Step 1

Add all ingredients (except vanilla) to a medium saucepan over medium heat. Whisk to combine. Bring mixture to a low boil (bubble) and whisk constantly until hot fudge thickens, about 5 minutes.

Step 2

Remove from heat, add vanilla, and whisk to combine. Allow hot fudge sauce to cool, then transfer to a resealable glass jar or serve right away.

Step 3

Keep refrigerated and reheat as necessary. Enjoy!
