Preheat the oven to 350°F (175°C).
Lightly grease an 8x4-inch loaf pan with olive oil.
In a large bowl, whisk together the all-purpose flour, almond flour, baking powder, and sea salt.
In a separate bowl, combine the cane sugar and lemon zest.
Rub the zest into the sugar with your fingers to release the lemon oils.
Add the Greek yogurt, olive oil, eggs, and vanilla extract.
Whisk until smooth and fully combined.
Add the dry ingredients to the wet ingredients.
Stir gently until just combined. Avoid overmixing.
Pour the batter into the prepared loaf pan.
Smooth the top with a spatula.
Bake for 40–50 minutes or until a toothpick inserted into the center comes out clean.
Allow the cake to cool completely in the pan before removing.
