Nutella Stuffed Chocolate Chunk Oatmeal Cookies

In a mixing bowl, combine the melted and cooled butter, sugar, egg, and vanilla. Whisk by hand until uniform, then stir through the flour, oats, sea salt, cinnamon, and baking powder. Once a sticky dough forms, stir in chopped chocolate and make sure it’s mixed through completely. Roll the dough into balls and place each cookie on a greased cookie sheet. Flatten the cookies, then dollop a bit of Nutella into the center of each one. Use your hands to form the dough around the Nutella and cover it completely, rolling back into a ball shape with this in the center. Place back on the sheet, flatten, and repeat for each cookie. Bake for 10-12 minutes at 350F or until golden brown.
