Preheat your oven to 325°F (163°C) and grease a 9x5 loaf pan with butter or line it with parchment paper.

In a large mixing bowl, combine almond flour, baking powder, and salt. Whisk until well blended.

In another bowl, whisk together eggs, granulated sweetener, yogurt, lemon juice, and lemon zest until smooth.

Slowly pour the wet mixture into the dry ingredients and gently stir with a spatula until just combined.

Pour the batter into the prepared loaf pan and smooth the top. Optionally, sprinkle extra lemon zest on top.

Bake for about 50 minutes or until a toothpick comes out clean and the top is golden brown.

Cool in the pan for 10-15 minutes, then invert onto a wire rack to cool completely.

Once cool, slice and optionally frost with a sugar-free glaze. Serve with yogurt or enjoy plain.
