Preheat the oven to 350 degrees.

In a medium bowl, sift together the flour blend and coconut flour and mix in the baking soda and salt. To the same bowl, add the cane sugar, brown sugar, coconut oil, milk, vanilla, and beaten egg. Using a wooden spoon or a hand mixer, mix ingredients together until well combined. Dough will be on the thick side. Stir in the chocolate chips and walnuts.

Drop dough balls onto a cookie sheet lined with parchment paper. Bake for 8-10 minutes or until they’re slightly golden on top, but still very doughy inside. Take them out while they’re still pretty underdone in the middle: they will continue cooking as they cool. Let them sit on the pan for one or two minutes and move them to a wire rack to cool.
