Put cookie crumbs and cream cheese in a food processor and extract, if using it. Pulse until mixture is combined and forms a large ball. Mixture should not be crumbly and hold together, but not be too sticky to form into balls. See notes if not the case.
Form small balls of cookie mixture (*a great part to let kids help with!) and place them on a tray sprayed with cooking spray to prevent sticking. Freeze until hard, 30 min-hour.
Remove from freezer. Melt chocolate chips in the microwave or on the stove. Dip each frozen cookie ball in the melted chocolate and place back on tray. We make this process easier by stabbing each frozen ball with a toothpick for dipping, then removing once placed on tray and covering up the hole with a small dab of melted chocolate.
*If using GF/DF Oreos, use 1 package regular-stuffed Oreos + 4 oz DF cream cheese. This makes 24 truffles.
For even more simple ingredients that are also Paleo, use Simple Mills Crunchy Double Chocolate cookies.
I put the cookie measurement in crumbs, as each box/brand of GF cookies will be different. So, smash them in a bag or pulse them to crumbs in your food processor/blender and then measure out the 4 cups of crumbs. If you end up with a different amount of crumbs with your cookie brand, it's 1 cup crumbs + 1 oz cream cheese (1:1 ratio).
If you have mixed the cream cheese and crumbs in the food processor and it's dry, add a little more cream cheese. If it's too moist (not clumping into a non-sticky ball), add more cookie crumbs.
