Preheat your oven to 350°F (175°C) and gather your mixing bowls, measuring cups, and a lined baking sheet.

In a large mixing bowl, cream together the softened unsalted butter and granulated sugar for about 3 to 5 minutes until light and fluffy.

Add the eggs one at a time, mixing until well incorporated, then drizzle in the vanilla extract.

Whisk together the all-purpose flour, baking powder, and salt in a separate bowl, then fold into the wet mixture until just combined.

Shape tablespoon-sized amounts of dough into balls and place them on the lined baking sheet, spaced apart.

Make a small well in the center of each cookie ball and spoon ½ teaspoon of jam into each well.

Bake for 12 to 15 minutes until the edges are lightly golden and centers are set, then let cool for 5 minutes on the baking sheet.

Transfer cookies to a wire rack to cool completely.
