Ingredients You’ll Need

Serves 8–10

For the Pound Cake:

• 1 cup unsalted butter , softened
• 1 ½ cups granulated sugar
• 4 large eggs , at room temperature
• 2 tsp key lime zest (or regular lime zest if key limes aren’t available)
• 1 tbsp key lime juice (about 4–6 key limes or 1 regular lime)
• 2 ½ cups all-purpose flour
• 1 tsp baking powder
• ½ tsp salt
• 1 cup whole milk , at room temperature

For the Key Lime Glaze:

• 1 ½ cups powdered sugar
• 2–3 tbsp key lime juice (adjust for desired consistency)
• 1 tsp key lime zest (optional, for garnish)

Step-by-Step Instructions

Step 1: Preheat & Prep

1. Preheat your oven to 325°F (165°C) . Grease and flour a loaf pan (9×5-inch) or line it with parchment paper for easy removal.

Step 2: Cream Butter and Sugar

1. In a large mixing bowl, use a hand or stand mixer to cream the butter and sugar together until light and fluffy (about 2–3 minutes).

Step 3: Add Eggs and Lime Flavor

1. Beat in the eggs one at a time, ensuring each egg is fully incorporated before adding the next.
2. Mix in the key lime zest and juice until well combined.

Step 4: Combine Dry Ingredients

1. In a separate bowl, whisk together the flour, baking powder, and salt.

Step 5: Alternate Wet and Dry Ingredients

1. Gradually add the dry ingredients to the butter mixture in three parts, alternating with the milk (start and end with the dry ingredients). Mix just until combined—do not overmix.

Step 6: Bake

1. Pour the batter into the prepared loaf pan and smooth the top with a spatula.
2. Bake for 60–70 minutes , or until a toothpick inserted into the center comes out clean. If the top starts to brown too quickly, cover loosely with foil.
3. Let the cake cool in the pan for 10 minutes, then transfer it to a wire rack to cool completely.

Step 7: Make the Glaze

1. In a small bowl, whisk together the powdered sugar and key lime juice until smooth. Adjust the juice to achieve your desired consistency (thicker for drizzling, thinner for pouring).

Step 8: Glaze and Serve

1. Drizzle the glaze generously over the cooled cake. Sprinkle with additional lime zest for a pop of color and flavor.
2. Slice and serve with a cup of coffee, tea, or a scoop of vanilla ice cream.

Why This Recipe Works

• Key Lime Magic : The zest and juice infuse the cake with bright, tangy flavor without overpowering the sweetness.
• Butter-Rich Base : The pound cake’s classic buttery texture is enhanced by the citrus, creating a perfect balance of richness and refreshment.
• Glaze Perfection : The sweet-tart glaze ties everything together, adding moisture and a glossy finish.

Variations to Try

• Add Coconut : Stir shredded coconut into the batter or sprinkle it on top for a tropical twist.
• Lemon or Orange Swap : Use lemon or orange zest and juice if key limes aren’t available.
• Gluten-Free Option : Substitute all-purpose flour with a gluten-free flour blend.
• Mini Loaves : Divide the batter into mini loaf pans for cute, giftable cakes.
• Layer Cake : Double the recipe and bake in round pans for a zesty layer cake with lime filling.

Tips for Success

• Room Temperature Ingredients : Ensure butter, eggs, and milk are at room temperature for a smooth batter.
• Don’t Overmix : Overmixing can make the cake dense. Mix just until the ingredients are combined.
• Storage : Store leftovers in an airtight container at room temperature for up to 2 days or in the fridge for longer freshness.

Serving Suggestions

• Romantic Touch : Garnish with edible flowers or a dusting of powdered sugar for elegance.
• Brunch Staple : Pair with mimosas, yogurt parfaits, or fresh fruit for a light meal.
• Party Platter : Serve alongside other citrus desserts like lemon bars or orange tarts for variety.
