Essential Ingredients for Key Lime Pound Cake
Grab these straightforward ingredients for your key lime pound cake recipe. They come together for that signature tender crumb and bold lime taste. Heres everything you need, listed precisely so you can shop and bake with confidence.
For the Key Lime Pound Cake:
- 1 cup butter, softened
- ½ cup vegetable shortening
- 3 cups granulated sugar
- 6 large eggs
- 3 cups all-purpose flour
- ½ teaspoon baking powder
- 1/8 teaspoon salt
- 1 cup milk
- 1 teaspoon vanilla extract
- ¼ cup key lime juice
- 1 teaspoon key lime zest
For the Key Lime Glaze:
- 1 cup powdered sugar
- 2 tablespoons key lime juice
- ½ teaspoon vanilla extract
One quick note: One cup of all-purpose flour weighs about 4.25 ounces. Spoon it into the cup and level it off without packing down for best results. Regular lime juice works fine if key lime is unavailable. This keeps your lime pound cake spot-on.
Simple Swaps for Special Diets
Want a dairy-free version? Swap butter for plant-based sticks and milk for almond milk. For gluten-free key lime pound cake, use a 1:1 gluten-free flour blend. These tweaks keep the moist crumb intact.
| Ingredient | Role in Cake | Substitution Idea |
|---|---|---|
| Butter + Shortening | Richness and tenderness | Vegan butter blend |
| Milk | Moisture balance | Non-dairy milk |
| Key lime juice | Tangy flavor | Regular lime juice |
How to Prepare the Perfect Key Lime Pound Cake: Step-by-Step Guide
Step 1: Preheat and Prep Your Pan
Start by preheating your oven to 325°F (163°C). Grease and flour a 10-inch tube pan thoroughly. Use vegetable shortening, butter plus flour, or baking spray for easy release. A 10-inch tube pan holds all this batter perfectly. If switching to a Bundt pan, dont overfill to avoid spills.
Step 2: Cream the Fats and Sugar
Beat the 1 cup softened butter and ½ cup vegetable shortening at medium speed until light and creamy. Gradually add 3 cups granulated sugar, beating until fluffy. This builds the base for your moist key lime pound cake with tangy lime glaze.
Step 3: Add the Eggs
Add 6 large eggs one at a time, mixing well after each. This keeps the batter smooth and emulsified.
Step 4: Mix Dry Ingredients
In a bowl, combine 3 cups all-purpose flour, ½ teaspoon baking powder, and 1/8 teaspoon salt. Set aside.
Step 5: Alternate Wet and Dry
Add the flour mixture and 1 cup milk alternately to the butter mix, starting and ending with flour. Mix just until blended.
Step 6: Fold in Flavors
Stir in 1 teaspoon vanilla extract, ¼ cup key lime juice, and 1 teaspoon key lime zest. Pour into your prepared pan.
Step 7: Bake to Perfection
Bake for about 1 hour 15 to 20 minutes. A wooden pick in the center should come out clean. Tent with foil loosely after one hour if browning too fast.
Step 8: Cool Properly
Cool in the pan 10 minutes, then turn out onto a wire rack to cool fully.
Step 9: Make and Add Glaze
Whisk 1 cup powdered sugar, 2 tablespoons key lime juice, and ½ teaspoon vanilla extract. Drizzle over the cooled key lime cake.
Thats your easy key lime pound cake recipe done! Serve slices plain or with whipped cream.
Dietary Substitutions to Customize Your Key Lime Pound Cake
Quick Vegan Adjustments
Swap butter and shortening for vegan versions. Use flax eggs (1 tbsp ground flax + 3 tbsp water per egg) for the 6 eggs. Almond milk replaces dairy milk perfectly. The glaze works with plant-based powdered sugar if needed.
Gluten-Free Tweaks
Go for a 1:1 gluten-free flour blend in place of all-purpose. Reduce bake time slightly and check doneness early. Your gluten free key lime pound cake recipe will have a tender crumb.
Lower Fat Options
Cut shortening and use more butter, or add yogurt for moisture. These keep the pound cake dense yet light.
- Protein boost: Add almond flour swap.
- Flavor twist: Extra zest for more zing.
Adapt for your needs and enjoy this versatile pound cake recipe.

FAQs: Frequently Asked Questions About Key Lime Pound Cake
Can I use regular limes or bottled lime juice instead of Key limes for Key Lime Pound Cake?
Yes. Substitute regular (Persian) lime juice or bottled lime juice on a 1:1 basis, but expect a milder aroma and slightly different tartness. For best flavor: use fresh juice when possible and add the zest of 1–2 limes (Key or Persian) to retain bright citrus notes. If using bottled juice, taste and reduce liquid elsewhere by 1–2 tablespoons if the recipe seems too thin. Link opportunity: add a page on lime substitutions and zest techniques to help readers choose.
What pan should I use and how full should I fill it for Key Lime Pound Cake?
A tube (angel food) or standard Bundt pan both work; a tube pan holds more batter and bakes more evenly. Fill pans no more than two-thirds full—leave about 1–2 inches of headroom to prevent overflow. For Bundt pans, aim for 1⁄2 to 2⁄3 full depending on capacity. Grease well with butter or shortening and dust with flour or use baking spray to help release the cake. If using a smaller loaf pan, reduce batter or bake in batches and adjust baking time.
What temperature and baking time should I use for Key Lime Pound Cake?
Bake at 325°F (160°C) for a dense, even crumb—expect 60–75 minutes for a tube or loaf pan. If you prefer a slightly quicker bake, 350°F (175°C) can work for 50–60 minutes but watch for overbrowning. Start checking at 50 minutes: a toothpick inserted in the center should come out with a few moist crumbs, not wet batter. If the top browns too quickly, tent with foil and continue baking until done.
How should I store Key Lime Pound Cake and can it be made ahead or frozen?
Store cooled cake in an airtight container at room temperature for 3–4 days. Refrigerate up to 1 week if it contains perishable glaze or citrus curd. To freeze, wrap the cooled cake tightly in plastic wrap, then foil; it keeps up to 6 months. Thaw overnight in the refrigerator or at room temperature for a few hours. Make-ahead tip: bake and freeze unglazed, then thaw and add glaze or whipped topping just before serving for best texture.
How should I measure flour and handle batter to avoid a dense Key Lime Pound Cake?
For consistent results, weigh flour: 1 cup all-purpose flour ≈ 120–125 grams. If measuring by cup, stir the flour, spoon it into the cup, and level with a straight edge—don’t scoop. Mix batter until ingredients are combined; avoid overmixing once flour is added to prevent a tough crumb. If your batter seems heavy, check that leavening and room-temperature ingredients were used; slight folding of beaten egg whites (if the recipe calls for them) can lighten texture.
