Mix together cold butter, cream cheese, and vanilla extract in a stand mixer until creamy. Slowly add in the flour until well blended. Let the dough chill in the refrigerator for about one hour.

Preheat your oven to 375 degrees Fahrenheit. Line a baking sheet with parchment paper or lightly greasing it. On a lightly floured surface, roll out the dough until it is about 1/8 inch thick. Slice the dough into squares using a pastry cutter.

Place a small amount of the fruit filling in the center of each square. Fold the corners of the square over the filling to meet in the middle, slightly overlapping them.

Place a bit more filling between the overlapping corners to secure the cookies during baking.

Arrange the cookies on the prepared baking sheet and bake for 12-15 minutes. Check halfway through and gently press any opened corners back into place. Transfer to a cooling rack once finished.

Once cooled, sprinkle the cookies with powdered sugar for a sweet finish.
