Instructions

1. Line 2 baking sheets with parchment and place the oven racks in the upper and lower thirds of your oven. Preheat to 350ºF.
2. In a large bowl whisk together the oats, flour, malt powder, baking powder, baking soda, and salt.
3. In an electric mixer fitted with the paddle attachment, beat together the butter and the sugars until light and fluffy, about 3-4 minutes. Add the eggs one at a time, scraping the bowl after each addition. Reduce the speed to medium low and slowly add the milk and vanilla. Mix until well combined. Reduce speed to low and gradually add the oat mixture until just combined. Using a rubber spatula, fold in the chocolate chips and nuts.
4. Scoop the cookie dough, about 2 tablespoons per cookie, onto the prepared baking sheets, leaving about 2 inches of space between each cookie. Sprinkle each cookie with sea salt. Bake until they are just set and golden around the edges, about 12 minutes (I did about 14 minutes). Let cool on the baking sheet for about 5 minutes and then transfer to wire racks to cool completely. These cookies will keep in an airtight container at room temperature for up to 4 days.
