Root Beer Float Cupcakes with Vanilla Buttercream

Want to know why root beer is great?
1. Most root beer sodas are caffeine free which is great if caffeine causes you to get immense headaches or kidney stones. This doesn’t necessarily apply to me but it is definitely nice to have options.
2. It’s got such a different flavor than other sodas. An almost refreshing, spicy sort of flavor. Not your standard cola.
3. Its’ flavor is concentrated into my most favorite candy, root beer barrels. Try them. Now. Your life will be forever changed.
4. It goes great with sweets. Especially vanilla ice cream. Or cake. Or cake with vanilla icing. Oh yes.
When I get in a baking mood (and that doesn’t happen as often as you’d think), I try to make something appealing for everyone in the house. Only because I know that eating an entire batch of cupcakes by myself would make my gut too big to fit into my cute jeans. These popped up on my list a few weeks ago when I realized I had cute cupcake wrappers, root beer extract and old fashioned root beer candies for garnish.
The end result was great. The cake is moist and tasty with a nice punch of root beer flavor. And when combined with the vanilla buttercream, it tastes like a pastry version of my most favorite ice cream treat. I’m thinking these would be a really fun twist for an ice cream social party (which I will so be having when spring or summer rolls itself around again!).

  1. Can’t wait to try these. Made root beer float cupcakes a few years ago and they were very heavy. I’m hoping these will make up for the last ones!
