Favorite Apple Galette

Make pastry: Whisk flour, white sugar, and salt together in a large bowl until well combined. 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 into flour mixture 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 separate bowl until well combined. Add apples and toss to coat. Let sit until flavors 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 the 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.
