Method
Preheat the oven to 350°F and lightly grease an 8x8-inch baking dish with cooking spray or coconut oil.
In a large mixing bowl, combine the oats, protein powder, baking powder, cinnamon, nutmeg, and salt. Stir until evenly mixed.
In a separate bowl, whisk together the pumpkin puree, almond milk, maple syrup, egg, vanilla extract, and melted coconut oil until smooth.
Pour the wet ingredients into the dry ingredients and stir until fully combined. The mixture should be thick but pourable.
Transfer the batter to the prepared baking dish and spread it evenly with a spatula. Sprinkle the chopped pecans evenly over the top.
Bake for 25-30 minutes, or until the edges are golden brown and a toothpick inserted into the center comes out clean.
Let the baked oats cool for 5-10 minutes before slicing and serving. They should be firm but slightly soft in the center.
