Fluffy orange cake

Directions

• Preheat the oven to 180°C. 
  Unite a round shape with butter and wheat flour.
• In a large bowl, beat eggs and sugar until fluffy and pale.
• Add the oil, orange juice and orange zest to the egg and sugar mixture. 
  Stir well to combine the ingredients.
• Add the sifted wheat flour to the cake batter, little by little, mixing gently until smooth. 
  Do not overmix to prevent the cake from becoming heavy.
• Add the baking powder and gently mix until incorporated into the dough.
• Pour the dough into the prepared mold and level the surface with a spatula.
• Place in the preheated oven and bake for about 35 to 40 minutes, or until a toothpick inserted in the center of the cake comes out clean.
• While the cake bakes, prepare the syrup (optional): in a small saucepan, combine the orange juice and sugar. 
  Place over medium heat and simmer for about 5 minutes, until the syrup has reduced slightly and thickened slightly.
• Remove the cake from the oven and let it cool in the pan for a few minutes. 
  Then unmold the cake and place it on a serving plate.
• If desired, drizzle the still warm cake with the orange syrup to give it an extra touch of flavor and moisture.
• Let the cake cool completely before serving. 
  You can decorate it with powdered sugar or thin slices of orange.
