Preheat the oven to 350°F (175°C). Lightly oil an 8x4-inch loaf pan.
In a large bowl, whisk together the all-purpose flour, almond flour, baking powder, and sea salt.
In a separate large bowl, whisk together the cane sugar and lemon zest until fragrant.
Add the Greek yogurt, olive oil, eggs, and vanilla extract to the sugar mixture. Whisk until smooth and fully combined.
Add the dry ingredients to the wet ingredients and gently stir until just combined. Avoid overmixing.
Pour the batter into the prepared loaf pan and smooth the top.
Bake for 40–50 minutes, or until a toothpick inserted into the center comes out clean.
Allow the Lemon Yogurt Cake to cool completely in the pan before removing.
Prepare the lemon glaze and drizzle it over the cooled cake.
Garnish with extra lemon zest, slice, and serve.
