Favorite Apple Galette

Instructions

• Make pastry: Whisk flour, white sugar, and salt together in a bowl. Press butter pieces into flour mixture with your fingers until mixture resembles coarse crumbs.
• Make a well in the center of flour mixture. Pour water and vanilla into the well; quickly work water and vanilla into flour to create a loose dough, adding more water if dough is crumbly. You should be able to squeeze it in your hand and have it stay together but be a bit crumbly. Shape dough into a flat disc, wrap in plastic, and refrigerate for at least 30 minutes.
• Make filling: Stir brown sugar, flour, and cinnamon together in a bowl. Add apples and toss to coat. Let sit for flavors to blend, about 10 minutes.
• Preheat the oven to 450 degrees F (230 degrees C).
• Roll dough into a large, rough circle on a baking stone or sheet. Pour apple mixture into the center of dough, leaving a 2-inch uncovered border. Dot apples with 1 tablespoon butter.
• Fold edges of dough up over apples, leaving an opening in the center. Dot dough with remaining 1 tablespoon butter and sprinkle coarse sugar over dough.
• Bake in the preheated oven until crust is crisp and golden and apples are tender and caramelized, 40 to 45 minutes.
