- Decarb the Cannabis: Preheat your oven to 240°F (115°C). Break up your cannabis into small pieces and spread it evenly on a baking sheet lined with parchment paper. Bake for 30-40 minutes, stirring halfway through. 
- Prepare the Crackers: Spread a layer of peanut butter on one side of each cracker. Be generous but don’t overdo it. 
- Add the Cannabis: Sprinkle the decarbed cannabis evenly on top of the peanut butter-covered cracker. 
- Assemble the Firecracker: Place the second cracker on top of the cannabis-covered cracker to create a sandwich. 
- Bake (optional): Wrap your firecracker in aluminum foil and bake at 350°F (175°C) for 10-15 minutes to activate the cannabis. If you prefer not to bake, you can skip this step and enjoy as is. 
- Cool and Enjoy: Let the firecracker cool for a few minutes, then enjoy! If you want a stronger effect, wait an hour before having more, as edibles take time to kick in.
