Dream Pops will be available between 2pm and 5pm until October 5 at at La Brea and 4th, Melrose and Stanley, Santa Monica's Third Street Promenade, Wilshire and Santa Monica, and San Vincente and Barrington.
According to reports, if the launch is successful, the pops - which come in a range of flavors including chocolate - could potentially roll out nationwide and beyond.
Posting about the collaboration on Instagram, Dream Pops said: "We're thrilled to announce our exclusive partnership with Starbucks...Head to one of our select stores to get your daily coffee fix and cool down with a delicious Dream Pop."
The pops are soy and gluten-free and contain fewer than 100 calories and seven grams of sugar each.
Speaking about the product, the brand says: "We are proponents of healthy lifestyles and ice cream's appeal is undeniable, but its allure has also stunted its potential to change with the times...by creating a flavor-packed plant-based alternative powered by real food and real ingredients, we're rewriting culinary history."
During a shareholder meeting in March Starbucks COO Rosalind Brewer 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."
