1 pre-made pie dough or homemade pastry dough (enough to make a 10-inch galette)
1 egg, beaten
1 tablespoon maple sugar
All-purpose flour, for dusting
Directions
Set your oven to preheat at 375 F.
In a large skillet over medium heat, combine the maple syrup, dark brown sugar, and vanilla bean paste. Stir gently until the sugar is dissolved and the mixture begins to simmer.
Whisk in the butter, cinnamon, and salt, ensuring the mixture is smooth.
Add the apples to the skillet, ensuring they are well-coated with the syrup mixture. Cook for about 10 minutes or until they just begin to soften. The liquid should reduce to a glossy, thick consistency.
On a floured surface, roll out your dough into a circle approximately 12 inches in diameter. Transfer the dough onto a baking sheet lined with parchment paper or a silicone baking mat.
Spread the caramelized apple mixture onto the center of the dough, leaving a 2-inch border all around.
Gently fold the edges of the dough over the apples, pleating as necessary to ensure a snug fit.
Brush the folded edges of the dough with the beaten egg wash. Sprinkle the entire galette, especially the edges, with maple sugar.
Place the galette in the preheated oven and bake for about 25-30 minutes or until the crust is golden and the apple filling is bubbly.
Remove the galette from the oven and let it cool on a wire rack for about 10 minutes.
Slice and serve warm. Serve with a scoop of vanilla ice cream or a dollop of whipped cream, if desired.
