The workshops, which are priced at £42 per person, will allow families to decorate and eat cupcakes while enjoying panoramic views of the London skyline.
The special Easter experiences will take place on Saturday, April 12, Sunday, April 13, Saturday, April 19, and Sunday, April 20, with two sessions available on each day at 3pm and 3.30pm.
Each climber will have the opportunity to decorate a vanilla cupcake with icing, sprinkles, chocolate eggs, and more, before relishing the sweet treat at the 52m-high summit.
Climbers will also have time to capture photos with the Easter bunny.
Dan Hurst, Head of Attractions at Up at The O2, expressed excitement about the new family activity.
He said: “We are all about elevating your Easter plans with a unique and memorable experience, and we can’t wait for people to enjoy a sweet Easter treat with the best views in London.”
