Remove the pie dough from the refrigerator and place onto a lightly floured work surface. Using a rolling pin, roll the dough out to approximately ⅛th of an inch thick. See Note!
Using a chef's knife, cut the dough into 3-inch by 4-inch rectangles. Remove any scraps of dough from the edges and press them together. Wrap them in plastic wrap and place them back into the refrigerator.
Wet your finger in the small bowl of water and wet around the edges of each dough rectangle. See note.
Small Bowl of Water
Then, scoop about 1 tablespoon of jam into the center of half of the dough rectangles. Top them with the remaining dough rectangles and gently press around the edges with your fingers, then using a fork, crimp around the edges to seal them.
½ Cup Strawberry Jam
Transfer the pop tarts to a parchment-lined baking tray and use a sharp knife to slice a small vent into the top layer of pie dough.
Repeat with the remaining pie dough, as well as the scrap from the first rounds of rolling. You will get about 10 pop tarts. Once you are finished, place the baking tray of pop tarts in the refrigerator while the oven preheats.
Preheat the oven to 425* F.
Bake the tartlets for 20-24 minutes or until they are golden around the edges.
