Mix the hot espresso with the cookie butter and salt, making sure that all the cookie butter is mixed into the hot espresso and the mixture is completely smooth.
Mix in the milk.
Fill your serving glass half full with ice, then pour in the latte and serve.
Recipe Notes
To make this latte hot, you may need to increase the amount of milk you use if the drink is too intense with the original amount. Steam or heat the milk before adding to the espresso/cookie butter mixture, then serve hot!
