Moist Chocolate Chip Zucchini Cake Recipe

This Chocolate Chip Zucchini Cake is a moist, tender snack cake that highlights a summertime garden favorite. Similar to a banana snack cake, it’s simple to prepare and works well for an after‑school treat, an afternoon snack, or a light dessert.

The cake texture sits between a quick bread and a light sheet cake: tender, slightly springy, and just sweet enough to satisfy a chocolate craving without overwhelming the zucchini. It pairs perfectly with coffee or tea and keeps well, making it a great option for packing into lunches or serving at casual gatherings.

I often sneak shredded zucchini into savory and sweet dishes. My kids don’t always love visible vegetables, but when I fold zucchini into baked goods like this cake they rarely notice the flavor — only the pleasant moisture and texture it adds. If you enjoy adding vegetables to baking, try zucchini in muffins, fritters, or pasta dishes as well.

Ingredient notes and substitutions

  • Flour — All-purpose flour gives the lightest texture. Whole wheat can be used but will make the cake slightly denser. If you need gluten-free, use a 1:1 gluten-free flour blend formulated to replace wheat flour.
  • Sugar — Granulated cane sugar works well. For a deeper flavor you can substitute part of the cane sugar with brown sugar or use coconut sugar in place of all or part of the cane sugar.
  • Vinegar — This recipe is vegan and uses vinegar combined with baking soda to help the cake rise; apple cider vinegar is recommended, though white distilled vinegar is fine in a pinch.
  • Milk — Use an unsweetened, plain plant milk such as almond, soy, cashew, or rice milk.
  • Oil — A neutral oil like grapeseed, canola, or vegetable oil is best. Melted coconut oil can be used, and applesauce can be substituted for a lower-fat option, though the cake will be more dense.
  • Zucchini — Shred the zucchini and then squeeze out as much liquid as possible using a clean dish cloth or paper towels. Measure 1 cup of shredded zucchini after removing the excess water. Removing moisture prevents a soggy cake.
  • Extras — Chocolate chips are the classic add‑in here; mini or regular chips both work. You can also add up to about 3/4 cup total of chopped nuts (walnuts, pecans, or almonds) combined with or instead of the chips. A simple chocolate drizzle or frosting is optional.

If you choose a chocolate drizzle, melt dairy-free chocolate chips with a tablespoon or two of non‑dairy milk until smooth, then drizzle over the cooled squares. A simple peanut butter or vanilla frosting also pairs well with these bars.

Storage and freezing

Room temperature: Store cooled leftovers in an airtight container for 1–2 days.

Refrigerator: To extend freshness, refrigerate for up to 4–5 days.

Freezer: Wrap the cake well and freeze for up to 3 months. Thaw in the fridge overnight for a whole cake, or bring individual slices to room temperature before serving.

Pro tips and tricks

~ Measure flour with the spoon‑and‑level method: fluff, spoon into the cup, and level off for accurate results.

~ Mix the batter only until just combined. Overmixing will make the cake tough.

~ Thoroughly squeeze the shredded zucchini to remove excess water; this prevents a soggy cake and helps it set properly.

~ Let the cake cool completely on a wire rack before slicing and topping so pieces hold together cleanly.

FAQs

Do I need to peel the zucchini?

No. The skin adds color and nutrients, and the tiny green flecks look appealing in the finished cake. Leave the skin on and simply shred the zucchini.

Is it necessary to squeeze the zucchini?

Yes. Removing excess liquid from shredded zucchini is important to avoid a soggy bake and to help the cake set properly.

Can I make this gluten-free?

You can likely substitute a 1:1 gluten-free flour blend in place of the all-purpose flour. Using a single gluten-free flour without a replacement blend is not recommended.

Recommended Equipment

  • Mixing bowls
  • Box grater or food processor with shredding blade
  • 8×8 baking dish
  • Parchment paper (optional)

Ingredients

  • 2 cups all-purpose flour
  • 1 ½ teaspoon baking powder
  • ½ teaspoon baking soda
  • 1 teaspoon ground cinnamon
  • ¼ teaspoon salt
  • ½ cup cane sugar
  • ⅓ cup grapeseed oil (or canola or vegetable oil)
  • 1 tablespoon apple cider vinegar
  • 1 teaspoon pure vanilla extract
  • ¾ cup unsweetened, plain non-dairy milk
  • 1 cup shredded zucchini (measured after wringing out excess liquid)
  • ½ cup dairy-free chocolate chips

Chocolate Drizzle (optional)

  • ¼ cup dairy-free chocolate chips
  • 1–2 tablespoons non-dairy milk

Instructions

  1. Preheat the oven to 350°F. Line an 8×8 baking dish with parchment paper or lightly grease it.
  2. In a medium bowl whisk together the flour, baking powder, baking soda, cinnamon, and salt.
  3. In a large bowl whisk together the sugar, oil, vinegar, vanilla, and non-dairy milk.
  4. Add the dry ingredients to the wet and stir until just combined. Do not overmix.
  5. Fold in the shredded zucchini and chocolate chips until evenly distributed.
  6. Transfer the batter to the prepared pan and smooth the top. Bake 30–35 minutes, until a toothpick inserted in the center comes out clean or with only melted chocolate but no wet batter.
  7. Let cool in the pan on a rack, then remove and cut into squares.
  8. If using a chocolate drizzle: melt ¼ cup dairy-free chocolate chips with 1 tablespoon non-dairy milk in short bursts in the microwave or over low heat on the stove, stirring until smooth. Drizzle over cooled pieces.

Notes

~ Use the spoon‑and‑level method to measure flour for consistent results.

~ Avoid overmixing: stir just until no dry streaks remain. Small lumps are fine.

~ The easiest way to shred zucchini quickly is with a food processor fitted with a shredding blade; a box grater also works.

~ Thoroughly wring out the shredded zucchini to remove excess moisture and prevent a soggy cake.

~ Allow the cake to cool completely before slicing and applying any drizzle or frosting.
