This 10 minute single serving cookie dough is safe to eat raw, because it doesn't have flour in it (oats instead) and is egg-free. It's gluten free, and just as delicious as my favorite one serving chocolate chip cookie.
Add butter, white sugar, and brown sugar to a medium mixing bowl. Cream together with a hand mixer. It will be pebbly, just press together with a spoon/rubber spatula a few times.
Add in ground oats/oat flour. Mix until incorporated. Press together with spoon/rubber spatula. If it holds together, great, if not, add a splash of milk at a time until it does.
