Preheat the oven to 350°F (175°C) and line a baking sheet with parchment paper.
In a large bowl, cream together the softened butter and granulated sugar until light and fluffy.
Add the egg and vanilla extract, and mix until combined.
In a separate bowl, whisk together the flour, salt, and baking powder. Gradually add the dry ingredients to the wet ingredients and mix until a soft dough forms.
Chill the dough in the refrigerator for 30 minutes to make it easier to handle.
Once chilled, roll the dough into 1-inch balls and place them on the prepared baking sheet about 2 inches apart.
Use your thumb to create an indentation in the center of each cookie.
In a small bowl, beat together the cream cheese, powdered sugar, and vanilla extract until smooth.
Spoon a small amount of the cream cheese mixture into each cookie's indentation.
Carefully add a small dollop of raspberry jam on top of the cheesecake filling.
Bake for 12-15 minutes, or until the edges of the cookies are lightly golden.
Allow the cookies to cool on a wire rack before serving.
