In a large mixing bowl, stir together the sugars and pumpkin. Then stir in the yogurt, eggs, and vanilla extract until just combined.
Add the flour, baking soda, baking powder, salt, and cinnamon to the bowl. Stir together until everything is well combined.
Fill each lined or buttered muffin cup 2/3 with the batter. Top with granola. Bake at 350°F for 20-22 minutes, until a toothpick inserted in the center comes out clean.
