Preheat your oven to 180°C (356°F).

In a mixing bowl, add a pinch of salt, 8g of vanilla sugar, and 90g of fine sugar.

Add 2 eggs to the mixture and mix well until combined.

Gradually add 90ml of oil, continuing to mix until well incorporated.

Add 100g of cornstarch and mix until smooth.

Gradually add about 300g of flour in batches, mixing well after each addition, until a soft dough forms.

Shape the dough into small balls or your desired shapes.

Place the shaped dough onto a baking sheet lined with parchment paper.

Bake in the preheated oven at 180°C (356°F) for about 25 minutes, or until the biscuits are lightly golden.

If desired, once the biscuits are cooled, spread some strawberry jam on one biscuit and top it with another to make a sandwich.

Enjoy your delicious homemade biscuits!
