Preheat your oven to 175°C (350°F). Grease and line a small loaf pan or round cake tin with parchment paper.
In a mixing bowl, whisk together the eggs and erythritol (or honey) until smooth and slightly frothy.
Add in the melted coconut oil, yogurt, and lemon zest. Mix well.
Fold in the desiccated coconut, almond flour, baking powder, and salt. Stir until a thick, smooth batter forms.
Pour the batter into the prepared baking dish and smooth the top.
Bake for 30–35 minutes or until the top is golden and a toothpick inserted into the center comes out clean.
Let the cake cool in the pan for 10 minutes, then transfer to a wire rack to cool completely before slicing.
