Preheat oven to 165°C (325°F) to ensure optimal baking conditions.
02 -
In a stand mixer fitted with paddle attachment, beat salted butter, white sugar, and baking powder on medium speed until mixture is light and fluffy, about 3 to 4 minutes.
03 -
Scrape down sides of the bowl. Add the egg and beat thoroughly until fully incorporated. Add vanilla extract and mix until combined.
04 -
Gradually add all-purpose flour on low speed, mixing only until just combined to avoid tough dough.
05 -
Roll dough into 2.5-centimetre balls. Place balls at least 2.5 centimetres apart on a baking sheet.
06 -
Using your thumb or a rounded tool, make a central indentation in each dough ball for jam filling.
07 -
Spoon raspberry or apricot jam into each indentation, slightly overfilling to account for spreading during baking.
08 -
Bake in the preheated oven for 20 minutes. Rotate the baking sheet halfway through to ensure even cooking.
