Preheat oven to 350 degrees F. Grease a 9×9” baking pan, set aside.
In a small whisk together the oats, flax seed, pumpkin pie spice, cinnamon, nutmeg, ginger, baking powder, and salt. Set aside.
In a large bowl, whisk the egg, almond milk, pumpkin puree, maple syrup, and vanilla until combined.
Add dry ingredients to the wet ingredients and stir until completely combined. Let sit for about 3-4 for the oats to absorb some of the liquid. Top with chopped pecans or pumpkin seeds if desired.
Bake for 30-35 minutes or until the top is set and slightly browned. Remove from oven and let cool.
Slice and top with a drizzle of maple syrup.
