Ingredients

Scale
  • 1 cup (227g) unsalted butter, softened
  • 2 cups (400g) granulated sugar
  • 4 large eggs, room temperature
  • 3 cups (375g) all-purpose flour
  • 1/2 teaspoon baking powder
  • 1/2 teaspoon salt
  • 1 cup (240ml) 7-Up soda
  • 1 tablespoon fresh lemon zest
  • 1 tablespoon fresh lime zest
  • 1 teaspoon vanilla extract
  • For the Citrus Glaze:
  • 1 cup (120g) powdered sugar, sifted
  • 2 tablespoons fresh lemon juice
  • 2 tablespoons fresh lime juice
  • 1 teaspoon lemon zest (optional)

Instructions

  1. Preheat the oven to 325°F (163°C). Grease a 9×5-inch loaf pan with butter or non-stick spray and lightly dust with flour, tapping out the excess.
  2. In a large bowl, beat 1 cup softened unsalted butter and 2 cups granulated sugar with an electric mixer on medium speed until light, fluffy, and pale, about 4 to 5 minutes.
  3. Add 4 large eggs one at a time, beating well after each addition until fully incorporated.
  4. In a separate bowl, whisk together 3 cups all-purpose flour, 1/2 teaspoon baking powder, and 1/2 teaspoon salt.
  5. With the mixer on low, add the dry ingredients to the butter mixture in three parts, alternating with 1 cup of 7-Up soda, starting and ending with the dry ingredients. Mix each addition just until combined.
  6. Fold in 1 tablespoon lemon zest, 1 tablespoon lime zest, and 1 teaspoon vanilla extract gently with a spatula.
  7. Pour the batter into the prepared loaf pan and smooth the top with a spatula.
  8. Bake for 70–80 minutes, starting to check at 65 minutes by inserting a toothpick into the center. The toothpick should come out clean or with a few moist crumbs. The top should be golden but not overly browned.
  9. Let the cake cool in the pan for about 15 minutes, then transfer to a wire rack to cool completely.
  10. Meanwhile, whisk together 1 cup powdered sugar, 2 tablespoons fresh lemon juice, 2 tablespoons fresh lime juice, and optional 1 teaspoon lemon zest until smooth to make the glaze.
  11. Once the cake is completely cool, drizzle the citrus glaze evenly over the top.
  12. Slice and serve at room temperature. Store leftovers in an airtight container to keep moist.

Notes

Use room temperature butter and eggs for better mixing and lighter texture. Do not overmix after adding flour to avoid toughness. Start checking cake doneness at 65 minutes to prevent drying out. Let cake cool completely before glazing. If glaze is too thick, add water a teaspoon at a time. Tent cake with foil if browning too fast.
