Introduction
This keto novelty soda float mocktail has the look and taste of an old-fashioned soda float, built to keep carbohydrates low. It takes a few minutes to make, which makes it an easy treat at the end of a long day.
Save this recipe for later:
Sugar-free soda and heavy cream give it a creamy, fizzy body, and a little vanilla extract and keto-friendly syrup round out the flavor. Each serving has 150 calories and just 1 gram of sugar.
Make one for yourself or a few for a small gathering. Grab the ice cubes and pour in the soda; the rest takes a minute. Staying on keto can still taste like a treat.
Key ingredients
Sugar-free soda (1 cup)
Sugar-free soda is the base. It brings the fizz and the familiar soda flavor without the carbs, so use whichever brand you like best.
Heavy cream (1/2 cup)
Heavy cream gives the float its rich, smooth texture and stays keto-friendly. It softens the sharp bubbles of the soda and makes the drink feel indulgent.
Vanilla extract (1 tablespoon)
Vanilla extract adds a warm, aromatic note, the flavor most people expect in a float.
Chilled keto-friendly syrup (1 tablespoon)
The syrup sweetens the drink without added sugar. Use more or less to taste.
Ice cubes
Ice keeps the mocktail cold, which matters most on warm days, and a glass full of cubes looks the part.

Why you’ll love this recipe
It is sweet, fizzy and creamy in one glass, and it brings back summer soda floats without the sugar and carbs. With 150 calories and 1 gram of sugar per serving, it stays on-plan.
It is also fast. In five minutes you can have a drink ready for guests or for yourself, and you can change the soda flavor every time you make it.
Variations
Flavored soda options
Try other sugar-free flavors, from lemon-lime to root beer. Each one changes the character of the drink, so you can match the mocktail to what you feel like that day.
Add fresh ingredients
A few strawberry slices or a sprig of mint add freshness and look good against the creamy drink.
Mix up the cream
Coconut cream can replace the heavy cream for a more tropical drink. It adds a light coconut flavor and keeps the drink just as rich, a good choice if you like coconut or want a change from the original.

Cooking tips and notes
Perfecting your mocktail
Chill all the ingredients beforehand. Cold ingredients keep the drink refreshing and help the soda hold its fizz.
Adjusting sweetness
Adjust the amount of keto-friendly syrup to your taste. Make it sweeter or lighter to suit your mood. Switching soda flavors is another easy way to find a combination you like.
Presentation matters
Serve it in a tall glass with a straw, or garnish with fresh mint leaves or berries. It makes the drink feel a bit more special, at home or with friends.
Serving suggestions
Tall, clear glasses show off the layers of soda and cream, and a colorful straw makes it feel festive.
For guests, set out keto-friendly snacks alongside: a cheese platter, vegetable sticks with dip or low-carb desserts. Everyone stays within their eating plan.
Garnish with fresh mint leaves or a slice of lemon for color and aroma. It is a good drink for a sunny afternoon or for friends who eat keto.
