Is it your birthday? You can now have tears of joy all you want! The famous soft drink producers at Dr. Pepper have introduced a new way to baffle their customers, with possibly the most confusing recipe ever.

Supplying with their traditional riff on root beer, the beverage brand is venturing into uncharted territory. With cake-flavored soda, Dr. Pepper offers its fans a novel way to celebrate their birthdays without baking.

And if you're wondering why you haven't seen this flavor on shelves, it's because it's super exclusive. A Twitter user, @JKMerm, who posted a picture of the can, explained:

"I'm part of the Pepper Pack, which is the Dr. Pepper brand ambassador program! They sent me a few cans of this for my birthday!"

According to several social media posts, the new limited edition of this beverage was introduced to the market in 2018.

However, cake-flavored soda remains unknown, thanks to the complicated way in how fans can get their hands on the drink. The beverage is only available to members of Dr. Pepper's exclusive "Pepper Pack" club.

Described as an elite "squad" of 23 of the drink's most enthusiastic fans, the Pepper Pack allows members exclusive access to a range of limited flavors, including the birthday cake.

The flavor comes complete with a hat, balloon, and a note thanking the receiver for their work as a Dr. Pepper ambassador.

The note reads:

"To the Birthday Pepper, Since you're a die-hard Dr. Pepper fan, your birth month is, well, kind of a big deal to us."

"So, to celebrate, we've created a limited-edition Birthday Cake-flavored Dr. Pepper and some exclusive party supplies to help commemorate your existence. Don't drink it all in one place. Or do. It is YOUR birthday after all. Happy birthday, The Dr. Pepper Team."

The maroon, white, and sprinkle-covered can indicates that the Icing on the Cake flavor is limited-edition.

Now, to answer your eagerly waiting question weighing on your mind, "HOW DO I GET THIS FLAVOR?!" You're required to first show your devotion by applying to join the Pepper Pack.

To join the Pepper Pack club, you need to be a die-hard fan of Dr. Pepper and have a social media account.
