Introduction

Okay, this might actually be the easiest recipe of all time. One ice-cold root beer, a little bit of heavy whipping cream, and a scoop of So Delicious no sugar added coconut milk ice cream. It practically makes itself.

When we first started to change our diet, the thought of having to give up soda gave me nightmares! Kasey used to call me “The Soda King”, a title I probably deserved. The good news is I didn’t have to give up soda. Zevia sweetens its sodas with stevia instead of sugar, and its root beer is the one we reach for here — it tastes like root beer rather than like a diet version of it, which is the only thing that matters once there is ice cream floating in it.

The ice cream is So Delicious’s no sugar added coconut milk vanilla. I can honestly say this stuff tastes just as good as regular vanilla ice cream, and in a float it does the job a vanilla ice cream has to do — it softens into the soda instead of sitting there in a lump. A float takes a quarter cup of it, which is a modest scoop; check the carton for the carbs in that, because formulations change and the pint is not the portion.

Put them together and you have a root beer float, which is the whole recipe. Three ingredients, one glass, about three minutes. It reads like a summer drink, but there is nothing in it that stops working in February.

If you would rather have it as a dessert you slice, our root beer float pie folds zero-sugar root beer into a sugar-free vanilla pudding filling over a baked almond flour crust.

Where you see an em dash: one of the ingredients in this recipe does not publish a figure for that row, so we cannot add one up honestly. We would rather show you nothing there than a zero we cannot stand behind.

About these numbers: We are home cooks, not certified nutritionists. Nutrition is shared as a courtesy. We pick a representative product for each ingredient, and our recipe system works out the totals from the amounts in this recipe, so please treat them as a helpful estimate rather than a guarantee. The brands you buy, any swaps you make, and how generously you portion the recipe will all move these numbers.

Directions

  1. Pour 2 tbs heavy whipping cream into a 16 oz glass.

  2. Pour 1 12 oz can of Zevia root beer into the same 16 oz glass.

  3. Scoop out 1/4 cup of So Delicious coconut milk ice cream into the glass.

Correction — October 15, 2026: We had described the ice cream's carbs by the pint. A float uses a quarter cup of it — check your carton for the nutrition of that portion.
