With another week comes another release from the UK brand Protein World, which has been in headlines as often as once every week or two for the past couple of months. The brand is back again to close out June with another flavor expansion of its functional baking mix, Slender Mug Cake, that can be turned into a delicious, high-protein mug cake in less than a minute.

Like its flagship protein powder Slender Blend, Protein World’s Slender Mug Cake comes in a strong selection of flavors, totaling well over ten and including the likes of Gimme S’more, Salted Caramel, Jammy Biscuit, and Birthday Cake. Joining the baking product’s already extensive menu this time around is something a little more traditional with Cookies and Cream.

As per usual, the best place to get the latest from Protein World is its online store at, where a 12 serving bag of Slender Mug Cake will cost you £12.99 (18.00 USD).
