Let’s get started with the ingredients you’ll need to create this delicious masterpiece.
Ingredients:
- 1 ½ cups (186g) all-purpose flour
- 2 teaspoons baking powder
- 1 teaspoon cinnamon
- ½ teaspoon salt
- ¾ cup (150g) granulated sugar
- ¼ cup (60ml) vegetable oil
- 1 large egg
- ½ cup (118ml) milk
- 2 cups (approx 206g) shredded zucchini ((approx 1 large or 2 small))
- ½ cup (100g) packed brown sugar
- 1 tablespoon (8g) all-purpose flour
- 1 teaspoon cinnamon
- 2 tablespoons (28g) butter, melted
Preparing the Zucchini
The first step in creating our Zucchini Coffee Cake is to prepare the zucchini. You’ll want to shred your zucchini using the large holes of a box grater. Once shredded, it’s crucial to get rid of as much excess moisture as possible. This step is key to ensuring your cake isn’t too wet and has the perfect texture. You can do this by placing the shredded zucchini in a fine-mesh sieve set over a bowl and gently pressing down on it with the back of a spoon to squeeze out the liquid. Alternatively, you can wrap the shredded zucchini in a clean kitchen towel or cheesecloth and wring it out thoroughly. This might seem like a small step, but it makes a significant difference in the final outcome of your cake. You should aim to get about 2 cups of well-drained shredded zucchini.
Mixing the Cake Batter
Now it’s time to bring the cake batter together. In a large mixing bowl, whisk together the 1 ½ cups of all-purpose flour, baking powder, 1 teaspoon of cinnamon, and salt. This ensures all the dry ingredients are evenly distributed, which is important for a consistent rise and texture in your cake. In a separate medium bowl, whisk together the ¾ cup of granulated sugar, vegetable oil, and the large egg until well combined. Then, gradually add the milk to this wet mixture, whisking until smooth. Now, pour the wet ingredients into the dry ingredients and mix until just combined. Be careful not to overmix the batter; a few small lumps are perfectly fine. Overmixing can develop the gluten in the flour, leading to a tougher cake. Finally, gently fold in the prepared, drained shredded zucchini until it’s evenly distributed throughout the batter.
Creating the Streusel Topping
No coffee cake is complete without a delicious streusel topping, and this one is a winner. In a small bowl, combine the ½ cup of packed brown sugar, 1 tablespoon of all-purpose flour, and 1 teaspoon of cinnamon. Whisk these ingredients together until they are well incorporated. Drizzle the 2 tablespoons of melted butter over the dry streusel ingredients. Using a fork or your fingertips, work the butter into the brown sugar and flour mixture until it forms coarse crumbs. You want a consistency that clumps together slightly when squeezed, but still has distinct crumbly pieces. This topping will add a wonderful crunchy texture and a burst of sweet cinnamon flavor to your cake.
Assembling and Baking
Preheat your oven to 350°F (175°C). Grease and flour an 8×8 inch baking pan or a 9-inch round cake pan. Pour the cake batter into the prepared pan and spread it evenly. Now, sprinkle the prepared streusel topping evenly over the batter, making sure to cover the entire surface. This delicious layer of cinnamon-sugar goodness is what makes this coffee cake so irresistible. Place the pan in the preheated oven and bake for approximately 30-40 minutes, or until a wooden skewer or toothpick inserted into the center of the cake comes out clean. The baking time can vary depending on your oven, so it’s always best to check for doneness a little before the recommended time.
Cooling and Serving
Once your Zucchini Coffee Cake is baked to perfection, remove it from the oven and let it cool in the pan on a wire rack for about 10-15 minutes. This allows the cake to set slightly before you attempt to remove it. After this initial cooling period, you can carefully invert the cake onto the wire rack to cool completely. It’s important to let it cool thoroughly before slicing, as a warm cake can be more delicate. Once cooled, slice it into squares or wedges and enjoy! This cake is absolutely divine on its own, but if you’re feeling extra decadent, a dusting of powdered sugar or a drizzle of cream cheese glaze would be absolutely heavenly. Savor this moist, flavorful, and secretly healthy treat!

Conclusion:
There you have it – a delicious and surprisingly simple Zucchini Coffee Cake Recipe that’s sure to become a favorite in your baking rotation! This recipe is fantastic because it uses everyday ingredients, incorporates the goodness of fresh zucchini for incredible moisture and a subtle earthy sweetness, and delivers a perfectly tender crumb topped with a delightful streusel.

I love serving this warm with a dollop of whipped cream or a scoop of vanilla ice cream, but it’s equally delightful on its own, perhaps with your morning coffee or afternoon tea. Don’t be afraid to get creative with variations! Consider adding a touch of cinnamon or nutmeg to the batter, or perhaps some chopped pecans or walnuts to the streusel topping for extra crunch and flavor. You could even swirl in some cream cheese for a decadent cheesecake-inspired twist. I truly encourage you to give this Zucchini Coffee Cake a try; you might just surprise yourself with how much you love it!
Frequently Asked Questions:
Can I make this Zucchini Coffee Cake ahead of time?
Absolutely! This Zucchini Coffee Cake stores beautifully. Once completely cooled, wrap it tightly in plastic wrap and then in foil. It will stay fresh at room temperature for 2-3 days, or you can refrigerate it for up to a week. Reheat individual slices gently in the oven or microwave if you prefer it warm.
What kind of zucchini works best?
Any type of zucchini will work well in this recipe. Ensure you shred it using the large holes of a box grater and then gently squeeze out any excess moisture before adding it to the batter. This step is crucial for preventing a soggy cake.
My streusel topping is too dry, what did I do wrong?
If your streusel is too dry, it usually means the butter wasn’t cold enough or there wasn’t enough butter. Make sure your butter is very cold and cut into small pieces before mixing with the dry ingredients. The goal is to achieve a crumbly texture that holds together when squeezed, not a paste or dry powder.
