Why I Love This Recipe

There’s something magical about lime zest and juice when swirled into a tender pound cake batter. This recipe uses key lime juice for its distinct tart flavor, balanced by the creamy richness of sour cream. The glaze? Just a two-ingredient drizzle that adds even more zing. It’s sunshine in cake form—and ridiculously easy to make.

Ingredients

• 2 1/2 cups all-purpose flour
• 1/2 teaspoon baking soda
• 1/2 teaspoon salt
• 1 cup unsalted butter, room temperature
• 2 1/2 cups granulated sugar
• 6 large eggs
• 1/4 cup key lime juice
• 1 tablespoon lime zest
• 1 cup sour cream
• 1 teaspoon vanilla extract
• For the glaze:
  • 1 cup powdered sugar
  • 2–3 tablespoons key lime juice
  • Extra lime zest (optional, for garnish)

Swaps and Notes

• No key lime juice? Regular lime juice works in a pinch but won’t have quite the same floral zing.
• Greek yogurt can sub in for sour cream if needed.
• Add shredded coconut or even white chocolate chips for extra flair.

Step-by-Step Instructions

1. Preheat & Prep: Set oven to 350°F (175°C). Grease and flour a bundt or pound cake pan.
2. Dry Mix: Sift together flour, baking soda, and salt in a bowl.
3. Cream Butter & Sugar: Beat butter and sugar in a large bowl until light and fluffy (3–5 minutes).

Tips for Success

• Don’t overmix the batter—just combine until you no longer see streaks of flour.
• Use fresh lime zest for the most aromatic flavor.
• Make sure the cake is completely cool before glazing, or the drizzle may melt off.
