Preheat the oven to 400 degrees. Line a baking sheet with parchment paper.
Allow the puff pastry to defrost and come to room temperature.
On a well-floured surface, roll the puff pastry out into a 12 inch by 16 inch piece.
Cut into 12 squares, each 4 inches by 4 inches.
On each square, place a tablespoon of goat cheese.
Then add a teaspoon of wild blueberry jam.
Bring the 2 opposite corners of the puff pastry together, and fold together along the edges. Repeat.
The finished Danish will look like square with a cross.
Bake until the Danish are golden, about 20 minutes.
