Carob chips are an edible product, similar to chocolate chips, made from carob. They are used in baking and in trail mixes, often serving as a substitute for chocolate chips. The color is the same as that of dark chocolate, although the taste is somewhat different, with slightly nutty and bitter overtones. Their appearance is nearly identical to a regular chocolate chip. They are made using carob powder, which has the same look, color and texture as baking cocoa.
Carob chips are a safe chocolate alternative for dogs.[1]
