Preheat oven to 400°F. Line two baking sheets with parchment paper.
Roll out your dough evenly on a floured surface to a thickness of approximately ⅜ inch.
Cut your dough evenly in to your desired shape (for reference, Pop-Tarts™ are about 3 by 5 inches). We made ours in square shapes, but be creative – check out these lovely heart-shaped hand pies!
With a fork, poke holes into half of your shapes (to allow air to escape while baking – or get creative and cut out designs!)
On the shapes that you did not poke holes into, evenly spread your jam beginning in the center. Leave about ¼inch around the edge.
Place a “holey” piece on top of the jam, and use a fork to crimp the edges.
If desired, use an egg wash over the top of your pastry. Whip your egg in a bowl and use a brush to spread it evenly over the top of each pastry (this simply makes the outside “shiny” and does not affect the taste – it is completely optional so leave off for an egg-free/vegan treat).
Carefully place your pastries on the baking sheets, spread evenly.
Bake in a preheated 400°F for 12 to 15 minutes or until golden brown.
Remove from baking sheets and allow to cool (baked jam is HOT).
Serve & Enjoy! Happy Baking!
