Root Beer Float Cupcakes Recipe

Wednesday, November 7, 2018

The Cherry on Top Ice Cream Float Party was full of great details as well as great recipes! Pulling together themed sweets is one of my favorite parts of party planning. I didn't find just the right root beer float cupcake recipe, so I adapted a recipe from Life Love Liz for the cake. Then, I modified my absolute favorite buttercream recipe for a Root Beer Buttercream that is both great for piping and delicious.

Adorning the root beer cupcakes with cherry sours and paper straws makes them extra festive. Besides root beer, the other special ingredients for adding flavor is root beer concentrate.

Root beer floats have a nostalgic feel to me. They aren't a treat we enjoy as a family regularly. Of course, that may change after the having this party. A cupcake version of a root beer float is new way to enjoy the flavor combination associated with root beer and vanilla ice cream.

Spoon the batter into the cupcake liners, filling them 2/3 full.
