Cinnamon Apple Galette with Oat Crust and Brown Sugar Ice Cream

Ingredients

In a medium bowl, whisk together oats, brown sugar, and salt.
Add cold butter and use a pastry blender or your fingers to work it into the dry ingredients until mixture resembles coarse crumbs.

Preheat oven to 375°F (190°C).
In a large bowl, combine sliced apples, granulated sugar, cinnamon, nutmeg, and salt. Mix well to coat.
On a lightly floured surface, roll out oat crust to a thickness of about 1/8 inch.
Transfer apple mixture to the center of the dough, leaving a 2-inch border around it.
Fold edges of the dough up over the filling, pressing gently to seal.
Brush beaten egg over the crust and sprinkle with additional brown sugar if desired.
Bake for 40-45 minutes or until crust is golden brown.

In a medium saucepan, combine 1 cup heavy cream, 1/2 cup granulated sugar, and 1 tsp vanilla extract. Bring to a simmer over medium heat.
Reduce heat to low and cook for an additional 5-7 minutes or until mixture is reduced slightly and syrupy.
Remove from heat and stir in 1/4 cup brown sugar until dissolved.
Allow mixture to cool completely before churning in an ice cream maker according to manufacturer's instructions.
