Preheat oven to 350 degrees. Line sheet pan with parchment paper.

In large bowl, mix the brownie mix and flour.

Next, mix the eggs and vegetable oil into the dry ingredients until well combined. It is a very thick dough, so you make have to knead by hand.

Stir white chocolate chips into the cookie dough.

Drop rounded tablespoons of dough onto the prepared baking sheets. I like to use a cookie scoop for this so that they're all the same size.

Bake cookies for 10-12 minutes. Baking time may vary depending on your oven. If they aren’t quite done, let them bake an extra minute or two and check them again.

Let cool for about five minutes on cookie sheet and then transfer to wire rack to finish cooling.
