Combine all dry ingredients. Add the vanilla to the cold water. Add cold water to dry mixture and knead with hand until dough becomes sticky.
Collect the dough and lightly form a ball. Cover in plastic wrap and let cool in the fridge for 20 minutes or more.
Unroll the pie crusts, place on a lightly floured work surface, and roll the crusts slightly with a rolling pin to square the edges. Cut each crust into 8 equal-sized rectangles. Place about 2 teaspoons of strawberry jam in the center of 8 squares, and spread the jam out to within 1/4 inch of the edge of the pastry square. Top each with another pastry square, and use a fork to crimp the squares together, sealing in the jam. Use a knife to trim the pastries, if desired. Move the filled pastries to the prepared baking sheets.
Bake in oven for 15 minutes.
Mix all ingredients together and cover pop tarts.
Eat and Enjoy-to the glory of God! (1 Corinthians 10:31)
