How to Make Blueberry Zucchini Cake:
Quick Overview
This blueberry zucchini cake is surprisingly simple to make, requiring basic mixing techniques and common baking skills. The secret lies in properly preparing the zucchini and gently folding in the blueberries.
Prep Time: 15 minutes
Bake Time: 50-60 minutes
Total Time: 1 hour 15 minutes
Serves: 12 slices
Key Ingredients for Blueberry Zucchini Cake:
For the Cake:
- 2 cups all-purpose flour
- 1½ cups granulated sugar
- 1 teaspoon baking soda
- 1 teaspoon baking powder
- 1 teaspoon ground cinnamon
- ½ teaspoon salt
- 3 large eggs, room temperature
- ½ cup vegetable oil
- ½ cup unsweetened applesauce
- 2 teaspoons vanilla extract
- 2 cups finely grated zucchini (about 2 medium zucchini)
- 1½ cups fresh blueberries
- 2 tablespoons flour (for coating blueberries)
For the Cream Cheese Frosting:
- 8 oz cream cheese, softened
- ½ cup unsalted butter, softened
- 3 cups powdered sugar
- 1 teaspoon vanilla extract
- Pinch of salt

Step-by-Step Instructions:
Step 1: Prepare Your Pan and Oven Preheat your oven to 350°F (175°C). Grease a 9×13 inch baking pan with butter or cooking spray, then dust lightly with flour. This prevents sticking and ensures easy removal.
Step 2: Prepare the Zucchini Wash and trim the ends of your zucchini. Using a box grater or food processor, finely grate the zucchini. Place grated zucchini in a clean kitchen towel and squeeze out excess moisture. This step is crucial for preventing a soggy cake.
Step 3: Prepare the Blueberries Rinse fresh blueberries and pat them completely dry. Toss the blueberries with 2 tablespoons of flour in a small bowl. This coating prevents them from sinking to the bottom of the cake during baking.
Step 4: Mix Dry Ingredients In a large bowl, whisk together flour, sugar, baking soda, baking powder, cinnamon, and salt. Make sure there are no lumps and everything is evenly distributed.
Step 5: Combine Wet Ingredients In a separate medium bowl, beat together eggs, vegetable oil, applesauce, and vanilla extract until well combined. The mixture should be smooth and uniform.
Step 6: Combine Wet and Dry Ingredients Pour the wet ingredients into the dry ingredients. Gently fold together using a wooden spoon or rubber spatula. Don’t overmix – stop as soon as the flour disappears.
Step 7: Add Zucchini and Blueberries Fold in the prepared zucchini until evenly distributed throughout the batter. Gently fold in the flour-coated blueberries, being careful not to burst them.
Step 8: Bake the Cake Pour the batter into your prepared pan, spreading it evenly with a spatula. Bake for 50-60 minutes, or until a toothpick inserted in the center comes out with just a few moist crumbs.
Step 9: Cool Completely Allow the cake to cool in the pan for 15 minutes, then turn out onto a wire rack to cool completely before frosting. This prevents the frosting from melting.
Step 10: Make the Frosting Beat softened cream cheese and butter together until light and fluffy. Gradually add powdered sugar, vanilla, and salt. Beat until smooth and spreadable.
Step 11: Frost and Serve Once the cake is completely cool, spread the cream cheese frosting evenly over the top. Cut into squares and serve.
What to Serve Blueberry Zucchini Cake With:
This versatile cake pairs beautifully with many accompaniments. Serve it with a hot cup of coffee or cold glass of milk for a classic combination. Fresh whipped cream adds an elegant touch for special occasions.
For a summer gathering, pair slices with vanilla ice cream and fresh berries. The cake also complements herbal teas like chamomile or mint. For brunch, serve alongside fresh fruit salad and yogurt parfaits.
Consider offering it as dessert after a light meal of grilled chicken and vegetables, or as an afternoon treat with lemonade on the porch.

Top Tips for Perfecting Blueberry Zucchini Cake:
Don’t Skip the Zucchini Preparation
Always remove excess moisture from grated zucchini by squeezing it in a clean kitchen towel. Too much moisture will make your cake dense and gummy instead of light and fluffy.
Use Fresh or Frozen Blueberries
Fresh blueberries work best, but frozen ones are fine too. If using frozen, don’t thaw them first – toss them directly in flour while still frozen to prevent bleeding color throughout the cake.
Measure Flour Correctly
Spoon flour into your measuring cup and level it off with a knife. Don’t pack it down or scoop directly from the bag, as this can result in too much flour and a dense cake.
Room Temperature Ingredients
Bring eggs and any dairy ingredients to room temperature before mixing. This ensures better incorporation and a more tender crumb.
Don’t Overbake
Check your cake at 50 minutes. It’s done when a toothpick inserted in the center comes out with just a few moist crumbs. Overbaking will result in a dry cake.
Storage Matters
This cake actually tastes better the next day! The flavors meld together and the texture becomes even more moist. Store covered at room temperature for up to 3 days.
Storing and Reheating Tips:
Room Temperature Storage: Store covered cake at room temperature for up to 3 days. Use a cake dome or cover tightly with plastic wrap to prevent drying out.
Refrigerator Storage: If your kitchen is very warm or the cake is frosted with cream cheese frosting, refrigerate for up to 1 week. Bring to room temperature before serving for best flavor.
Freezing Instructions: Wrap unfrosted cake layers tightly in plastic wrap, then aluminum foil. Freeze for up to 3 months. Thaw overnight in the refrigerator before frosting.
Individual Slice Freezing: Wrap individual frosted slices in plastic wrap and freeze in airtight containers for up to 2 months. Perfect for quick desserts!
Reheating Tips: For room temperature cake, no reheating is needed. If refrigerated, let sit at room temperature for 30 minutes before serving. Avoid microwaving as it can make the cake rubbery.

Frequently Asked Questions
Can I use yellow squash instead of zucchini?
Yes! Yellow squash works perfectly as a substitute for zucchini. The texture and moisture content are very similar, so you won’t notice any difference in the final cake.
How do I know if my zucchini is fresh enough to use?
Fresh zucchini should feel firm and have bright, glossy skin. Avoid zucchini that feels soft, has wrinkled skin, or shows any signs of mold. The fresher the zucchini, the better your cake will taste.
Can I make this cake without eggs?
Absolutely! Replace each egg with ¼ cup unsweetened applesauce or mashed banana. You can also use commercial egg replacers following package directions. The cake will be slightly denser but still delicious.
Why did my blueberries sink to the bottom?
This happens when blueberries aren’t properly coated with flour or when the batter is too thin. Always toss blueberries in flour before folding them in, and make sure your batter is thick enough to support the fruit.
Can I reduce the sugar in this recipe?
Yes, you can reduce the sugar by up to ¼ cup without significantly affecting the texture. Keep in mind that the cake will be less sweet, so you might want to add extra vanilla or cinnamon for flavor.
How long does this cake stay fresh?
Properly stored at room temperature, this cake stays fresh for 3-4 days. In the refrigerator, it will keep for up to a week. The cake actually improves in flavor and moisture after the first day!
Can I make cupcakes instead of a sheet cake?
Definitely! Divide the batter among 24 cupcake liners and bake at 350°F for 18-22 minutes. Test with a toothpick to ensure they’re done. Cupcakes are perfect for parties and portion control.
What’s the best way to grate zucchini?
Use the large holes of a box grater or the shredding attachment on a food processor. Make sure to squeeze out excess moisture afterward. Avoid using the fine holes as they’ll make the zucchini too watery.
Expert Baking Tips for Success:
Testing for Doneness: Besides the toothpick test, gently press the center of the cake. It should spring back when touched. The edges will also start pulling slightly away from the pan sides.
Altitude Adjustments: If baking above 3,000 feet, reduce baking powder by ¼ teaspoon and increase flour by 2 tablespoons. You may also need to increase oven temperature by 15°F and reduce baking time slightly.
Make-Ahead Options: This cake can be made 1-2 days in advance. In fact, it tastes even better after sitting overnight as the flavors meld together beautifully.
Frosting Alternatives: While cream cheese frosting is classic, try maple cream cheese frosting, lemon glaze, or even a simple dusting of powdered sugar for different flavor profiles.
Seasonal Variations: In fall, add ½ teaspoon of nutmeg and substitute half the blueberries with dried cranberries. For winter, try adding orange zest and replacing some blueberries with chocolate chips.
