Even though it's not traditional to bake the qatayef, but it's doable. Preheat the oven to 425 degrees F and line a baking sheet with parchment paper. Place the filled and sealed pancakes on the baking sheet and coat them with cooking spray. Bake for 25 minutes, flipping them once midway, until they are golden and crispy. Then toss them in the simple syrup.
