Ingredients

Scale

Cake Ingredients

  • 2 cups all-purpose flour
  • 1 cup granulated sugar
  • 2 large eggs
  • 1/2 cup lime juice (freshly squeezed)
  • 1/2 cup unsalted butter, softened
  • 1 tsp baking powder
  • 1/2 tsp baking soda
  • 1/4 tsp salt
  • 3/4 cup buttermilk

Glaze Ingredients

  • 1 cup powdered sugar
  • 2 tbsp lime juice (freshly squeezed)
  • 1 tsp lime zest (optional)

Instructions

  1. Preheat oven: Preheat your oven to 350°F (175°C). Grease and flour a 9×13 inch sheet cake pan.
  2. Mix dry ingredients: In a medium bowl, sift together the flour, baking powder, baking soda, and salt. Set aside.
  3. Cream butter and sugar: In a large mixing bowl, beat the softened butter and granulated sugar together until light and fluffy, about 3-4 minutes.
  4. Add eggs and lime juice: Beat in the eggs one at a time, then mix in the lime juice until well combined.
  5. Combine wet and dry ingredients: Alternately add the dry ingredients and buttermilk to the butter mixture, starting and ending with the dry ingredients. Mix just until combined; do not overmix.
  6. Pour batter into pan: Spread the batter evenly into the prepared sheet cake pan.
  7. Bake the cake: Bake in the preheated oven for 30-35 minutes, or until a toothpick inserted into the center comes out clean.
  8. Prepare the glaze: In a small bowl, whisk together powdered sugar and lime juice until smooth. If desired, add lime zest for extra flavor.
  9. Apply glaze: While the cake is still warm, drizzle the lime glaze over the top so it soaks in and forms a shiny, flavorful topping.
  10. Cool and serve: Allow the cake to cool completely before slicing into squares. Serve chilled or at room temperature.

Notes

  • For extra lime flavor, add 1 teaspoon of lime zest to the cake batter.
  • The glaze consistency can be adjusted by adding more lime juice for a thinner glaze or more powdered sugar for a thicker glaze.
  • This cake can be stored covered in the refrigerator for up to 4 days.
  • Use fresh lime juice for the best tart and authentic flavor.
