- 2 cups granulated sugar
- 4 large eggs, at room temperature

- 2 tablespoons key lime zest (about 8-10 key limes)

Step-by-Step Instructions
-
Step 1: Prepare Your Pan and Oven
Preheat your oven to 325°F (160°C). Grease and flour a 9×5 inch loaf pan thoroughly. You can also line it with parchment paper, leaving an overhang on the long sides to easily lift the cake out later.
Small tip: A light spray of non-stick baking spray with flour helps prevent sticking and ensures a beautiful release.
-
Step 2: Whisk Dry Ingredients
In a medium bowl, whisk together the all-purpose flour, baking powder, and salt. Make sure there are no lumps and the ingredients are well combined. Set this bowl aside for later.
-
Step 3: Cream Butter and Sugar
In a large mixing bowl, using an electric mixer, cream together the softened butter and granulated sugar until light and fluffy. This usually takes about 3-5 minutes. Scrape down the sides of the bowl as needed.
Small tip: Softened butter should be pliable but still cool to the touch, not melted.
-
Step 4: Add Eggs Gradually
Add the eggs one at a time to the butter mixture, beating well after each addition. Ensure each egg is fully incorporated before adding the next. This helps create a smooth, emulsified batter.
-
Step 5: Combine Wet Ingredients
In a separate small bowl, whisk together the buttermilk, key lime juice, key lime zest, and vanilla extract. This creates a flavorful liquid mixture ready to be added to the batter.
-
Step 6: Alternate Dry and Wet Ingredients
With the mixer on low speed, gradually add the dry ingredient mixture to the wet mixture, alternating with the buttermilk mixture. Start and end with the dry ingredients. Mix until just combined, being careful not to overmix.
Small tip: Overmixing can develop the gluten in the flour too much, leading to a tough cake. Mix until just no streaks of flour remain.
-
Step 7: Fill the Pan and Bake
Pour the batter evenly into your prepared loaf pan. Gently tap the pan on the counter a couple of times to release any large air bubbles. Place it into the preheated oven.
-
Step 8: Bake Until Golden
Bake for 60-70 minutes, or until a wooden skewer or toothpick inserted into the center of the cake comes out clean. The top should be golden brown and spring back when lightly touched. Cooking times can vary, so keep an eye on it!
-
Step 9: Cool the Cake
Once baked, remove the cake from the oven and let it cool in the pan for about 15-20 minutes. This allows the cake to firm up before you remove it. Then, carefully invert it onto a wire rack to cool completely.
Small tip: Cooling completely on a wire rack prevents the bottom of the cake from getting soggy.
-
Step 10: Prepare the Glaze
While the cake cools, prepare the key lime glaze. In a small bowl, whisk together the powdered sugar, key lime juice, and key lime zest until smooth. The consistency should be pourable but not too thin.
-
Step 11: Glaze the Cooled Cake
Once the pound cake is completely cool, drizzle the key lime glaze generously over the top. Let the glaze drip down the sides for a beautiful, rustic look. If you like a thicker glaze, you can apply a second coat after the first has set slightly.
-
Step 12: Garnish and Serve
Optionally, sprinkle with extra key lime zest or place thin key lime slices on top for a lovely presentation. Slice and serve your delicious Key Lime Pound Cake. Enjoy!
Tips & Variations
- Gluten-Free Option: To make this pound cake gluten-free, simply substitute the all-purpose flour with a 1:1 gluten-free baking flour blend. Ensure your chosen blend contains xanthan gum for best results.
- Vegan Option: For a delicious vegan version, use a plant-based butter substitute (like Miyoko’s Kitchen or Earth Balance sticks), replace the eggs with flax eggs (1 tbsp ground flaxseed + 3 tbsp water per egg, let sit for 5 min), and use plant-based buttermilk (dairy-free milk with a splash of apple cider vinegar). The texture will be slightly different but still wonderful.
- Add More Protein: Boost the protein content by incorporating 1/4 cup of unflavored or vanilla protein powder into your dry ingredients. You can also make a protein-rich cream cheese glaze using light cream cheese, a scoop of vanilla protein powder, a touch of key lime juice, and a little sweetener.
- Spicy Version: For a delightful twist, add 1/4 teaspoon of ground ginger or a tiny pinch of cayenne pepper to your dry ingredients for a subtle warmth. You could also add a very small amount of finely grated fresh ginger to the glaze for an extra zing.
- Other Flavor Tips: Experiment with other citrus! Lemon or orange zest and juice can be used instead of key lime for a different citrus pound cake. You can also fold in 1/2 cup of shredded coconut into the batter for a tropical key lime-coconut flavor.

Health Benefits
While this is a delightful dessert, some of its key ingredients offer surprising benefits!
Key Limes: These tiny powerhouses are packed with Vitamin C, a crucial antioxidant that supports your immune system and skin health. They also contain flavonoids, which have anti-inflammatory properties, adding a little health boost to every zesty bite.
Eggs: Eggs are an excellent source of high-quality protein, which is essential for muscle repair and growth. They also provide important vitamins like B12, D, and choline, which supports brain health. Eating eggs in moderation can be a nutritious part of your diet.
Buttermilk: While often overlooked, buttermilk is a good source of calcium and probiotics (if cultured), which can contribute to bone health and a healthy gut microbiome. It also helps create a wonderfully tender and moist crumb in baked goods.
Homemade Goodness: Baking at home means you control the ingredients. You avoid artificial flavors, preservatives, and excessive amounts of high-fructose corn syrup often found in store-bought cakes. Plus, the joy and satisfaction of baking can be a wonderful stress reliever!
Serving Suggestions
- Serve a slice with a dollop of freshly whipped cream or a scoop of vanilla bean ice cream for an extra indulgent treat.
- This pound cake is perfect as the star dessert for a brunch, afternoon tea, or a summer potluck. It pairs beautifully with a hot cup of coffee or a refreshing glass of iced tea.
- For a lighter touch, serve individual slices with a side of fresh berries like raspberries or blueberries. Their tartness complements the key lime perfectly.
Storage Tips
Your Key Lime Pound Cake will keep well at room temperature, covered tightly, for 2-3 days. For longer storage, you can keep it in an airtight container in the refrigerator for up to 5-7 days. This cake also freezes beautifully! Wrap individual slices or the entire cooled, unglazed cake tightly in plastic wrap, then in foil. It can be frozen for up to 2-3 months. To reheat, simply thaw at room temperature or warm gently in the microwave for a few seconds until soft.
