Chocolate cupcakes with root beer extract and fluffy vanilla frosting

Ever since I discovered root beer extract I have been dying to make these cupcakes. Root beer is reminiscent of summer to me.  I love root beer but I don’t drink it often because of the added calories. Last week at the lake I enjoyed several thirst-quenching bottles. For lunch we would hop in the boat and drive across the lake to a little restaurant/shop called Miller’s Landing. I indulged myself with Oreo milkshakes, chicken strips, French fries and root beer; not all at once of course.

So these Root beer cupcakes are perfectly reminiscent of the lake. This is a chocolate based cupcake loaded with root beer flavor and topped with a fluffy whipped vanilla frosting. I have kind of been into the fluffy whipped frostings lately. The root beer flavor comes from a liquid called root beer concentrate. I searched high and low for it but ended up finding it at Walmart! These cupcakes are really easy to make and are sure to be a crowd pleaser!

There is something about vacation that makes you feel less guilty about Oreo shakes, chicken strips and root beers. I wish vacations lasted for longer!
