In a large mixing bowl, combine the sugar with the orange zest.

Using a spatula, rub the zest with sugar to release the citrus oil.

Add vegetable oil and yogurt to the sugar-zest mixture.

Crack the eggs one by one and stir in vanilla essence.

Pour in the freshly squeezed orange juice and whisk together until combined.

Place a fine mesh strainer over the bowl and add all-purpose flour, baking powder, and salt.

Sift the dry ingredients by gently shaking the strainer until everything passes through.

Using a spatula, gently fold until the batter is smooth and no dry flour remains.

Grease and line a 9x5-inch loaf pan with parchment paper.

Pour the batter into the prepared pan, spreading it evenly.

Bake in a preheated oven at 350 degrees Fahrenheit or 175 degrees Celsius, for 50-55 minutes or until a toothpick inserted into the center comes out clean.

Once baked, remove from the oven and let the cake cool in the pan for 15 minutes.

Transfer the cake to a wire rack and cool completely.

In a small mixing bowl, add powdered sugar and orange zest.

Pour in the freshly squeezed orange juice and whisk until the mixture is smooth.

Pour the orange glaze evenly over the cooled loaf cake and garnish with orange zest.

Let the glaze set, then slice into pieces. Enjoy a delicious creamy orange loaf cake with bright citrus flavor in every bite!
