Burnt cookies is fix-able. If they look done in the oven, they will be over-done when you take them out.
Every December we make Mr.FF’s mom’s great-aunt’s “ice box cookies.” This has been a tradition in his family for decades so he asked his mom to give me the recipe. I should be flattered that he says I make them just like his mom— but they’re a real pain to make. Fortunately, he loves them so much that he helps when we make them... he’s in charge of the oven and if they come out burnt, it’s not MY fault!! It works very well for us.
Yeah....I fix a few of the burnt cookies -——by scraping the burnt stuff off the back....then the rest of the batch goes to the birds. Never fails. I gave up years ago. lol. Sound like you really have things figured out putting him in charge of the oven..lol. Very smart....
