Starbucks Lemon Loaf

  • Author: Olivia Chen
  • Total Time: 1 hour 10 minutes


1 1/2 cups all-purpose flour
1 1/2 tsp baking powder
1 Tbsp lemon zest
1/2 tsp salt
1/2 cup unsalted butter, room temperature
1 cup granulated sugar
2 large eggs, room temperature
1 tsp vanilla extract
2 Tbsp lemon juice
1/2 cup buttermilk


Preheat oven to 350°F (177°C) and grease a 5 x 9″ loaf pan.
In a medium bowl, combine the flour, baking powder, lemon zest, and salt. Set aside.
Using an electric mixer, cream the butter and sugar together at medium-high speed until fluffy, about 4-6 minutes. Scrape the sides of the bowl as needed.
Add the eggs one at a time, then beat in the vanilla extract and lemon juice. Beat on medium-high speed until combined.
Scoop in about one-third of the flour mixture and mix until almost combined, then add half the buttermilk and mix until combined. Repeat with another third of flour mixture and then the last half of the buttermilk, ending with the last third of the flour until fully combined.
Scoop the batter into the prepared loaf pan and bake for 45-55 minutes until the cake is golden brown and a toothpick comes out mostly clean. Baking times vary, so keep an eye on it.
Let the cake cool for about 15 minutes in the pan.
Stir together the lemon juice and confectioners’ sugar for the lemon syrup.
Carefully flip the loaf pan, and transfer the cake to a cooling rack, then brush the syrup on the top of the cake while it’s still warm.
Allow the cake to cool completely.


When the cake is cooled, combine all the icing ingredients. The icing should be thick and not runny. Pour icing over cake and let dry before serving.
