Just threw my first batch ever into the over about 6 minutes ago. Used around a gram total of both finely ground KB and kief. Used organic peanut butter instead of Nutella, cuz I found organic PB that has 17grams of fat for the same serving size that Nutella only had 11, so we'll see. They're kinda messy, so I layed larger crackers underneath the actual firecracker to catch any spillage. Used chocolate flavored graham crackers, in case anyone is wondering.
