Fill a highball glass with ice.
Pour 60ml Baileys Irish Cream over the ice.
Add 30ml Frangelico hazelnut liqueur.
Pour 60ml whole milk over the top.
Stir gently to combine.
Serve immediately.
Whole milk is preferred here for its fat content, which binds the cream and hazelnut liqueur into a cohesive, silky texture - avoid skim milk as it can make the drink watery and cause slight curdling with the Irish cream.
