Harry Potter Butter Beer Recipe:
1- 2 liter bottle cream soda
1-7 oz. marshmallow cream
Mix 2 tablespoons butter extract and 2 teaspoons rum extract into the cream soda. Return the cap and gently rotate back and forth to mix.
In a bowl mix 7 oz. marshmallow cream, 1 cup whipping cream, and 1 teaspoon rum extract with a mixer on low speed until thick and foamy.
Pour a glass of cream soda and spoon the "foam" on top.
I hope your kiddos love it as much as my boys do. My little muggle loved our butter beer night.
