Moist & Tangy Key Lime Pound Cake Ingredients
For the Batter
- All-Purpose Flour – Provides structure for the cake; ensure it’s sifted for a lighter texture.

- Unsalted Butter – Brings richness and a tender crumb; can be substituted with margarine for a dairy-free option.
- Large Eggs – Provides binding and moisture; substitute with applesauce (1/4 cup per egg) for a vegan option.
- Fresh Key Lime Juice – Central flavor component giving tanginess; use regular lime juice if key limes are unavailable.
- Key Lime Zest – Enhances flavors and adds aromatic oils.
For the Glaze
- Powdered Sugar – Used for the glaze, adding sweetness and a smooth texture; no substitutions recommended for glaze texture.
- Fresh Lime Juice – Provides the tangy twist to the glaze; it beautifully complements the sweetness of the powdered sugar.
Step‑by‑Step Instructions for Moist & Tangy Key Lime Pound Cake
Step 1: Prepare the Batter
Preheat your oven to 350°F (175°C) and grab a mixing bowl. Begin by creaming together 1 cup of softened unsalted butter and 2 cups of granulated sugar until the mixture is light and fluffy, which should take about 3-4 minutes. Next, add 4 large eggs one at a time, ensuring each is fully incorporated before adding the freshly squeezed key lime juice and zest.
Step 2: Combine Dry Ingredients
In a separate bowl, sift together 2 ½ cups of all-purpose flour and a pinch of salt. Gradually add the flour mixture to your butter and egg mixture while gently stirring until just combined. Be careful not to overmix; you want your batter to be smooth yet slightly lumpy to achieve the perfect texture in your Moist & Tangy Key Lime Pound Cake.
Step 3: Bake the Cake
Grease and flour a 9×5-inch loaf pan, then pour the cake batter into the pan. Use a spatula to spread it evenly. Place the pan in your preheated oven and bake for 50-60 minutes, or until a toothpick inserted in the center comes out clean. Keep an eye on the cake during the last few minutes to avoid over-browning.
Step 4: Cool and Glaze
Once baked, remove your pound cake from the oven and let it cool in the pan for about 10 minutes. After that, gently invert the cake onto a wire rack to cool completely. For the finishing touch, combine powdered sugar with a bit of fresh key lime juice to make a glaze, then drizzle it over the cooled cake for a shiny, delectable finish.

Expert Tips for Moist & Tangy Key Lime Pound Cake
-
Room Temperature Ingredients: Using room temperature butter, eggs, and lime juice ensures better mixing, contributing to a tender cake.
-
Sifting Flour: Don’t skip sifting the flour! This helps aerate it, resulting in a lighter, fluffier Moist & Tangy Key Lime Pound Cake.
-
Mixing Method: Mix the batter just until combined. Overmixing can lead to a dense texture, so stop as soon as you no longer see dry flour.

Baking Time: Keep an eye on your cake towards the end of the baking time; if it browns too quickly, lightly tent it with aluminum foil to protect it.

Moist & Tangy Key Lime Pound Cake Recipe FAQs
How do I select ripe key limes?
Absolutely! When choosing key limes, look for ones that are firm and slightly heavy for their size. Their skin should be smooth and glossy, with a vibrant green color. Avoid any limes with dark spots or blemishes, as these can indicate overripeness.
What is the best way to store leftover pound cake?
Very! Once the cake has cooled completely, you can keep the Moist & Tangy Key Lime Pound Cake at room temperature in an airtight container or covered with plastic wrap for up to 3 days. If you want to extend freshness, refrigerate it, tightly wrapped, for up to 1 week.
Can I freeze this cake? If so, how?

Why did my pound cake turn out dense?
Very often, a dense cake can result from overmixing the batter. Ensure you mix the dry ingredients into the wet until just combined. Also, remember to use room temperature ingredients—this aids in the mixing process. If your baking powder isn’t fresh, it can also lead to density issues; double-check your leavening agent’s expiration date.
Is this cake safe for pets or those with allergies?
Good question! This Moist & Tangy Key Lime Pound Cake contains ingredients that aren’t suitable for pets, especially sugar and butter. If preparing for someone with allergies, check the ingredient list closely, as it contains eggs and gluten from the flour.
