1-Preheat oven and prepare pan: Preheat oven to 350°F (175°C). Grease and flour an 8.5×4.5 inch loaf pan, set aside.

2-Mix dry ingredients: In a medium bowl, whisk together 1 1/2 cups all-purpose flour, 1 1/2 tsp baking powder, and 1/4 tsp salt.

3-Combine wet ingredients: In a large bowl, whisk together 1 cup full-fat Greek yogurt, 1 cup granulated sugar, 3 room-temperature eggs, zest of 2 oranges, 1/4 cup fresh orange juice, and 1 tsp vanilla extract.

4-Incorporate oil and dry ingredients: Pour in 1/3 cup olive oil, stir to combine, then gradually fold dry ingredients into wet mixture with a spatula until just combined, leaving a few lumps.

5-Bake: Transfer batter to prepared pan, smooth top, and bake 50-55 minutes until a toothpick comes out clean or with moist crumbs; check at 50 minutes to avoid overbaking.

6-Cool and optionally syrup: Let cake cool in pan 20 minutes, then turn onto a wire rack to cool completely. If desired, brush warm cake with a mixture of 2 tbsp orange juice and 1 tbsp sugar heated until dissolved.

7-Prepare optional glaze: Whisk 1 cup powdered sugar with 2-3 tbsp fresh orange juice until smooth and drizzling consistency; pour over cooled cake and let set before slicing.
