Instructions
Prepare Your Ingredients and Pan
- Preheat your oven to 350°F (175°C) and grease a 9x13 inch baking pan or two 8-inch round cake pans.
- Wash and grate your zucchini using the fine holes of a box grater.
- Place the grated zucchini in a clean kitchen towel and gently squeeze out excess moisture.
- Zest your lemons before juicing them to get the freshest flavor.
Mix the Wet Ingredients
- In a large mixing bowl, whisk together the eggs, sugar, and vegetable oil until well combined.
- Add the fresh lemon juice, lemon zest, and vanilla extract to the mixture.
- Stir in the buttermilk until the mixture is smooth and well incorporated.
- Fold in the prepared zucchini, making sure it's evenly distributed throughout the wet ingredients.
Combine Dry Ingredients and Mix
- In a separate bowl, whisk together flour, baking powder, baking soda, and salt.
- Gradually add the dry ingredients to the wet mixture, stirring just until combined.
- Be careful not to overmix the batter, as this can result in a tough cake.
- The batter should be smooth with small pieces of zucchini visible throughout.
Bake to Perfection
- Pour the batter into your prepared pan and spread it evenly.
- Bake for 35-40 minutes for a 9x13 pan, or 25-30 minutes for round pans.
- Test for doneness by inserting a toothpick into the center; it should come out with just a few moist crumbs.
- Allow the cake to cool in the pan for 10 minutes before removing.

Zucchini Preparation Secrets:

- Add a pinch of lemon extract if you want an even more pronounced citrus taste
Baking Success Tips:

Grandma's Secret That Changed Everything
After years of making decent zucchini cakes, I discovered the game-changing secret that transforms this Lemon Zucchini Cake from good to absolutely incredible. The key lies in letting the grated zucchini sit with a pinch of salt for exactly 15 minutes before adding it to your batter; this draws out excess moisture while concentrating the vegetable's natural sweetness.
The second part of this magical technique involves adding the lemon juice in two stages; half goes into the wet ingredients as usual, but reserve a tablespoon to brush over the warm cake before applying the glaze. This double-lemon approach creates layers of citrus flavor that make each bite of Lemon Zucchini Cake burst with brightness and keeps people coming back for seconds every single time.
FAQ
Does zucchini cake need to be refrigerated?
Your Lemon Zucchini Cake can safely stay at room temperature for up to 3 days when stored in an airtight container. However, if you've added cream cheese frosting or live in a very humid climate, refrigeration will help maintain freshness and prevent spoilage.
Do you need to refrigerate a lemon cake?
A plain Lemon Zucchini Cake with simple glaze doesn't require refrigeration for the first few days, but the high moisture content from zucchini means it will stay fresher longer when refrigerated. The lemon's natural acidity also helps preserve the cake.
Why is my lemon cake so dense?
Dense Lemon Zucchini Cake usually results from overmixing the batter, using too much flour, or not properly measuring ingredients. Make sure to mix just until ingredients are combined and consider weighing your flour for more accurate measurements.
How long do lemon cakes last?
Your Lemon Zucchini Cake will maintain peak quality for 3-4 days at room temperature or up to one week when refrigerated. Properly wrapped cake can be frozen for up to 3 months without significant quality loss.
