Preheat your oven to 350°F (175°C) and prepare an 8-inch round cake pan by lining it with parchment paper or greasing it.

In a large mixing bowl, whisk together the fresh lemon juice, lemon zest, honey or maple syrup, large eggs, plain Greek yogurt, and vanilla extract until smooth.

In a separate bowl, thoroughly mix the almond flour, baking powder, and a pinch of salt.

Gently fold the dry ingredients into the wet mixture using a spatula until just combined.

Pour the batter into the prepared cake pan and smooth the top with a spatula.

Bake for 30–35 minutes, checking for doneness with a toothpick inserted in the center.

Once baked, let the cake cool in the pan for about 10 minutes, then transfer it to a wire rack to cool completely.
