Ingredients

Scale

For the Cake:

  • 2 cups cake flour, sifted

  • 1 ½ cups granulated sugar

  • ½ cup unsalted butter, softened

  • 3 large eggs, room temperature

  • ½ cup fresh key lime juice

  • 2 teaspoons lime zest, finely grated

  • 1 teaspoon baking powder

  • ¼ teaspoon salt

For the Glaze:

  • 1 cup powdered sugar

  • 2 tablespoons fresh lime juice

  • Optional: extra lime zest for topping


Instructions

  • Preheat oven to 350°F (175°C). Grease and flour a 9×13-inch baking pan.

  • In a large bowl, cream the butter and sugar until light and fluffy, about 3 minutes.

  • Add the eggs one at a time, mixing well after each. Stir in lime zest.

  • In a separate bowl, whisk together the flour, baking powder, and salt.

  • Add the dry ingredients to the butter mixture alternately with key lime juice, beginning and ending with the dry ingredients. Mix until just combined.

  • Pour batter into the prepared pan and smooth the top.

  • Bake for 30–35 minutes, or until golden and a toothpick inserted in the center comes out clean.

  • Cool in the pan for 10 minutes, then transfer to the fridge for 20 minutes.

  • Whisk powdered sugar and lime juice until smooth. Drizzle over the chilled cake.

  • Optional: Sprinkle with extra zest for garnish. Slice and serve!

Notes

  • For best results, use fresh key lime juice rather than bottled.

  • Do not overmix the batter after adding flour—this keeps the cake light and tender.

  • Refrigerating the cake before glazing helps the icing set perfectly.

  • To make dairy-free, use plant-based butter and dairy-free yogurt for added moisture.

  • You can bake this as cupcakes—just adjust the baking time to 18–20 minutes.
