Fast Food Style Milkshakes at Home: Thick, Creamy, and Simple

Fast food style milkshakes get their thick, spoonable texture from a high ratio of ice cream to milk and a short, controlled blend that keeps air out. Use full-fat vanilla or a flavored ice cream, just enough whole milk to get the blades moving, and blend in short pulses rather than one long run, and you'll land close to that dense, slow-melting texture without any special machine.

Why Are Homemade Milkshakes Often Thinner Than the Fast Food Version?

Most homemade shakes turn out thin because they use too much milk relative to ice cream, or blend for too long, which whips air into the mixture and melts the ice cream faster than it should. Fast food shakes are built with a much higher ratio of ice cream to milk than most people use at home, and they're served immediately after a short blend, before the ice cream has a chance to soften and separate.

What Ice Cream Works Best for a Thick Shake?

Use a full-fat ice cream with at least 10% milkfat, since low-fat or "light" ice creams don't hold their structure once blended and turn watery fast. Let the ice cream sit at room temperature for 5 minutes before blending so it's soft enough for the blades to catch without forcing you to add extra milk to compensate.

How Much Milk Should You Add?

Start with less milk than you think you need. A ratio of about 3 cups of ice cream to 1/3 cup of milk produces a shake thick enough to need a spoon, and you can always blend in another splash if it's too stiff for your blender to handle.
