Preheat oven to 375 F. Spray two cookie sheets with cooking spray.

Combine Neufchtel cheese, melted butter, sugars, and vanilla in the bowl of a stand mixer. In a separate bowl, combine flours, oats, baking soda, and salt.

Begin to beat cream cheese, butter, and sugar mixture on medium speed, scraping down sides of bowl as necessary. When creamy, add in the egg and egg yolk one at a time, beating well after each addition. While still beating, slowly pour in the flour mixture. When well mixed, stop beating and stir in the chocolate chips.

Use a soup spoon to drop scant spoonfuls about 2 teaspoons of batter onto sheets. Flatten cookies with your fingertips or with the back of the spoon. Bake for 10 to 12 minutes, depending on how well done you like your cookies.
