No one asked for this McFlurry hash-brown sandwich, but McDonald's fans on TikTok are lovin' it

• PSA: McDonald's fans are making McFlurry hash-brown sandwiches.

• No one asked for the savory-sweet combination but TikTokers are lovin' it.

• TikToker Kelly Arvan, who appears to have created the trend, said it all started with a craving.

Forget dipping your fries into ice cream. McDonald's fans on TikTok are making McFlurry hash-brown sandwiches.

Whether it sounds like heaven or hell to you, the hashtag #mcflurryhashbrownsanga has 1.7 million views as of Tuesday. (For those unfamiliar, "sanga" is an Australian term of endearment for a sandwich.)

The hashtag page shows a stream of videos from TikTokers trying the trend, and many are very in favor.

It appears to have started when Australian TikToker Kelly Arvan (@arvanfamily) posted a video trying the savory-sweet treat on May 20. So far, it has 6 million views.

In her video, Arvan said she was craving an Oreo McFlurry with hash browns one night. Speaking to Today's Heather Martin, Arvan said she went straight to her local McDonald's in Point Cook, a suburb of Melbourne, the next day.

And thus, the McFlurry hash-brown sandwich was born.

Arvan describes the snack in the video as "crunchy, potatoey, sweet," and gave it a "10 out of 10."

The hash brown/McFlurry combo made such an impression on Arvan that she went back to the McDonald's drive-thru to order another version.

In another video that has close to 739,000 million views since it was posted on May 21, Arvan ordered the two menu items, but this time opted for an M&M McFlurry after trying to order other flavors including KitKat and Malteser that she said were sold out. (Other TikTokers trying the treat noted in their videos that the menu items were scarce at certain locations.)

This time, Arvan described the snack as "a 2-year-old's party in a sandwich."

"To the people who say this is disgusting but then dip their chips in their milkshake, you're stupid," she said later in the video.

Arvan regularly posts videos of unique food combinations on her family's TikTok account — which has over 217,000 followers — but, for whatever reason, this one has stuck.

Whether you're lovin' it or hatin' it, the McFlurry hash-brown sandwich is a hit

In her May 29 video, TikToker Bec Hardgrave said the combination was "ten times better" than dipping fries into soft serve.

"I saw a girl do this on TikTok and now it is literally everywhere," she said, seemingly referencing Arvan. Hardgrave added that she drove to multiple McDonald's before being able to get both hash browns and a McFlurry.

She said she'd suggest a structural change, though — using the hash brown as a spoon so it doesn't make a mess. Her video has 545,000 views so far.

When @Jordan_The_Stallion8 ordered the items at his local McDonald's, he said the staff member serving him suggested adding bacon.

In his video, which has over 4.2 million views since it was posted on May 22, he said he told the worker "you're changing a grown man's life right now."

"That is the most life-changing thing I've ever had in my life," he said after taking a bite.

TikToker Danielle (@yescoffeenodecaf) is also a fan. Her video trying the breakfast dessert has over 43,000 views since it was posted on Thursday. Like Arvan, she gave the bootleg ice-cream sandwich "a 10 out of 10," adding that it's "so delicious."

Tasmin Dhaliwal (@tasmindhaliwal) is on board, too.

"That's bomb," she said of the treat in her video, which has over 617,000 views since it was posted on May 25.

And they're far from the only ones.

Arvan and McDonald's did not immediately respond to Insider's request for comment.
