Keto-friendly sugar-free cola float is pure soda-fountain nostalgia — sugar-free cola poured over crushed ice and heavy cream, crowned with a swirl of whipped cream. Five minutes, one frosty mug, zero sugar. Pour slowly and watch the fizz do its thing.
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 (4.9 oz) crushed ice
• 2 tablespoons / 30ml heavy whipping cream
• 12 ounces / 355ml (12 fl oz) 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!

Frequently Asked Questions
Is a cola float keto?
This one is — a serving has 1 g of net carbs with 11 g of fat from the heavy cream and whipped cream, over sugar-free cola.
Can I use a different diet soda?
Yes — any sugar-free soda works. Root beer, cream soda, and orange all make fun variations of the classic float.
Why did my float fizz over?
The cola was poured too quickly. Pour it very slowly over the crushed ice and cream to keep the foam under control.
Do I really need to freeze the mug?
It's worth it — 30 minutes in the freezer makes the float frostier and keeps it cold far longer. Frozen mugs at the ready is the trick.
