Last year the nation came together to celebrate Her Majesty's 90th birthday and it was a lavish affair.

As well as the annual birthday parade, 1,000 beacons were lit across the country in her honour.

This time around, her celebrations for her 91st birthday will be a little quieter.

Why does the Queen have two birthdays?

The Queen celebrates her birthday twice each year - on her actual birthday (April 21) and the other on her official birthday in June (this one has no set date, but it's always on a Saturday).

George II started the tradition for monarchs to have two birthdays in 1748. The reason was actually down to the British weather.

George was born in November and felt it was too cold to host an annual birthday parade. So instead it was decided he would celebrate it in spring at the same time the military parade - known as the Trooping Colours - was held.

The tradition is still observed today.

The most memorable royal cakes

From birthdays to weddings and commemorative cakes, the Royal family really knows how to dazzle guests with amazing creations.

Here are the good, the bad, the ugly and the downright bizarre.

The Queen's 90th birthday cake

The honour of making the Queen's 90th birthday cake was bestowed upon Great British Bake Off winner Nadiya Hussain. But when she revealed the cake publicly onlookers said it looked 'wonky'.

Some critics took to Twitter to voice their disappointment, one user called @mental-nigella_ wrote: "Fancy giving her a wonky cake though".

Nadiya's three-tier orange drizzle cake had a butter cream and marmalade filling and gold and purple icing.

A few days after the backlash Nadiya spoke out when she appeared on Loose Women.

She said: ""If I cared about every little thing people say or that kind of negativity, I don't think I would be able to leave my house," she said.

"So do you know what? I couldn't care less!"

Queen Elizabeth and Prince Philip's wedding cake

Queen Elizabeth and Prince Philip got married on 20 November 1947 in a lavish ceremony attended by 2,000 guests. Their show- stopping four-tier wedding cake was nine feet tall and was nicknamed the 10,000-mile wedding cake after its ingredients were flown to the UK from South Africa and Australia.

In 2015 a slice of the cake was sold at auction for £500. The fruit cake was wrapped in its original parchment and is still edible thanks to its high alcohol content.

The slice had been kept by an unnamed woman from Hove, East Sussex, whose father attended the royal wedding.

Prince William and Kate Middleton's wedding cake

William and Kate opted for not one but two cakes for their nuptials back in 2011.

The 'official' cake was this extravagant eight tier creation.

Its design was inspired by 17 of Kate's favourite flowers. The bakers were also given a piece of lace from her wedding dress which they copied onto the cake.

The future king and queen kept the first three tiers of the cake 'for the future'.

Wills and Kate's chocolate wedding cake

The chocolate biscuit cake was made using a Royal Family recipe and was specially requested by Prince William. It was made by chocolatier Barry Colenso who has also made cakes for the Queen and the late Queen Mother.

The recipe was based on Prince William's favourite childhood treat, the Tiffin cake.

Barry - who worked with McVitie's to make the cake - said it was "rich, indulgent and creamy with a really snappy texture which came from the Rich Tea biscuits".

Prince Charles and Princess Diana's wedding cake

In 2015 a slice of Prince Charles and Princess Diana's wedding cake was sold at auction for £920.

The fruit cake, which has a cream cheese frosting - is still edible more than 32 years after the wedding, again due to its high alcohol content.

It was still preserved in the box that it came in which had silver lettering on. There was also a gift note which read: "With best wishes from Their Royal Highnesses The Prince & Princess of Wales.”

Cadbury's Buckingham Palace chocolate cake

Chocolatiers at Bournville's Cadbury World made this edible version of Buckingham Palace to celebrate the Queen's 90th birthday last year.

It took three days to make and was completed with details like union jack bunting, a picnic basket, balloons, tea sets, sandwiches, cake, flowers, trees and a striped lawn - all made entirely out of chocolate.

It weighed almost 132 pounds and stood 70cm tall. The iconic building was finished with an edible gold and silver lustre and the intricate British royal coat of arms.

Diamond Jubilee cake

This striking creation took two weeks to make and weighed an impressive 66 pounds. It was decorated with fine sugar paste sculptured to represent Her Majesty.

The cake even features one of the Queen's corgis.

It was made in 2012 by The Cake Store bakery .
