Yes, you can carob chips instead. I would recommend using about 1/2 to 3/4 cups of carob chips. The flavor is similar, but just a bit different, so a little less than you would normally use works perfectly. One reason to use carob chips is that they are chocolate-free, but in this case, most importantly, they are vegan. This can be a good option for people who have allergies to chocolate or for those who want a vegan brownie that doesn’t have as rich a chocolate flavor. With their unique flavor, they add a new dimension to your classic fudgy brownie.
