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

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

Beat in the egg and vanilla extract until well combined.

In a separate bowl, whisk together the all-purpose flour and baking powder.

Gradually fold the dry ingredients into the wet mixture until just combined.

Roll small amounts of dough into balls and place them on the lined baking sheet, leaving space between each one.

Using your thumb or the back of a spoon, create a well in the center of each dough ball.

Spoon a small amount of raspberry jam into each well without overfilling.

Bake in the preheated oven for 10 to 12 minutes or until the edges are barely golden.

Let them cool completely on a wire rack before dusting with powdered sugar.
