Ingredients
  

For the cake
  • 3 cups all-purpose flour Simple yet essential for that perfect texture.
  • 1/2 teaspoon baking powder Helps the cake rise beautifully.
  • 1/2 teaspoon salt A little pinch always enhances flavors.
  • 1 1/2 cups unsalted butter, softened For a rich, creamy taste.
  • 3 cups granulated sugar Sweetness that balances the tartness.
  • 6 large eggs, room temperature Ensures a smooth batter.
  • 1 cup sour cream or whole milk Adds moistness and richness; prefer sour cream!
  • 1/4 cup fresh key lime juice The star of the show for bright flavor.
  • 2 tablespoons key lime zest This brings the flavor to life.
  • 2 teaspoons vanilla extract For that warm, comforting note.
For the glaze
  • 1 1/2 cups powdered sugar Sweetens things up at the end.
  • 2-3 tablespoons key lime juice Keeps the glaze tangy.
  • 1 teaspoon key lime zest A finishing touch of brightness.

Method
 

Preparation
  1. Preheat the oven to 325 degrees F (165 degrees C). Grease and flour a bundt or tube pan thoroughly.
  2. In a medium bowl, whisk together the flour, baking powder, and salt.
  3. In a large mixing bowl, beat the softened butter until creamy. Gradually add in the sugar, continuing to beat until light and fluffy, about 3 minutes.
  4. Add the eggs, one at a time, beating well after each addition.
  5. Mix in the sour cream (or milk), key lime juice, zest, and vanilla.
  6. Gradually mix in the dry ingredients until just combined.
  7. Pour the batter into the prepared pan, smoothing the top gently.
Baking
  1. Bake until a toothpick comes out clean, about 60 to 70 minutes.
Glazing
  1. While your cake cools, whisk together the powdered sugar, key lime juice, and zest for the glaze.
  2. When the cake is completely cool, drizzle the glaze over it.

Notes

For a quick option, use milk instead of sour cream. If your cake sinks, it might be due to overmixing—mix just until combined. Try adding chopped macadamia nuts or a hint of coconut for a tropical twist.
