Step‑by‑Step Instructions for Key Lime Quick Bread
Step 1: Preheat the Oven
Start by preheating your oven to 350°F (175°C). While it warms, grease a 9×5 inch loaf pan to ensure your Key Lime Quick Bread releases easily once baked. This preparation is essential for achieving that beautifully golden crust we all love!
Step 2: Cream Butter and Sugar
In a medium mixing bowl, combine the softened unsalted butter and granulated sugar. Using a hand mixer or a whisk, cream these ingredients together until the mixture is light and fluffy, which should take about 2-3 minutes. The airy texture will help give your quick bread its desired lift!
Step 3: Add Wet Ingredients
Mix in the eggs one by one, ensuring they are fully incorporated before adding the key lime zest, key lime juice, and vanilla extract. Stir gently until the batter is smooth and uniform, allowing the bright citrus flavors to meld beautifully. This step is crucial to infusing your Key Lime Quick Bread with its signature taste.
Step 4: Incorporate Dry Ingredients
Gradually sprinkle in the all-purpose flour, baking powder, and salt, followed by the buttermilk. Stir the ingredients together gently, just until combined, taking care not to over-mix. A few lumps are perfectly fine; they will bake out, and over-mixing could lead to a denser bread.
Step 5: Transfer to Pan
Once your batter is well-combined, pour it into the prepared loaf pan. Use a spatula to smooth the top evenly, creating an inviting surface for even cooking. If you’d prefer smaller portions, consider dividing the batter into mini loaf pans or a muffin tin for bite-sized treats!
Step 6: Bake the Bread
Place the loaf pan in your preheated oven and bake for approximately 45 minutes. Your Key Lime Quick Bread is done when it turns a lovely golden brown, and a toothpick inserted into the center comes out clean. Keep an eye on it during the last few minutes for perfect doneness!
Step 7: Make the Glaze
While the bread is baking, prepare the glaze by whisking together powdered sugar with an additional splash of key lime juice in a small bowl. Aim for a smooth, pourable consistency. The glaze will add that final zesty touch to your Key Lime Quick Bread once it cools.
Step 8: Cool the Bread
When the baking time is complete, carefully remove the pan from the oven. Allow the bread to cool in the pan for about 10 minutes; this resting period makes it easier to transfer. Then, gently take the loaf out and place it on a cooling rack to cool completely.
Step 9: Glaze and Serve
Once your Key Lime Quick Bread has cooled slightly, drizzle the prepared glaze generously over the top. Let it set for a moment before slicing. This delightful treat is perfect for sharing at breakfast or enjoying with a cup of tea during the afternoon.

Expert Tips for Key Lime Quick Bread
-
Fresh Ingredients: Use fresh key limes for the best flavor. Old or bottled juice can result in a dull taste and weaken the vibrant zing of your Key Lime Quick Bread.
-
Avoid Over-Mixing: Mix the batter just until combined. Over-mixing can lead to a denser bread, so be gentle when adding the dry ingredients.
-
Check Doneness: If using mini loaf or muffin pans, start checking for doneness around 25-30 minutes. This ensures your Key Lime Quick Bread doesn’t overbake and remains moist.
-
Cool Before Glazing: Ensure the bread cools for about 10 minutes before adding the glaze. Glazing too soon can cause it to soak in rather than sit beautifully on top.
-
Experiment with Add-Ins: Feel free to add nuts or shredded coconut for an extra texture and flavor boost. Make your Key Lime Quick Bread uniquely yours!
