Cream Butter & Sugar:
Beat softened butter and sugar until pale and creamy.

Add Egg & Vanilla:
Mix in the egg and vanilla extract until smooth.

Combine Dry Ingredients:
Whisk together flour, baking powder, and salt. Gradually add to wet ingredients until a dough forms.

Chill Dough:
Wrap the dough in plastic wrap and chill for at least 1 hour.

Preheat Oven:
Preheat to 175°C (350°F) and line baking trays with parchment paper.

Shape the Cookies:
Roll out the dough to about ¼ inch thick. Cut into circles using a cookie cutter. On half of the circles, cut small heart shapes in the center.

Assemble & Fill:
Place solid circles on the baking sheet. Spoon a small amount of jam in the center, then top with the heart-cutout cookies. Press edges gently to seal if needed.

Bake:
Bake for 10–12 minutes or until lightly golden around the edges. Cool on a wire rack.
