure it’s soft so it blends easily with cream cheese.

The full ingredients list, including measurements, is provided in the recipe card directly below.

Recipe preparation

How to Make Key Lime Cake

Follow these simple steps to prepare this delicious dish:

Step 1: Preheat Your Oven

Preheat your oven to 350°F (175°C). Grease and flour two round cake pans. You want them ready because nobody likes a sticking situation!

Step 2: Mix Dry Ingredients

In a large bowl, whisk together all-purpose flour, granulated sugar, baking powder, and salt. Mixing these dry ingredients ensures even distribution of flavors.

Step 3: Cream Butter and Sugar

In another bowl, cream together softened unsalted butter and remaining sugar until fluffy—about two minutes should do it. Add eggs one at a time while mixing well after each addition.

Step 4: Combine Wet Ingredients

Pour in fresh key lime juice along with its zest into the butter mixture. Mix until everything is well combined—this is where things start getting exciting!

Step 5: Combine Mixtures

Slowly add dry ingredients into wet ingredients until just combined. Do not over-mix unless you want a dense cake instead of that light-and-fluffy dream we’re after!

Step 6: Bake It Up

Divide batter evenly between prepared pans and bake for about 25-30 minutes or until a toothpick inserted in the center comes out clean. Let them cool completely before frosting.

Now you can frost your cooled cakes! For frosting perfection, beat together softened cream cheese and unsalted butter until creamy. Gradually mix in powdered sugar until smooth.

Transfer layers onto a serving platter and spread that luscious frosting generously on top and around the sides. A slice of this heavenly Key Lime Cake will have everyone asking for seconds (and maybe thirds!). Enjoy every zesty bite!
