Strawberry Jam Cookies

In a large mixing bowl, cream the butter, sugar, and vanilla sugar until light and fluffy.

Add the oil and egg white, mixing until well combined.

Sift the flour, corn starch, and baking powder together, then gradually add this dry mixture to the butter mixture, mixing until a smooth dough forms.

Shape the Cookies:

Preheat the oven to 350°F (175°C) and line a baking sheet with parchment paper.

Roll the dough into small balls (about 1 inch in diameter) and place them on the prepared baking sheet.

Gently press a small indentation in the center of each dough ball with your finger or the back of a spoon.

Add the Jam:

Spoon a small amount of strawberry jam into each indentation.

Bake:

Bake the cookies in the preheated oven for 12-15 minutes, or until the edges are lightly golden.

Cool and Serve:

Let the cookies cool on the baking sheet for a few minutes before transferring them to a wire rack to cool completely.

Enjoy these melt-in-your-mouth strawberry jam cookies!
