Preheat oven to 425F. Line a 12-cup muffin tin with muffin liners and set aside.
Place oats in a medium nonstick pan and set over medium heat. Stir oats around 4-6 minutes until fragrant and a light golden brown. Pulse oats in a food processor several times until finely chopped or finely chop with a knife. Set aside to cool.
In a large bowl, whisk sugars, pumpkin, oil, eggs, yogurt, and vanilla until smooth.
In a separate medium bowl, combine cooled oats, flour, baking powder, baking soda, pumpkin pie spice, and salt. Gently fold flour mixture into liquid mixture until batter is just combined.
Divide batter between prepared muffin cups, filling cups to brim with batter. Set aside for a moment.
