Because there’s so much going on in this cocktail, the taste of the vodka is mostly obscured. This means there’s no need to reach for the top shelf; using an inexpensive vodka in your Mudslide is fine, so be sure to save the good stuff for your next Martini. You could also try different vodka variations, like vanilla or raspberry vodka to impart more flavour and sweetness.
Not a coffee person? While there are only very small amounts of caffeine in coffee liqueur, if you don’t want to take the risk of it messing with your sleep, or simply don’t like the taste of coffee, you could try a hazelnut liqueur instead, which always pairs well with chocolate. Liquid Ferrero Rocher cocktail, anyone?! Try adding ice-cream instead of double cream if you'd like a frozen, slushy-like cocktail that's even more decadent than the original – just be sure to let your blender run for longer to ensure all the ingredients are fully mixed.
