It works perfectly for anyone who wants a not-too-sweet dessert or brunch treat that comes together in about 20 minutes of prep and about 45 minutes in the oven. I baked a version of this cake for a neighbor once, and she “forgot” to return the pan for three days because her family kept slicing off “just one more piece.”

Ingredients You’ll Need
Dry ingredients
- 2 cups (240 g) all-purpose flour
- Use a good-quality unbleached flour for the best texture.
- 1 ½ teaspoons baking powder
- ½ teaspoon baking soda
- ½ teaspoon fine sea salt
Wet ingredients
- 2 large eggs, room temperature
- 1 cup (200 g) granulated sugar
- ½ cup (120 ml) neutral oil
- Canola, vegetable, or light olive oil all work. I prefer canola for a clean flavor.
- ¼ cup (60 g) plain Greek yogurt or sour cream
- This adds richness and tenderness. Full fat works best.
- 2 tablespoons milk
- Any dairy milk works. Use whole milk for extra richness.
- 2 tablespoons fresh lemon juice
- 1 tablespoon finely grated lemon zest
- Use unwaxed lemons if possible and zest only the yellow part.
- 1 teaspoon vanilla extract
- Real vanilla tastes better than imitation, but use what you have.
Zucchini
- 1 ½ cups finely grated zucchini, lightly packed (about 1 medium zucchini)
- Do not peel the zucchini. The green flecks look pretty and stay very soft.
- Pat the grated zucchini gently with paper towels to remove excess moisture, but do not squeeze it dry or the cake turns dense.
Sweet lemon glaze
- 1 ¼ cups (150 g) powdered sugar, sifted
- Sifting avoids lumpy glaze.
- 2–3 tablespoons fresh lemon juice
- 1 tablespoon milk or cream
- ½ teaspoon lemon zest (optional, for extra zing)
Optional add-ins
- ½ cup mini white chocolate chips
- These melt slightly and add creamy sweetness that pairs nicely with lemon.
- ¼ teaspoon almond extract
- This gives the cake a bakery-style aroma. Use it with or instead of vanilla.
Equipment list
- 9 x 5 inch loaf pan or 8 inch square pan
- A metal pan bakes more evenly than glass.
- Parchment paper
- Line the pan for easy removal and cleaner slices.
- Two mixing bowls
- Whisk and rubber spatula
- Box grater or food processor with grating disc for the zucchini
- Cooling rack
- Microplane or fine grater for the lemon zest
Tips & Tricks
- Grate the zucchini on the fine side of the box grater so it melts into the batter and keeps the cake extra moist.
- Blot the zucchini gently with paper towels; leave a little moisture so the cake stays tender.
- Use room temperature eggs and yogurt so the batter mixes smoothly and rises evenly.
- Zest the lemon before you juice it, since whole lemons feel easier to handle.
- Whisk the dry ingredients separately so the baking powder and baking soda distribute evenly.
- Stir the batter just until no dry streaks of flour remain; overmixing makes the cake tough.
- Line the pan with parchment and leave a little overhang so you can lift the cake out easily.
- Check the cake a few minutes early; every oven runs a bit different and you want a moist crumb, not a dry loaf.
- Pour the sweet lemon glaze over the cake while it still feels slightly warm so it soaks in and sets shiny on top.
- Slice the cake with a sharp serrated knife once it cools completely to keep the slices neat.
How to Make Lemon Zucchini Cake With Sweet Lemon Glaze
Step 1: Prep the pan and oven
Preheat your oven to 350°F (175°C). Grease your loaf or square pan lightly with oil or butter, then line it with parchment paper and leave a little overhang on the long sides. This setup keeps the cake from sticking and makes removal simple.
Step 2: Grate and prep the zucchini
Wash and dry the zucchini, then trim off the ends. Grate it on the fine side of a box grater or use a food processor with a fine grating disc. Spread the grated zucchini on a clean kitchen towel or paper towels and pat the top with more towels to soak up excess moisture, then set it aside.
Step 3: Mix the dry ingredients
In a medium bowl, whisk together the flour, baking powder, baking soda, and salt. Break up any little clumps of flour as you whisk. Set this bowl near your mixing area so you can add it easily later.
Step 4: Whisk the wet ingredients
In a large bowl, whisk the eggs and sugar until the mixture looks slightly pale and thick. Add the oil, yogurt or sour cream, milk, lemon juice, lemon zest, vanilla, and any almond extract if you use it. Whisk until everything looks smooth and creamy.
Step 5: Combine wet and dry
Add the dry ingredients to the wet ingredients in two additions. Stir gently with a spatula after each addition until the flour almost disappears. Stop stirring as soon as you see no dry streaks, since extra mixing builds gluten and makes the cake less tender.
Step 6: Fold in the zucchini
Add the grated zucchini and any mini white chocolate chips if you use them. Fold gently until the zucchini spreads evenly through the batter. The batter should look thick but scoopable and slightly speckled with green.
Step 7: Fill the pan and bake
Pour the batter into the prepared pan and smooth the top with a spatula. Tap the pan lightly on the counter to pop any large air bubbles. Place the pan in the center of the oven and bake for 40 to 50 minutes, until a toothpick inserted in the center comes out with a few moist crumbs but no wet batter.
Step 8: Cool the cake
Place the pan on a cooling rack and let the cake cool in the pan for about 10 to 15 minutes. Lift the cake out using the parchment overhang and set it directly on the rack. Let it cool until just slightly warm before you add the sweet lemon glaze.
Step 9: Mix the sweet lemon glaze
In a small bowl, whisk the powdered sugar with 2 tablespoons of lemon juice and the milk or cream. Add more lemon juice a teaspoon at a time until you reach a thick but pourable consistency. Stir in the lemon zest if you want extra citrus flavor.
Step 10: Glaze and finish
Place a sheet of parchment or a tray under the cooling rack to catch drips. Pour the sweet lemon glaze slowly over the top of the warm cake, letting it drip down the sides. Let the glaze set for at least 20 to 30 minutes, then slice and serve.
What to Serve with Lemon Zucchini Cake With Sweet Lemon Glaze
Serve Lemon Zucchini Cake With Sweet Lemon Glaze with a cup of hot coffee, black tea, or herbal tea for a cozy afternoon treat. Add a spoonful of vanilla yogurt or a dollop of lightly sweetened whipped cream for a brunch-style plate. Fresh berries, especially blueberries or raspberries, taste amazing with the bright lemon flavor and add a pretty pop of color. Kids usually love a slice with a glass of cold milk or a lemony sparkling water.

Ingredients
Instructions
- Preheat the oven to 350°F (175°C). Lightly grease a 9 x 5 inch loaf pan or 8 inch square pan, then line it with parchment paper, leaving an overhang on two sides for easy removal.
- Wash and dry the zucchini, trim the ends, and finely grate it on the small holes of a box grater or using a food processor. Spread the grated zucchini on paper towels or a clean kitchen towel and gently blot the top to remove excess moisture without squeezing it completely dry. Set aside.
- In a medium bowl, whisk together the flour, baking powder, baking soda, and fine sea salt until well combined and free of lumps. Set aside.
- In a large mixing bowl, whisk the eggs and granulated sugar until slightly thickened and paler. Whisk in the neutral oil, Greek yogurt or sour cream, milk, fresh lemon juice, lemon zest, vanilla extract, and almond extract if using, until the mixture is smooth and well combined.
- Add the dry ingredients to the wet ingredients in two additions, gently stirring with a spatula after each addition just until no dry streaks of flour remain. Do not overmix.
- Fold in the prepared grated zucchini and mini white chocolate chips if using, just until evenly distributed. The batter will be thick but spreadable and speckled with green zucchini flecks.
- Scrape the batter into the prepared pan and smooth the top with a spatula. Tap the pan lightly on the counter to release any large air bubbles.
- Bake in the preheated oven for 40 to 50 minutes, or until the top is golden and a toothpick inserted into the center comes out with a few moist crumbs but no wet batter.
- Place the pan on a cooling rack and let the cake cool in the pan for 10 to 15 minutes. Use the parchment overhang to lift the cake out of the pan and place it directly on the rack. Let it cool until just slightly warm before glazing.
- While the cake is still slightly warm, prepare the sweet lemon glaze. In a small bowl, whisk together the powdered sugar, 2 tablespoons of fresh lemon juice, and the milk or cream until smooth. Add additional lemon juice a teaspoon at a time until the glaze is thick but pourable, then stir in lemon zest if using.
- Place a sheet of parchment or a tray under the cooling rack to catch drips. Slowly pour the sweet lemon glaze over the top of the warm cake, allowing it to drip down the sides. Let the glaze set for 20 to 30 minutes before slicing with a sharp serrated knife and serving.
