Easy Keto Chocolate Chip Zucchini Muffins (you won’t miss the carbs)

If you’ve got a lonely zucchini rolling around the crisper and a craving for something sweet-but-not-sugary, you’re in the right kitchen. These keto chocolate chip zucchini muffins are soft, moist, a little toasty at the edges, and packed with tiny pools of chocolate in every bite. They taste like a bakery treat, but the carb count sits low. They’re also easy. No chef hat needed. Just a bowl, a whisk, and a grater that doesn’t try to bite your knuckles.

I started making these during a heat wave when the garden threw zucchini at me like it had a personal vendetta, and I refused to bake anything that needed babysitting. Muffins were the answer. One bowl, quick bake, snack all week. The texture here? Tender and fluffy, not soggy. The chocolate? Dark and sugar-free, so it melts just right without the crash later. And the best part, kids and non-keto friends eat them with zero complaints, sometimes with suspicious speed.

Below, you’ll find a step-by-step guide, simple language, plenty of tips, and all the swaps if your pantry is being awkward today.

Why these muffins are Yummy on Keto

• Low carb and gluten-free: Almond flour and a touch of coconut flour give structure and a soft crumb without wheat.
• Moist without a ton of oil: Zucchini steps in with natural moisture. We squeeze out the extra so muffins don’t turn wet.
• Everyday ingredients: Eggs, butter or oil, vanilla, sweetener, chocolate chips. Nothing fancy.
• Meal-prep friendly: Bake once, snack for days. They freeze like champs.
• Not overly sweet: Just enough to feel like dessert, still good at breakfast with coffee.

What you’ll need (ingredients)

Dry ingredients

• Almond flour — 2 cups / 200 g (super-fine works best)
• Coconut flour — 2 tbsp / 14 g
• Baking powder — 2 tsp
• Ground cinnamon — 1 tsp
• Fine sea salt — ¼ tsp

Wet ingredients

• Large eggs — 3, at room temp if possible
• Granulated keto sweetener — ½ to ⅔ cup (100–130 g), to taste (erythritol, monk fruit blend, or allulose)
• Unsalted butter, melted and slightly cooled — 5 tbsp / 70 g (or avocado oil for dairy-free)
• Vanilla extract — 2 tsp

The stars

• Zucchini, grated — 1½ cups lightly packed / about 170 g (from 1 medium zucchini)
• Sugar-free chocolate chips — ¾ cup / 120 g (dark or semi-sweet style)

Optional but nice

• Sour cream or full-fat Greek yogurt — 2 tbsp (adds tenderness)
• Chopped walnuts or pecans — ¼ cup (for crunch)
• Espresso powder — ¼ tsp (boosts chocolate vibe; won’t taste like coffee)

Note on sweetness: if using allulose, muffins brown faster and taste a bit less sweet than the same weight of erythritol blends, so you may want the higher end of the range.

Tools you’ll use

• 12-cup muffin pan
• Paper liners or silicone liners
• Mixing bowl, whisk, spatula
• Box grater or food processor with shred blade
• Clean kitchen towel or cheesecloth (to squeeze zucchini)
• Cooling rack

Step-by-step instructions for keto Chocolate Chip Zucchini Muffins

1)  Prep the zucchini

Wash and trim the ends. Grate on the coarse side of a box grater. Pile the shreds into a clean towel and twist hard over the sink to squeeze out excess liquid. Do two good squeezes. You want it damp, not dripping. If you skip this, muffins can turn a bit dense.

2)  Heat the oven

Set to 350°F / 175°C. Line your muffin pan. If using paper liners, give them the lightest spray so muffins don’t cling. Silicone doesn’t need it.

3)  Mix dry stuff

In a large bowl, whisk almond flour, coconut flour, baking powder, cinnamon, and salt. Break up clumps so the batter turns smooth later.

4)  Whisk wet stuff

In another bowl (or a big measuring jug), whisk eggs, sweetener, melted butter (or oil), and vanilla until glossy. If adding sour cream or yogurt, whisk it in now. The mix should smell like birthday cake already.

5)  Bring it together

Pour wet into dry. Switch to a spatula and fold until just combined—no dry patches. The batter will look thick but spreadable, like a soft cookie dough.

6)  Fold in the good bits

Add squeezed zucchini and chocolate chips (plus nuts if using). Fold gently so you don’t beat the air out. The batter loosens slightly as the zucchini blends through.

7)  Fill the pan

Scoop into liners, about ¾ full. If you want picture-perfect tops, press a few extra chocolate chips on each muffin.

8) Bake

Bake 18–22 minutes, turning the pan once for even color. Start checking at minute 17. A toothpick should come out clean or with a tiny smudge of melted chocolate, not wet batter. Tops will be lightly golden.

9) Cool

Let muffins rest in the pan 5 minutes (sets the crumb), then lift to a rack to cool. Warm is amazing, but let them settle at least 15 minutes so they don’t crumble.

Texture and taste guide (so you know what “done” feels like)

• Look: Rounded, lightly golden tops with chocolate freckles.
• Touch: Springy when pressed; they bounce back.
• Crumb: Fine, moist, not oily. No soggy line at the base (that’s the sign of zucchini water sneaking in).
• Taste: Gentle sweetness, whisper of cinnamon, buttery note, and little hits of chocolate. No strong zucchini flavor—promise.

Ingredient tips and easy swaps

• Almond flour: Use super-fine blanched almond flour, not almond meal. Meal is coarse and can make muffins gritty.
• Coconut flour: Don’t skip it. A small amount helps bind and gives lift. If you must skip, add 1 extra tbsp almond flour plus ½ tsp xanthan gum; texture won’t be quite the same but still good.
• Sweetener: Erythritol/monk fruit blends keep structure and sweetness close to sugar. Allulose gives softer texture and browns faster. If using straight erythritol and you notice a cooling aftertaste, add ½ tsp vanilla extra or a dot more cinnamon to round it out.
• Butter vs oil: Butter gives a richer flavor; avocado oil keeps things neutral and dairy-free. Coconut oil works too, but melt it and bring close to room temp so it doesn’t seize when it hits the eggs.
• Chocolate chips: Look for sugar-free chips with cocoa butter, not palm oil, for nicer melt. You can chop a bar of stevia-sweetened chocolate if that’s what you have.
• Zucchini: No need to peel. Seeds are fine unless your zucchini is massive with big seeds—if so, scoop them out.

Variations you’ll like

• Double Chocolate: Add 2 tbsp unsweetened cocoa powder to the dry mix and bump sweetener by 1 tbsp to balance.
• Cinnamon Walnut: Swap chocolate chips for chopped walnuts and add ¼ tsp extra cinnamon.
• Orange-Choc Chip: Stir in 1 tsp orange zest and a splash of orange extract. So good with dark chocolate.
• Mocha Chip: Mix ½ tsp espresso powder into the wet ingredients and keep the chocolate chips. Morning muffin, sorted.
• Mini Muffins: Bake in a mini pan for 10–12 minutes. Great for lunch boxes or portion control if your self-control went on holiday.

How to keep muffins moist (without sog)

• Squeeze the zucchini. Hard. This is the big one.
• Measure flour right. Spoon almond flour into cups and level, or just weigh it. Too much packs the batter and dries it.
• Don’t overbake. Pull them when the tops spring back and a tester is clean. A minute or two too long and they lose that tender vibe.
• Cool on a rack. Steam trapped in the pan can dampen the bottoms.

Storage and freezing

• Room temp: Store in an airtight container for up to 2 days. Put a small paper towel inside the container to catch extra moisture.
• Fridge: Up to 1 week. Warm in the microwave for 10–15 seconds to bring back the softness.
• Freezer: Wrap each muffin and freeze in a zip bag up to 3 months. Thaw at room temp or warm straight from frozen in a 300°F / 150°C oven for 8–10 minutes.

Serving ideas

• Breakfast: Split and toast lightly, smear with salted butter or almond butter.
• Coffee break: Warm for 10 seconds so the chips get melty again.
• Dessert plate: Whip a spoon of heavy cream with a drop of vanilla and dollop on top.
• Kid snack: Slice in half and add a thin layer of peanut butter. Disappears quick.

Make-ahead meal prep plan

Bake a double batch on Sunday. Keep 6 in the fridge for the week and freeze the rest. Jot the reheat note on the bag (300°F for 8 minutes) so even sleepy you can re-crisp them. If you’re the macro-tracking type, pre-log one in your app to keep things easy.

Common slip-ups and easy fixes

• Muffins collapse after baking: Usually from too much moisture. Next time, squeeze zucchini more, and weigh ingredients.
• Gritty texture: That’s almond meal or old almond flour. Use fresh, super-fine flour.
• Muffins stick to liners: Let them cool fully, or switch to parchment liners or silicone.
• Too pale with allulose: They brown fast, but sometimes look pale inside. Check doneness with a toothpick; color can be misleading.
• Cooling aftertaste from sweetener: Add ½ tsp vanilla or mix sweeteners (½ allulose + ½ erythritol blend) for a rounder taste.

Nutrition estimate (per muffin, 12 muffins)

• Calories: ~210
• Fat: ~17 g
• Carbs: ~9 g
• Fiber: ~4 g
• Net carbs: ~5 g
• Protein: ~6 g

Numbers will shift a bit based on your chips and sweetener. If you toss in nuts, add a few calories and fat grams. If you go heavy on the chocolate chips (no judgment), net carbs may creep up by 1–2.

The baker’s notes (little things that help)

• Room temp eggs mix smoother and help the batter trap air. If you forgot, set eggs in warm water for 5 minutes.
• Melted butter should be warm, not hot. If it’s too hot, it can scramble the eggs or seize the sweetener.
• Don’t beat the life out of the batter. Gentle folding keeps muffins airy.
• Rest the batter 3 minutes after mixing. Coconut flour hydrates fast; this short rest helps the crumb set.
• Rotate the pan once mid-bake if your oven has hot spots.
• Weighing ingredients isn’t fussy here, it’s friendly. Less guesswork, better texture.

Small backstory (because food with a story tastes better)

A friend swore zucchini did not belong in baked goods—“vegetables are for dinner.” So I made a batch of these and said nothing. He ate two, paused, and asked why they taste so soft. I told him. He blinked. Then took a third like a man making life choices. If you’ve got a veggie skeptic at home, this recipe is your gentle prank. And fair warning: once people learn you make them, they start visiting “by chance” around snack time.

Extra credit: turning this into a loaf or cake

• Loaf: Grease and line an 8.5×4.5-inch loaf pan. Bake at 350°F / 175°C for 45–55 minutes. Tent with foil if browning too quick. Cool fully before slicing.
• Snack cake: Use an 8-inch square pan, bake 25–30 minutes. Great with a quick mascarpone whip (mascarpone + a drop of vanilla).

If you want taller muffin tops

• Fill liners a touch higher (almost to the rim) and bake at 375°F / 190°C for the first 5 minutes, then drop to 350°F / 175°C for the remaining 12–15 minutes. This trick gives a quick rise and nice dome. Keep an eye out; they can brown faster.

Pairing ideas (because coffee deserves company)

• Coffee: A medium roast balances the chocolate.
• Tea: Chai pairs well with cinnamon in the batter.
• Milk: Unsweetened almond or macadamia milk if you want to keep carbs low.
• After-dinner: Warm muffin with a spoon of whipped cream. Simple, still feels like you made effort.

Too dry or wet muffins?

• Dry: Too much almond flour or overbaking. Weigh flour next time and pull them at the first clean toothpick. Add the optional sour cream for extra tenderness.
• Wet: Not enough squeeze on the zucchini. Or maybe your zucchini was very large and watery. Next round, grate, salt lightly, rest 10 minutes, then squeeze.
• Dense: Overmixing can deflate the batter. Fold just until combined, then stop. Your future self will thank you.

Clean-up tips

• Silicone liners make life simple. Muffins pop out, liners rinse clean, no peeling paper off your snack.
• If you used paper liners and they’re greasy, set muffins on a paper towel for a minute after cooling; it wicks extra butter from the bottom.
• Wipe the grater right away or soak it, dried zucchini clings like it pays rent.

Conclusion

Bake these once, and you’ll probably start buying zucchini on purpose, not just when the neighbor leaves it on your porch. The muffins work for breakfast, snack time, or that late-night “I want something sweet but not sugary” moment we all know too well. Keep a stash in the freezer, and future-you will high-five present-you. Quietly. With a mouth full of chocolatey muffin.

Happy baking—save this for later so you can make another batch without hunting for notes. And if your garden starts throwing zucchini again, you’re ready.
