How to Make Instant Oatmeal Cookie

  1. Preheat your oven to 350°F (175°C). Lightly grease a large baking sheet or pizza pan.
  2. In a large bowl, combine the instant oatmeal, brown sugar, butter, egg, vanilla extract, and chocolate chips (or your favorite mix-ins!). Mix until well combined.
  3. Spread the mixture evenly onto the prepared baking sheet to form a large, thick cookie.
  4. Bake for 8-10 minutes, or until the edges are golden brown and the center is slightly soft. Keep a close eye on it as ovens vary!
  5. Let the cookie cool on the baking sheet for a few minutes before slicing and serving. Enjoy warm!
