Blueberry Zucchini Cake Recipe delivers a moist, tender crumb with pops of juicy blueberries and a bright lemon glaze. It suits anyone who loves an easy summer bake that feeds a crowd, and it takes about 1 hour 15 minutes start to finish. I baked a version for my neighbors last weekend and not a crumb survived.
Why Blueberry Zucchini Cake Recipe Is Worth It
Blueberry Zucchini Cake Recipe blends garden-fresh zucchini with sweet berries for a soft, plush cake that stays moist for days. The zucchini melts into the batter and adds structure, while blueberries bring pockets of jammy goodness. A quick lemon glaze ties it all together with a tangy finish.
You can mix it in one bowl, and it works in a loaf, a square pan, or as a layer cake. The batter stays sturdy enough for fresh or frozen blueberries, so you can bake it year-round. You also get bakery flavor without fancy equipment.
Ingredients You Need
Cake:
-
- All-purpose flour, 2 cups, spooned and leveled (I like King Arthur for consistent protein)
- Baking powder, 2 teaspoons
- Baking soda, 1/2 teaspoon
- Fine sea salt, 1/2 teaspoon
- Ground cinnamon, 1 teaspoon, optional but tasty with blueberries
- Granulated sugar, 3/4 cup
- Light brown sugar, 1/4 cup, packed
- Eggs, 2 large, room temp for best rise
- Neutral oil, 1/2 cup, such as avocado or canola; olive oil works for a fruitier note; melted butter works but firms up more
- Buttermilk, 1/2 cup; swap with 1/2 cup milk mixed with 2 teaspoons lemon juice or vinegar
- Sour cream or plain Greek yogurt, 1/3 cup, for extra tenderness
- Vanilla extract, 2 teaspoons
- Lemon zest, 1 tablespoon, for brightness
- Zucchini, 2 cups lightly packed, finely shredded and squeezed of excess moisture
- Blueberries, 1 1/2 cups; fresh or frozen; if frozen, do not thaw
- Optional add-in: 1 tablespoon cornstarch to toss with blueberries to reduce sinking
Lemon glaze:
-
- Powdered sugar, 1 to 1 1/4 cups, sifted for a smooth finish
- Fresh lemon juice, 2 to 3 tablespoons; bottled works in a pinch
- Lemon zest, 1/2 teaspoon
- Pinch of salt
- 1 to 2 teaspoons milk or cream to loosen if needed
Pantry shortcuts and swaps:
-
- Use a 1:1 gluten-free flour blend like Bob’s Red Mill if you bake gluten-free
- Use frozen blueberries straight from the freezer
- Use bottled lemon juice for glaze when citrus runs low
- Skip lemon and use vanilla glaze if citrus is not your thing
Equipment:
-
- 9 by 13 inch pan, or two 8 inch rounds, or a 10 cup bundt pan
- Parchment paper and nonstick baking spray
- Box grater or food processor with grating disc
- Large mixing bowl, whisk, rubber spatula
- Cooling rack and skewer for doneness check
Quick Tips & substitutions
- Squeeze shredded zucchini in a clean towel to remove excess moisture. Aim for damp, not dry.
- Dust blueberries with 1 tablespoon flour or cornstarch to help suspend them in the batter.
- Use room temperature eggs and dairy for a plush crumb and even mixing.
- Swap buttermilk with milk plus lemon juice or vinegar at a 1 cup to 1 tablespoon ratio.
- Bake in a metal pan for best rise; glass may need a few extra minutes.
- If berries sit on top, swirl a spoon through the top inch of batter to distribute.
- Stir the batter just until no dry streaks remain. Overmixing toughens the crumb.
- Glaze while the cake feels slightly warm so it sets with a thin, shiny coat.
How to Make Blueberry Zucchini Cake
Prep: 20 minutes
Cook: 50 to 55 minutes
Total: about 1 hour 15 minutes
- Heat the oven to 350°F. Line your pan with parchment and spray it well.
- Shred the zucchini on the fine holes of a box grater. Place it in a clean towel and squeeze out excess liquid until it feels damp.
- Whisk flour, baking powder, baking soda, salt, and cinnamon in a large bowl. Set it aside.
- In another bowl, whisk sugar, brown sugar, eggs, oil, buttermilk, sour cream, vanilla, and lemon zest until smooth.
- Add the wet mixture to the dry ingredients. Stir with a spatula until the batter looks smooth and no flour pockets remain.
- Toss blueberries with 1 tablespoon flour or cornstarch if you want extra insurance. Fold zucchini and blueberries into the batter gently.
- Spread the batter into the prepared pan. Smooth the top.
- Bake until a skewer comes out clean or with a few moist crumbs, about 50 to 55 minutes for a 9 by 13 pan, 28 to 32 minutes for two 8 inch rounds, or 55 to 60 minutes for a bundt.
- Cool the cake on a rack for 15 minutes. Run a knife around the edges, then lift out or invert if using a bundt.
- Whisk powdered sugar, lemon juice, zest, and a pinch of salt for the glaze. Adjust with a splash of milk to reach a thick drizzle.
- Spoon the glaze over the warm cake. Let it set for at least 20 minutes before slicing.
Simple Variations
- Swap blueberries with raspberries or blackberries. Mix berries if you want more color.
- Add 1/2 cup white chocolate chips for a creamy bite.
- Stir in 1/2 cup chopped toasted pecans or walnuts for crunch.
- Skip the glaze and frost with lemon cream cheese frosting for a richer finish.
- Add 1 tablespoon poppy seeds and 1 extra tablespoon lemon zest for a bakery spin.
Ways to Serve Blueberry Zucchini Cake
- Serve slightly warm with vanilla ice cream.
- Pair with lemony whipped cream and extra fresh berries.
- Pack chilled slices for picnics or lunch boxes.
- Bring to brunch with coffee or cold brew.
- Plate with a drizzle of honey and a pinch of flaky salt.
Storage
Store the cake covered at room temperature for 2 days. Move it to the fridge after that and keep it for up to 5 days. Freeze slices in a single layer, then wrap and keep them in a freezer bag for up to 2 months. Thaw on the counter and refresh with a light warm-up if you like a softer texture.
