Place nuts into blender and puree until oils are released and you are left with a smooth nut butter. Separately, pour chocolate into microwave safe bowl and cover with 1 tsp avocado oil. Heat at 30 second intervals and stir, until chocolate is completely melted. Add to blender and puree. Lastly, add in espresso beans and give a few quick pulses so that you are left with small chunks of espresso beans, but not so finely ground that you cannot feel their texture. Grab a spoon and go to town!
