Preheat oven to 350°F.

Roll out desired size of dough into a rectangle. Using a sharp knife, cut dough into a diamond shape.

Cut out a small triangle from the center of one of the halves of the diamond.

Place filling directly opposite the triangle, on the other half of the dough.

Fold over to form a triangle/hamantashen shape, and seal edges.

Brush with egg wash.

Bake until golden.
