Rich, thick, sweet, and cold; what’s not to love about shakes? The blended concoction made with ice cream and milk — or blended ice and milk — or ice cream and malt — is truly the quintessential summer treat.

What's the difference between a "frappe" and a "milkshake"? It's a regional thing, and it gets complicated. You can learn more about that here. No matter the name, we’ve found some of the tastiest around for you to enjoy this weekend. Check them out:

The Chocolate Malted Frappe at Cabot's

When it comes to truly classic fountain drinks, Cabot's Ice Cream is King. The Newton-based icon has been around since 1969, and their chocolate malted frappe is locally famous. Ice cream is carefully blended with lots of chocolate syrup and malt and served in classic shake glass. Make sure you grab a couple of spoons if you're sharing - this thing is thick!

Cabot's also has vanilla, strawberry, coffee, mocha, black raspberry, pineapple, and cherry flavored syrups, if chocolate isn't your thing. They also have every other type of ice cream creation you can possibly think of, if a shake isn't the only treat on your mind.

The Expresso Frappe at Amorino Gelato

Amorino Gelato is a smaller, world chain that offers authentic Italian gelato, hot and cold drinks, and sweet treats including a variety of gourmet Frappes.

We recommend the Espresso Frappe; made with a coffee gelato and fresh Chantilly cream. it's lighter than our other recommendations, but just a refreshing and includes a little caffeine kick for an afternoon pick-me-up. Try the tiramisu frappe If you're looking for something sans the coffee. The creamy, smooth texture and homemade whipped cream are a sweet delight.

Don't forget to pick up some macarons while you're there; they're an Amorino specialty and come in a variety of flavors including mango, and caramel.
