My grandmother claims this Whiskey Chocolate Chunk Coffee Milkshake recipe (well, the combo of whiskey, chocolate, and coffee at least) is her secret to longevity and I ain't gonna argue with that!
Using a peeler, shave or peel off the edge of the chocolate bar to make some shavings for garnish, then finely chop the rest. Combine ice cream, milk, and whisky in a blender and process until just smooth. Stir in the chopped chocolate and serve garnished with the chocolate curls.
