No, Sludge is not allergen-friendly. All flavors contain milk and egg, and some varieties may also include peanuts, gluten, or tree nuts. Because production is done under New Jersey Cottage Food Laws, all products may contain trace amounts of these allergens.

Sludge is currently available for purchase in New Jersey only.

The nutrition label and ingredients are listed with each flavor in our Shop page.

For optimal taste, texture, and protein content, we recommend using plain Greek yogurt. Its naturally thick consistency creates the rich, indulgent texture that defines Sludge while helping keep the protein content high.

You can experiment with other yogurts, but keep in mind that Sludge is already flavored and sweetened, so results may vary.

Check out our Sludgosopher's Guide page to see more of our recommendations and uses.

To our knowledge, there are no high-protein sweet dry blends that turn yogurt into cookie dough and more in seconds. While Sludge is inspired by high-protein yogurt desserts popular on social media, we are the first to package this concept into a convenient, ready-to-use mix.

No, and we don't want to be!

While Sludge delivers the benefits of protein, it's designed to transform your yogurt into a thick, indulgent, dessert-like experience—something protein powder alone can't do.

Plus, Sludge includes real add-ins like chocolate chips or walnuts, giving you texture, flavor, and satisfaction beyond a typical protein powder.
