Ingredients

• 2 1/2 cups cake flour
• 1 1/2 teaspoons baking powder
• 3/4 teaspoons baking soda
• 1 teaspoon salt
• 1/2 cup olive oil
• 1/2 cup unsalted butter, melted and cooled
• 1 cup whole milk
• 2 cup granulated sugar
• 4 large eggs, room temperature
• 3 tablespoons key lime juice
• 2 tablespoons key lime zest
• 1 1/2 teaspoons vanilla extract
• 1/2 cup unsalted butter, softened
• 1 (8-ounce) box cream cheese, softened and cut into small cubes
• 1 tablespoon key lime juice
• 1 teaspoon key lime zest
• 1-2 pinches salt
• 4 1/2-5 cups powdered sugar

Instructions

1. 1

   Preheat oven to 350° F. Grease a 9x13 inch metal baking pan.

2. 2

   Whisk the cake flour, baking powder, baking soda, and salt together in a medium bowl.

3. 3

   In a large bowl, combine the olive oil, melted butter, milk, granulated sugar, eggs, key lime juice, key lime zest, and vanilla extract.

4. 4

   Stir the flour mixture into the egg mixture in two increments until combined. Don't overmix.

5. 5

   Pour the batter into the prepared pan. Bake for 25-32 minutes or until a toothpick inserted in the center comes out clean. Allow the cake to cool for several hours.

6. 6

   Using a stand mixer with a paddle attachment or a handheld mixer, beat the butter until smooth. Beat in the cream cheese until smooth. Add the key lime juice, zest, and salt. Add enough powdered sugar to reach the desired consistency. I start with 3 cups and then add ½ cup at a time until I reach the desired consistency.
