Preheat oven to 350°F. Generously butter 9x9x2-inch metal baking pan. Line rimmed baking sheet with parchment. Using on/off turns, blend first 4 ingredients in processor until coarse meal forms. Add pecans; using on/off turns, process until nuts are chopped. Add oats; process using on/off turns until mixture is moistened but not clumping. Press 3 1/2 cups crumbs onto bottom of prepared square pan (do not clean processor). Transfer remaining crumbs to lined baking sheet.
