How To Make A High Protein Root Beer Float Recipe

The nostalgic flavors of a classic root beer float are hard to beat. There’s just something about creamy vanilla ice cream swirling into bold, earthy-sweet root beer that brings you right back. But what if you could enjoy that same classic treat with a boost of protein, and even fiber, while still keeping it fun?

This protein root beer float has all the flavor you love, with extra nutrition to keep you satisfied. Each sip delivers that frothy, creamy goodness while helping you hit your protein goals. And if you’re in the mood for a grown-up twist, I’ll also share how to turn this into an adult root beer float for the perfect summer night treat.

    This float takes a nostalgic classic and gives it a nutritious upgrade. It’s creamy, satisfying, and delivers a solid protein boost—without sacrificing that indulgent soda-fountain feel.

  2. Perfect for Post-Workout or Sweet Snack Cravings
    It’s a fun way to rehydrate and refuel after a workout, or to enjoy a sweet treat that actually supports your goals. Light, refreshing, and balanced.

  3. Totally Customizable

Instructions

Make the Protein Ice Cream

  1. Blend the Base
    In a Creami pint container, combine Fairlife milk and vanilla pudding mix. Use a milk frother to blend until smooth and well combined.

  2. Freeze
    Freeze the container for at least 24 hours until solid.

  3. Spin the Ice Cream
    Remove from freezer and let sit for a few minutes if too hard. Place in the Ninja Creami and use the Lite Ice Cream function.

  4. Add Half-and-Half
    After the first spin, add 2 tablespoons of half-and-half to the pint and re-spin. Repeat once if needed for a creamier texture.

Assemble the Root Beer Float

  1. Prep the Glass
    Slowly pour 1 cup of root beer into a tall glass, leaving room for the ice cream. Go slow to prevent overflow.

  2. Add the Ice Cream
    Add 2-3 scoops of vanilla ice cream from your freshly spun protein ice cream to the bottom of the glass. Then pour 1 cup of root beer. Let it foam naturally.

  3. Serve & Enjoy
    Enjoy as-is for a classic float feel, or give it a gentle stir if you prefer it blended. To the top of the glass add whipped cream, a single maraschino cherry, or a drizzle of chocolate sauce if desired.

Make It an Adult Root Beer Float

Want to turn your float into a fun, grown-up treat? You’ve got two great options:

Add a splash of vanilla vodka for a spiked soda-shop feel. It’s simple, smooth, and keeps the root beer vibe going strong.

Or swap the soda for stout beer, my personal favorite is Guinness. Back when I was waitressing, my shift drink was always a Guinness float. There’s something about the way that rich, malty beer blends with creamy vanilla ice cream that’s just unbeatable. It’s basically dessert and happy hour in one glass.

Either way, the protein ice cream still holds its own, giving you a treat that feels indulgent and satisfying. Perfect for backyard BBQs, warm summer nights, or anytime you want something nostalgic with a grown-up twist.

More Variations and Customizations

This float is easy to make your own. Try using different root beer brands for subtle flavor shifts, or swap in a flavored soda like orange or cherry for something totally new. Fiber Coke is a great alternative if you’re looking to add a little extra fiber and support gut health. You can also change up the ice cream, vanilla, caramel, or chocolate protein ice cream all bring their own unique spin and pair deliciously with fizzy soda.

When to Enjoy This Recipe

This protein root beer float is perfect on a hot summer day when you want something cold, creamy, and refreshing. It’s a fun twist on a classic drink that’s great for summer parties, serve it in tall glasses and let everyone customize their own with toppings or different sodas.

Want to take it up a notch? Turn it into a hard root beer float by swapping the soda for a chilled stout or hard root beer. It makes for a rich, grown-up version that’s great for backyard hangouts or casual get-togethers.

Best Tips for the Best Protein Root Beer Float

Want to make your float even better? Try these hacks.

  • Pour the soda slowly at an angle to keep it from foaming over.

  • For extra bubbles, add the ice cream first and pour the soda on top.

  • Use a chilled glass to keep everything cold and refreshing.

  • A straw and spoon combo makes it easier (and more fun) to enjoy. I love scooping up chunks of ice cream along with that fizzy root beer float.

  • Important: If your protein ice cream is crumbly after the first spin, don’t worry! Just add a splash of liquid (half and Half, cream, or whole milk) and run a re-spin, sometimes twice, for a smooth, creamy texture.
