Key Ingredients
To create this airy, citrus-infused angel food cake, you’ll need just a handful of simple ingredients that work together to build volume, texture, and vibrant lime flavor.
- 1 cup cake flour: Provides a delicate crumb essential for the light, airy texture of the sponge.
- 1 1/4 cups granulated sugar: Sweetens the batter and helps stabilize the whipped egg whites for maximum volume.
- 12 large egg whites: The main leavening powerhouse, whipped to airy peaks for that classic sponge lift.
- 1 1/2 teaspoons cream of tartar: Stabilizes and strengthens the egg white foam to maintain structure and height.
- 1/4 teaspoon salt: Balances sweetness and enhances overall flavor depth.
- 1 teaspoon vanilla extract: Adds a warm, aromatic backdrop to the bright citrus notes.
- 2 tablespoons key lime zest: Infuses the cake with vibrant citrus oil and fragrant aroma.
- 4 tablespoons key lime juice: Delivers tangy acidity to brighten and balance the sweetness.
- 1 cup powdered sugar: Blended with lime juice for a silky glaze that crowns the cake.
How To Make Key Lime Angel Food Cake
From whipping egg whites to folding in zesty lime, this recipe transforms basic pantry staples into a cloudlike masterpiece. The key is to gently combine ingredients without deflating the foam and to bake just until golden, ensuring a tender crumb and uplifting lift. Ready your mixer, sift your flour, and let’s walk through each step for flawless results.
1. Preheat your oven to 350°F to ensure consistent baking temperature.
2. In a medium bowl, sift 1 cup cake flour and 1/4 cup granulated sugar together to remove lumps; set aside.
3. In a large bowl, beat 12 large egg whites with 1 1/2 teaspoons cream of tartar and 1/4 teaspoon salt until foamy and soft peaks begin to form.
4. Gradually add the remaining 1 cup granulated sugar while continuing to beat on medium-high speed until stiff, glossy peaks form.
5. Gently fold in 1 teaspoon vanilla extract, 2 tablespoons key lime zest, and 2 tablespoons key lime juice, keeping as much air in the batter as possible.
6. Pour the batter into an ungreased angel food cake pan, using a spatula to smooth the top evenly.
7. Bake for 35 minutes, or until the top is golden and springs back to the touch when gently pressed.
8. Invert the pan immediately and let the cake cool completely in the pan (about 1 hour) to maintain its height.
9. In a small bowl, whisk 1 cup powdered sugar with the remaining 2 tablespoons key lime juice until smooth.
10. Remove the cake from the pan and drizzle the lime glaze over the top before slicing and serving.

Tips For Perfect Key Lime Angel Food Cake
Mastering this cake is all about technique and ingredient quality. Here are a few insider pointers to help you get a tall, tender, and flavorful Key Lime Angel Food Cake every time:
- Use room temperature egg whites for better volume and a more stable foam.
- Do not grease the angel food cake pan—this allows the batter to climb the sides and rise fully.
- For best flavor, use fresh key limes for both zest and juice to capture that authentic tang.
- Store the cooled cake in an airtight container for up to two days to preserve its light texture.
How To Store It
Proper storage keeps the cake’s airy crumb and bright lime flavor intact for days. Whether you’re tucking leftovers away for later or planning ahead for a special event, these methods will help you preserve texture and taste.
- Room-Temperature Storage: Place cooled cake in an airtight container for up to two days to maintain its tender crumb.
- Refrigeration: Store in a loosely covered container in the fridge for up to three days; bring slices to room temperature before serving.
- Freezing: Wrap individual slices in plastic wrap and seal in a freezer bag for up to one month; thaw overnight in the refrigerator.
- Layer Protection: If stacking slices, separate each layer with parchment paper to prevent sticking and preserve texture.
Frequently Asked Questions
Here are answers to some common questions to help you achieve angelic results with every bake:
- How long does it take to prepare and bake this Key Lime Angel Food Cake?
From start to finish, plan on about 20 minutes to sift the flour, beat and fold the egg whites, and assemble the batter, then 35 minutes of baking, plus one hour of cooling inverted in the pan. In total, expect around two hours before you’re ready to glaze and serve.
- Why should I not grease the angel food cake pan?
Angel food cake relies on the batter clinging to the sides of the pan as it rises. Greasing the pan prevents the foam from gripping the walls, causing the cake to collapse and lose its characteristic height and airy texture.
- What’s the best way to achieve stiff peaks when beating the egg whites?
Use room-temperature egg whites in a completely clean, grease-free bowl. Add the cream of tartar and salt once the eggs are foamy, then gradually increase mixer speed. Slowly sprinkle in the sugar to stabilize the foam and continue beating until the peaks stand straight and hold their shape when you lift the beaters.
- Can I use regular limes instead of key limes for the zest and juice?
Yes, you can substitute regular limes if key limes aren’t available. The flavor will be slightly less tart and aromatic, so you may want to taste and adjust the juice and zest quantities to achieve a bright citrus balance similar to authentic key lime.
- How do I remove the cake from the pan without breaking it?
After the cake has completely cooled inverted, run a thin, non-serrated knife or an offset spatula around the inner and outer edges of the tube pan. Gently release the cake by lifting the sides, then turn the pan right-side up and let the cake slide onto a serving plate.
- What’s the best way to store leftover Key Lime Angel Food Cake?
Place the cake in an airtight container at room temperature for up to two days. Storing it this way preserves the light texture, while the key lime glaze may soften slightly but will continue to infuse the cake with its tangy flavor.
- How can I adjust the glaze if it’s too thick or too thin?
If the glaze is too thick to drizzle, whisk in small additional teaspoons of key lime juice until it reaches a pourable consistency. If it’s too thin and runs off the cake, sift in a little more powdered sugar, mixing until you have a smooth, clingy glaze that holds on the surface.
