Ceylon Cinnamon And Apple Galette With Vanilla Sugar

["1. Preheat oven to 350u00b0F and move racks so that they are in the middle of oven.", "2. Roll out the pie dough on a lightly floured surface so that it is about 12"" in diameter by 1/4"" thick. To make a neater edge, trim it so that the pie dough is a perfect circle.", "3. Line a sheet pan with parchment or Silpat mats and gently place your pie dough onto it. Set aside.", "4. Core, then thinly slice your apples. I left the skins on but feel free to peel if you're opposed to skin. Place apple slices into a bowl and toss with the remaining ingredients.", "5. Carefully place all of your apple filling into the center of your pie dough leaving a border around the edge.", "6. Next, carefully fold up the sides of the dough (up and over the apples but leaving some of the center apples exposed), gently pressing where the dough touches itself. Be cautious not to let the apples poke through the folded over dough. If this does happen, simply press the dough hole closed with your fingers.", "Optional: You can definitely make a quick egg wash by combining the egg and water in a small bowl. Then brush it over the top of the galette crust. Or you can lightly brush the top with heavy cream to get the same effect. I opted not to do that. Keep in mind that if you do, your galette will brown faster than without, so keep an eye on it.", "Also optional, you can sprinkle the top of your dough with some additional vanilla sugar. If your dough is completely thawed out, your sugar should stick right to it, without the help of anything. I chose that route.", "7. Bake at 350u00b0F for about 45 minutes, rotating the pan halfway through. You're looking for tender apples and a golden brown crust. Again, if you egg/cream washed your crust beforehand, keep an eye out towards the end of the bake time!", "Once cooked, remove it from the oven and allow it to rest on the pan for 10-15 minutes before removing it and placing on a platter or plate. Serve slightly warm or at room temperature with powdered sugar, whipped cream, or vanilla bean ice cream on top!"]
