I LOVE root beer floats. Every summer I hunt down Abita root beer (the best!) to make ice cream floats.
It’s bubbly, sweet, and basically dessert in a tall glass.
I wanted to try making a matcha version and used the same idea of taking a soda base and adding ice cream.
I recently made matcha soda so this recipe was super easy to figure out since the all I needed to do was add ice cream.

Look to spend around $15 – $30. - Vanilla ice cream, carbonated water, and sugar

One with a spout makes it easier to pour. - Measuring cup

To serve the ice cream float.
The first step is to make the matcha syrup which is the base for a matcha soda.

Next is the bubbly part. Add seltzer water about halfway.
Add a scoop of vanilla ice cream.

Then another scoop.
Top the whole thing with more seltzer water and watch it fizz.
Done! Just make sure to stir everything together with a spoon or straw to make sure the matcha syrup from the bottom gets mixed with the seltzer water and the ice cream.
Matcha Ice Cream Float Tips
- Use seltzer water instead of club soda or sparkling water since it has the cleanest taste without the mineral flavor.
- Try matcha ice cream instead of vanilla if you want it to be super matcha-y.
- I add ice cream halfway so that the drink doesn’t overflow and cause a mess.
