Step 1

Place all ingredients except chocolate chips and walnuts in a food processor.

Step 2

Blend until completely smooth and creamy, scraping down the sides as needed. Once smooth, fold in walnuts and chocolate chips by hand with a rubber spatula.

Step 3

Spoon into an air-tight storage container and refrigerate for at least two hours or ideally overnight before serving. The dough will get much thicker once refrigerated, so resist the urge to taste at this point! The oat flour and solidified coconut oil will firm up the cookie dough and dramatically improve the texture and flavor, so letting it refrigerate before serving is essential.
