Place the orange in a blender, add the olive oil and Greek yogurts, and blend on high for about 3 minutes until smooth. Strain the mixture to remove any solids.

In a separate bowl, beat the eggs and mix with the sugar. Add the blended orange mixture to this bowl.

Add the flour and baking powder all at once, then beat well for a few minutes until the batter is smooth and free of lumps. Grease and flour the cake pan before pouring in the batter to prevent sticking and make it easier to remove later.

Stir in the chocolate chips and mix to distribute them evenly throughout the batter. Bake at 350°F (180°C) for 50-60 minutes. If the top browns too quickly before the cake is done, cover it with aluminum foil until fully baked.
