Eggless zucchini coffee cake is a soft, tender crumb cake that turns your summer zucchini into breakfast — no eggs needed. A buttery cinnamon crumb tops the moist, lightly spiced cake, and the zucchini melts right in, so the kids never spot the veggie. It’s egg-free by design, made from simple pantry staples — no replacers to hunt down. One cozy bake the whole table can share: this is the one.
Oriana’s Thoughts On The Recipe
When the grocery bag (or the garden) overflows with zucchini in July, I want more than another loaf of bread — I want something that feels like a treat everyone can dig into. This eggless zucchini coffee cake is that treat: soft and cinnamon-scented, with a crumb topping my kids fight over, and not a single egg in sight.
Honestly, I just love this cake. It’s the one I reach for on a slow breakfast or brunch, when we have guests, or when we just want a little treat on an ordinary day. It’s also the only way I can get Vicky to eat zucchini — sneak it into something sweet, and she never suspects a thing. And it couldn’t be easier: measure, mix, and bake, with no mixer and no complicated steps — it comes out moist, soft, and perfectly cinnamony every time.
After more than 13 years of baking egg-free for my own family, I’ve learned that the secret to a tender zucchini cake is to stop fussing with it — no wringing, no squeezing, just let the zucchini do its thing — and I tested this one in my own kitchen until it was exactly right. It’s the kind of cozy, no-one-left-out bake this little corner of the internet is all about.
Why You’ll Want to Try My Recipe
- Egg-free by design. No eggs and no replacers — safe for an egg allergy, and soft and tender all on its own.
- That cinnamon crumb topping. Buttery, sweet, and lightly crunchy — it’s the best bite of every piece.
- Moist and tender, never soggy. The zucchini melts in for a soft crumb without a wet middle — and there’s no blotting or squeezing to fuss with.
- A hidden veggie kids won’t notice. All they taste is cinnamon coffee cake; the zucchini disappears right into the crumb.
- A smart way to use up summer zucchini. Turns that endless August harvest into something everyone actually wants seconds of.
- Tested by a real allergy mom in a real family kitchen. Not a test-kitchen claim — my own kitchen, my own family, until it was right.
Why This Cake Works Without Eggs?
Eggs usually add structure and lift. Here, the yogurt and the quick buttermilk (milk plus apple cider vinegar) do that job — the acid activates the baking powder and baking soda for a light rise, while the oil keeps everything soft and moist for days. There’s no egg replacer to buy and nothing unusual in the bowl. It’s built egg-free from the very first ingredient, not adapted after the fact.
How to Get a Tender (Not Soggy) Zucchini Coffee Cake?
Here’s the best part: this cake is genuinely forgiving. Zucchini is almost all water, and instead of fighting that, this recipe puts it to work — so you don’t need to blot, squeeze, or wring it at all. Just grate it on the large holes, add it straight in, and don’t pack it down when you measure. The only real rule is to stir the batter just until the flour disappears; overmixing is the one thing that turns a soft crumb dense. I tested it with 1/3 cup milk and un-blotted zucchini, and it baked up perfectly tender every time.
Ingredients You’ll Need, Substitutions & Notes
Scroll down to the recipe card for all the details, including measurements and instructions.
Most of these are pantry staples you already have — a few are worth a quick note.
- Zucchini — the moisture and the magic. Grate it and add it straight in — no need to blot or squeeze out the water. That moisture is exactly what keeps the cake soft and tender. And no need to peel — the skin softens and disappears as it bakes.
- Plain yogurt or sour cream — one of the egg-free workhorses. It adds moisture, a little richness, and a gentle tang that keeps the cake soft. Full-fat works best.
- Apple cider vinegar. With the milk, it makes a quick buttermilk; the acid reacts with the baking soda for lift and a tender crumb — which matters even more when there are no eggs.
- Brown and granulated sugar. Brown sugar brings moisture and a little caramel note; granulated keeps the texture light. You’ll use brown sugar in the crumb topping too.
- Butter for the crumb. Melted butter is what pulls the topping together into those chunky, cookie-like crumbles.
Food Allergy Notes & Swaps
This recipe does not contain eggs, tree nuts, peanuts, soy, sesame, fish, or shellfish as ingredients. Manufacturing lines change — read every label every single time, even brands you have used before. That habit has never steered me wrong.
Need Dairy-Free or Gluten-Free?
If you are navigating additional dietary needs alongside the egg-free requirement, I have detailed guides for both: How I Replace Dairy in My Egg-Free Recipes – Baking Without Eggs and Gluten
Ingredient Swap Suggestions
- Dairy-Free: To make this recipe dairy-free, you can easily swap out the dairy ingredients for non-dairy alternatives.
- Butter: Substitute butter with dairy-free butter substitutes. Miyoko’s Creamery Organic Vegan Butter, Trader Joe’s brand vegan butter, and Earth Balance Vegan Buttery Sticks are my favorite butter substitutes for baking. For the best flavor, use a vegan butter that tastes good. Use sticks or blocks, not tub (spreadable) butter.
- Yogurt: Use your favorite brand of plain, unsweetened non-dairy yogurt.
- Milk: You can use your favorite non-dairy milk, like soy or oat milk.
- Gluten-Free: Use a gluten-free, all-purpose flour blend. Look for a gluten-free flour blend specifically formulated for baking, as it will have the right combination of flours and starches to mimic the texture of wheat flour. My favorite is Better Batter Original Blend. I also like Doves Farm Freee Gluten-Free All-Purpose Flour, but this blend does not contain xanthan gum, so you need to add 1/4 teaspoon of xanthan gum per cup (140 g) of gluten-free flour blend.
What I Learned Testing This Recipe
- This one earned its “foolproof” label. I tested it as both an 8×8 cake (45 minutes) and a 9×5 loaf (55 minutes), and it came out tender and cozy both ways — the very same batter, two different bakes.
- The biggest surprise: you don’t need to blot or squeeze the zucchini at all. I skipped it completely, and the crumb was soft, never soggy — the zucchini’s moisture is doing exactly what you want.
- One small thing that makes life easier: line the pan with parchment and leave an overhang on the sides, so you can lift the whole cake straight out to cool and slice — no fighting to unmold it. Easy, forgiving, and honestly hard to mess up.

Tips & Troubleshooting
- Skip the blotting. There’s no need to squeeze or blot the zucchini — its moisture is what keeps the cake soft and tender. Just grate it and add it straight in.
- Don’t overmix. Stir just until the flour disappears; overmixing builds a dense, tough crumb.
- Keep the crumbs chunky. Mix the topping with a fork just until it clumps — over-stirring turns it to paste. Press it lightly into the batter so it stays put.
- Tent it if it browns too fast. If the top colors before the center sets, lay foil loosely over it for the last several minutes.
- Gummy in the middle? That usually means the cake was slightly underbaked or your oven runs cool — make sure it’s fully preheated, check it with an oven thermometer, and give it the full bake time until a toothpick comes out clean.
- Cool before slicing. Coffee cake firms up as it cools; slicing it warm can tear the tender crumb.
Storage and Freezing Instructions
Store the cooled cake covered at room temperature for up to 3 days, or refrigerate for up to 5 days.
Freeze the fully cooled cake (whole or in squares) wrapped tightly for up to 2 months. Thaw at room temperature.

Ingredients
For the Cinnamon Crumb Topping:
- 1/2 cup (70 g) all-purpose flour
- 1/3 cup (67 g) brown sugar
- 1 teaspoon ground cinnamon
- 1/4 teaspoon kosher salt
- 3 tablespoons (42 g) unsalted butter, melted
For the Cake:
- 2 cups (280 g) all-purpose flour
- 1 1/2 teaspoons (6 g) baking powder
- 1/2 teaspoon (3 g) baking soda
- 1 teaspoon kosher salt
- 1 1/2 teaspoons ground cinnamon
- 1/4 teaspoon ground nutmeg
- 1/2 cup (120 g) plain yogurt or sour cream
- 1/2 cup (120 ml) neutral oil
- 1/3 cup (80 ml) milk
- 1/2 cup (100 g) granulated sugar
- 1/2 cup (100 g) brown sugar
- 1 tablespoon (15 ml) apple cider vinegar
- 2 teaspoons (10 ml) pure vanilla extract
- 1 1/2 cups (180 g) grated zucchini (no need to blot)
Instructions
- Make the crumb topping: Combine the flour, brown sugar, cinnamon, and salt in a bowl. Stir in the melted butter, then use a fork to bring it together into large, chunky crumbles — don't over-mix, or it turns to paste. Refrigerate until you make the cake batter.
- Prep the pan and oven: Preheat the oven to 350°F (180°C). Line an 8×8-inch (or 9×9-inch) square pan with parchment, leaving an overhang on the sides, and lightly grease with baking spray with flour.
- Mix the dry ingredients: Whisk the flour, baking powder, baking soda, salt, cinnamon, and nutmeg together in a large bowl until well combined.
- Mix the wet ingredients: In another bowl, whisk the yogurt, oil, milk, both sugars, apple cider vinegar, and vanilla until smooth.
- Combine: Pour the wet ingredients into the dry and gently whisk until just combined — don't overmix. The batter will be thick. Stir in the grated zucchini and mix until evenly distributed.
- Assemble: Spread the batter evenly in the prepared pan. Sprinkle the crumb topping over the top and gently press it in so it sticks.
- Bake: Bake for 40–45 minutes, until a toothpick inserted in the center comes out clean and the topping is golden. Start checking at 40 minutes; tent loosely with foil if the top browns too fast.
- Cool: Cool in the pan for 10 minutes, then lift out using the parchment overhang and cool before slicing.
- No need to blot the zucchini — its moisture keeps the crumb tender.
- Use room-temperature yogurt and milk so they blend evenly.
- Cool before slicing so the tender crumb doesn’t tear.

Variations & Additions To Try
- Add chocolate chips. Fold 1/2 cup into the batter for a kid-favorite twist, just like my chocolate chip zucchini bread.
- Add nuts to the crumb. A handful of chopped walnuts or pecans in the topping adds a little crunch.
- Make it a party cake. A simple vanilla glaze drizzled over the cooled cake dresses it up for a holiday or brunch.
- Make it a loaf. The same batter bakes into a beautiful 9×5 loaf — about 55 minutes at 350°F (180°C). Add a thin line of cold butter down the center before baking for that signature bakery crack.
- Extra spice. A pinch more cinnamon or nutmeg deepens the cozy, bakery flavor
Serving Suggestions
This is an anytime cake — a warm slice with your morning coffee, an after-school snack, a brunch spread, or a bake-sale table. It’s lovely plain, and even better slightly warm, when the crumb topping tastes fresh from the oven.
Do you think this recipe would work with a gluten free flour mix?
Yes, absolutely, Donna! I’ve made it with a 1:1 gluten-free all-purpose blend and it works well — just look for one formulated for baking (Better Batter is my go-to). If your blend doesn’t already include xanthan gum, add about ¼ teaspoon per cup of flour so it holds together nicely. Would love to hear how it turns out!
Hi Oriana, thanks so much for this zucchini cake, it is actually delicious and tastes like apple cake! I baked it in a 9×9″ pan and it didn’t rise much – I think the tin was too big! It was also dense and heavy and no way looks like the nice crumb you have in your Pic. My cake looks more like a pudding, but it was definitely done after 40 mins with the skewer coming out clean. Where do you think I erred? Would love to hear from you. Regards, Diane (Johannesburg, SA)
Hi Diane! Thank you so much for baking this all the way over in Johannesburg — and for the kind words about the flavor!
Let’s figure out that dense, pudding-y texture together, because the 9×9 pan actually isn’t the culprit (the recipe works in either an 8×8 or a 9×9, so you were fine there). Nine times out of ten, a heavy, low-rising crumb comes down to one of three things:
1- the batter got overmixed (stir just until the flour disappears — even a little extra stirring builds a dense, gummy crumb),
2- the zucchini was packed down when measured (grate it on the large holes and spoon it in loosely, since too much adds extra moisture),
3- or the baking powder and soda are past their prime (old leavening is the usual reason a cake bakes up flat).
Since yours came out pudding-like, my best tip is to blot the zucchini next time — just press the grated zucchini between a few paper towels or a clean kitchen towel to squeeze out the extra water before folding it in. That alone should make a big difference. I’d also double-check your oven is fully preheated. And I just added a short how-to video right on the recipe card so you can see the texture and steps as you go. Try it once more with those tweaks and I think you’ll get that light, tender crumb — let me know how it goes, I’m happy to help troubleshoot!
