Freezing the dough for at least 10 minutes is crucial to keep the single serve oatmeal cookie from spreading. This step also helps make the cookie more flavorful!

You can make different variations of this single serving oatmeal cookie! Instead of chocolate chips, you can use chopped walnuts or raisins.
