Line a deep 8 x 8 baking tray or pan with baking paper and set aside. In a large mixing bowl, combine your rolled oats, ground oats, protein powder, cinnamon and sea salt and mix well. In a small microwave safe bowl or stovetop, melt your nut butter with brown rice syrup. Pour your wet mixture in with the dry mixture and mix very well. Allow to cool slightly, before stirring through the chocolate chips. If batter is too crumbly, slowly add milk of choice until a very thick batter is formed. Transfer mixture to lined baking tray and using your hands, press firmly to set. Top with chocolate buttons/m & m's and refrigerate for at least an hour to firm up. Remove and slice into bars.
