Preheat oven to 325℉. Line an 9x5 inch loaf pan with parchment paper.
In a large bowl, whisk together the eggs, yogurt, vanilla, lemon zest and lemon juice until combined. Next, add in the almond flour, sugar, baking powder, salt and mix until incorporated. Then, transfer the mixture to the loaf pan and spread out evenly. Bake for 50-55 minutes or until toothpick comes out clean. Let it set in the pan for 10 minutes. Transfer to a wire rack to allow to cool completely.
