For those of you who aren’t beer connoisseurs, Lambic (officially called Francois Lambic) is a type of Belgian beer that includes fruit. Francois Lambic is made with raspberries. To go along with the raspberry flavor in the beer, these cupcakes also contain sour cream and unsweetened cocoa, among other things. The frosting has raspberry puree in it, adding to the overall fruit flavoring. One word of warning: adding alcohol to cupcakes means that they instantly become adult-only treats!
