🧾 Ingredients
For the Lemon Loaf:

1½ cups (195g) all-purpose flour
-
½ teaspoon baking powder
-
½ teaspoon baking soda
-
½ teaspoon salt
-
3 large eggs (room temperature)
-
1 cup (200g) granulated sugar
-
½ cup (120ml) sour cream (full fat, room temp)
-
½ cup (120ml) vegetable oil (or melted butter for richer flavor)
-
2 tablespoons lemon zest (from about 2 lemons)
-
¼ cup (60ml) fresh lemon juice
-
1 teaspoon pure vanilla extract
-
1 teaspoon lemon extract (optional, but gives a strong lemony punch like Starbucks)

🍰 Instructions
1. Preheat and Prepare Pan
-
Preheat your oven to 350°F (175°C).
-
Grease and line a 9×5-inch loaf pan with parchment paper, leaving overhang on the long sides for easy removal.
2. Mix Dry Ingredients
In a medium bowl, whisk together:
-
Flour
-
Baking powder
-
Baking soda
-
Salt
Set aside.
3. Mix Wet Ingredients
In a large bowl, whisk together:
-
Eggs
-
Sugar
-
Sour cream
-
Oil
-
Lemon zest
-
Lemon juice
-
Vanilla extract
-
Lemon extract (if using)
Whisk until smooth and creamy.
4. Combine
-
Add the dry ingredients to the wet mixture.
-
Stir gently just until combined — do not overmix (this keeps the loaf tender and moist).
5. Bake
-
Pour batter into the prepared pan and smooth the top.
-
Bake for 50–60 minutes, or until a toothpick inserted into the center comes out clean or with a few moist crumbs.
-
If the top browns too quickly, tent loosely with foil around the 40-minute mark.
6. Cool
-
Allow the loaf to cool in the pan for 15–20 minutes.
-
Then lift it out using the parchment and transfer to a wire rack to cool completely before glazing.
7. Make the Glaze
-
In a small bowl, mix powdered sugar with lemon juice (and lemon extract if using).
-
Stir until smooth. The glaze should be thick but pourable. Add more lemon juice for thinner glaze.
8. Glaze the Loaf
-
Once the loaf is completely cool, pour the glaze over the top.
-
Let it set for 20–30 minutes before slicing.
🍽️ Serving Tips
-
Serve at room temperature.
-
Great with tea, coffee, or fresh berries.
🧊 Storage
-
Room Temp: Store in an airtight container for up to 3 days.
-
Fridge: Up to 5 days, tightly wrapped.
-
Freeze: Freeze the unglazed loaf (whole or sliced) for up to 2 months. Thaw and glaze before serving.
📝 Pro Tips
-
Don’t skip the lemon extract if you want that signature Starbucks lemon punch.
-
Use fresh lemons for juice and zest — bottled lemon juice won’t deliver the same brightness.
-
For a more buttery version, replace the oil with ½ cup melted unsalted butter, cooled.
