Kick things off by preheating your oven to 350°F (175°C). Lightly grease a 9x5 inch loaf pan (or a 12-cup muffin tin for muffins) with butter or cooking spray.
In a roomy bowl, whisk together the almond flour, salt, cinnamon, sugar-free sweetener, and baking soda. This is your dry mix!
Now for the star: take your grated zucchini, wrap it tightly in a clean kitchen towel, and squeeze out all the excess liquid. Discard the liquid.
Add the squeezed zucchini to your dry ingredients, along with the beaten eggs and melted butter. Stir everything gently until just combined – don't overmix!
Pour your delightful batter into the prepared loaf pan (or divide evenly among 12 muffin cups).
Bake in the preheated oven for 45-60 minutes for bread, or 18-20 minutes for muffins, until a toothpick inserted into the center comes out clean.
Let it cool completely before slicing and enjoying!
