Luisa turned 27 yesterday (4 June) and was treated to the yummy treat along with a surprise party attended by all her family and friends.
Although she admits she is "hungover" today, the former Apprentice star clearly had a great night at the bash.
The party was held at The Penthouse in the exclusive May Fair Hotel in London and Luisa has since shared some pictures with fans that were taken on the night.
Alongside two shots of the dinner menu and a table surrounded by her loved ones, Luisa said: "Omg surprise birthday party with all my nearest and dearest, can't believe everyone kept it secret from me!!!"
She also posted a picture of her birthday cake, which was placed on a high table alongside a gorgeous and huge photograph of Luisa and Dixie.
"How amazing is my cake?!!!! Can't believe I have an amazing surprise birthday party!!!" she gushed.
Despite having a sore head following her amazing night, Luisa has since logged back onto Twitter to share a selfie taken during the event.
She told her followers: "Birthday selfie from last night very hungover today!! This dress is by Alaia."
Luisa has got a big day in store, as the new series of Big Brother kicks off tonight.
Last month, it was revealed that Luisa has landed a job as a panelist for Big Brother spin-off Big Brother's Bit On The Side.
Happy birthday, Lu!
