Great looking cookies. And the coffee chunks sound good enough to eat out of hand. But my burning question is does the pan warp at high temps? My favorite pan has started to and the only reason I can think why is I have used it several times for drop biscuits that bake at 450. I am in the market for a couple more pans and am open to getting the USA pans instead of the more of the one I have now. Hearing a pan go boing in the oven is annoying. You're right there's nothing more annoying than a malfunctioning pan. Our pans are heavy duty and shouldn't warp. Molly @ KAF
