Slender Mug Cake Mix lands a white chocolate flavor with a marshmallow twist

Protein World White Chocolate Marshmallow Slender Mug Cake Mix

Just last week, Protein World revealed and released another flavor for one of its protein supplements in Whey Protein Concentrate, which, true to its name, is a whey concentrate-powered protein powder. The flavor was a sweet White Chocolate Deluxe, and now roughly one week later, the brand has a similar option to add to another one of its ever-expanding products.

Protein World has launched its Slender Mug Cake Mix — a supplement to conveniently and efficiently make high-protein mug cakes — in White Chocolate Marshmallow. The product is in stock and available starting this week through the brand’s online store at £14 (16.85 USD), and like that, White Chocolate Whey Protein, White Chocolate Marshmallow is a limited-time item.
