Billed by the resort as the 'ultimate room for chocolate lovers', the sweet suite sleeps up to six people and boasts 'full-on Cadbury chocolate factory theming', including Dairy Milk's signature purple colouring.
The space is divided into two living areas, with a bedroom and a separate room with sofa bed and bunk beds, along with a family bathroom.
Along with a mini fridge containing complimentary water, there's also a supply of Cadbury chocolate hidden in the room - which is all yours, if you can find it.
The Alton Towers website says: "Welcome chocolate lovers to your ultimate sleepover dream!
"Step inside this sensational Cadbury chocolate factory themed suite and explore the mechanics and secret hideaways for tasty treats and exciting surprises.
"There's also a code to crack to unlock a safe oozing with more delicious delights! Have a chocolicious stay!"
The room features Cadbury-themed décor, with purple walls, pressure dials on the wall, pipes on the ceiling and bags of cocoa beans - enough to make it feel like you're in your own chocolate factory.
Janet Gurr, hotels and accommodation development director, said: "We were really excited to partner with Cadbury to create our new chocolate room.
"After a fun-filled day of thrilling world-class roller coasters and splashtastic water rides, families can continue the magic in the chocolate factory themed suite and hunt for the hidden chocolate bars.
"We pride ourselves on creating thrilling, memorable and innovative experiences and we're sure our guests will love the latest addition in our portfolio of unique themed suites."
Bookings are being taken for the new suite from 17 May.
