Throughout her 70-year reign, the Queen has been somewhat a creature of habit when it comes to her morning routine.
She reportedly wakes up at the same time before following the same schedule every morning.
One of the first things she does on waking is have a cup of Earl Grey tea, with no sugar and the occasional drop of milk.
And to satisfy her sweet tooth, she has a few biscuits to go with it - specifically Chocolate Bath Olivers.
Former royal chef Darren McGrady revealed Her Majesty's pre-breakfast biscuit of choice, which is made by biscuit company Huntley & Palmers, reports My London.
The firm says on its website: "Rich, dark chocolate, generously enrobed around a crisp slow-baked biscuit Chocolate Olivers are the ultimate biscuit indulgence, made using a patented recipe from the 1930s, which includes hops and malt, with the thickest, richest dark chocolate."
However, they aren't cheap, a 200g tin from the company's website will set you back £8.49.
It's well-known that the Queen enjoys sweet foods, and Darren has previously described her as a "chocoholic".

He said: "She is absolutely a chocoholic. Anything we put on the menu that had chocolate on, she would choose, especially chocolate perfection pie."
In recent pictures showing the inside of her Oak Room sitting room at Windsor Castle, r oyal fans have spotted boxes of chocolates on side tables.
When she welcomed two defence staff officials in the room in February, a £5 box of Benedick's mint chocolates was seen on a table as well as a Fortnum & Mason's Milk & Dark Chocolate Selection Box, which can cost up to £220 depending on the size.
And it seems that her sweet tooth is something that her grandson Prince William has also inherited.
During a video call to schoolchildren before Easter a few years ago, his wife Kate revealed that he couldn't stop eating their supply of chocolate.
As the couple wished everyone a Happy Easter, William reassured them: "There will be a lot of chocolate being eaten here, don't worry!"
Before his wife quickly replied: "You keep eating it!"
