Preheat oven to 350° and line a baking sheet with parchment paper
In a medium size bowl combine the flour, baking powder, corn starch, and salt.
Attach the paddle attachment to your electric mixer and in the mixing bowl, beat the butter and sugars on a medium high speed until light and fluffy. Approximately 3-4 minutes. Scrape the sides as necessary.
Add the applesauce to the butter and sugar mixture and beat until well combined, scraping the sides so it’s completely combined.
Add ⅓ of the flour mixture until it’s lightly combined, then repeat until all of the flour is blended into the butter mixture.
With a heavy spoon, stir in the oats, pecans, and chocolate chips until they’re evenly incorporated into the mix.
Spoon tablespoons of the cookie dough onto the baking sheet. I usually bake 12 cookies at a time.
Bake for 14-15 minutes or until they are lightly golden brown. Cool on a baking rack.
