Starbucks Lemon Loaf Cake

Ingredients

  • 1 ½ cups all-purpose flour
  • 1 tsp baking powder
  • ½ tsp baking soda
  • ½ tsp salt
  • 3 large eggs
  • 1 cup granulated sugar
  • 2 tbsp unsalted butter, softened
  • 1 tsp vanilla extract
  • 2 tsp lemon extract
  • ⅓ cup fresh lemon juice
  • ½ cup vegetable oil
  • ½ cup plain Greek yogurt or sour cream
  • Zest of 1 lemon

For the Lemon Glaze:

  • 1 cup powdered sugar
  • 2–3 tbsp fresh lemon juice

Instructions

  1. Preheat your oven to 350°F (175°C). Grease and line a 9×5-inch loaf pan with parchment paper.
  2. In a medium bowl, whisk together flour, baking powder, baking soda, and salt. Set aside.
  3. In a large mixing bowl, beat eggs, sugar, and softened butter until light and fluffy.
  4. Mix in vanilla extract, lemon extract, lemon juice, lemon zest, vegetable oil, and yogurt (or sour cream) until smooth.
  5. Gradually fold the dry ingredients into the wet mixture until just combined—do not overmix.
  6. Pour batter into the prepared loaf pan and bake for 45–55 minutes, or until a toothpick inserted into the center comes out clean.
  7. Let the cake cool for at least 15 minutes before removing it from the pan.
  8. To make the glaze, whisk powdered sugar and lemon juice until smooth and pourable. Adjust thickness with more sugar or juice as needed.
  9. Drizzle the glaze over the cooled cake and allow it to set before slicing.

If you’d like, I can also give you a copycat version that’s extra moist like Starbucks makes by tweaking the oil-to-yogurt ratio. Would you like me to prepare that?
