Milk frothers are coffee tools used to heat and aerate milk so it becomes light, creamy, or lightly foamed for milk-based drinks. This category includes both handheld and electric frothers designed to work with hot or cold milk, allowing you to prepare milk for cappuccinos, lattes, flat whites, and similar drinks without needing a built-in steam wand. They sit alongside your coffee maker or kettle and handle the milk portion of the drink in a simple, repeatable way.

Some frothers are compact handheld tools that you use directly in a cup or small jug, while others are countertop units with a container that heats and froths the milk at the same time. Both styles use a fast-spinning whisk or internal mixer to introduce air into the milk, changing its texture and thickness. This makes it possible to create anything from lightly warmed milk to a thicker, spoonable foam, depending on how the frother is designed and how long it runs. Milk frothers fit into a home coffee setup when you want more than just black coffee but do not want the size or complexity of a full espresso machine.
