Yes, Yum Crumbs is a legitimate company. It was founded in 2020 and offers a variety of crumbs, sugar, sprinkles, and other topping ingredients. The products are ready to use straight out of the package and can add extra flair to pastries, ice cream, and other desserts. The company has gained popularity and even appeared on the TV show "Shark Tank". The products have received high marks on Amazon where they bear a 4.9 rating from consumers. They're shelf-stable and just as good to snack on as they are lying on top of cakes and donuts. They can even be stirred into cereal and oatmeal or tossed on top of pancakes. Yum Crumbs also sells gluten-free versions of its toppings and has added a new product called Sour Powder to the product line-up. It's a family affair, with the founder's wife, Amanda, co-owning the business, and their five children all promoting the product on the company's social media accounts.
