Quick Shortbread Cookies That Melt in Your Mouth

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

In a bowl, cream together the softened butter and powdered sugar until light and fluffy.

Add mayonnaise, vanilla extract, salt, and egg; mix until well combined.

Sift in cornstarch, flour, and baking powder gradually, folding the mixture until a soft dough forms.

Roll small portions of dough into balls and place them on the baking sheet, spacing evenly. Flatten each ball gently with a fork or your palm.

Bake for 12-15 minutes, or until the edges are lightly golden.

Let cool on a wire rack before serving.
