Bright, tangy Key Lime Pound Cake with a rich, ultra-moist crumb and a glossy citrus glaze. Every slice bursts with fresh lime juice and fragrant zest for a sunshine-in-a-bite moment. It’s the one I keep sneaking slivers of while it cools.

Instructions

Preheat the oven to 300℉.

Grease and flour a 9-10 inch Bundt cake pan.

Beat the sugar, butter, and shortening with an electric mixer in a large bowl until light and fluffy.

Whisk together the flour and baking powder in a separate bowl.

Beat the eggs, heavy cream, key lime juice, lime zest, and vanilla extract into the butter mixture.

Beat in the flour mixture just until combined.

Pour the batter into the prepared pan.

Bake at 300℉ for 1 hour and 30 minutes or until a toothpick inserted into the center comes out clean.

Cool in the pan on a wire rack for 15 minutes. Remove the cake from the pan to cool completely.

When the cake is cooled, make the glaze.

Glaze

In a bowl, whisk the powdered sugar, key lime juice, and vanilla extract.

Tips & Tricks (5)

Zest Before Juicing 🍋
Always zest your key limes before juicing to capture maximum citrus flavor and prevent losing those fragrant oils. Use a microplane for the finest, most delicate zest.
Room Temperature Ingredients 🌡️
Allow eggs, butter, and cream to sit at room temperature for 30-45 minutes before mixing to ensure a smoother, more even pound cake batter with better volume.
Glaze Consistency Trick 💧
For the perfect glaze, gradually add powdered sugar to key lime juice, whisking until it reaches a slow-flowing consistency that coats the back of a spoon.
Pan Preparation Pro 🧈
Create a foolproof non-stick surface by greasing the pan with shortening, then dusting with flour, ensuring your pound cake releases cleanly every time.
Moisture Preservation Hack 💦
Wrap the cooled cake in plastic wrap immediately after it reaches room temperature to lock in moisture and intensify the lime flavor overnight.
