I have always used Keebler Club crackers at 320F for 20 minutes (with no tinfoil), and they always came out perfectly. Never burnt or undercooked. Different high. Not as strong, but lasts longer, unless you eat a lot. (For me, it's 2 or more to get really high, and one to just chill.) The crackers don't turn brown, and they taste like peanut butter sandwiches which is exactly what they are.imp:
