What Ingredients You Will Need

This recipe uses simple, wholesome ingredients to deliver bold flavor and satisfying texture without the fuss. Most are pantry staples, with fresh zucchini and blueberries adding a seasonal flair.

• All-purpose flour – 2 cups (240g), for the bread base. You can swap half for whole wheat for a nuttier flavor.
• Baking powder – 1 teaspoon, to help the bread rise.
• Baking soda – ½ teaspoon, balances acidity and adds tenderness.
• Salt – ½ teaspoon, enhances all the flavors.
• Ground cinnamon – 1 teaspoon, adds warm spice.
• Granulated sugar – ¾ cup (150g), for sweetness.
• Brown sugar – ½ cup (100g), packed, used both in the batter and streusel topping for depth.
• Vegetable oil – ⅓ cup (80ml), keeps the bread moist without heaviness. I prefer a neutral oil like canola or avocado oil.
• Large eggs – 2, at room temperature for better mixing.
• Vanilla extract – 1 teaspoon, for aroma and flavor lift.
• Zucchini – 1 ½ cups shredded (about 1 medium zucchini). Make sure to squeeze out excess moisture to avoid sogginess.
• Fresh blueberries – 1 cup (150g). If out of season, frozen works well—just don’t thaw before folding in.

For the Brown Sugar Streusel Topping:

• Brown sugar – ⅓ cup (67g), packed, for that caramelized crunch.
• All-purpose flour – ¼ cup (30g), to bind the topping.
• Ground cinnamon – ½ teaspoon, adds warmth.
• Cold unsalted butter – 3 tablespoons (42g), cut into small cubes. I recommend using a good quality butter like Kerrygold for richer flavor.

Feel free to swap all-purpose flour with almond flour for a gluten-free option, though the texture will be a bit different. For dairy-free needs, coconut oil can replace butter in the streusel, but keep it chilled so it clumps nicely.

Equipment Needed

• Loaf pan (9×5 inches / 23×13 cm) – standard size works best for even baking.
• Mixing bowls – one large for the batter, one small for the streusel topping.
• Box grater or food processor – to shred the zucchini quickly (I like using a box grater because it’s easy to clean and control shredding thickness).
• Measuring cups and spoons – for precise ingredient amounts.
• Whisk and rubber spatula – whisk for dry ingredients and eggs, spatula for folding in zucchini and blueberries gently.
• Cooling rack – to let the bread cool evenly and avoid soggy bottoms.

If you don’t have a loaf pan, a muffin tin can be a fun alternative—just adjust the baking time accordingly. For grating zucchini, I’ve found that a food processor with a shredding disc speeds things up but sometimes makes the zucchini wetter, so be sure to press out the moisture.

Preparation Method

1. Preheat your oven to 350°F (175°C) and grease your loaf pan with butter or non-stick spray. This helps the bread release easily once baked. (5 minutes)
2. Prepare the zucchini: Using a box grater, shred about 1 ½ cups (about 1 medium zucchini). Place shredded zucchini in a clean kitchen towel or paper towels and squeeze out as much moisture as possible to prevent a soggy bread. (10 minutes)
3. Mix the dry ingredients: In a large bowl, whisk together 2 cups (240g) all-purpose flour, 1 teaspoon baking powder, ½ teaspoon baking soda, ½ teaspoon salt, and 1 teaspoon ground cinnamon. This ensures even distribution of leaveners and spices. (3 minutes)
4. Combine the sugars and wet ingredients: In a separate bowl, whisk ¾ cup (150g) granulated sugar, ½ cup (100g) brown sugar, ⅓ cup (80ml) vegetable oil, 2 large eggs, and 1 teaspoon vanilla extract until smooth and slightly frothy. (5 minutes)
5. Combine wet and dry mixtures: Pour the wet ingredients into the dry ingredients bowl. Stir gently with a rubber spatula until just combined—avoid overmixing to keep the bread tender. (2-3 minutes)
6. Fold in shredded zucchini and fresh blueberries: Carefully fold in the zucchini and 1 cup (150g) fresh blueberries to preserve their shape and prevent the batter from turning blue. (2 minutes)
7. Prepare the brown sugar streusel topping: In a small bowl, mix ⅓ cup (67g) brown sugar, ¼ cup (30g) flour, and ½ teaspoon cinnamon. Cut in 3 tablespoons (42g) cold unsalted butter using a pastry cutter or fingertips until the mixture resembles coarse crumbs. (5 minutes)
8. Transfer the batter to the prepared loaf pan: Spread evenly, then sprinkle the streusel topping generously over the batter. (2 minutes)
9. Bake: Place in the oven and bake for 55-65 minutes, or until a toothpick inserted in the center comes out clean or with just a few moist crumbs. If the streusel browns too quickly, tent the bread loosely with foil after 40 minutes. (55-65 minutes)
10. Cool: Remove from oven, let the bread cool in the pan for 15 minutes, then transfer to a cooling rack to cool completely. This prevents the bottom from getting soggy and helps the bread set. (30 minutes)

Pro tip: If your batter seems too thick, that’s normal—zucchini adds moisture but also bulk. Also, don’t skip squeezing out the zucchini; I learned that the hard way when my first loaf was too wet and dense. Once cooled, slicing with a serrated knife helps keep the loaf intact, especially with the crumbly streusel topping.

Cooking Tips & Techniques

When making this Moist Blueberry Zucchini Bread, a few insider tips can make all the difference:

• Don’t overmix the batter. Stir until just combined. Overmixing activates gluten and can lead to a tougher bread.
• Squeeze zucchini well. Excess moisture is the enemy of a tender crumb. Wrap shredded zucchini in a towel and squeeze until barely damp.
• Fresh vs. frozen blueberries. If using frozen, add them directly to the batter without thawing to prevent color bleed.
• Cold butter for streusel. Keep butter chilled and cut it into flour and sugar quickly for that perfect crumbly topping.
• Baking time varies. Ovens differ, so start checking at 50 minutes. A toothpick test is your best friend.
• Multitasking: Prepare the streusel while the batter rests to save time and keep things moving smoothly.

I once forgot to add baking soda and ended up with a very flat loaf—lesson learned! Also, using a serrated knife to slice the bread preserves the crumb and topping much better than a straight-edge blade.

Variations & Adaptations

This recipe is pretty flexible, so let me share a few ways to make it your own:

• Gluten-Free Option: Use a 1:1 gluten-free baking flour blend instead of all-purpose flour. The bread will be just as moist but with a slightly different texture.
• Vegan Adaptation: Swap eggs for flax eggs (2 tbsp ground flaxseed + 6 tbsp water, chilled for 10 minutes) and use coconut oil in place of vegetable oil and vegan butter for the streusel.
• Seasonal Twist: In summer, swap blueberries for fresh raspberries or chopped peaches for a juicy change of pace.
• Added Nuts: Toss in ½ cup chopped walnuts or pecans for crunch and earthiness.
• Spice It Up: Add ¼ teaspoon nutmeg or a pinch of ground ginger for a warmer, spicier flavor profile.

My personal favorite is adding a handful of toasted coconut flakes on top of the streusel for a tropical vibe. It sounds fancy but is honestly just a sprinkle away from simple.

Serving & Storage Suggestions

This Moist Blueberry Zucchini Bread tastes best at room temperature or slightly warmed. I like slicing it thick with a smear of butter or cream cheese, but it’s also great plain. For a cozy brunch, pair it with a hot cup of cinnamon-spiced coffee or a fresh herbal tea. It also pairs nicely with a light fruit salad or yogurt on the side for a balanced breakfast.

Store leftover bread wrapped tightly in plastic wrap or in an airtight container at room temperature for up to 3 days. It keeps well in the fridge for about a week but tends to dry out a bit, so warming slices gently in the microwave (15-20 seconds) helps restore softness.

If you want to keep it longer, slice and freeze the bread in zip-top bags for up to 3 months. Toast or microwave frozen slices straight from the freezer for a quick treat. The flavors actually deepen after a day or two, so making it ahead can be a smart move for gatherings.
