1. Preparation of ingredients:

Take the butter out in advance so that it is at room temperature or melt it gently, then let it cool.
If you choose lemon, wash and finely grate the zest. Set aside.
Prepare a 23 to 24 cm diameter tart pan and line it with baking paper.
2. Creation of the device:
In a large bowl, start by beating together the eggs and powdered sugar. Use an electric whisk or hand mixer until the mixture becomes light and fluffy, which usually takes 3 to 5 minutes.
Gradually add the flour to the egg-sugar mixture, continuing to mix to avoid lumps forming.
Then pour the cooled melted butter into the mixture and mix gently until you obtain a smooth texture.
3. Adding flavors and yogurt:
Depending on your preference, add vanilla extract or grated lemon zest to the dough to pleasantly flavor your pie.
Add the plain yogurt and mix gently until the mixture is smooth and the yogurt is completely incorporated.
4. Cooking:
Preheat your oven to 180°C (static mode).
Pour the mixture into the prepared mold.
Bake for 25 to 30 minutes. The tart should be golden and firm to the touch.
Once out of the oven, let the tart cool in its pan on a rack. It will continue to firm up as it cools.
5. Demolding and finishing:
Once cooled, carefully unmold the tart.
Just before serving, sprinkle with icing sugar for a delicious and aesthetic final touch.
