- You can use other variations of oatmeal, just make sure it is prepared ahead of time before you add it into the recipe.

Do you make the oats into oatmeal before adding it to the ingredients? In your tips section you mentioned it should be prepared before adding but in the recipe there isn’t a step for preparing the oatmeal. Can’t wait to try.
