Preparation Steps

• To the bowl of a stand mixer fitted with the paddle attachment (or large mixing bowl and electric mixer) add the egg, butter, sugars, vanilla, and beat on medium-high speed until creamed and well combined, about 4 minutes.
• Stop, scrape down the sides of the bowl, and add the flour, oats, baking soda, salt, and beat on low speed until just combined, about 1 minute.
• Stop, scrape down the sides of the bowl, and add the chocolate chips, Cornflakes, coconut, pecans, and beat on low speed until just combined, about 1 minute.
• Using a large cookie scoop, 0.25-cup measure, or your hands, form approximately 13 equal-sized mounds of dough.
• Place mounds on a large plate or tray, cover with plastic wrap, and refrigerate for at least 2 hours, up to 5 days. Do not bake with unchilled dough because cookies will bake thinner, flatter, and be more prone to spreading.
• Preheat oven to 350°F, line a baking sheet with a Silpat or spray with cooking spray. Place dough mounds on baking sheet, spaced at least 2 inches apart (I bake 8 cookies per sheet) and bake for about 10 to 12 minutes (11 minutes in my oven is just right), or until edges have set and tops are just set, even if slightly undercooked, pale, and glossy in the center; don’t overbake. Cookies firm up as they cool.
• Allow cookies to cool on baking sheet for about 10 minutes before serving. I let them cool on the baking sheet and don’t use a rack.
