So THIS is the reason McDonald’s Egg McMuffin sales are soaring

McDonald’s have recently seen a huge surge in the sales if their famous Egg McMuffins, and it’s all down to just one minor change of ingredients.

The fast food giant has stopped using margarine and instead, is spreading old fashioned real butter on its muffins.

And this little trick is working a treat for McDonalds and its customers alike, with a 0.9 per cent growth in sales across the US.

The fast food restaurant has also started toasting its buns longer (to get that little extra crunch!) and amending the way they grill their burgers too.

According to Forbes, chief brand officer Steve Easterbrook said: “People have more choices than ever about where to dine.”

“We want to give them more reasons to dine at McDonald’s by recommitting to hot fresh food, fast friendly service and a contemporary restaurant experience.”
