Preheat oven to 350°F. Line baking sheet with parchment paper or silpat mat.
Mix all ingredients except Oreo in a small bowl until smooth dough forms. Add in Oreo cookie and crush into dough, until only small cookie crumbs remain. Gather dough, forming cookie shape and place on the middle of baking sheet.
Bake for about 11 minutes until edges turn golden brown. Let cookie cool on sheet. It will initially be puffy and then sink down. Let cookie set for a few minutes before removing and eating.
