Zucchini cake. Just reading that, you imagine something dense, a bit bland, tasting like a forced diet. Yet, this cake is probably one of the moistest you can make this year, and the zucchini, nobody tastes it or sees it.
Cut a slice and look closely. The crumb is a warm beige, lightly speckled with pale green, with pockets of melted chocolate still glistening. The aroma that rises during baking blends warm vanilla and cocoa — something between a brownie and a Sunday loaf bread. Under your fingers, the surface is slightly moist, elastic, with that resistance characteristic of well-made cakes. Neither dry nor sticky.

Ingredient Notes
All the simple pantry ingredients for a healthy and indulgent cake.
- Zucchini : One large or two small, same difference. Grate it on the coarse side of the grater — the one that makes long shreds — and above all, don’t squeeze it. Everyone reflexively squeezes zucchini. Here that’s exactly what not to do: its water is the main source of moisture in the cake.
- Applesauce : Unsweetened, no added sugar. The individual little jars work perfectly. Not sweetened applesauce: the brown sugar is already there for that. Applesauce plays exactly the same role as butter in terms of texture, without the fat that weighs things down.
- Flour blend : Half all-purpose flour, half white whole wheat flour. The whole wheat flour adds a faint nutty flavor and structures the crumb better. If you don’t have it, all-purpose flour alone works, but the cake will be a bit less interesting in the mouth.
- Chocolate chips : Semi-sweet, not chopped baking chocolate. Chips melt differently: they keep a recognizable shape in the crumb without creating large hard sheets. About 80 to 100 g for the pan.
- Brown sugar : It adds a subtle caramelized warmth that white sugar wouldn’t have. Regular brown sugar or light muscovado — no need to look for anything special.
Why I never squeeze the zucchini anymore
The first time you make a recipe with grated zucchini, the natural reflex is to squeeze it in a towel. That’s what you do for fritters, for croquettes, for anything that needs to be crispy. Here, that’s the classic mistake. The grated zucchini goes directly into the bowl with the other wet ingredients — its water integrates into the batter during mixing and keeps working during baking. Result: a crumb that stays tender for days. Without that water, the cake would still be good, but it would lose its signature.
The applesauce that really changes things
Two tablespoons of melted butter is the amount that remains in this recipe. The rest was replaced by applesauce, and honestly you can’t tell the difference. In the mix, it gives the batter a thick, smooth consistency, like thick honey slowly dripping from the spoon. It adds binding, moisture, and a very faint underlying sweetness you wouldn’t be able to name blindfolded. This isn’t a diet trick. It’s simply a better way to get a tender cake.
The one thing you really must not do when mixing
Dry ingredients on one side — flours, sugar, baking soda, salt, chips — and wet on the other. The trick of tossing the chips in flour before mixing everything is useful: they get coated with flour and are less likely to sink to the bottom during baking. When you incorporate the liquids into the dry, mix just enough to make the flour traces disappear. Twenty spoonfuls, maximum. Cake batter should not be smooth like pastry cream — a few lumps are exactly where you stop. Over-mixing activates the gluten and turns the crumb rubbery instead of tender.
Baking at a low temperature, the detail that changes the result
Oven at 160°C, lower than you’d think for a cake. This gentle heat lets the center cook quietly without the crust browning too fast. The top takes on a golden color like light caramel, with a characteristic central crack that opens after twenty minutes — a sign that the rise is happening properly. Around the thirty-minute mark, a powerful scent of hot chocolate starts spreading through the kitchen. That’s a good sign, but not yet the time to take the pan out. Count between 45 and 55 minutes depending on your oven, and check with a toothpick: it should come out clean, or with a few dry crumbs, never wet batter.
Tips & Tricks
- Let the cake cool 10 minutes in the pan before unmolding — the crumb is still fragile when very hot and the slice can break. 10 minutes in the pan, then on a rack until room temperature before cutting.
- Store the cake wrapped in plastic wrap in the refrigerator. It keeps for up to a week and is, honestly, better the next day when the flavors have had time to settle.
- If your zucchini is large and the skin is thick and a bit tough, peel it before grating. For small summer zucchini, the thin skin is fine and gives those little green specks in the crumb.
Can you really taste the zucchini in this cake?
No, not at all. Zucchini has almost no pronounced flavor raw, and in baking it completely disappears. It just leaves a few little green specks in the crumb and, above all, a moisture that other cakes don’t have. That’s what makes it a good trick to play on picky kids.
Can I replace the applesauce with something else?
A well-mashed ripe banana works, but it changes the flavor of the cake — you’ll have a fairly present banana undertone. Plain yogurt or thick cream can also do the job in a pinch. Unsweetened applesauce remains the most neutral and easiest to measure option.
How do I know when the cake is done without constantly opening the oven?
Wait at least 45 minutes before checking — if you open too early, the center can collapse. Insert a toothpick at the thickest part of the cake: it should come out clean or with a few dry crumbs. Wet batter sticking means 5 to 10 more minutes.
How long does this cake keep, and how should I store it?
At room temperature it keeps 2 days, but it’s much better in the refrigerator where it keeps up to a week in an airtight container or well wrapped in plastic wrap. The flavors concentrate the next day — that’s often when it’s best.
Can I freeze this cake?
Yes, no problem. Let it cool completely, cut into individual slices, and freeze each slice separately in plastic wrap. It keeps up to 3 months. Just take out a slice the day before in the refrigerator, or microwave for 30 seconds.
Why use two types of flour?
All-purpose flour gives lightness and a tender crumb, whole wheat flour provides structure and a slight nutty flavor. You can use only one if needed — with 100% whole wheat flour the cake will be a bit denser and more rustic, with 100% all-purpose it will be lighter but less interesting in flavor.
Ultra-Moist Zucchini Chocolate Cake
American
Breakfast and Snack
A moist and generous cake where the zucchini completely disappears in taste, applesauce replaces almost all the butter, and the chocolate chips do the rest.
Ingredients
- 125g all-purpose flour (unbleached preferred)
- 120g white whole wheat flour (or whole wheat flour)
- 150g brown sugar (cane sugar)
- 1 tsp baking soda
- 1/2 tsp salt
- 1 tsp vanilla extract
- 90g semi-sweet chocolate chips
- 1 large egg
- 30g melted butter (2 tablespoons)
- 120g unsweetened applesauce
- 240g grated zucchini, unsqueezed (about 1 large zucchini)
Instructions
- 1Preheat the oven to 160°C. Grease a 23×13 cm loaf pan with cooking spray or butter.
- 2In a large bowl, whisk together both flours, brown sugar, baking soda, and salt until combined.
- 3Add the chocolate chips to the dry ingredients and mix to coat them well with flour — they will be less likely to sink to the bottom during baking.
- 4In a second bowl, whisk the egg, vanilla, melted butter, applesauce, and grated zucchini. Do not squeeze the zucchini; its water is essential.
- 5Pour the wet ingredients over the dry and mix with a spoon until the flour is just incorporated. Stop as soon as there are no more white streaks — a few lumps are normal.
- 6Pour the batter into the pan and lightly smooth the top. Bake for 45 to 55 minutes.
- 7Check doneness with a toothpick inserted in the center: it should come out clean or with a few dry crumbs.
- 8Let cool 10 minutes in the pan, then turn out onto a wire rack and let cool completely before slicing.
Notes
• Storage: wrap in plastic wrap and store in the refrigerator for up to 1 week. The cake is better the next day.
