I don’t have a good recommendation for you, although to save you trial and error, I have an anti-recommendation. I bought the Made Good Organic Baked Cookie Bites, which are individually packaged and are 120 calories. They were edible, but extremely unsatisfying so that you would want at least three packages and you would still be unsatisfied. Do not recommend.
If you find anything that hits the spot, please report back because I would love to find something as well. The pre-cut brownie squares at Trader Joe’s are not bad and the first night I was able to only eat one, but that went out the window by the second night and I was eating multiple at the same time, so I won’t be buying them again.
