Brew your coffee. Or open your cold brew like the modern sophisticate you are. Then add the vanilla, half and half and sugar. Combine until the sugar desolves. Let it chill—because a warm soda is just…wrong.
Scoop that ice cream into a tall glass. Be generous. Ann Beddingfield would approve.
Good stuff coming in. Time to add the coffee. Fill each cup about half way up. Pour it gently over the ice cream so it’s even prettier.
Fizz it up! Slowly pour the club soda on top and watch the magical foamy head rise. (Resist the urge to stick your finger in it like a 5-year-old. Or don’t. This is a judgment-free zone.)
Crown it with whipped cream and a little chocolate garnish because why not lean all the way in?
Drink two. It’s what Anne did. It’s what Ivy insisted. It’s the law now.
