Bottom line: Roasted nuts, seeds, and nut butters are cottage food eligible with no license needed — just make sure peanut and tree-nut allergens are impossible to miss on the label.
The Path
Nuts and seeds are a common, low-friction cottage food category under § 500.80. The one detail worth extra care is allergen labeling: peanuts and tree nuts are top-8 federal allergens, and they need to be clearly declared even when the nut is the entire product rather than a hidden ingredient.
What You Need
Sell roasted/raw nuts, seeds, nut butters, or trail mix as shelf-stable products
Label with business name & address, product name, ingredients, net weight
Prominent allergen declaration for peanuts/tree nuts
Watch Out For
Don't under-declare allergens just because the nut is the obvious main ingredient
