Preheat the oven to 350 degrees and grease a muffin pan.
In a small bowl, whisk together the flour, baking powder, and salt.
In a large bowl, mix together the eggs, coconut sugar, ricotta, milk, butter, lemon juice, lemon zest, and vanilla extract.
Add the dry ingredients to the wet ingredients and stir until just combined.
Transfer the batter to the prepared muffin pan. Bake the muffins for 18 minutes, or until a toothpick inserted into the center of a muffin comes out clean. Don’t bake them too long or they’ll be dry.
