I drank one of those recently - as a shot.

It was not icky at all. It tasted like, well, pb+J

My personal favorite in the category of 'tastes like what it's named for' is:

Oatmeal Cookie

1/4 oz Goldschlager® cinnamon schnapps
3/4 oz DeKuyper® Buttershots liqueur
1/4 oz Bailey's® Irish cream


var. 1 - Pour the Goldschlager into the bottom of a 1.5-oz shot glass. Add the Buttershots butterscotch liqueur, float the Bailey's on top, and serve.

var. 2 - Combine ingredients in a shaker with ice. Shake, strain and serve.
