Frozen yogurt (also frozen yoghurt ) is a frozen dessert made from or containing yogurt or dairy analogues. Frozen yogurt is a dessert similar to ice cream, but lower in fat.

Frozen yogurt is typically made in an ice cream machine and is typically available with ice cream flavors, and can also be blended with fruit in a frozen yogurt blending machine. Frozen yogurt freezes and melts much slower than ice cream since yogurt has a much higher enthalpy of fusion than milk. Sugar-free versions of frozen yogurt are readily available. Frozen yogurt is often eaten by lactose-sensitive people in place of ice cream, as the live cultures can help digest the lactose. More recently, probiotic frozen yogurt has seen increased popularity, as many consumers may view yogurt of this variety as being healthier.
