Cook time: 22 minutes
Total time: 37 minutes
Intensity Level: 2/10 (Easy – requires basic mixing and grating)

These Low Carb Zucchini Muffins are a game-changer for anyone on a ketogenic, gluten-free, or diabetic-friendly diet. They are incredibly moist, tender, and packed with hidden vegetables. Unlike traditional zucchini bread that is loaded with sugar and flour, these muffins use almond flour and coconut flour to keep the net carbs under 4 grams per serving.

Why you will love this recipe:

Freezer-friendly – Make a double batch and save for busy mornings.
Kid-approved – The zucchini disappears into the crumb.

Two ways – Make them savory with cheddar and chives, or sweet with cinnamon and vanilla.

Ingredients

For the Muffins (Sweet Version – Default)

2 large eggs (room temperature)
¼ cup (60 ml) melted coconut oil or unsalted butter
¼ cup (60 ml) unsweetened almond milk
1 tsp vanilla extract
½ cup (50g) granulated erythritol or monk fruit sweetener (or allulose)
2 cups (220g) packed, grated zucchini (about 1 medium zucchini)

1 ½ cups (150g) fine blanched almond flour
¼ cup (30g) coconut flour
1 tsp baking powder
½ tsp baking soda
¼ tsp salt
1 tbsp ground cinnamon (for sweet version)
Optional mix-ins: ⅓ cup sugar-free chocolate chips or chopped walnuts

For Savory Version (Swap/Add)

Omit vanilla extract and cinnamon.
Add ½ tsp garlic powder, ¼ tsp black pepper.
Fold in ½ cup shredded sharp cheddar cheese + 2 tbsp chopped fresh chives.

Reduce sweetener to 2 tbsp (or omit entirely).

Instructions

1. Prepare the Zucchini (5 min)

Grate the zucchini using the large holes of a box grater. Do not peel it – the skin holds nutrients and moisture. Place the grated zucchini in a clean kitchen towel or several layers of paper towels. Squeeze firmly over the sink to remove as much liquid as possible. You should remove about ½ cup of water. This step prevents soggy muffins.

2. Preheat & Line (5 min)

Preheat your oven to 350°F (175°C). Line a 12-cup standard muffin tin with paper liners or grease generously with coconut oil. Silicone liners work best for low-carb bakes because they release easily.

3. Mix Wet Ingredients & Sweetener (3 min)

In a large mixing bowl, whisk together the eggs, melted coconut oil, almond milk, vanilla (if using sweet version), and granulated sweetener until smooth and slightly frothy. The erythritol will not fully dissolve – that is fine.

4. Add Dry Ingredients (2 min)

Add the almond flour, coconut flour, baking powder, baking soda, salt, and cinnamon (for sweet version) directly to the wet mixture. Stir with a rubber spatula until just combined. The batter will be thick – thicker than standard muffin batter.

5. Fold in Zucchini (1 min)

Add the squeezed, dry grated zucchini to the batter. Fold gently until evenly distributed. If using any mix-ins (chocolate chips, cheese, nuts), fold them in now. Do not overmix or the muffins will be dense.

6. Fill Muffin Cups (2 min)

Divide the batter evenly among the 12 muffin cups. Each cup should be about ¾ full. Use a small cookie scoop or two spoons – the batter is sticky. Smooth the tops with wet fingers if desired.

7. Bake (22 min)

Bake on the middle rack for 20–24 minutes. The muffins are done when:

The tops are golden brown.
A toothpick inserted in the center comes out clean or with a few moist crumbs (not wet batter).
The edges pull away slightly from the pan.

8. Cool (10 min – critical step)

Let the muffins cool in the pan for 10 minutes. Then transfer them to a wire rack to cool completely. Low-carb baked goods are fragile when hot. Do not skip the in-pan cooling.

Recipe Notes & Troubleshooting

Why are my muffins wet in the middle?
You did not squeeze the zucchini enough. Next time, press harder or let the salted zucchini sit for 10 minutes before squeezing.

Can I use only almond flour?
No. Coconut flour is essential for structure. Without it, the muffins will be greasy and flat.

My sweetener made the muffins cold/cool in the mouth?
That is a known effect of erythritol. Use allulose or monk fruit with no erythritol to avoid the “cooling” sensation.

Can I make these vegan?
Replace eggs with 2 flax eggs (2 tbsp ground flaxseed + 6 tbsp water, let gel 5 min). Add ¼ tsp extra baking powder. Texture will be denser but still good.

What if I only have a mini muffin pan?
Bake for 12–14 minutes. Makes about 24 mini muffins. Adjust nutrition by dividing total recipe yields.

The Last of the Recipe (Chef’s Note)

“The secret to perfect low-carb zucchini muffins is not the flours – it is patience with the squeezing. Most people skip this step, then blame the recipe. Squeeze until your hands ache, then squeeze once more. Your muffins will be light, moist, and nobody will ever guess they are low carb. Keep a batch in your freezer for days when cravings hit.”
