Cream the Butter and Shortening
Start by preheating your oven to 325°F (163°C). In a mixing bowl, beat together the soft butter and shortening at medium speed. This ensures that your fats are well combined and creates a lovely base for your Key Lime Pound Cake. Aim for a creamy texture that’s light and fluffy.
Mix in the Sugar and Eggs
Once your butter and shortening are creamed, gradually add in the sugar. Continue to beat at medium speed until the mixture becomes light and fluffy. This process is crucial; it incorporates air into the batter, contributing to the cake's rise. Next, crack in the eggs one at a time, beating just until blended after each addition. Remember, fresh, room-temperature eggs work best!
Combine Dry Ingredients with Wet Ingredients
In a separate bowl, whisk together the flour, baking powder, and salt. Gradually add this dry mixture to the butter-sugar mixture alternately with the milk, starting and ending with the flour. Mixing at low speed ensures everything is just combined, preventing overmixing, which can lead to a tough texture.
Add in Lime Zest and Juice
Stir in the vanilla extract, lime zest, and fresh Key lime juice. This is where the magic happens! The zesty lime adds a refreshing flavor that perfectly complements the richness of the cake.
Pour Batter into the Pan and Bake
Pour the batter into a greased and floured 10-inch solid tube pan. Bake in your preheated oven for 1 hour and 15 to 20 minutes or until a toothpick inserted into the center comes out clean. Let it cool in the pan for 15 minutes before inverting onto a wire rack.
Prepare the Frosting
While the cake cools, whisk together the powdered sugar, lime juice, water, melted butter, and vanilla until you achieve a smooth frosting consistency. This zesty frosting is the perfect finishing touch to your Key Lime Pound Cake.
Drizzle the Frosting on the Cooled Cake
Finally, scrape the frosting into a quart Ziploc bag, seal it, and snip off one corner. Now you’re ready to drizzle! Pour the frosting back and forth over the top of the cooled cake, allowing it to cascade down the sides for an appealing presentation.
And there you have it! A step-by-step guide to mastering a delightful Key Lime Pound Cake. The combination of zesty lime flavor with a moist, rich texture is sure to leave everyone asking for seconds. Happy baking, and don't forget to share your delicious results!

Key Lime Pound Cake with Berries

Baking Tips and Notes for Key Lime Pound Cake
Importance of Room Temperature Ingredients
Using room temperature ingredients is crucial for achieving a perfectly moist and tender key lime pound cake. When butter, eggs, and milk are at room temperature, they incorporate more easily, leading to a smooth batter that traps air efficiently during mixing. This helps the cake rise beautifully and results in a lighter texture.
Freshness of Baking Powder
Always check the freshness of your baking powder before you start baking. Baking powder that’s past its prime can lead to a dense and underwhelming cake. If you’re unsure, do a quick test by mixing a teaspoon of baking powder with hot water; it should fizz vigorously. If it doesn’t, it's time for a fresh batch!

These simple tips will set you up for success and make your key lime pound cake a delightful centerpiece for any gathering. Happy baking!
