Ingredients
For the Cake
- 1 cup (2 sticks) unsalted butter, softened
- 2 cups granulated sugar
- 4 large eggs, room temperature
- Zest of 2 lemons
- ½ cup fresh lemon juice (about 2–3 lemons)
- 2 cups all-purpose flour
- 1 tsp baking powder
- ½ tsp salt
- 1 cup sour cream, room temperature
For the Lemon Syrup (Optional)
- ½ cup sugar
- ¼ cup lemon juice
- 1 tbsp vanilla extract
Note: The syrup adds extra moisture and flavor—ideal for humid climates!
Instructions
Step 1: Preheat & Prep
- Preheat oven to 350°F (175°C).
- Grease a 9×5 inch loaf pan with butter or non-stick spray. Line the bottom with parchment paper for easy removal.
Step 2: Cream Butter & Sugar
- In a large bowl, beat the butter and sugar with an electric mixer on medium-high speed for 3–4 minutes, until light, fluffy, and pale yellow.
Step 3: Add Eggs & Lemon
- Add eggs one at a time, beating well after each addition.
- Mix in lemon zest until evenly distributed.
Step 4: Combine Dry Ingredients
- In a separate bowl, whisk flour, baking powder, and salt.
- Gradually add dry ingredients to the butter mixture in three parts, alternating with ½ cup sour cream each time. Start and end with dry ingredients.
- Stir in lemon juice last, mixing just until combined. Overmixing = a tough cake!
Step 5: Bake
- Pour batter into the prepared pan, smoothing the top with a spatula.
- Bake for 60–70 minutes, or until a toothpick inserted into the center comes out clean. The top should be golden-brown.
Step 6: Cool & Syrup (Optional)
- Let the cake cool in the pan for 10 minutes, then transfer to a wire rack.
- While warm, brush the Lemon Syrup (if using) over the top to lock in moisture.
Step 7: Serve
- Slice with a serrated knife for clean cuts. Enjoy plain, with whipped cream, or a dusting of powdered sugar!
Notes
1. Room-Temperature Ingredients Matter
Cold butter or eggs will create a lumpy texture. Let butter soften for 30 minutes at room temp. Eggs should be out of the fridge for 10–15 minutes.
2. Lemon Substitutions
- No fresh lemon? Use ¼ cup bottled lemon juice + zest from 1 lemon (reduce juice to ½ cup total).
- Too much lemon? Cut juice to ¼ cup and add a pinch of ** baking soda** to balance acidity.
3. Sour Cream Alternatives
- Greek yogurt: Same moisture, tangier flavor.
- Buttermilk: Use 1 cup buttermilk + 1 tbsp vinegar if you don’t have buttermilk.
4. Avoiding a Dense Cake
- Don’t overmix after adding flour. Stir just until combined.
- Check doneness early: Ovens vary! Start testing at 55 minutes.
5. Storage
- Room temp: Store loosely covered for up to 3 days.
- Freeze: Wrap tightly in plastic wrap and foil for up to 3 months. Thaw overnight at room temp.
6. Gluten-Free Option
Swap all-purpose flour for 1:1 gluten-free flour blend (like Bob’s Red Mill). Add ½ tsp xanthan gum if your blend doesn’t include it.
