Harry Potter's butterbeer fudge is packed full of butterscotch chips and rum flavoring. It has a crumbly texture, just how I like it! Harry Potter fans will love for you making this.
Prepare an 8x8 pan by lining it with tin foil and spraying with non-stick cooking spray.
In a saucepan, add in the butter, half and half, marshmallow cream, granulated and brown sugars. Stir to combine. Place over medium heat and stir constantly.
Once the mixture comes up to a boil. let boil for 5 minutes. Don't mistaken the air pockets from mixing for boiling.
Once the mixture has boiled for 5 minutes, remove from the heat and add in the extracts and butterscotch chips. Mix until the chips are completely melted.
Pour into the prepared pan and give it a few taps to smooth the top.
Place in the fridge and let chill. Cut and serve.
Notes
For a softer fudge, add the marshmallow cream after the mixture has boiled for 5 minutes. Half and half is equal parts whole milk and light cream. It's also known as half cream in the United Kingdom.
