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

In a large bowl, cream together unsalted butter, granulated sugar, and brown sugar until light and fluffy (about 3 minutes).

Mix in vanilla extract until well combined.

In another bowl, whisk together flour, baking powder, and salt. Gradually add this dry mix to the butter mixture until just combined.

Scoop tablespoon-sized portions of dough onto prepared sheets and create an indentation in each cookie for the jam.

Fill each indentation with about half a teaspoon of jam.

Bake for 12-15 minutes until edges are lightly golden. Cool slightly before transferring to wire racks.
