These Root Beer Float Cookies taste like summer! Two root beer cookies sandwiched together with vanilla frosting and taste like root beer floats.

There’s something magical about a root beer float.

The bubbly sweet concoction that fizzes when poured over several scoops of creamy vanilla ice cream.

Which is funny because I drink root beer on its own maybe twice a year, usually when I need a drink on the go. Even then, I don’t choose it unless my only other choice is Pepsi or Mountain Dew.

But pour it over ice cream, and I’m all in.

Of course, root beer floats aren’t exactly take-along treats, especially out in the hot sun. Last year I made root beer cupcakes.

This year I made Root Beer Float Cookies – two chewy root beer cookies with vanilla cream in the middle.

They taste exactly like a root beer float in cookie form!

I wonder who thought of root beer floats. Did that person think “hey what if I mixed together root beer and vanilla ice cream?”

Or maybe it was a happy accident where someone knocked root beer into a bowl of ice cream. I need to shake that person’s hand for inventing it.

A little secret – there is no actual root beer in these cookies.

You’re familiar with vanilla extract, yes? I used root beer extract for the flavor. McCormick is the brand I’ve seen most, which you can buy in store or online at Amazon.

It smells and looks just like root beer.

For the filling, I scraped a vanilla bean pod into buttercream frosting because I wanted that authentic vanilla bean ice cream flavor and look (although substituting vanilla extract works the same).

If you’re feeling really adventurous and don’t have anywhere to go, use a scoop of ice cream to make ice cream sandwiches.
