Why A Cookie Mix? Take away the stigma that cookies are just an indulgence and itâs clear that homemade cookies from Skratch are a great alternative to prepackaged energy bars. Compared to most energy bars, cookies are nutritionally similar and easier to eat and digest because theyâre simpler, have more moisture, and lack excess ingredients. Skratch Labs makes it simple to bake up portable cookie bars or standard cookies in less than 30 minutes. All you need is a stick of butter, an egg, and your favorite chocolate chips, fruit, or nuts to mix in.
