Preheat oven to 350F and line a 7 or 9 inch springform pan with parchment paper.
In a bowl, use a large fork OR mixer to beat together: sugar or honey, the 4 yolks, vanilla extract, and lemon zest until nice and well-combined.
Whisk together dry ingredients: almond flour, sea salt, baking powder and then add to the yolk, sugar, vanilla and lemon zest mixture.
In a separate bowl, use a mixer to beat the four egg whites until you’ve got nice, foamy peaks.
Gently fold the egg white mixture into the cake batter in three stops.
Transfer batter to a pan and bake at 350F for ~30-35 mins.
