Transfer the dough onto a lightly floured surface and begin to roll out the dough into a rectangle or circle until it is about 1/4 in thick. (If the dough is too crumbly, do not be scared to add more water.)
Line a baking sheet with parchment paper. Transfer the crust onto the prepared baking sheet. Brush the dough with 2 tbsp of maple syrup and sprinkle with cinnamon, about 1/4 tsp. Leaving a 1-inch border around the edge, add the sliced fruit to the center of the crust. Pour a tablespoon or two of any extra liquid from the peaches over the fruit.
Fold the edges of the crust over the fruit. Brush the dough with butter and sprinkle with coconut sugar. Then, place the galette in the fridge for 30 minutes to chill. Preheat the oven to 375 degrees F.
Transfer the galette into the oven and bake for 45 minutes, or until golden brown.
Remove the galette from the oven. Brush apricot jam on the crust and filling for a beautiful glossy finish. Let the galette cool for 5 minutes, then top with ice cream if desired. Enjoy!
