How to Make It: Step-by-Step Instructions
Step 1: Prep Pan and Oven
Preheat your oven to 350°F (177°C). Line an 8.5 x 4.5-inch metal loaf pan with a sheet of parchment paper, leaving a couple of inches of overhang on the long sides to act as handles for easy removal later. Lightly mist the paper with avocado oil spray.
Step 2: Grate and Sweat the Zucchini
Wash 1 medium zucchini and trim off the stem end (no need to peel the green skin). Use the coarse side of a box grater to shred enough zucchini to yield 1.5 cups (about 7 ounces). Place the shredded zucchini into a clean kitchen towel, gather the corners over the sink, and wring out the excess water. The Pro Secret: You want to squeeze until the zucchini is damp rather than bone-dry. Leaving a slight touch of natural juice ensures your bread stays moist without turning soggy.
Step 3: Whisk the Dry Blend
In a large mixing bowl, combine 2 cups of superfine blanched almond flour, 1/4 cup of golden flaxseed meal, 3/4 cup of granulated erythritol sweetener, 2 teaspoons of ground cinnamon, 1/4 teaspoon of ground nutmeg, 1.5 teaspoons of baking powder, and 1/2 teaspoon of fine sea salt. Whisk vigorously for 30 seconds to break up any lumps of nut flour.
Step 4: Beat the Wet Ingredients
In a separate medium bowl, whisk together 3 large room-temperature eggs, 1/3 cup of melted (and cooled) unsalted butter, and 1.5 teaspoons of pure vanilla extract for 60 seconds until pale and frothy.
Step 5: Fold the Batter Together
Pour the wet egg mixture into the dry flour blend. Use a silicone spatula to fold the ingredients together until a thick, uniform batter forms. Fold in your wrung-out shredded zucchini (and 1/2 cup of chopped walnuts if using) until evenly distributed throughout the dough.
Step 6: Bake to Golden Perfection
Scrape the batter into your prepared loaf pan, using the back of a spoon to smooth out the top into an even layer. Bake at 350°F for 45 to 55 minutes. The bread is ready when the top is deep golden brown and a toothpick inserted into the very center comes out clean or with a few dry crumbs.
Step 7: Cool to Structure
Let the bread cool in the hot pan set on a wire rack for 20 minutes. Then, use the parchment paper handles to lift the loaf out onto the wire rack to cool completely before slicing.
Pro Tips for Best Recipe
Use a Metal Pan: Always bake grain-free quick breads in a metal loaf pan rather than glass or ceramic. Metal conducts heat quickly and evenly, allowing the outer crust to set before the inside overcooks.
Measure Almond Flour by Weight: Nut flours pack tightly into measuring cups. For exact consistency, use a kitchen scale to measure out 224 grams of almond flour rather than scooping with a cup.
Warm Your Eggs: Cold eggs directly from the fridge will instantly freeze melted butter into tiny hard specks when mixed. Place cold eggs in a bowl of warm water for 5 minutes before cracking them.
Do Not Slice Hot: Resist the temptation to cut into the loaf right out of the oven! Gluten-free breads require cooling time for the fats and starches to set, ensuring clean, non-crumbly slices.
Storage
- To Store: Keep leftover slices in an airtight container lined with a dry paper towel inside the refrigerator. Because of its high moisture content, grain-free bread can spoil on a warm counter; chilling keeps it fresh and moist for up to 7 days.
- To Freeze: Wrap individual slices tightly in plastic wrap, then store them in a freezer zip-top bag for up to 3 months. Thaw a slice on the counter for 15 minutes before enjoying.
- To Reheat: Warm a slice in a toaster oven or bake at 300°F (150°C) for 3 to 5 minutes, then spread a generous pat of salted butter over the top.
Frequently Asked Questions
Can I substitute coconut flour for almond flour?
No, coconut flour cannot be substituted 1:1 for almond flour. Coconut flour acts like a sponge, absorbing roughly four times as much liquid, which will result in a dry, egg-heavy loaf.
Why did my bread turn out soggy in the center?
A wet center usually means too much water was left in the zucchini or a thick glass baking pan was used. Ensure you squeeze out excess liquid and stick to metal loaf pans for an even bake.
Do I need to peel the zucchini skin?
Not at all! Zucchini skin is very thin and tender, adding dark green flecks, beneficial fiber, and nutrients without affecting the sweet cinnamon flavor.
Can I make this recipe dairy-free?
Yes! Swap the melted butter with an equal amount of melted refined coconut oil or avocado oil for a completely dairy-free slice.

Ingredients
- The Grain-Free Dry Base
2 cups (224g) blanched superfine almond flour
¼ cup golden flaxseed meal
¾ cup granulated erythritol or allulose sweetener
2 tsp ground Ceylon cinnamon
¼ tsp ground nutmeg
1½ tsp baking powder
½ tsp fine sea salt
- The Wet Batter Fillers
3 large whole eggs (room temperature)
⅓ cup unsalted butter (melted and cooled)
1½ tsp pure vanilla extract
1½ cups fresh zucchini (shredded and squeezed; approx. 7 oz)
½ cup chopped walnuts (optional)
Instructions
Preheat oven to 350°F (177°C). Line an 8.5 x 4.5-inch metal loaf pan with parchment paper, leaving overhang on the sides.
Shred 1.5 cups of unpeeled zucchini. Wrap in a clean kitchen towel and squeeze over the sink to remove excess liquid.
Whisk almond flour, flaxmeal, sweetener, cinnamon, nutmeg, baking powder, and salt together in a large bowl.
In a separate bowl, whisk room-temperature eggs, melted butter, and vanilla for 60 seconds until frothy.
Fold wet ingredients into dry flour until smooth. Stir in the zucchini (and walnuts). Spread into pan and bake at 350°F for 45 to 55 minutes until a central toothpick comes out clean.
Cool in the pan for 20 minutes, then lift out onto a wire rack to cool fully before slicing.
Notes
Wring Lightly: Do not squeeze the zucchini completely bone-dry; leave a tiny touch of moisture to keep the crumb soft. Stick to Metal: Glass pans cook unevenly and can leave the middle wet while burning the outer edges. Use Room Temp Eggs: Prevents the melted butter from solidifying into cold bits when mixed into the wet batter. Cool Before Slicing: Gluten-free loaves set as they cool down; slicing too early will cause slices to crumble. Store Cold: Keep slices refrigerated in an airtight container for best texture and freshness.
