1. Skewer your marshmallows onto wooden sticks or metal skewers—I prefer metal because they’re reusable and easier to control over flame.
2. Toast those marshmallows over an open flame until they’re golden brown and gooey inside. Rotate constantly so they brown evenly. You can use a kitchen torch (my favorite), a gas stove burner, or even broil them in the oven for 1-2 minutes. If they catch fire, blow it out immediately and embrace that extra-toasted campfire flavor.
3. While the marshmallows are toasting, scoop generous portions of vanilla ice cream into tall glasses. Don’t pack it down; just let those scoops sit naturally.
4. Here’s the crucial part—slowly pour root beer over the ice cream in each glass. It’s going to foam up like crazy, so pour slowly and let it settle between pours. Fill about three-quarters full, leaving room at the top for toppings.
5. Drizzle that chocolate syrup over the top in a zigzag pattern—this transforms it from a regular root beer float into something special.
6. Place your still-warm toasted marshmallows on the rim of each glass, letting them lean in slightly so they start melting into the float. If they fall in, that’s fine—they’ll create pockets of melty marshmallow goodness.
7. Serve immediately with a straw and watch the magic happen as the warm marshmallows melt into the cold ice cream!

This is definitely an indulgent treat—high in sugar from the soda, marshmallows, and chocolate syrup. The ice cream provides some calcium, but let’s be real, you’re drinking this for pure dessert nostalgia and those toasted marshmallow vibes.

Notes:

• Toast marshmallows until golden brown—don’t just warm them
• Rotate constantly while toasting to prevent burning
• Pour root beer slowly to prevent overflow
• Use really cold root beer and properly frozen ice cream
• Work quickly so marshmallows are still warm when you add them
• Every brand of root beer foams differently, so adjust pour speed

Storage Tips:

• Don’t try to store this—it’s best made and served immediately
• The fizz goes flat and ice cream melts fast
• Toast marshmallows fresh each time for best flavor
• Takes 7 minutes total, so just make fresh when ready

What Makes This Recipe Special:

This recipe follows classic ice cream float principles—combining creamy ice cream with fizzy soda to create that magical foaming reaction beloved since the 1870s. What sets this toasted marshmallow float apart from traditional root beer floats is the genius addition of campfire-toasted marshmallows that add smoky sweetness and nostalgic s’mores flavor, plus the chocolate drizzle that bridges the flavor gap between root beer float and s’mores. The technique of adding warm, freshly-toasted marshmallows to cold ice cream and fizzy soda creates multiple temperature and texture contrasts in one glass—hot and cold, creamy and fizzy, gooey and smooth—proving that the best desserts often come from combining familiar childhood favorites in unexpected, delicious ways.
