McDonald's fans know there stuff and this latest hack could save you money and a trip to another chain.
And it's even better if you are guilty of grabbing an iced coffee or a frappe every time you pass a coffee shop.
A woman has gone viral on TikTok after sharing a very simple, yet 'amazing', McDonald's milkshake hack after a recent trip to the golden arches.
The fast-food chain customer, who posts under the name @ellbrxo, showed how you can make a drink that is similar to something you might find at Costa or Starbucks.
But with this trick, you just need to head straight to McDonald's.
All you have to do is head to your local Maccies and order a vanilla milkshake and a shot of espresso, according to the Mirror.
Then all you need to do is pour the coffee into the milkshake and give it a stir with your straw - couldn't be easier!
Shared the video of herself mixing up the drink, El captioned the post "thank us later".
And it looks like plenty of people did with the video racking up more than 270,000 views and a lot of comments.
A McDonald's staff member even approved the drink, writing: "I work there and I do this all the time!!"
Well, we know what to do on our next trip.
