In a high-powered food processor, blend cottage cheese, maple syrup, and vanilla extract until creamy, usually 2-4 minutes.
Add Oreos to the mixture and pulse until they break into chunks. You can adjust the chunkiness to your liking.
For frozen yogurt consistency, transfer the mixture to a large plastic bag, removing air, and freeze for 2 hours. For ice cream consistency, use a loaf pan or freezer-safe container, cover, and freeze for at least 4 hours.
Once frozen, for frozen yogurt, snip the corner of the plastic bag and pipe into cups or cones. For ice cream, let it thaw for 15 minutes and then scoop into bowls.
Top with crushed Oreos and enjoy!
