Once the dough has doubled in size, divide it into 12 equal pieces.
Shape them into balls, cover with a clean kitchen towel, and let them rest for 15 minutes.
Preheat the oven to 390°F 200°C. Line two large baking sheets with parchment paper.
For boat-shaped fatayer, take one dough ball and roll it into a small oval, about 6 inches(15 cm) long.
Place 1 ½ tablespoons of filling in the center, leaving a small border around the edges.
Fold the long left side of the dough slightly over the filling, then fold the long right side over in the same way. Leave the middle of the filling visible.
Pinch both ends firmly to seal and create a boat shape.
Place the shaped fatayer on the prepared baking sheet. Repeat with the remaining dough balls and filling.
For triangle fatayer, take one dough ball and roll it into a thin circle, about 6 inches (15 cm) wide. Place 1 ½ tablespoons of filling in the center.
Lift the left and right sides of the dough and bring them together above the filling.
Pinch the two sides together from the top down toward the center, leaving the bottom side open.
Lift the bottom side of the dough up toward the center to form a triangle. Pinch all three seams firmly to seal the filling inside. Make sure the corners are closed well so the filling does not leak while baking.
Place the triangle fatayer on the prepared baking sheet, seam side up. Repeat with the remaining dough balls and filling.
