Step 7: Grab about 1 tablespoon worth of marshmallow and place it in the center of the flattened dough.
Step 8: Fold the dough up and around the marshmallow until it's almost completely encased.
Step 9: Sprinkle the tops of the cookie dough balls with more crushed graham cracker crumbs. Chill the dough in the fridge for at least 45 minutes.
Tips for Making the Marshmallows
Boil the sugar and agave together until they reach 240F.
After boiling the sugar, pour the sugar into a mixing bowl with the gelatin and whip it for just a few minutes. It will only need to whip for 2-4 minutes before it's ready!
Whip the marshmallow until it's thick and larger in volume. It will be very sticky and gooey. Stick the marshmallow in the fridge to firm before using.
Spray your hands with non stick baking spray before handling the marshmallow so it doesn't stick to your hands.
Storage and Freezing Instructions
Store the marshmallow in a sealed container at room temperature for up to 3 weeks.
Once baked, keep the cookies in a sealed container or wrapped tightly on a baking tray for 2-3 days.
To freeze the cookies, once filled with the marshmallow, place on a tray and freeze them until solid. Then store the cookies in a container in the freezer for 3-4 weeks.

Expert Tips
- Always spoon measure your flour when baking- This means using a spoon to fluff the flour first, then spoon it into your measuring cup. This will give the most accurate results when baking without a kitchen scale.
- Let the dough chill- Let the dough chill for at least 45 minutes to an hour. This will help the marshmallow stay in the center of the cookie while it bakes and not spill out over the sides. If you can keep them in the fridge for at least 24 hours, that's even better!
- Drop the tray after baking- When the cookies come out of the oven, give them a nice drop on the counter to flatten the cookie even more.
