A fizzy root beer float with creamy vanilla ice cream is a nostalgic, family-favorite American treat. This classic soda fountain combination is pure simple pleasure.
Place two tall glasses in the freezer for at least 10 minutes before assembling to keep the float extra cold.
Scoop 3/4 cup of vanilla ice cream into each chilled glass, packing it gently at the bottom for a solid base.
Slowly pour 1 cup of chilled root beer over the ice cream in each glass, tilting the glass slightly to minimize excessive foaming.
Wait about 30 seconds to allow the foam to settle, then top off with extra root beer as needed, up to the rim.
Optional: Finish with 1 tablespoon of whipped cream and a maraschino cherry on top for classic presentation. Serve immediately with both a straw and a long spoon.
