Place two generous scoops of vanilla ice cream into a tall glass. Choose a sturdy glass to handle the fizzy reaction later.

Slowly pour 2 oz of RumChata over the ice cream. Let it drizzle over the scoops so the cinnamon-vanilla flavors start soaking in.

Gently pour 1 cup of chilled root beer into the glass. Pour slowly along the side to control the foam — the goal is a fizzy crown, not a volcanic eruption!

If desired, add a swirl of whipped cream on top. Finish with a bright red maraschino cherry for that classic float look.

Serve immediately with a straw and a long spoon. Stir slightly before sipping for the perfect creamy, fizzy blend.

Tip: If the foam overflows too quickly, simply pause pouring for a few seconds to let the bubbles settle.
