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

Cream together the unsalted butter and granulated sugar until light and fluffy.

Add eggs one at a time along with the vanilla extract, mixing until well combined.

In another bowl, whisk together the flour, baking powder, and salt. Gradually fold into the wet ingredients until just combined.

Scoop tablespoon-sized portions of dough and roll into balls. Place on prepared baking sheets with space in between.

Create an indentation in each cookie ball using your finger or the end of a spoon, then fill with jam.

Bake for 12-15 minutes or until golden brown. Allow to cool slightly before transferring to a wire rack.
