So I made this recipe before and had a slam dunk of success after simply baking them longer than instructions said to. I felt good about my mixing and everything else.

Today I did a double batch and only 2 of them got cooked through. Both the parchment worked out and the silicone did not. One parchment got way too brown and the other was a bit pale. The silicone mat ones didn't form a bottom and got brown on top (see photo). I baked them 150 for 15 min then had to two two more 1 minutes and still not done inside after 18 minutes.
I have an oven thermometer and it's on. I rotate the cookies once since the back gets more browned. The only recipe issue I think is that I did add about 1 tsp of powder color but that is to a double batch so very small %. Last time I also used powder color and had no issues. My chocolate recipe works fine on parchment and on silicone.
Please help me. I want to sell some next week next to the chocolate but after 4 goes at it, I still am having issues!
