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
Preheat your oven to 325°F (165°C) . Grease and flour a loaf pan (9x5-inch) or line it with parchment paper for easy removal.
Step 2: Cream Butter and Sugar
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
Beat in the eggs one at a time, ensuring each egg is fully incorporated before adding the next.
Mix in the key lime zest and juice until well combined.
Step 4: Combine Dry Ingredients
In a separate bowl, whisk together the flour, baking powder, and salt.
Step 5: Alternate Wet and Dry Ingredients
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
Pour the batter into the prepared loaf pan and smooth the top with a spatula.
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.
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
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
Drizzle the glaze generously over the cooled cake. Sprinkle with additional lime zest for a pop of color and flavor.
Slice and serve with a cup of coffee, tea, or a scoop of vanilla ice cream.
