Preheat the oven to 375℉. Mist a 9×9 or 8×8-inch baking dish with nonstick cooking spray.
In a bowl, combine the oats, cinnamon, ginger, nutmeg, baking powder, salt, maple syrup, molasses, applesauce, eggs, milk, melted butter, and vanilla. Stir until combined.
Fold in the 1 cup diced pear and ¼ cup of the toasted pecans.
Transfer batter to the prepared dish. Top with a few pear slices and additional toasted pecans.
Bake until the center is set, 30-35 minutes.
Remove the pan from the oven and let sit for 10 minutes before serving.
Garnish servings as desired.
