Ingredients

Scale

For the Cake:

  • 2 tbsp key lime juice (freshly squeezed)
  • 1 1/2 cups egg whites (from 1012 large eggs, at room temperature)
  • 1/2 tsp lime peel (finely grated)
  • 1 cup cake flour (sifted)
  • 1 1/2 cups granulated sugar
  • 1 1/2 tsp cream of tartar
  • 1/2 tsp salt

For the Glaze:

  • 1 cup powdered sugar
  • 3 to 4 tbsp key lime juice
  • 1 tsp lime zest

For the Whipped Cream:

  • 1 cup heavy cream (chilled)
  • 1/2 tsp lime zest
  • 1 tbsp sugar

Instructions

  1. Preheat the Oven: Begin by preheating your oven to 350°F (175°C) so that it reaches the proper temperature by the time your batter is ready for baking.
  2. Beat the Egg Whites: In the bowl of an electric mixer, combine 1 1/2 cups egg whites at room temperature, 2 tablespoons key lime juice, 1 1/2 teaspoons cream of tartar, 1/2 teaspoon salt, and 1/2 teaspoon finely grated lime peel. Beat on high speed until stiff, glossy peaks form, which stabilizes the mixture and creates an airy structure.
  3. Incorporate Sugar and Cake Flour: Lower the mixer speed to low and gradually add 1 1/2 cups granulated sugar, mixing until just combined. Then, gently sprinkle in 1 cup sifted cake flour and fold it in with a spatula carefully to avoid deflating the whipped egg whites. Pour the batter into an ungreased 9 or 10-inch angel food tube pan. Bake for 35-40 minutes until the cake is golden brown and springs back when lightly touched. Let the cake cool completely in the pan before removing.
  4. Prepare and Drizzle the Key Lime Glaze: In a small bowl, whisk together 1 cup powdered sugar, 3 to 4 tablespoons key lime juice, and 1 teaspoon lime zest until smooth. Use a skewer or fork to poke small holes in the top of the cooled cake, then drizzle the glaze evenly over it to allow the flavors to soak in deeply.
  5. Make the Lime Whipped Cream: In a large bowl, add 1 cup chilled heavy cream, 1 tablespoon sugar, and 1/2 teaspoon grated lime zest. Beat on high speed for 3-4 minutes until stiff peaks form and the cream becomes thick and creamy. Serve the whipped cream alongside or spread on top of the cake for a fresh, citrusy finish.

Notes

  • Make sure egg whites are at room temperature for maximum volume when whisking.
  • Do not grease the angel food cake pan to allow the batter to cling and rise properly.
  • Poking holes before glazing helps the cake absorb more flavor of the key lime glaze.
  • Use freshly squeezed key lime juice for the best and brightest lime flavor.
  • Allow the cake to cool completely before removing from the pan to prevent collapse or cracking.
