A Walk Down Memory Lane

On a whim, while chatting with Charlotte The Great about her younger days, she reminisced about working at the “Float Counter” in a small-town pharmacy, serving soldiers Peanut Butter and Pickle sandwiches alongside Root Beer Floats. Inspired by her stories, we decided to bake root beer cupcakes and topped them with the smoothest, most delicious Root Beer Buttercream Frosting.

The result? Moist root beer cupcakes with just the right amount of flavor, crowned with a frosting that was literally “the icing on the cake.” It was the perfect combination—bringing back memories of those classic root beer floats without overwhelming the palate.

Fun Fact: The Origin of the Root Beer Float

Did you know? The root beer float was created on August 19, 1893, by J. Wisner, the owner of Cripple Creek Brewing in Colorado. He was inspired by the snowy peaks of Cow Mountain, which reminded him of ice cream floating in soda. This brilliant idea led to the creation of the iconic root beer float, a treat that continues to delight generations.

The Perfect Root Beer Buttercream Frosting

This frosting is everything you love about root beer floats, minus the fizz and bubbles. The rich flavor of root beer concentrate blends beautifully with the creaminess of the buttercream, making it an irresistible topping for any dessert.

A Little About Buttercream Frosting

This Root Beer Buttercream Frosting falls under the category of American Buttercream—a simple and classic frosting made by creaming together butter, confectioners’ sugar, and a liquid like milk or cream until it’s smooth and fluffy. Other types of buttercream include:

  • Meringue-based Buttercream
  • French Buttercream
  • Custard-based Buttercream
  • Rolled Buttercream

American Buttercream is known for its simplicity and sweetness, with a typical ratio of twice as much sugar to fat. Whether you use salted or unsalted butter, high-quality butter will always yield the best results. Consider using Plugra for the whitest, gourmet buttercream, or Land O’Lakes Unsalted Butter for a mild, creamy texture.
