Zucchini Coffee Cake Recipe tastes like a super moist cinnamon crumb cake with tiny green flecks that stay tender and sweet, not veggie-ish at all. It works perfectly for busy families, brunch lovers, and anyone who wants a cozy treat in about 1 hour from start to finish. I baked a version of this on a Tuesday once and my neighbors still talk about it like it was a national holiday.
Why Choose This Zucchini Coffee Cake Recipe
This zucchini coffee cake recipe gives you bakery-style flavor with simple pantry ingredients. The zucchini keeps the crumb soft and moist, while the cinnamon streusel on top adds crunch and sweetness.
You mix everything in basic bowls, no mixer required, so cleanup stays easy. The recipe also uses melted butter and oil, which keeps the texture tender and forgiving, even if you slightly overbake it.

Ingredients You’ll Need
Dry ingredients
- 2 cups all-purpose flour
- Use a reliable brand like King Arthur or Gold Medal for consistent texture.
- 1 cup granulated sugar
- 1 teaspoon baking powder
- 1 teaspoon baking soda
- 1 teaspoon ground cinnamon
- ½ teaspoon fine sea salt
- ¼ teaspoon ground nutmeg (optional, but adds cozy flavor)
Wet ingredients
- 2 large eggs, room temperature
- ½ cup neutral oil (canola, vegetable, or light olive oil)
- ¼ cup unsalted butter, melted and slightly cooled
- 1 teaspoon vanilla extract
- 1 cup packed grated zucchini, moisture squeezed out
- Use small to medium zucchini for best flavor and fewer seeds.
- Do not peel; the green flecks look pretty and stay tender.
Streusel topping
- ¾ cup all-purpose flour
- ½ cup light brown sugar, packed
- 1 teaspoon ground cinnamon
- ¼ teaspoon fine sea salt
- 6 tablespoons cold unsalted butter, cut into small cubes
- If you only have salted butter, skip the added salt in the streusel.
Optional mix-ins
- ½ cup chopped walnuts or pecans
- ½ cup mini chocolate chips
- ¼ teaspoon ground cardamom for a bakery-style twist
Pantry shortcuts & substitutions
- Use pre-shredded zucchini from the store if you find it, but pat it very dry.
- Swap half the all-purpose flour with white whole wheat flour for a slightly heartier crumb.
- Replace some of the oil with applesauce if you want a lighter texture, though the cake may rise a bit less.
- Use coconut sugar instead of brown sugar in the streusel if you like a deeper caramel note.
Equipment list
- 8×8 inch or 9×9 inch square baking pan
- Parchment paper or nonstick spray
- Two medium mixing bowls
- Whisk and rubber spatula
- Box grater or food processor with grating disc for zucchini
- Measuring cups and spoons
- Knife and cutting board if you add nuts
Tips & Tricks
- Squeeze the zucchini very well; wrap it in a clean kitchen towel or paper towels and twist until it stops dripping.
- Pack the grated zucchini into the measuring cup after you squeeze it, not before.
- Line the pan with parchment and leave a little overhang so you lift the whole cake out easily.
- Mix the streusel until it forms clumpy, pea-sized bits; do not blend it into a paste.
- Stir the batter gently once you add the flour so you avoid tough, dense cake.
- Check doneness early at around 30 minutes, since every oven runs a little different.
- Let the cake cool at least 20 minutes before slicing so it holds its shape.
- Add nuts only to half the pan if you have mixed preferences; sprinkle them on one side of the streusel.
How to Make Zucchini Coffee Cake Recipe
Step 1: Prep the pan and oven
Preheat your oven to 350°F (175°C). Grease an 8×8 or 9×9 inch baking pan and line it with parchment, then lightly grease the parchment too. Set the pan aside while you mix the batter and topping.
Step 2: Grate and squeeze the zucchini
Wash and dry the zucchini. Grate it on the medium holes of a box grater. Wrap the grated zucchini in a clean kitchen towel or several layers of paper towel and squeeze hard until you remove as much liquid as possible, then measure 1 packed cup.
Step 3: Mix the streusel topping
In a medium bowl, combine ¾ cup flour, ½ cup brown sugar, 1 teaspoon cinnamon, and ¼ teaspoon salt. Add the cold butter cubes. Use your fingers or a pastry cutter and work the mixture until it forms clumps and crumbly bits, then place the bowl in the fridge while you mix the batter.
Step 4: Combine the dry ingredients
In another medium bowl, whisk together 2 cups flour, 1 cup sugar, baking powder, baking soda, 1 teaspoon cinnamon, ½ teaspoon salt, and nutmeg if you use it. Break up any sugar lumps with the whisk. Set the bowl aside.
Step 5: Mix the wet ingredients
In a large bowl, whisk the eggs until smooth. Add the oil, melted butter, and vanilla, then whisk until the mixture looks glossy and combined. Stir in the squeezed, measured zucchini and mix until it distributes evenly.
Step 6: Bring the batter together
Add the dry ingredients to the wet ingredients in two additions. Gently fold with a spatula until no dry streaks of flour remain. If you use nuts or chocolate chips, fold them in now, and stop mixing as soon as everything looks combined.
Step 7: Fill the pan and add streusel
Spread the batter evenly into the prepared pan and smooth the top. Take the chilled streusel from the fridge and break up any large chunks with your fingers. Sprinkle the streusel evenly over the batter, covering every corner for maximum crunchy topping.
Step 8: Bake
Place the pan on the middle rack of the oven. Bake for 30 to 40 minutes, depending on your pan size and oven. The cake finishes baking when a toothpick inserted in the center comes out with a few moist crumbs but no wet batter.
Step 9: Cool and slice
Set the pan on a wire rack and let the zucchini coffee cake cool at least 20 to 30 minutes. Use the parchment overhang to lift the cake out if you lined the pan that way. Slice into squares and serve warm or at room temperature.
What to Serve with it?
This zucchini coffee cake recipe pairs beautifully with hot coffee, cold brew, or a simple cup of black or herbal tea. Kids usually love it with a glass of cold milk or chocolate milk. You can also serve it on a brunch table with scrambled eggs, fresh fruit salad, and yogurt parfaits for a balanced spread. Add a spoonful of vanilla yogurt or a dollop of lightly sweetened whipped cream on top when you want it to feel like dessert.
Storage Options

Zucchini Coffee Cake Recipe
Ingredients
Method
- Preheat the oven to 350°F (175°C). Grease and flour a 9x13-inch baking pan or line it with parchment paper.
- Prepare the zucchini by shredding it on the small holes of a box grater. Place the shredded zucchini in a clean kitchen towel and squeeze out excess moisture. Measure 2 cups after squeezing and set aside.
- In a large bowl, whisk together the flour, granulated sugar, brown sugar, baking powder, baking soda, salt, cinnamon, and nutmeg until well combined.
- In a separate medium bowl, whisk the eggs, vegetable oil, yogurt or sour cream, and vanilla extract until smooth.
- Pour the wet ingredients into the dry ingredients and stir gently just until mostly combined. Fold in the prepared shredded zucchini, mixing only until no dry streaks of flour remain. Do not overmix.
- Spread the batter evenly into the prepared baking pan, smoothing the top with a spatula.
- In a small bowl, combine the flour, brown sugar, cinnamon, and salt for the topping.
- Drizzle in the melted butter and stir with a fork until the mixture forms moist clumps and crumbs.
- Sprinkle the crumb mixture evenly over the batter in the pan.
- Bake for 35–45 minutes, or until the top is golden and a toothpick inserted into the center comes out clean or with a few moist crumbs.
- Remove from the oven and let the coffee cake cool in the pan on a wire rack for at least 20–30 minutes.
- In a small bowl, whisk together the powdered sugar, 1 tablespoon of milk or cream, and vanilla. Add more milk a few drops at a time until the glaze is pourable but still thick.
- Drizzle the glaze over the cooled or slightly warm coffee cake. Allow a few minutes for the glaze to set before slicing.
- Slice the zucchini coffee cake into squares and serve warm or at room temperature. Store leftovers covered at room temperature for up to 2 days or refrigerated for up to 5 days.
