This Key Lime Pound Cake Is a Slice of Sunshine You’ll Crave All Year Long
If you’re looking for a dessert that sings with citrus and feels like a tropical vacation in every bite, this Key Lime Pound Cake delivers just that. Moist, buttery, and perfectly balanced between sweet and tart, this cake is a crowd-pleaser at brunches, potlucks, or sunny afternoon teas.
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
- Preheat & Prep: Set oven to 350°F (175°C). Grease and flour a bundt or pound cake pan.
- Dry Mix: Sift together flour, baking soda, and salt in a bowl.
- Cream Butter & Sugar: Beat butter and sugar in a large bowl until light and fluffy (3–5 minutes).
- Add Eggs: Beat in eggs one at a time. Mix well after each addition.
- Flavor Boost: Stir in key lime juice, lime zest, vanilla, and sour cream until smooth.
- Combine: Gradually add the dry ingredients to the wet, mixing gently until just combined.
- Bake: Pour batter into pan and smooth the top. Bake for 60–70 minutes or until a toothpick comes out clean.
- Cool: Let cool in the pan 15 minutes, then turn out onto a rack to cool completely.
- Glaze It: Whisk together powdered sugar and lime juice. Drizzle over cooled cake. Garnish with zest if desired.
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.
Serving Suggestions & Pairings
Serve slices with a dollop of whipped cream, lime slices, and a few fresh berries. For drink pairings, this cake is dreamy alongside a tall glass of blueberry lemonade or a simple classic margarita if you’re feeling fancy.
Storage & Leftovers
