👩‍🍳 Instructions

1. Preheat & prepare the pan

Preheat your oven to 350°F (175°C).
Line a 9-inch round cake pan with parchment paper (cut a circle for the bottom) and lightly grease the sides with coconut oil.

2. Grate the zucchini

Wash the zucchini (peel is fine). Grate it on the large holes of a box grater. You should have about 1½ lightly packed cups. Do not squeeze – set it aside in a small bowl.

3. Combine dry ingredients

In a large mixing bowl, whisk together the almond flour, baking soda, and salt.

4. Combine wet ingredients

In a separate small bowl or directly into the dry ingredients (if you’re bold), whisk the eggs, honey, melted coconut oil, lemon juice, lemon zest, and vanilla until smooth and emulsified.

5. Mix batter

Pour the wet mix into the dry mix. Stir with a spatula until just combined. The batter will be thick but wetter than regular cake batter – that’s normal.

6. Add zucchini and nuts

Fold in the grated zucchini (plus nuts if using) until evenly distributed. The batter will become very moist – this is the magic.

7. Bake

Scrape batter into the prepared pan and smooth the top. Bake for 32–38 minutes until:

• The top is 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

Let the cake cool in the pan on a wire rack for 10 minutes. Then run a knife around the edge, flip it out onto the rack, peel off the parchment, and flip it right-side up to cool completely (another 10–15 minutes).

9. Serve

Dust with powdered sugar or drizzle with a simple lemon glaze (mix 2 tbsp lemon juice + ½ cup powdered sugar). Serve at room temperature.

💡 Tips for success

• Don’t squeeze the zucchini – That water replaces gluten’s moisture-holding ability. It keeps the cake tender, not soggy.

• Zest the lemons before juicing – Much easier.

• Room temperature eggs – They emulsify better with the oil. If you forget, place eggs in warm water for 5 minutes.

• Almond flour note – Use fine, blanched almond flour (not almond meal, which has skins and is coarser). Bob’s Red Mill or Kirkland works great.

❄️ Storage & freezing

• Counter: Sealed container for 2 days (it’s very moist – longer than that, refrigerate).

• Fridge: Up to 5 days. Bring to room temp or gently microwave for 10 seconds.

• Freezer: Wrap slices tightly and freeze for up to 3 months. Thaw overnight in the fridge.

🌱 Variations

• Vegan option: Replace eggs with 3 flax eggs (3 tbsp flax meal + 9 tbsp water, let gel). Add ¼ tsp baking powder for lift. Texture will be denser but still delicious.

• Dairy-free lemon glaze: Use coconut cream powder + lemon juice, or just skip it.

• Chocolate twist: Add 3 tbsp unsweetened cocoa powder + 2 extra tbsp honey.

• Keto: Replace honey with ⅓ cup allulose or erythritol + ½ tsp stevia drops. Net carbs drop to ~4g per slice.
