Add the flour and chipotle powder, whisking well to combine.
Add the chicken broth, whisking while pouring in the broth to combine.
Allow the gravy to simmer over medium-low heat for 10 minutes to thicken, stirring occasionally.
You can opt to use turkey drippings instead of the chicken stock. If you use the drippings, strain first and allow the drippings to sit until the fat from the drippings rises to the top. Remove the fat with a teaspoon, then use in the recipe.
