Baking great chewy oatmeal cookies with Quaker Instant Oatmeal Fruit packs
You probably could, but it'd be a little difficult to get right.

You'd want a recipe that calls for instant oats, since that's what's in your packets. And they're also close to 1/3 sugar by weight, so you'd need to reduce the sugar in the recipe. Depending how much of the sugar that ends up being, that could cause additional problems, because creaming sugar and fat together is an important part of many cookie recipes. If most of the sugar isn't available to cream with the fat, you'll get a different texture than the recipe intended.

So I'd suggest searching for "instant oatmeal cookie recipes" or similar, to try to find recipes that are actually intended to be made with instant oatmeal packets. You'll probably have a harder time finding really good, reliable recipes than you , but I'm sure you can find something that's good enough.
