Alison turns 47 on Saturday, February 5, and wanted to get the party started on the ITV show.
"So where's the cake?" the nearly birthday girl asked moments into This Morning starting.
"Alright, calm it," Dermot jokingly hit back. "We know it's your birthday...
"Listen, let me take control for a second, it's a special day for Alison."
"I'm joking, I'm joking," Alison tried to resist but it was too late.
Dermot emerged with a Baileys-themed cake as Stevie Wonder's Happy Birthday rang out through the studio and confetti rained down on the hosting duo.
"Thank you so much, can I eat it now?" Alison asked as Dermot replied: "Yeah, you can stick your head right in there!
"It's got Baileys buttercream," he confirmed.
"Well we might as well have bit of a tipple now, start the show off as we mean to go one," Alison said as she opened a mini bottle of the Irish cream liqueur.
She then struggled to cut the cake and as she put a slice on her plate, more crumbled from the once perfect celebration treat.
But This Morning viewers couldn't get enough.
"I don't know what was more uncomfortable to watch, the way @AlisonHammond cut her birthday cake or @Josiestweet dressed as a no entry sign. I was not prepared #ThisMorning @thismorning," @TheRealKYL3 said.
@Attila_hun tweeted: "OMG ALISON!!!! LOL #ThisMorning."
