Soda Cupcakes

I saw a similar recipe on Pepper Please. I thought I could make them a little bit my own by using Rootbeer and orange cream soda.

1 box of vanilla cake mix
1 can of Rootbeer or orange cream soda
1 tablespoon of margarine
Milk
Powdered sugar
3 drops of Rootbeer concentrate or orange extract

Pour the box of cake mix into a bowl and add the can of soda. DO NOT add the eggs, oil etc. as directions on the box state. Bake as directed on the box. Allow to cool. Combine margarine, icing sugar, milk, concentrate/extract to make the icing. I used 1 tablespoon melted butter, 1 tablespoon milk, and about a teaspoon of which ever flavoring you choose and add in the powdered sugar until you get a consistency/flavor you like. Mine turned out more like a glaze which made the cakes look fancy.
