PREPARE ESPRESSO:
Brew 4 shots of espresso, 2 per drink. For a stronger drink, brew 3 shots of espresso per drink.
While still hot, stir in brown sugar or mocha sauce to your desired sweetness until fully dissolved. Set aside.
MAKE TIRAMISU FOAM:
In a mixing bowl or using a handheld frother, combine 1/4 cup heavy cream, 2 tablespoons mascarpone cheese, 1 tablespoon simple syrup, and 1/2 teaspoon vanilla extract.
Whip until the mixture thickens slightly, forming a soft, pourable foam.
HOT LATTE:
Heat 1 cup of milk until steaming, but do not let it boil. Froth if desired.
Pour the sweetened espresso into a mug.
Add the steamed milk, filling the mug almost to the top.
Spoon the sweet foam generously over the top.
Sprinkle with cocoa powder or chocolate shavings if desired.
ICED LATTE:
Fill a glass with ice.
Pour 1 cup of cold milk over the ice, leaving room for the espresso.
Slowly pour the sweetened espresso over the milk to create a layered effect.
Top with the sweet foam, letting it cascade over the ice.
Finish with a dusting of cocoa powder or chocolate shavings if desired.
