This high protein Wendy’s Frosty dupe is thick, chocolatey, and made with Greek yogurt, frozen banana, chocolate protein powder, cocoa powder, ice, and sweetener.
It has that cold, spoonable chocolate shake texture, but with a higher-protein base you can make at home in about five minutes.
I tested this two ways before getting the texture right. The first version was too loose because the base did not have enough frozen structure. Adding a completely frozen banana helped thicken the blend and made it much closer to a Frosty-style texture.
This is not an official Wendy’s Frosty recipe. It is a homemade, high-protein version inspired by that thick chocolate drive-thru flavor.
The key is using thick Greek yogurt, a frozen banana, enough ice, and a protein powder that blends smoothly. If the mixture looks too thin, add more ice. If the blender gets stuck, add a tiny splash of milk and
