Heat the milk for 30-45 seconds in your microwave in the cup you intend to drink your coffee from.
Once the milk of your choice is heated, take a small whisk and vigoursly whisk back and forth for 15-30 seconds until the milk is frothy.
Pour the coffee directly over the frothed milk or brew over the frothed milk.
Alternatively, you can heat the milk in a glass measuring cup and then froth. Pour coffee or espresso into a mug and then gently pour the frothed milk over the coffee. Spoon the remaining foam on top of your latte.
For a dairy-free/vegan latte, use non-dairy milk such as almond milk, coconut milk, or soy milk.
Sweetened Latte--add 1-2 teaspoons your choice of sweetener to your milk of choice BEFORE heating milk.
Vanilla Latte--add 1/4 teaspoon vanilla extract to milk before after heating milk but before you add coffee.
Chocolate/Mocha Latte--add 1-2 tablespoons chocolate syrup to milk BEFORE heating milk.
