This recipe is a great way to use up extra zucchini and enjoy the warming spices of pumpkin in a simple, fuss-free loaf. It’s perfect for breakfast, snacks, or dessert, and requires minimal prep thanks to the shortcut of cake mix. Before you start, make sure you have all the ingredients and equipment ready for a smooth baking experience.
What You’ll Need
- 1 box (15.25 oz) spice or yellow cake mix
- 1 cup canned pumpkin puree (not pumpkin pie filling)
- 1 cup grated zucchini (about 1 medium zucchini)
- 2 large eggs
- 1/3 cup vegetable oil or melted butter
- 1/4 cup water (if your cake mix calls for it)
- 1 teaspoon ground cinnamon (optional, for extra spice)
- 1/2 teaspoon vanilla extract (optional)
- 1/2 cup chopped walnuts or pecans (optional)
- 1/2 cup chocolate chips or raisins (optional)
- Mixing bowl
- Grater (for zucchini)
- Whisk or spoon
- Loaf pan (8×4 or 9×5 inch)
- Parchment paper or nonstick spray
- Cooling rack
Step-by-Step
- Prepare your pan: Preheat your oven to 350°F (175°C). Grease your loaf pan with nonstick spray or line with parchment paper for easy removal.
- Grate the zucchini: Wash and dry the zucchini. Trim the ends, then grate it using the coarse side of a box grater. No need to peel. After grating, gently squeeze out some excess moisture with a clean kitchen towel or paper towels, but don’t dry it out completely—some moisture is needed for a moist loaf.
- Mix wet ingredients: In a large bowl, whisk together the eggs, oil (or melted butter), pumpkin puree, and vanilla extract (if using) until well combined.
- Add cake mix and spices: Sprinkle in the dry cake mix and cinnamon (if using). Stir gently until just combined. Do not overmix; a few small lumps are okay.
- Fold in zucchini and add-ins: Gently fold in the grated zucchini. If you’re using nuts, chocolate chips, or raisins, add them at this stage.
- Transfer to pan: Pour the batter into your prepared loaf pan and smooth the top with a spatula.
- Bake: Place the pan in the center of your preheated oven. Bake for 45–55 minutes, or until a toothpick inserted into the center comes out clean or with just a few moist crumbs.
- Cool: Let the bread cool in the pan for about 10–15 minutes, then run a knife around the edges and lift it out onto a wire rack to cool completely. This prevents sogginess and helps the texture set.
- Slice and serve: Once fully cooled, slice and enjoy! Store leftovers wrapped in plastic at room temperature for up to 2 days, or refrigerate for up to 5 days.
Common Mistakes
- Overmixing the batter: Stirring too much can make the bread tough and dense. Mix only until ingredients are incorporated.
- Not draining zucchini enough: Excess moisture can make the bread soggy or cause it not to set properly. Squeeze out some liquid but don’t dry it out completely.
- Using pumpkin pie filling: Only use pure pumpkin puree. Pumpkin pie filling has added sugar and spices which can throw off the recipe balance.
- Incorrect oven temperature: Baking at too high or low a temperature can cause the bread to burn outside or stay raw inside. Always preheat your oven and use an oven thermometer if possible.
- Removing from pan too soon: Letting the bread cool slightly before removing from the pan helps it hold together and prevents crumbling.
Tips
- Choose the right cake mix: Spice cake mix gives the most flavor, but yellow or white cake mix also works. If using plain cake mix, add extra cinnamon and nutmeg for flavor.
- Customize add-ins: Try mixing in dried cranberries, chopped dates, or different nuts for variety.
- Double the recipe: Make two loaves at once and freeze one for later. Wrap tightly in plastic and foil before freezing.
- Make muffins: Pour the batter into lined muffin tins and bake for 18–22 minutes for easy grab-and-go treats.
- For extra moisture: Add 1/4 cup unsweetened applesauce or Greek yogurt to the wet ingredients.
- Check for doneness: If the top is browning too quickly, tent with foil for the last 15 minutes of baking.
- Glaze or frost: Drizzle with a simple powdered sugar glaze or cream cheese frosting for a sweeter finish.
Troubleshooting
- Bread is too wet or soggy: This often happens if the zucchini wasn’t drained enough or if too much liquid was added. Next time, squeeze zucchini more thoroughly and measure liquids carefully. If it’s already baked, try slicing and toasting pieces to firm them up.
- Bread is dry or crumbly: Overbaking or using too little oil can cause dryness. Check your oven temperature and bake time, and don’t skip the oil or eggs. To salvage, serve with butter or a glaze.
- Loaf won’t release from the pan: Make sure to grease the pan well or use parchment. If stuck, run a thin knife around the edges and let it cool a bit longer before trying again.
- Bread is undercooked in the middle: This can happen if the pan is too small or the oven is too hot. Bake until a toothpick comes out clean, and cover with foil if the top browns early. Let the bread rest before slicing to finish setting.
- Bread falls in the center: Too much liquid, underbaking, or opening the oven door too often can cause sinking. Make sure to measure ingredients accurately and avoid peeking during baking.
Frequently Asked Questions
- Can I use fresh pumpkin instead of canned?
- Yes, just make sure it’s well pureed and not watery. Roasted and mashed pumpkin works best for a smooth texture.
- Do I need to peel the zucchini?
- No, the skin is soft and blends in well. Just wash thoroughly before grating.
- Can I make this bread gluten-free?
- Yes, use a gluten-free cake mix and check that all other ingredients are gluten-free.
- How do I store pumpkin zucchini bread?
- Store wrapped at room temperature up to 2 days, or in the fridge up to 5 days. For longer storage, freeze slices up to 2 months.
- Can I reduce the sugar?
- The cake mix contains sugar, so reducing it is tricky. For less sweetness, use an unsweetened cake mix if available, or balance with tart add-ins like cranberries.
- What if I don’t have a loaf pan?
- You can use a muffin tin, bundt pan, or 8×8-inch square pan—just adjust baking time and check for doneness earlier.
