Combine all ingredients in a blender. Blend on high speed until the mixture is smooth and creamy, with no lumps remaining.
Pour the mixture into a shallow dish or ice cube trays and place it in the freezer. Allow it to freeze for about 4-6 hours or until it becomes firm.
Once the mixture is frozen solid, remove it from the freezer and let it sit at room temperature for a few minutes to soften slightly. Transfer the partially thawed mixture back to the food processor and process until it becomes crumbly. Add in your cookie dough and process until combined.
