There’s something incredibly comforting about a warm slice of coffee cake, especially when it boasts the subtle sweetness and moisture that zucchini brings.

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 this moist and delicious cake is preparing the zucchini. You’ll want to shred your zucchini. You can do this using the large holes of a box grater or a food processor with a grating attachment. Once shredded, it’s crucial to remove as much excess moisture as possible. This might sound counterintuitive since we want the moisture for the cake, but excess water can lead to a gummy texture. Place the shredded zucchini in a clean kitchen towel or cheesecloth and squeeze firmly to wring out the liquid. Discard the liquid. This step is key to achieving the perfect cake texture. Don’t worry if you don’t get every single drop; a little residual moisture is fine and will contribute to the cake’s tenderness.
Making the Coffee Cake Batter
Dry Ingredients:
In a medium-sized bowl, whisk together the 1 ½ cups of all-purpose flour, 2 teaspoons of baking powder, 1 teaspoon of cinnamon, and ½ teaspoon of salt. Whisking these ingredients together ensures they are evenly distributed, which will lead to a more uniform rise and flavor in your cake.
Wet Ingredients:
In a separate larger bowl, cream together the ¾ cup of granulated sugar and the ¼ cup of vegetable oil. Mix until well combined. Then, beat in the 1 large egg until fully incorporated. Gradually add the ½ cup of milk, mixing until the batter is smooth.
Combining the Wet and Dry:
Now, it’s time to combine the wet and dry ingredients. Gradually add the dry ingredient mixture to the wet ingredients, mixing until just combined. Be careful not to overmix the batter at this stage, as overmixing can develop the gluten in the flour too much, resulting in a tougher cake. A few lumps are perfectly acceptable.
Adding the Zucchini:
Gently fold the 2 cups of squeezed shredded zucchini into the batter. Ensure the zucchini is evenly distributed throughout the mixture. The batter will be thick, and that’s exactly what you want.
Creating the Streusel Topping
In a small bowl, combine the ½ cup of packed brown sugar, 1 tablespoon of all-purpose flour, and 1 teaspoon of cinnamon. Stir these ingredients together until they are well combined and resemble coarse crumbs. Drizzle the 2 tablespoons of melted butter over the brown sugar mixture. Use a fork or your fingers to mix the butter into the dry ingredients until the mixture forms small, clumpy bits. This is your delicious streusel topping, which will add a delightful crunchy and sweet contrast to the soft cake.
Baking the Zucchini Coffee Cake
Preheat your oven to 350 degrees Fahrenheit (175 degrees Celsius). Grease and flour an 8×8 inch baking pan or a similarly sized round cake pan. Pour the prepared batter into the greased and floured pan, spreading it evenly. Sprinkle the prepared streusel topping generously and evenly over the entire surface of the batter.
Bake for 30 to 40 minutes, or until a wooden skewer or toothpick inserted into the center of the cake comes out clean. The top should be golden brown and the streusel topping should be delightfully crisp. Once baked, remove the cake from the oven and let it cool in the pan on a wire rack for at least 15-20 minutes before attempting to slice and serve. This cooling period is important for the cake to set properly, making it easier to cut and preventing it from falling apart. For an extra special touch, you can dust the cooled cake with a little powdered sugar or drizzle it with a simple glaze made from powdered sugar and milk. Enjoy your homemade Zucchini Coffee Cake!

Conclusion:
So there you have it – a delightful Zucchini Coffee Cake recipe that’s truly a winner! This cake is fantastic because it strikes the perfect balance between moist, tender crumb and a satisfyingly crunchy streusel topping. The hidden zucchini not only adds incredible moisture but also makes this a wonderfully guilt-free indulgence, allowing you to sneak in some veggies without anyone being the wiser. It’s the ideal treat for a leisurely brunch, a cozy afternoon pick-me-up with your favorite coffee, or even a light dessert after dinner. I’ve found it’s best served slightly warm, allowing the buttery crumble to really shine, but it’s equally delicious at room temperature. Don’t be afraid to get creative with variations! Adding a handful of chopped pecans or walnuts to the streusel, or a sprinkle of cinnamon to the cake batter itself, can elevate it even further. I truly encourage you to give this Zucchini Coffee Cake a try – you won’t be disappointed!
