Key Lime Angel Food Cake Ingredients
For the Cake
- 1 cup cake flour (sifted) – Sifting helps lighten the flour, ensuring a fluffy texture in your Key Lime Angel Food Cake.
- 1 cup granulated sugar (divided) – Dividing the sugar allows for sweetening the egg whites and the batter separately for better volume and flavor.
- 12 large egg whites (at room temperature) – Room temperature egg whites whip up to a greater volume, which is essential for the cake’s airy structure.
- 1/4 teaspoon salt – A pinch of salt enhances the sweetness and balances flavors beautifully.
- 1 teaspoon cream of tartar – This stabilizes the egg whites, helping them maintain their structure when whipped.
- 1 teaspoon vanilla extract – Vanilla adds depth to the flavor profile of this light dessert.
- 1 tablespoon key lime juice (freshly squeezed) – Fresh juice brightens the cake with its zesty tang, making every bite refreshing.
- 1 teaspoon key lime zest (for flavor) – Zest gives an extra citrus punch, enhancing the overall key lime experience.
For the Topping
- 1 cup heavy cream (chilled) – Chilled cream whips up perfectly to create a luscious topping for your cake.
- 2 tablespoons powdered sugar – Powdered sugar sweetens the whipped cream without adding graininess, making it smooth and delightful.
- 1 teaspoon vanilla extract – Adding vanilla to the whipped cream elevates its flavor, harmonizing it with the cake.
- 1 tablespoon key lime juice (for drizzling) – Drizzling fresh key lime juice over the whipped cream adds a vibrant, tangy finish to each slice.
How to Make Key Lime Angel Food Cake
1. Preheat the oven to 350°F (175°C). This is the perfect temperature for our light and airy cake to rise beautifully in the oven.
2. Sift together 1 cup of cake flour and 1/2 cup of granulated sugar in a mixing bowl. This step ensures a fluffy texture by aerating the flour and mixing in sweetness.
3. Beat 12 large egg whites with 1/4 teaspoon salt and 1 teaspoon cream of tartar in a separate bowl until soft peaks form. The egg whites should look frothy and hold their shape just slightly.
4. Gradually add the remaining 1/2 cup of granulated sugar, continuing to beat until stiff peaks form. This mixture should be glossy, standing tall when you lift the beaters out.
5. Fold in the flour mixture, along with 1 teaspoon vanilla extract, 1 tablespoon freshly squeezed key lime juice, and 1 teaspoon key lime zest until just combined. Be gentle here to keep that airy texture intact!
6. Pour the batter into an ungreased 9-inch round cake pan. Ensure it’s evenly spread for uniform baking—this will help it rise evenly.
7. Bake for 30-35 minutes or until the cake is golden and springs back when touched lightly on top. You’ll know it’s done when it has that lovely golden hue!
8. Remove from the oven and invert the pan to cool completely upside down. This allows air to circulate under the cake, preventing it from collapsing as it cools.
For the Topping:
9. Whip 1 cup of chilled heavy cream in a mixing bowl until soft peaks form, creating a cloud-like texture that’s perfect for our cake.
10. Add 2 tablespoons of powdered sugar and 1 teaspoon vanilla extract, continuing to whip until stiff peaks form. This sweetened cream will perfectly complement our tangy cake.
11. Once cool, remove the cake from the pan and top it generously with whipped cream, creating a luscious layer that everyone will love.
12. Drizzle with an additional tablespoon of key lime juice before serving for that extra zing! Your guests will be delighted by this refreshing finish.
Optional: Garnish with lime slices or zest for an extra pop of color!

Pro Tips for Key Lime Angel Food Cake
- Room Temperature Eggs: Use egg whites at room temperature to achieve the best volume when beating. This helps create that signature light texture.
- Sift Flour Twice: Sifting the cake flour not only removes lumps but also aerates it, giving your Key Lime Angel Food Cake a lighter, fluffier crumb.
- Gentle Folding: When incorporating the flour mixture, fold gently to maintain airiness. Overmixing can deflate your batter and result in a denser cake.
- Cool Upside Down: Invert the pan immediately after baking to prevent the cake from collapsing as it cools. This keeps it fluffy and airy.
- Chill Your Cream: Ensure your heavy cream is chilled before whipping; this helps achieve stiff peaks quickly for a perfect topping.
- Fresh Key Limes: Use freshly squeezed key lime juice for the best flavor. Bottled juices can lack the vibrant tang that makes this dessert so special.
How to Store and Freeze Key Lime Angel Food Cake

- Room Temperature: Keep your Key Lime Angel Food Cake covered with a clean kitchen towel for up to 1 day to maintain its airy texture.
- Fridge: For longer storage, wrap the cake in plastic wrap and place it in the fridge for up to 3 days. This helps preserve moisture while keeping it fresh.
- Freezer: If you’d like to enjoy your cake later, slice it and wrap individual pieces tightly in plastic wrap before placing them in an airtight container. It can be frozen for up to 2 months.
- Topping Storage: Whipped cream should be made fresh, but any leftovers can be stored in the fridge for up to 2 days in an airtight container.

Key Lime Angel Food Cake Recipe FAQs
What type of flour should I use for the Key Lime Angel Food Cake?
You’ll want to use cake flour for this recipe, as it creates that light and airy texture we all love in angel food cakes. Sifting it before measuring ensures there are no lumps and helps incorporate air, making your cake even fluffier.
Can I substitute the egg whites with something else?
While traditional angel food cake relies heavily on egg whites for its structure, you can try using aquafaba (the liquid from canned chickpeas) as a vegan alternative. You’ll need about 1.5 times the amount of aquafaba—roughly 18 tablespoons will replace the 12 large egg whites!
How should I store leftover Key Lime Angel Food Cake?
To keep your cake fresh, store it in an airtight container at room temperature. It will stay delicious for about 2-3 days. If you’d like to keep it longer, consider refrigerating it, but note that refrigeration can affect its light texture.
Can I freeze Key Lime Angel Food Cake?
Absolutely! You can freeze the unglazed cake for up to 2 months. Wrap it tightly in plastic wrap and then foil to prevent freezer burn. When you’re ready to enjoy it, simply let it thaw at room temperature before topping it with whipped cream and key lime drizzle.
How many servings does this recipe make?
This delightful Key Lime Angel Food Cake yields about 4 servings. Each slice is approximately 180 calories, making it a refreshing treat that won’t weigh you down!
What if my cake didn’t rise properly?
If your cake didn’t rise as expected, check a couple of things: ensure your egg whites were at room temperature and whipped to stiff peaks—this is crucial for volume. Also, be sure not to overmix when folding in the flour mixture; gentle folding retains the air you’ve whipped into those egg whites!
