Preheat the oven to (350°F) = (176°C) degrees. Cream the butter, brown sugar, eggs, and vanilla. Stir in the flour, oats, baking soda, baking powder, and sea salt until blended. Stir in the different chocolate chips or M & M's until blended. Use a cookie scoop to place the dough on a greased cookie sheet or parchment paper placed on the cookie sheet. Place the cookies about 2-inches apart and bake for about 12-14 minutes. These make a very soft, moist, and chewy cookie.
