Begin by brewing your shot of espresso into a latte mug.
In a saucepan, combine the milk, brown sugar, ground cinnamon, and vanilla extract. Heat until the sugar is dissolved and the milk is steaming.
Froth the milk mixture until it’s creamy and has a smooth texture.
Pour the frothed milk over the espresso.
If desired, top with whipped cream.
Garnish with a sprinkle of crumble topping or ground cinnamon for that authentic coffee cake feel.
