These come from Boyajian. I left the peppermint flavoring out of them. I was intrigued by this recipe because it uses both melted milk chocolate chips and unsweetened cocoa powder. I used Dutch process cocoa. They're very moist but unfortunately they don't taste good at all, they taste just like you melted butter, cocoa and sugar together. I added vanilla extract. I used an 8" square pan, not 9", and they baked in 18 minutes, well below the minimum time stated. The top is very firm, which I don't like.
I give these two stars and I don't recommend them.
