Key Ingredients for Zucchini Coffee Cake
For the Cake:
- 2 cups all-purpose flour
- 1 cup granulated sugar
- ½ cup brown sugar, packed
- ½ cup vegetable oil
- 2 large eggs
- 1 cup buttermilk
- 1½ cups fresh zucchini, grated
- 1 teaspoon vanilla extract
- 1 teaspoon baking soda
- 1 teaspoon ground cinnamon
- ½ teaspoon salt

Step-by-Step Instructions
Prepare Your Kitchen Preheat your oven to 350°F (175°C). Grease a 9×13 inch baking pan with butter or cooking spray. Line with parchment paper for easy removal. This preparation ensures your cake releases perfectly every time.
Grate the Zucchini Wash and dry 2 medium zucchini. Using a box grater, grate the zucchini using the large holes. You’ll need about 1½ cups of grated zucchini. No need to peel the zucchini – the skin adds nutrients and won’t affect the taste.
Make the Streusel Topping In a medium bowl, combine flour, brown sugar, cinnamon, and salt. Add cold cubed butter and use your fingers or a pastry cutter to work it into the dry ingredients until the mixture resembles coarse crumbs. Set aside while you prepare the cake batter.
Mix the Wet Ingredients In a large mixing bowl, whisk together the eggs, vegetable oil, buttermilk, and vanilla extract until well combined. The mixture should be smooth and uniform in color.
Combine Dry Ingredients In a separate bowl, whisk together flour, granulated sugar, brown sugar, baking soda, cinnamon, and salt. Make sure there are no lumps and all ingredients are evenly distributed.
Create the Batter Pour the wet ingredients into the dry ingredients. Gently fold together using a wooden spoon or rubber spatula until just combined. Don’t overmix – a few lumps are perfectly fine and will ensure a tender cake.
Add the Zucchini Fold the grated zucchini into the batter until evenly distributed. The zucchini will release some moisture, which is exactly what creates the cake’s signature moistness.
Assemble and Bake Pour the batter into your prepared baking pan and spread evenly. Sprinkle the streusel topping evenly over the entire surface. Bake for 45-50 minutes, or until a toothpick inserted in the center comes out with just a few moist crumbs.
Cool and Serve Allow the cake to cool in the pan for 15 minutes before cutting. This cooling time helps the cake set properly and makes slicing much easier.
What to Serve Zucchini Coffee Cake With
This versatile cake pairs beautifully with various beverages and accompaniments:
Hot Beverages: Freshly brewed coffee, chai tea, or hot chocolate complement the warm spices perfectly.
Cold Drinks: Iced coffee, cold milk, or even a refreshing glass of lemonade balance the cake’s richness.
Breakfast Additions: Serve alongside fresh berries, Greek yogurt, or a dollop of whipped cream for a complete breakfast spread.
Brunch Spread: Include it in a brunch buffet with scrambled eggs, bacon, and fresh fruit for a memorable morning meal.

Top Tips for Perfecting Zucchini Coffee Cake
Don’t Squeeze the Zucchini Unlike other recipes, don’t drain or squeeze the grated zucchini. The natural moisture is essential for creating the cake’s signature texture. The excess liquid gets absorbed during baking, creating incredible moistness.
Room Temperature Ingredients Use eggs and buttermilk at room temperature for better mixing and a more tender crumb. Take them out of the refrigerator 30 minutes before baking.
Proper Mixing Technique Mix the batter just until ingredients are combined. Overmixing develops the gluten too much, resulting in a tough, dense cake instead of the desired tender texture.
Streusel Success Keep the butter cold when making streusel. Cold butter creates better texture and prevents the topping from melting into the cake during baking.
Substitution Options Yellow squash works as a 1:1 substitute for zucchini. You can also replace half the all-purpose flour with whole wheat flour for added nutrition without sacrificing taste.
Storage Secret Store the cooled cake covered at room temperature. The zucchini actually helps the cake stay moist for several days, making it perfect for meal prep or make-ahead entertaining.
Storing and Reheating Tips
Room Temperature Storage Cover the cake tightly with plastic wrap or store in an airtight container for up to 4 days at room temperature. The zucchini’s natural moisture keeps it fresh longer than traditional coffee cakes.
Refrigerator Storage For longer storage, refrigerate for up to 1 week. Bring to room temperature before serving, or warm individual slices in the microwave for 15-20 seconds.
Freezing Instructions Wrap individual slices in plastic wrap, then place in freezer bags for up to 3 months. Thaw overnight in the refrigerator or at room temperature for 2 hours.
Reheating Methods For best results, reheat in a 300°F oven for 5-10 minutes. This method maintains the streusel’s crunchiness better than microwave reheating.

Frequently Asked Questions
Can I use frozen zucchini for this coffee cake? Fresh zucchini works best for optimal texture and moisture. If using frozen, thaw completely and drain excess water before measuring. The cake may be slightly less moist but still delicious.
How do I know when the zucchini coffee cake is done? Insert a toothpick in the center – it should come out with a few moist crumbs but not wet batter. The edges will also start pulling slightly away from the pan sides.
Can I make this cake gluten-free? Yes! Substitute the all-purpose flour with a 1:1 gluten-free flour blend. The texture will be slightly different but still delicious. Make sure your blend contains xanthan gum.
What’s the best way to grate zucchini? Use the large holes of a box grater for the perfect texture. Food processors work too, but use the shredding disc and pulse briefly to avoid over-processing.
Can I reduce the sugar in this recipe? You can reduce the granulated sugar by up to ¼ cup, but this may affect the cake’s moisture and texture. The brown sugar helps create the tender crumb, so avoid reducing it.
Why is my streusel topping not crunchy? Make sure your butter is cold when making the streusel. If the topping seems to disappear into the cake, your butter may have been too soft or the oven temperature too low.
Can I add nuts or chocolate chips? Absolutely! Fold in ½ cup of chopped walnuts, pecans, or chocolate chips with the zucchini. This adds extra flavor and texture variation.
How can I make this cake more healthy? Replace half the all-purpose flour with whole wheat flour, use applesauce for half the oil, or add ground flaxseed for extra nutrition. Greek yogurt can substitute for some of the buttermilk too.
Additional Helpful Tips for Success
Seasonal Baking Variations During fall, add ½ teaspoon of nutmeg and a pinch of ground cloves to the batter for warm autumn flavors. In summer, fold in fresh blueberries or lemon zest for bright, seasonal taste.
Make-Ahead Magic This cake actually improves overnight as the flavors meld together. Bake it the evening before serving for the best taste and texture. Cover tightly and store at room temperature.
Gifting Ideas This coffee cake makes wonderful gifts for neighbors, teachers, or new parents. Bake in disposable aluminum pans for easy gifting, and include the recipe card attached with a ribbon.
Scaling the Recipe Double the recipe easily for large gatherings. Use two 9×13 pans or one large sheet pan. Increase baking time by 5-10 minutes and check for doneness with a toothpick.
Troubleshooting Common Issues If your cake sinks in the middle, you may have overmixed the batter or opened the oven door too early. If it’s too dense, check that your baking soda is fresh – it should foam when mixed with a little vinegar.
