1. 1
   Melt the butter in a medium saucepan. Once melted, whisk in the brown sugar. Bring to a boil over high heat and cook 1 minute. Remove from the heat and transfer to a bowl. Whisk in the vanilla. Add the oats, flour, and salt mixing until combined. Let cool 5 minutes, then stir in the egg white. Let the dough sit 10 minutes to thicken.
2. 2
   Position racks in the upper and lower thirds of the oven. Preheat the oven to 350 degrees F. Line 2 baking sheets with parchment paper.
3. 3
   Drop 1 teaspoons size amounts of dough on prepared baking sheet, placing each 3 inches apart. Bake for 7-9 minutes until golden brown around the edges. The butter will be bubbling up around the cookies, this is OK. Allow the cookies to cool on the baking sheet for 5 minutes, then transfer to a wire rack to cook completely.

   Sandwich each cookie with nutella or melted milk chocolate. Store cookies in an airtight container for up to 4 days.
