Ingredients
- 2 cups (240g) all-purpose flour
- 1 ½ teaspoons baking powder
- ½ teaspoon baking soda
- ½ teaspoon salt
- 1 tablespoon poppy seeds
- 1 cup (200g) granulated sugar
- ½ cup (100g) packed light brown sugar
- ¾ cup (180ml) vegetable oil or melted coconut oil
- 3 large eggs, at room temperature
- 1 teaspoon vanilla extract
- Zest of 2 medium lemons (about 2 tablespoons)
- ¼ cup (60ml) freshly squeezed lemon juice
- 2 cups (about 2 medium) grated zucchini, squeezed dry
- Optional: ½ cup chopped walnuts or pecans
Instructions
- Preheat your oven to 350°F (175°C). Grease and flour a 9×5-inch loaf pan or line it with parchment paper for easy removal.
- In a medium bowl, whisk together the flour, baking powder, baking soda, salt, and poppy seeds until evenly combined.
- In a large bowl, beat the granulated sugar, brown sugar, and oil together until smooth and well combined. Add the eggs one at a time, beating well after each addition.
- Mix in the vanilla extract, lemon zest, and lemon juice until fully incorporated.
- Fold the dry ingredients into the wet ingredients gently, just until no streaks of flour remain. Avoid overmixing to keep the cake tender.
- Fold in the grated zucchini and nuts if using, distributing evenly throughout the batter.
- Pour the batter into the prepared pan, smoothing the top with a spatula.
- Bake for 50-60 minutes, or until a toothpick inserted into the center comes out clean or with just a few moist crumbs attached.
- Allow the cake to cool in the pan for 15 minutes, then transfer to a wire rack to cool completely before slicing.
Tips
- Grating Zucchini: Use a medium grate and squeeze the excess moisture out with a clean kitchen towel or paper towels to avoid a soggy cake.
- Flour Substitutions: For a lighter texture, you can substitute half the all-purpose flour with whole wheat pastry flour, but expect a denser crumb.
- Lemon Flavor Boost: Add a teaspoon of lemon extract for a more intense lemon flavor if desired.
- Storage: Store the cake in an airtight container at room temperature for up to 3 days or refrigerate for up to 7 days to maintain freshness.
Serving Suggestions
This zucchini cake is delicious served plain or with a light dusting of powdered sugar. For a more decadent option, top slices with a lemon glaze made from powdered sugar and fresh lemon juice or a dollop of whipped cream. It pairs beautifully with a cup of tea or coffee for breakfast, brunch, or afternoon snack.
Variations
- Gluten-Free: Substitute the all-purpose flour with a 1:1 gluten-free baking flour blend. Add an extra ¼ teaspoon xanthan gum if your blend does not contain it.
- Dairy-Free/Vegan: Use a flax egg (1 tablespoon ground flaxseed mixed with 3 tablespoons water, set for 5 minutes) in place of eggs and swap oil for melted coconut oil. Use a plant-based yogurt or applesauce (¼ cup) to replace some moisture if needed.
- Orange Poppy Seed: Replace the lemon zest and juice with orange zest and juice for a sweeter, less tart cake.
- Spiced Version: Add 1 teaspoon ground cinnamon and ¼ teaspoon ground nutmeg to the dry ingredients for a warm spice note.
Storage and Reheating
Store the zucchini cake in an airtight container at room temperature for up to 3 days. For longer storage, refrigerate it for up to 7 days. Before serving, you can warm individual slices in the microwave for 10-15 seconds to bring back moisture and softness. If freezing, wrap the cooled cake tightly in plastic wrap and then aluminum foil; freeze for up to 3 months. Thaw overnight in the refrigerator before reheating.
Frequently Asked Questions
Can I use frozen zucchini in this cake?
Yes, but make sure to thaw and thoroughly drain or squeeze out all excess moisture from the frozen zucchini before using. Excess water can make the cake soggy and affect baking time.
Why does the cake sometimes turn out dense?
Overmixing the batter or adding too much zucchini moisture can cause a dense cake. Be sure to mix just until combined and dry the zucchini well. Also, measure flour accurately by spooning it into the cup and leveling off.
Can I make muffins instead of a loaf?
Absolutely! Scoop the batter into a lined or greased muffin tin and bake at 350°F (175°C) for about 20-25 minutes or until a toothpick comes out clean. Adjust baking time accordingly.
How do I know when the cake is done?
Insert a toothpick in the center of the cake. If it comes out clean or with a few moist crumbs (not wet batter), the cake is done. If unsure, check every 5 minutes after 50 minutes of baking.
Can I omit the nuts?
Yes, the nuts are optional and can be left out if you prefer a nut-free cake or want a smoother texture. You can also substitute with seeds like sunflower or pumpkin seeds for added crunch.
What is the best way to zest lemons?
Use a microplane or fine grater to zest only the yellow part of the lemon peel, avoiding the white pith underneath, which is bitter. Freshly grated zest provides the most aromatic lemon flavor.
Is this cake healthy because it has zucchini?
While zucchini adds moisture and some nutrients like vitamin C and fiber, this cake still contains sugar and oil, so it should be enjoyed as an occasional treat rather than a health food.
With its moist crumb, bright citrus flavor, and subtle crunch from poppy seeds, this lemon poppy seed zucchini cake is a versatile recipe that fits many occasions. Whether you’re looking for a fresh spring dessert or a comforting snack, this cake delivers balanced flavors and delightful texture every time.
