In a large bowl, combine flour, oats, salt, cornstarch, cinnamon, nutmeg and baking powder.

In the bowl of your stand mixer, cream together butter, vegetable oil, honey and sugars over medium speed until smooth. Beat in egg and vanilla extract. Slowly add flour mixture until fully combined. Stir in chocolate chunks. Cover and place dough in the fridge for 30 minutes to chill.

In the meantime, preheat oven to 350 degrees.

Line a baking sheet with parchment paper and drop generous sized rounded balls of cookie dough onto the baking sheet.

Bake cookies for 10-12 minutes or until a toothpick runs through to cookie and comes out clean.

Remove cookies from the oven and transfer to a cooling rack.
