I haven't really been drinking a lot of dairy in the first place, so combining that with beer is fairly unsettling at the moment.
I'm cautious about cream in alcohol drinks generally. Too much acid or alcohol and it's curdle time either in the glass or while drinking it. I have only 1 drink recipe that I trust for it and it requires a very specific vodka. Here's my best recollection of it.
2oz Vincent Van Gogh triple espresso vodka
(it's the only "coffee" vodka I know of that is actually made of coffee)
3oz Irish Cream
(the cheaper stuff like Feeny's is usually great. Bailey's is overpriced and overrated)
Chocolate syrup to taste
Lindor Truffle of choice
The key here is in bringing down the vodka alcohol content some before adding the Irish cream.
In shaker glass filled with ice add room temperature vodka and chocolate syrup if desired. Cap and shake until your hands feel the cold. Add room temp cream and shake again for a few more seconds, but not much more as further dilution is undesirable, this is martini strength. Pour into martini glass and add a speared truffle or two like olives.
I have no name for this one, but the caffeine in the vodka, sugars and Irish in the cream, and the easy way they go down tends to get people very chatty very quickly. Good for holiday get-togethers and "soft" interrogation.
