For the Cake:

  • 3 eggs
  • 2.5 cups all purpose flour
  • 2 cups sugar
  • 1 cup milk room temperature
  • 4 oz unsalted butter, room temperature one stick
  • 2 tsp baking powder
  • 1 Tbsp key lime zest* about 2 limes
  • 2 Tbsp key lime juice* about 2 limes
  • 1 tsp salt

For the Frosting:

  • 1x 14oz can sweet condensed milk
  • 1-2 Tbsp key lime zest* about 4 limes
  • 1/2 cup key lime juice* about 4 limes


For the Cake:

  • Preheat oven to 350F.
  • Spray, or grease and flour a bundt cake pan.
  • Add the all purpose flour, the baking powder and the salt to a large bowl, and whisk to combine – set aside.
  • Mix the butter and the sugar in a large bowl, using a hand mixer until it looks sandy. Then add in the eggs, one at a time, mixing until combined between each addition (a few minutes on medium speed).
  • Alternate adding flour mixture and the milk, beginning and ending with flour (3 additions of flour and 2 of milk), fully incorporating after each addition.
  • With a spatula, scrape the sides of the bowl and give it a stir. Then, add in the key lime juice and zest and stir to combine.
  • Pour the batter into the greased bundt pan, and bake until a cake tester/toothpick inserted to the middle comes out lightly crumbly to clean (about 35-40 mins)
  • Move the cake pan to a cooling rack and let it cool for about 5-10 mins, then remove the cake from the pan and let it cool on the rack

For the Frosting:

  • Add in the condensed milk and the key lime juice to a medium bowl.
  • Using a hand mixer, or a hand whisk**, whisk the mixture until creamy and frothy - about 3 minutes on high. Sprinkle in a little bit of the zest and gently stir it with a spatula.
  • Pour the lime cream over the cake, and sprinkle with the remaining key lime zest.

Bom Apetite!!


    *if you can't find key limes, regular limes will work fine!
    **you can also use a standing mixer with a whisk attachment, or even a blender.
