What you will need
This recipe uses 4 simple ingredients that you can find at any grocery store:
- 2 scoops vanilla ice cream
- 12 oz cold root beer
- 1 tbsp whipped cream
- 1 unit maraschino cherry
Step by step instructions
Step 1: Chill Your Glass
Place a tall soda glass or mug in the freezer for 10 minutes before assembling. A frosty glass keeps the float colder longer and adds to the classic diner presentation.
Step 2: Add Ice Cream
Place two generous scoops of vanilla ice cream into the chilled glass. Allow the ice cream to sit for about 30 seconds to slightly soften so the root beer can work into it.
Step 3: Pour and Garnish
Slowly pour cold root beer over the ice cream. Pour down the side of the glass to minimize foam overflow. Top with a swirl of whipped cream and a maraschino cherry. Serve with a straw and a long spoon.
Easy substitutions
Missing an ingredient? Here are some swaps that work perfectly:
- vanilla ice cream → vanilla frozen yogurt for a lighter version with less fat
- root beer → diet root beer for a lower sugar alternative
Common mistakes to avoid
Watch out for these pitfalls that can affect your results:
- Pouring root beer too fast which causes excessive foaming and overflow
- Using warm root beer instead of cold which melts the ice cream too quickly and reduces fizz
