Ingredients You’ll Need

Dry ingredients

2 cups all-purpose flour (spooned and leveled for accuracy)
1 teaspoon baking powder
1 teaspoon baking soda
1 teaspoon ground cinnamon
1/2 teaspoon fine sea salt
1/4 teaspoon ground nutmeg (optional, but adds cozy flavor)

Wet ingredients

2 large eggs, room temperature
3/4 cup granulated sugar
1/2 cup light brown sugar, packed
1/2 cup neutral oil (canola, vegetable, or light olive oil)
1/2 cup plain Greek yogurt or sour cream
2 teaspoons pure vanilla extract

Add-ins

1 1/2 cups finely grated zucchini, lightly packed
- Use small or medium zucchini for the best texture.
- Do not peel; the green flecks look pretty in the cake.
1 1/2 cups fresh blueberries
- You can use frozen blueberries; keep them frozen and toss in flour so they do not bleed too much.
1 tablespoon all-purpose flour (to toss with blueberries so they stay suspended in the batter)

Optional lemon glaze

1 cup powdered sugar, sifted
2–3 tablespoons fresh lemon juice
1/2 teaspoon lemon zest
Pinch of salt

Equipment

9×13 inch baking pan or two 8 inch round cake pans
Parchment paper (helps with easy removal)
Box grater or food processor with grating disc for zucchini
Large mixing bowl and medium mixing bowl
Whisk and rubber spatula
Measuring cups and spoons
Cooling rack

Tips & Tricks

Squeeze the grated zucchini gently in a clean kitchen towel to remove excess moisture, but keep it slightly damp so the cake stays tender.
Toss blueberries with 1 tablespoon flour so they stay evenly distributed and do not all sink to the bottom.
Use room temperature eggs and yogurt so the batter mixes smoothly and bakes evenly.
Line the pan with parchment and lightly grease it so the cake releases easily and stays intact.
Mix the batter just until the flour disappears; overmixing can make the cake tough.
Check the cake a few minutes early since every oven runs a little different; a toothpick should come out with a few moist crumbs, not wet batter.
Cool the cake completely before glazing so the glaze sets instead of sliding off.
Swap Greek yogurt with sour cream if that sits in your fridge; both give a tender crumb and slight tang.
Use frozen blueberries straight from the freezer; do not thaw or they bleed too much into the batter.
Add a pinch of lemon zest to the batter if you love a bright citrus note with blueberries.

How to Make Blueberry Zucchini Cake Recipe

Step 1: Prep the pan and oven

Preheat your oven to 350°F (175°C). Grease a 9×13 inch pan and line the bottom with parchment paper, then lightly grease the parchment as well. Set the pan aside while you mix the batter.

Step 2: Prep the zucchini

Wash and dry the zucchini. Grate it on the small holes of a box grater or use a food processor with a grating disc. Place the grated zucchini in a clean kitchen towel and gently squeeze out excess liquid until it feels damp but not dripping, then set it aside.

Step 3: Mix the dry ingredients

In a medium bowl, whisk together the flour, baking powder, baking soda, cinnamon, salt, and nutmeg. Break up any lumps so the mixture looks even. Set this bowl aside.

Step 4: Mix the wet ingredients

In a large bowl, whisk the eggs, granulated sugar, and brown sugar until the mixture looks slightly thick and lighter in color. Add the oil, Greek yogurt or sour cream, and vanilla extract, then whisk until smooth. Scrape down the sides of the bowl with a spatula so everything mixes evenly.

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 disappears. Stop mixing as soon as you see a smooth batter so you keep the cake tender.

Step 6: Fold in zucchini and blueberries

Fold the grated zucchini into the batter until it distributes evenly. In a small bowl, toss the blueberries with 1 tablespoon flour, then shake off any extra flour. Gently fold the blueberries into the batter so you do not crush them.

Step 7: Fill the pan and bake

Pour the batter into the prepared pan and spread it into an even layer with a spatula. Tap the pan lightly on the counter to pop any large air bubbles. Bake for 30 to 38 minutes, until a toothpick inserted in the center comes out with a few moist crumbs.

Step 8: Cool the cake

Place the pan on a cooling rack. Let the cake cool in the pan for at least 20 to 30 minutes. You can serve it slightly warm from the pan or lift it out with the parchment once it cools more.

Step 9: Mix the lemon glaze

While the cake cools, add powdered sugar, lemon juice, lemon zest, and a pinch of salt to a small bowl. Whisk until smooth and pourable; add a few drops more lemon juice if it feels too thick, or a spoon of powdered sugar if it feels too thin. The glaze should slowly run off the spoon in a thick ribbon.

Step 10: Glaze and slice

When the cake cools to just slightly warm or room temperature, drizzle the lemon glaze over the top. Let the glaze set for about 10 to 15 minutes. Slice into squares and serve.

What to Serve with Blueberry Zucchini Cake Recipe

This Blueberry Zucchini Cake Recipe pairs beautifully with a cold glass of milk or a mug of hot coffee. Kids usually love it with a cup of cocoa or vanilla almond milk. You can add a scoop of vanilla ice cream or a spoonful of whipped cream on top for a more dessert-style plate. Fresh berries on the side make the slices look extra pretty and add a refreshing touch.

Storage Options

Store leftover cake tightly covered at room temperature for up to 2 days if your kitchen stays cool.
Keep the cake in an airtight container in the fridge for up to 5 days; let slices sit at room temperature for 15 minutes before serving so the texture softens.
Freeze individual slices wrapped in plastic, then place them in a freezer bag for up to 2 months.
Reheat slices in the microwave for 10 to 15 seconds or in a low oven at 300°F for about 5 to 8 minutes until just warm.
