In a large bowl, beat the butter and sugar together until light and fluffy.

Add eggs and vanilla extract, beating until smooth.

In another bowl, whisk together flour, baking soda, baking powder, and salt.

Gradually add the dry mixture to the wet mixture, mixing until combined.

Chill dough for at least 1 hour (or up to overnight).

Shape the Cookies

Preheat oven to 375°F (190°C).

Roll dough into 1-inch balls. Roll each ball lightly in sugar.

Place on a parchment-lined baking sheet, about 2 inches apart.

Gently press a single raisin into the center of each cookie ball before baking.

Bake for 8–10 minutes, until edges are lightly golden but centers are soft.

Let cool on the pan for 2 minutes before transferring to a wire rack.
