Step 1 Place all of the ingredients in a slow cooker or an Instant Pot and set to low heat for 2 hours (slow cooking mode on the Instant Pot). If it’s too thick add a bit more milk and stir. (Tip: If you're short on time, simply use the Saute function and cook intil melted for a few minutes. Stir to ensure even cooking. Based on feedback, this is a better method for smoother results.)
