Pour the Grand Marnier into a shot glass or small mixing glass.

Add the hazelnut liqueur to the glass, layering it carefully over the Grand Marnier by pouring slowly over the back of a bar spoon.

Layer the Irish cream liqueur on top using the same technique, pouring gently over the back of a bar spoon to create distinct color separation.

Serve immediately in the shot glass, instructing the drinker to either shoot it at once or sip slowly to taste the distinct layers.
