Which of the following is a cocktail made with equal parts Frangelico and vodka?

The cocktail made with equal parts Frangelico and vodka is indeed the Chocolate Cake. This cocktail is known for its unique and flavorful profile, combining the nutty, sweet characteristics of Frangelico, which is a hazelnut liqueur, with the neutrality and smoothness of vodka. The balance achieved by using equal parts allows both ingredients to shine, resulting in a deliciously rich drink that is often served as a shot or in a cocktail glass.

In contrast, the Lemon Drop is a tangy and sweet cocktail primarily featuring vodka, lemon juice, and sugar, focusing on a fresh citrus flavor. The Mind Eraser is a layered cocktail with vodka, coffee liqueur, and club soda, which does not include Frangelico. Lastly, the Manhattan is a classic cocktail made with whiskey (usually rye or bourbon), sweet vermouth, and bitters, completely different from the flavor profile of Frangelico and vodka combinations. Each of these cocktails serves a different taste experience, which emphasizes why the Chocolate Cake is distinct in its composition.
