McDonaldland Milkshake Review: Our Mystery Flavor Guess

The fast-food giant has been playing coy with us.

When McDonald’s announced earlier this month that it was launching a new limited-edition milkshake flavor called the Mt. McDonaldland Shake, the company declined to disclose what exactly the drink would taste like.

Of course, we love a mystery, so we got our hands on the new McDonald’s milkshake as soon as we could.

What does the Mt. McDonaldland milkshake taste like?

The “secret concoction” that the company said makes up the Mt. McDonaldland Shake is said to be inspired by the fictional mountain’s “vibrant blue ‘lava’ and pink clouds.” In terms of an actual flavor profile, I’ve got to say this milkshake lives up to the surprisingly expansive lore.

The milkshake has a fruity, berry-forward taste that immediately recalls the nostalgic, slightly unnatural blue raspberry flavor that was so ubiquitous in popular candy of the ’90s and early aughts. There are hints of both blueberry and raspberry present, but mainly it’s a sweet (but somehow not too sweet) sip of childhood for a millennial like me.

As for the pink whipped topping, it mostly tastes like your standard-issue McDonald’s vanilla flavor—though I could be imagining a slight undercurrent of bubble gum present as well.

Adding to the nostalgic flair of the milkshake—which cost $17.29 as part of the McDonaldland Quarter Pounder with Cheese Meal—is the collectible tin that comes with it. My meal came with a tin dedicated to the iconic Hamburglar, and I was honestly impressed by the over-the-top design of the postcards and stickers, including the Hamburglar’s McDonaldland Passport.

How long is the Mt. McDonaldland shake available?

The Mt. McDonaldland Shake launched on August 12 and is a limited-time offering, so it’s not anticipated to be available from the chain for too long. If you want a taste of the throwback goodness for yourself, you should head to a McDonald’s soon.
