Grease the loaf pan and line it with parchment paper. You can also just grease and flour it.
Preheat the oven to 180°C (350°F).
Empty the yogurt containers into a mixing bowl and add the sugar.
Whisk the yogurt and sugar together until smooth and homogeneous.
Add the eggs and mix well.
Add the vegetable oil and mix.
Add the sifted flour and baking powder, or sift them directly into the mixture.
Mix until smooth without overmixing.
Pour the batter into the pan and smooth the top.
Bake for 55 minutes to 1 hour 15 minutes, more or less.
Do not open the oven before 45 minutes of baking.
Check the doneness by inserting a toothpick or a paring knife into the middle of the cake.
The tester should come out clean.
Remove the cake from the pan and place it on a wire rack, rounded side up and let it cool before enjoying.
Enjoy and I hope you'll adopt this recipe, which is very simple and gives excellent results.
