Preparation Steps

• In a large bowl, beat the cold cubed butter and cream cheese together with the granulated sugar until smooth and creamy.
• Add the egg yolks and vanilla extract and beat until fully incorporated.
• Stir in the flour and salt until a soft dough forms. Do not overmix — the dough should come together but remain tender.
• Shape the dough into a disk, wrap in plastic, and chill in the refrigerator for at least 1 hour.
• Preheat the oven to 375°F (190°C). On a lightly floured surface, roll the chilled dough to about 1/8 inch thickness and cut into 2.5-inch squares or rounds.
• Place a small spoonful (about 1/2 tablespoon) of apricot jam in the center of each square. Fold opposite corners toward the center to form the traditional kolacky shape, leaving the jam visible.
• Arrange the kolacky on a baking sheet lined with parchment paper and bake for 12 to 15 minutes, until the edges are lightly golden.
• Allow cookies to cool on the baking sheet for a few minutes, then transfer to a wire rack. Once cool, dust with powdered sugar before serving.
