While Starbucks has yet to officially announce the new option, it ties into the chain's commitment to create a greater animal-free offering.
During a shareholder meeting in March 2018, Starbucks COO Rosalind Brewer promised to increase the chain's vegan options.
She said: "We have a line that we'd love to share with our customers later this year, so it is in our plans. We know our customers ask us that repeatedly, and we’ll be responding."
Throughout 2018, Brewer made good on her promise, with a range of items launching in various countries. Four food products launched in the UK in June alone.
These included two wraps - kale, jalapeno and slaw, and sweet potato falafel, as well as a raspberry chocolate cake, and mango fruit pot.
They followed the launch of oat milk and Starbuck's bbq jackfruit wrap - which the company said were requested by customers.
