Preheat your oven to 350°F (175°C).

Line an 8x8-inch baking pan with parchment paper and lightly grease it.

In a medium mixing bowl, combine flour, rolled oats, pumpkin pie spice, salt, and baking soda. Stir until well blended.

In a larger mixing bowl, whisk together eggs, pure pumpkin puree, natural applesauce, light brown sugar, and vanilla extract until smooth.

Gradually add the dry mixture into the wet batter, stirring gently until just combined. Don’t overmix.

Fold in half of the pepitas and chopped pecans.

Pour the batter into the prepared baking pan and evenly spread it out.

Sprinkle the remaining pepitas and chopped pecans on top.

Bake for 25-30 minutes or until a toothpick inserted comes out clean.

Allow the bars to cool in the pan for about 10 minutes, then lift them out using the parchment paper and transfer to a cooling rack to cool completely before slicing.
