What Is a Root Beer Float?

A Root Beer Float (sometimes called a black cow) is a classic soda fountain drink made by adding scoops of vanilla ice cream to a cold glass of root beer. The carbonation reacts with the ice cream, creating a creamy foam that makes the drink extra delicious.

This sweet and fizzy treat became popular in the United States in the late 1800s and has remained a favorite ever since.

How to Make a Frosty Root Beer Float

Step 1: Chill the Glass

Place your serving glass in the freezer for about 5–10 minutes. A chilled glass keeps the float colder longer.

Step 2: Add the Root Beer

Pour the cold root beer slowly into the glass until it’s about two-thirds full.

Step 3: Add the Ice Cream

Gently add 2–3 scoops of vanilla ice cream into the root beer. The soda will fizz and create that classic creamy foam.

Step 4: Add Toppings

Top with whipped cream and a maraschino cherry if desired.

Step 5: Serve Immediately

Serve with a straw and spoon for the perfect soda fountain experience.

Tips for the Best Root Beer Float

Use extra cold root beer for maximum fizz.
Pour the soda slowly to prevent overflow.
Use high-quality vanilla ice cream for the creamiest flavor.
For thicker floats, add more ice cream.

Fun Root Beer Float Variations

Chocolate Root Beer Float

Add a drizzle of chocolate syrup before adding the ice cream.

Caramel Float

Top the float with caramel sauce and whipped cream.

Creamy Root Beer Float

Use vanilla bean ice cream for richer flavor.

Adult Root Beer Float

Add a splash of vanilla vodka or bourbon for a grown-up version.

What to Serve with Root Beer Floats

Root beer floats pair perfectly with classic comfort foods like:

Burgers
Hot dogs
French fries
Pizza
BBQ sandwiches

They’re also great with cookies or brownies for a fun dessert combo.

Storage Tips

Root beer floats are best served immediately. Because of the carbonation and melting ice cream, they don’t store well and should be enjoyed fresh.
