Line a loaf pan with parchment paper and set aside. Add walnuts to a ziplock bag. Use a rolling pin to crush the nuts into small bits.
Melt coconut oil in a glass measuring cup. Add the cocoa powder, sugar-free maple syrup, pure vanilla extract, and a dash of salt. Whisk to combine. Taste and adjust salt and sweetener if needed. Stir walnuts into cocoa mixture.
Transfer the mixture to the prepared loaf pan and spread into an even layer. A spatula works well for this step. Place the pan in the freezer to allow the chocolate to harden, about 30 minutes.
Slice into bars and serve. Treat yourself to a keto crunch bar or pack one for later when that sweet tooth starts calling!
