- All-purpose Flour (1½ cups) – The main structure component; no substitutions recommended for effectiveness.
- Salt (½ teaspoon) – Balances sweetness and enhances the overall flavor.
- Baking Powder (1½ teaspoons) – Acts as the leavening agent that helps the bread rise.

How to Make Key Lime Quick Bread
-
Preheat your oven to 350°F (175°C) and grease a 9×5 loaf pan. This ensures your bread comes out easily once baked, with a lovely crust.
-
Cream together the softened butter and sugar in a medium bowl until it’s light and fluffy. This process may take about 2-3 minutes and is essential for a moist texture.
-
Mix in the eggs, key lime zest, lime juice, and vanilla extract until combined. The mixture should be smooth, with the zest evenly distributed for a burst of flavor in every bite.
-
Gradually add the all-purpose flour, baking powder, salt, and buttermilk. Stir until just mixed—be mindful not to overmix, as we want that soft, airy crumb!
-
Pour the batter into the prepared loaf pan, spreading it evenly across the bottom. You’ll want to create a nice, level top for even baking.
-
Bake for approximately 45 minutes, or until golden brown and a toothpick inserted comes out clean. Keep an eye on it towards the end to avoid overbaking.
-
Whisk together the powdered sugar and lime juice in a small bowl while the bread bakes. This glaze adds a delightful sweetness and ties together the tangy flavors beautifully.
-
Cool the bread in the pan for about 10 minutes after baking, then remove it and drizzle the glaze over while it’s still warm. This will allow the glaze to soak in slightly and enhance the flavor!
Optional: Garnish with extra lime zest for a zesty pop!

Expert Tips for Key Lime Quick Bread

Key Lime Quick Bread Recipe FAQs
What type of key limes should I use for this recipe?
Absolutely! Fresh key limes, typically smaller and more aromatic than regular limes, are best for this recipe. Look for key limes that are firm and heavy for their size, indicating juiciness. If you can’t find them, regular limes can be used as a substitute, just keep in mind that the flavor might be slightly different.
How should I store the Key Lime Quick Bread?
To keep your Key Lime Quick Bread fresh, store it in an airtight container at room temperature for up to 4 days. If you want to keep it longer, you can freeze it without the glaze. Wrapped tightly in plastic wrap (and then aluminum foil for extra protection), it will last in the freezer for up to 3 months.
Can I freeze the Key Lime Quick Bread?
Absolutely! To freeze, wait until the bread has completely cooled. Wrap it tightly in plastic wrap and then in aluminum foil. This helps prevent freezer burn. When you’re ready to enjoy it, simply thaw it in the refrigerator overnight and glaze it before serving.
Why did my Key Lime Quick Bread come out dense?
Very! A dense bread can result from overmixing the batter or not using room temperature ingredients. Be sure to mix just until incorporated and avoid overworking the flour, as this helps maintain that light and airy texture. If you’re unsure, a few lumps are perfectly fine!
Are there any dietary considerations I should be aware of?
Yes! If you’re making this bread for guests, keep in mind that it contains dairy and eggs, which might not be suitable for those with certain allergies. If you need a dairy-free alternative, you can replace the buttermilk with a non-dairy milk mixed with a bit of vinegar or lemon juice. Always check ingredient labels to ensure they meet your guests’ dietary needs!
Can I modify this recipe for a gluten-free version?
Very much so! You can substitute the all-purpose flour with a 1:1 gluten-free baking blend. Make sure your blend contains xanthan gum, which helps mimic the texture of regular flour. Just remember that baking times may vary, so keep an eye on it while it bakes!
