In a large mixing bowl, cream the softened butter and granulated sugar together until light and fluffy.

Mix in the egg and vanilla extract until fully combined.

In a separate bowl, whisk together the flour, baking powder, and salt. Gradually add this mixture into the wet ingredients, stirring until a soft dough forms.

If desired, tint portions of the dough with pastel food coloring.

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

Roll the dough into small balls and place them on the prepared sheets. Lightly flatten each cookie and press an indentation in the center.

Bake for 10-12 minutes until edges are lightly golden and centers remain soft.

Remove cookies from the oven and immediately press a pastel chocolate candy into the center of each cookie.

Allow cookies to cool completely before transferring them to a wire rack or storing.
