Creamy 5-Minute Keto Cola Float (No Ice Cream!)

Dessert, Dips & Sauces

March 9, 2026

There’s nothing quite like the memory of a fizzy, frosty soda float on a hot day. In the South, while root beer has its place, the Coca-Cola float reigns supreme! It’s that perfect marriage of spicy cola and sweet, creamy vanilla ice cream. I wanted to capture that nostalgic magic in a glass, but without the sugar and carbs. This brilliant dupe uses heavy cream to mimic the rich flavor of melted ice cream, creating a surprisingly decadent and utterly delicious sugar-free cola float. It’s the 5-minute treat you didn’t know you were missing!

Ingredients

• 1 cup / 140g crushed ice
• 2 tablespoons / 30ml heavy whipping cream
• 12 ounces / 355ml sugar-free cola (or other diet soda)
• Liquid stevia, to taste
• Sugar-free whipped cream, for topping

Instructions

1. Chill your mug. Place a large, 20-ounce mug in the freezer for at least 30 minutes, or until it’s perfectly frosty to the touch.
2. Build your float. Fill the frosty mug with the crushed ice, then pour the heavy cream directly over the ice.
3. Add the fizz. Very slowly and carefully pour the sugar-free cola over the ice and cream. Pouring slowly is key to prevent it from fizzing up and overflowing.
4. Sweeten and serve. Add a few drops of liquid stevia to reach your desired sweetness and give it a gentle stir to combine. Top with a generous swirl of whipped cream and enjoy immediately!
