This McDonald's muffin is so hard, even a hammer can't break it

Though McDonald’s arguably makes some of the best fast food chicken nuggets and french fries, one thing the chain isn’t really known for is its breakfast pastry offerings.and there’s a reason why.On June 13, TikTok user Rebekah Kushnier shared a video of the muffin she ordered from McDonald’s.At first glance, the muffin looks appetizing; however, when Rebekah tries to break off a piece to eat, she simply can’t.In the video, she bangs the muffin against a window, throws it on the floor and even hits it with a hammer — all to no avail.Fellow TikTok users were concerned about how “stale” the muffin was.“That’s a weapon at this point,” one person joked. “That’s not a muffin that’s a rock,” another user said.Some current and former McDonald’s employees noted that they’ve encountered such inedible muffins before
